Restoring Weather Stained Terrazzo Steps in Glasgow

The photographs below are from a set of Terrazzo steps outside a house in Glasgow which had completely lost their colour after being subject to years of weather staining and believe me we see all sorts of weather up here in Scotland. The owner of the house wanted them restoring back to their natural state but naturally concerned about safety didn’t want them shiny or slippy in anyway.

Cleaning Terrazzo Steps

I could see tackling the different surfaces of the stone stairs would be tricky so rather than opt for a cleaning product I decided to use a set of diamond encrusted burnishing pad fitted to a handheld flex machine.

I started with the very coarse 50 grit pad lubricating along the way with a little water and moved up through the medium and fine pad until the job was finished. Now normally when working on stone this is followed up with the application of a very fine pad to restore a polished appearance but clearly in this case that would not be necessary. In between the application of each pad the steps were rinsed with water to remove the slurry generated in the burnishing process.

One complete I left them to dry out for a few days; fortunately I had timed my visit within a warm weather window so I was confident they should be dry when I returned.

Sealing Terrazzo Steps

I returned a few days later and after checking the stone had indeed dried out I sealed the Terrazzo with three coats of Tile Doctor Colour Grow which is a breathable impregnating sealer suitable for external application. Being an impregnator it protects the stone from within by occupying the pores in the stone where dirt might otherwise become ingrained, it also enhances the natural colours in the stone and as you can see from the photograph below the steps now look much pinker.

Terrazzo Tiled Hallway Polished in South Wales

Terrazzo is a quite a bit different from the natural stone floors we most commonly work with. It’s a type of flooring material that was made popular by Venetian builders in Italy in the 1920s, but is ultimately descended from styles of design that date back hundreds of years. A typical Terrazzo floor consists of chips of marble or granite set in concrete and polished to result in a smooth surface.

This Terrazzo floor, installed in the hallway of a property in Bridgend, South Wales, was in relatively good physical condition, but it had clearly lost its shine due to the build-up of dirt and muck over the years. In fact, it was first installed in around 1940! The owner was keen to have it rejuvenated to its best possible condition, so they asked me to come in to see what I could do.

Cleaning and Burnishing a Dirty Terrazzo Tiled Floor

My first course of action was to apply Tile Doctor Pro Clean liberally across the floor and leave it to dwell for a short period. This is a high alkaline cleaner that is designed to deal with light to moderate soil build-up, and to strip away any old sealer remaining on the floor. I scrubbed the product in using a black pad fitted to a rotary machine and vacuumed up the resulting cleaning with a wet-vac machine.

Next, to restore the shine to the floor, I undertook a process known as burnishing, which involves the application of diamond encrusted polishing pads. We will typically start with a Coarse grit pad to level off any uneven areas of the floor and grind down any particularly stubborn marks and stains. Then, we gradually refine the polish on the floor using Medium and Fine grit pads. A small amount of water is used as lubrication with each pad.

After I had finished applying the first three pads in our four-pad system, I gave the floor a thorough rinse and left it to dry overnight.

I returned to the property the next day and immediately ran some damp tests to check for excess moisture issues, which one might expect with an old floor like this one. Thankfully, the floor proved dry – and I could finish the burnishing process with the fourth and final Very Fine diamond encrusted burnishing pad, which achieved a beautiful shine finish.

Finally, I sealed the floor with three coats of Tile Doctor Colour Grow, an impregnating sealer which provides robust protection and enhances the coloured patterns in the Terrazzo.

As you can see from the photos above, the floor is looking so much more colourful and bright after a deep clean, polish and a fresh seal. The customer was over the moon!

Old Terrazzo Restaurant Floor Fully Restored in North Wales

The Washington Hotel in Llandudno, North Wales, is a truly historic building and one of the enduring features on the promenade of the sea resort. This beautiful part of Wales was the holiday destination of choice for Lewis Carrol, the famed author of Alice in Wonderland, and you can see several statues of him in and around the town.

The Washington Hotel first opened in 1855, but was rebuilt in 1925 after being destroyed by a fire. The building most recently served as a nightclub, before it closed in 2012. Now, there is ongoing renovation work to turn it into a restaurant.

As part of this renovation work, we were asked to restore bring the old Terrazzo floor back to life, which was certainly worse for wear after nearly a century of use. It had been covered in carpet, as well as old vinyl tiles, and was very heavily soiled with dirt and ingrained muck. This area of floor would eventually act as the entrance to the restaurant and bar area, so it was important to get this right for the customer.

Burnishing a Terrazzo Tiled Floor

There were three areas we were asked to restore, covering 36 square meters in total:

• Circular foyer (27 square meters)
• Internal entrance area (2 square meters)
• External entrance stairs: (7 squares meters)

We started the restoration process with the application of a Very Coarse 50 grit diamond pad to tear away all the old carpet and vinyl resin, clearing the area to allow us to work directly on the Terrazzo tiles. With the tiles exposed, we discovered two large, long cracks in the base of the floor, so we filled these with a flexible floor grout. We chose to use this instead of a resin compound because resin isn’t very flexible, and if there is any movement the crack will become exposed again after six to 12 months. A flexible floor grout will move with the contractions and expansions of the base, and if the movement is not too extreme the flexible grout will not crack in the future.

We then continued through our system of diamond burnishing pads, applying the 100, 200, 400, 800, and 1500 grit pads with a small amount of water as lubricant. Once the floor was fully dry we applied the final 3000 grit pad, which is the finest of the pads and produces a very high quality polished effect on the stone.

Once the floor had been polished, it needed to be sealed in order to protect it from dirt becoming ingrained into the pores of the stone. We did this using firstly two coats of Tile Doctor Colour Grow, which is our impregnating, colour-enhancing sealer. The sealer works by penetrating the pores of the stone to fill them and block trapped dirt and stains. We then left the floor to dry off fully overnight.

The next day, we returned to the building to apply a crystallization powder known as Tile Doctor Shine Powder, which further enhanced the shine we had built up on the floor and give it extra sealer protection.

The customer was exceptionally happy with our work, as the restoration of the Terrazzo tiled flooring is an essential part of the renovation project overall. We wish them all the best in the eventual opening of the new restaurant!

For aftercare, we recommended to the customer that the floor is maintained with Tile Doctor Stone Soap as this will not only clean the Terrazzo without damaging the sealer like many stronger cleaners, but also maintain its patina as well.

Restoring Old Terrazzo Kitchen Tiles in Cheshire

This post is from the small Cheshire village of Bosley where I had received an enquiry from the owner of the old station master’s house. The house was quite old and the owner had been modernising it whilst keeping many of the original features. This includes some fantastic Terrazzo kitchen tiles which unfortunately were not looking their best due to an abundance of ingrained dirt. The floor was well overdue to be restored by a professional, so we were called in to get the job done.

Terrazzo Kitchen Tiles Before Cleaning in Bosley Cheshire

Terrazzo is a very hard wearing and affordable material that was quite common in many public buildings so I suspect this floor was original.

Terrazzo Kitchen Tiles Before Cleaning in Bosley Cheshire

Burnishing a Terrazzo Tiled Floor

Terrazzo is very hard wearing so we find the best method to clean them is to treat them like a Marble or Travertine and use a process we have developed called ‘burnishing’. This process cleans and polishes the tiles using a system of four 17″ diamond-encrusted burnishing pads of varying grits in conjunction with a little water as lubrication.

We started by applying the Coarse 400 grit pad to grind away the stubborn ingrained dirt, a little water is used to lubricate and then the floor is rinsed to remove the slurry that is generated. We then worked our way through the system to a Medium 800 grit pad, Fine 1500 grit pad and finally a Very Fine 3000 grit pad each one applied in the same way.

This process carefully refines the polish of the surface of the tiles, restoring shine and lustre while ridding the stone of ingrained dirt. Once the burnishing had been completed, we gave the floor a thorough rinse to remove dirty water and soil residue the floor. It was then left to dry overnight.

Sealing a Terrazzo Tiled Floor

The floor had dried by the next day, so the tiles were ready to receive a fresh seal to protect against ingrained dirt and make them easier to keep clean in the future.

Our choice of sealer for this floor was Tile Doctor Colour Grow, it’s an impregnating sealer that’s specially formulated to enhance the natural colours in the tiles. As an impregnating sealer, Colour Grow fills the pores in the stone to act as a barrier against muck.

Before we left the customer to enjoy their newly restored Terrazzo tiles, I made sure to use a rotary machine fitted with a white pad to gently buff the floor and make sure the finish was pristine.

Deep Cleaning Terrazzo Hallway Floor

This Terrazzo tiled hallway at a property in Northampton was in a really bad state. It was heavily soiled and suffered from glue marks where the original carpet covering it had been removed. Additionally, there was some damage to the edges of the doorway, and a large crack in the floor running across the width of the hallway.

Terrazzo Hallway Northampton Before Cleaning

Terrazzo is an interesting material, originally produced in Italy, that consists mainly of concrete with segments of marble and other stone interspersed and held together with a resin. Since Terrazzo is formed in this way, I explained to the customer that I would fill the crack along the floor and the small holes around the edges with concrete, before then using tile paint to match in the colours as best as possible. This would be the most cost-effective solution, which was ideal since the customer had a limited budget for the repairs.

Terrazzo Hallway Northampton Before Cleaning

Before beginning the restoration, I tested a small area using a diamond encrusted burnishing pad, thereby giving the customer an indication of the type of results that could be achieved. With the customer pleased by the results, the job was booked in for the following week.

Cleaning and Burnishing a Soiled Terrazzo Tiled Hallway

To begin, Tile Doctor Remove & Go was applied to the floor and was left to dwell for ten minutes to soften the carpet glue and break down any old sealer. This was then scrubbed in to the tiles with a pad fitted to a rotary machine. To remove the remaining residue and marks in the particularly stubborn areas, I used a manual hand scraper. The entire floor was then wet vaxed to soak up the soiled cleaner and leave the area clean for burnishing.

This was followed by the use of Tile Doctor diamond encrusted burnishing pads to polish the tiles, starting with a coarse grit pad, followed by wet vaxing and repeating the process with a medium grit pad and finally the fine grit pad to achieve the desired effect. I then installed a turbo dryer to dry the floor.

I returned to the property once the floor was dry and carried out the repairs which had been discussed earlier with the customer (filling the holes and cracks in the floor with concrete), cleaning off any concrete residue before I finished for the day.

Upon my return to the property the next day, I refined the polish on the floor even further by applying the extra fine grit burnishing pad.

To finish off the three day restoration, I sealed the Terrazzo tiles using two coats of Tile Doctor Colour Grow sealer. As an impregnating sealer, Colour Grow soaks into the pores of the stone, protecting it from ingrained dirt. Colour Grow also contains colour intensifying properties, allowing it to enhance the naturally occurring shades in the stone, and therefore stopping it from appearing dull.

This floor certainly was in a bad state, with damage as well as dirt to deal with, but I’m pleased to say that the work went a long way in transforming its appearance, leaving a very happy customer.

Restoring the Appearance of Terrazzo Floor Tiles

Every so often I will get the chance to undertake tiled flooring restoration work in public buildings, and late last year I was asked to clean and seal a Terrazzo floor at a church in Redhill. The floor wasn’t in great condition; not only was it suffering from a significant amount of dirt due to a lack of proper maintenance, but it was also marked by several cracks. Overall, the appearance of the floor was very displeasing and the church was keen to have me in to complete some repairs, along with a deep clean and seal.

Cleaning and Burnishing a Terrazzo tiled floor

Upon initial inspection of the floor, I was unable to say for certain whether there was any old sealer remaining on the tiles so to ensure it was removed I began the cleaning process by applying a layer of Tile Doctor Remove & Go, which is a powerful cleaner/stripper designed to both break down old layers of sealant and lift out any ingrained dirt.

I then gave the floor a rinse with water to remove any excess cleaning product, before moving onto a different cleaning process, known as burnishing. Burnishing involves polishing the surface with to achieve an aesthetically pleasing sheen finish. The Tile Doctor burnishing system consists of four diamond encrusted burnishing pads with different levels of grit.

I began by applying a Coarse burnishing pad, before working my way through the system with Medium, Fine and finally Very Fine pads to achieve a very refined, high quality polished finish, you need to use a little water to help lubricate the burnishing and you need to rinse the floor after each pad to remove the slurry.

Once the floor had been allowed to dry completely following both cleaning processes, I set about filling the cracks in the tiles with two part resin stone filler.

Then, once the filler had dried, I re-polished the floor using only the extra fine burnishing pad, focusing my attention along the crack lines. This really helped to reduce the evidence of cracks and left instead a smoothed surface.

The final stage of the restoration involved sealing the Terrazzo tiles with Colour Grow, which is Tile Doctor’s colour intensifying sealer that impregnates the stone seeping into its pores to provide protecting the floor from within with a robust seal capable of withstanding the high amount of traffic experienced by church floors. The last step was to buff the entire area with a soft white buffing pad.

The church was very pleased with the results, especially that they were able to show it off for last year’s Remembrance Sunday and left the following comment on the Tile Doctor feedback system:

“Many thanks for the work on our Terrazzo floors. It’s only when you see the before and after that you realise how grubby they had become. We have had loads of complimentary comments as to how good they look. Bill Bailey was a very personable and professional contractor who put himself out to work around our requirements and others working in the buildings at the same time. More than happy to recommend the company and Bill personally. Many thanks for a job well done.”

Re-Sealing a Terrazzo Floor

For this job, I paid a visit to the bustling town of Windermere in South Cumbria. My client asked me to refinish a black and white Terrazzo tiled entrance and hallway floor. Terrazzo if you’re not familiar is a very interesting and beautiful stone of Italian origin, which has been used for flooring in houses for centuries.

We had previously quoted to do the work on this floor however the customer has also received a quote from another firm in Glasgow and had chosen to go with them solely because they were more expensive. However, it stands to reason that the most expensive companies are not always the best quality and Tile Doctor prides itself on the amount of customer feedback we display on our websites which we believe is a far better indicator.

On the arranged day no one from the Glasgow firm showed up and after following up with the firm a young man in his early 20s arrived five hours late and began work on the floor. According to the customer he spent three days attempting to complete the job, but ran out of time and asked the client to apply the sealer themselves. The client applied the sealer, but as she had never done it before the floor turned out blotchy in appearance and she was far from happy.

To cut a long story short, my client complained to the Glaswegian company, after all she had paid for a full service and not received it. Unable to get a satisfactory conclusion from them she decided to call in Tile Doctor to put the matter right. I must point out that although I have included before and after photos one this post it’s really difficult to appreciate the extent of the problem without seeing the floor in real life.

Re-Applying Sealer to a Terrazzo tile floor

To resolve the sealer, and to provide my client with the polished finish she had originally wanted, I burnished the floor using a set of four Tile Doctor Diamond encrusted burnishing pads. Each of the four pads has a different grit: I first applied the coarse pad and worked my way through medium, fine and eventually very fine using a little water to lubricate and rinsing the floor between each pad to remove any residue; after the burnishing process was complete I gave the entire floor a final, thorough wash.

I then used a wet-vac machine to extract the water and get the floor as dry as possible before leaving for the day and allowing it to fully dry completely overnight, it’s very important that the floor is as moisture free as possible before being sealed as it can affect the final result.

The next day I returned to the house and sealed the floor with two coats of Tile Doctor Colour Grow, an impregnating, colour-enhancing sealer that really accentuates the look of the black and white tiles.

Now that the problem has been resolved, my client is very happy with the condition of her Terrazzo tiled entrance and hallway floor.

Filling a Cracks in a Terrazzo Floor

A few months ago I was called down to the coastal town of Southend to restore a damaged Terrazzo tiled floor. Terrazzo is a very beautiful type of stone of Italian origin, and has been used for hundreds of years for residential flooring. The problem with this floor was a significant crack in the surface that was not only spoiling the appearance of the Terrazzo, but also posed a potential hazard for anyone walking in and around this area. I was also commissioned to give the floor a thorough clean and seal .

Repairing a crack in a Terrazzo flooring

To begin the repair, I first mixed a strong solution of one part Tile Doctor Pro-Clean to three parts clean water. I then applied this solution to the hole and the surrounding area, making sure that any dirt and muck had been completely removed before filling. Pro-Clean is a versatile, alkaline cleaner recommended for cleaning natural stone floors.

The damaged area was then dried using an air blower to remove any moisture from in and around the hole, paying special attention to the tricky cracks that were not so easy to dry. The cracks were then filled with a stone glue and hardener. Once the filling had been completed I gave the area a coat of acrylic paint mixed with glue to match the original colour of the floor as much as possible. The final stage in the repair process was sanding down the treated area to achieve a smooth surface that was consistent with the rest of the floor. As you can see from the photograph, the finish came out very nicely however I apologise for the photograph which I appreciate could have been better.

As aforementioned, I was also commissioned to give the floor a thorough clean. I did this using a similarly diluted solution of Pro-Clean and water. The solution was worked into the stone using a black scrubbing pad fitted to a rotary floor scrubbing machine. After completing the clean I rinsed the floor and removed the resulting soil with a wet vacuum, I then left the property to allow the floor plenty of time to dry before being sealed.

I returned the next day to seal the floor using Tile Doctor Shine Powder. The crystallised powder is applied directly to the floor and then worked in with a buffing pad. The result is a nice durable shine which had previously become dull over time due to high usage and the breakdown of an old surface seal.

Deep Cleaning Old Terrazzo Tiles

We visited a lady in Luton who had just had a brand new Terrazzo tiled floor installed and had chosen not to have it sealed. Terrazzo is a beautiful tile made from natural stone and as such is very sensitive to acid.

Terrazzo tiles etched with vinegar before restoration

Although this is common knowledge within the tiling industry, the builder who completed the initial installation of the Terrazzo floor did not make the client aware of the stone’s acid sensitivity. What’s more, he actually advised against sealing the floor. This resulted in the client unknowingly using an unsuitable cleaner and left what looked like water splashes all over the floor.

In a desperate attempt to remove the stains she applied vinegar to the floor. Since vinegar is an acid it caused a deep etching and immediately took away the shine of the tile, leaving in its place a dull mark. At this point she decided to contact the Bedfordshire Tile Doctor, and I came along to her rescue!

Burnishing an Acid Damaged Terrazzo Tiled Floor

To remove the etching I used a set of Tile Doctor Diamond encrusted burnishing pads. Since the marks were particularly severe I opted to take the tile right back using an extra fifth pad rather than the usual four. The pads are applied in sequence from Coarse to Extra fine with a little water and a rinse between each pad. After the burnishing process was completed, all of the marks had been removed and were replaced by a beautiful polished shine.

We then sealed the floor using two coats of Tile Doctor Colour Grow which is an impregnating sealer that penetrates deep into the pores of the stone, providing a durable seal from within. This will help protect against dirt and stains in the future, and will also help to lessen the impact of mishaps should the floor become exposed to acidic products again. In addition, Colour Grow is a colour intensifying sealer so, as you can see from the photos, the lovely natural shades of the Terrazzo were accentuated.

With the floor restoration a success, my client was very happy and before leaving I advise her to use Tile Doctor Neutral Tile Cleaner or Tile Doctor Stone Soap for regular cleaning as these products will maintain the floor without affecting the appearance of the floor or degrading the sealer.

Restoring an old Terrazzo floor

I previously restored an Quarry Tiled floor for the owner of this residence near Caerphilly Castle and was asked back to deep clean their Terrazzo hallway floor which was far from looking its best.

Restoring a Terrazzo Floor

Terrazzo is a very hard surface and needs to be burnished to get the best results so after scrubbing the floor with Tile Doctor Pro-Clean and a black scrubbing pad to remove what felt like 100 plus years of black dirt I set about burnishing the floor with a set of diamond encrusted burnishing pads and a little water. The set comprises of four different grades of diamond pads ranging from coarse to smooth that produce a shiny clean surface. The floor is rinsed between pads to remove any slurry from the process and given another rinse at the end.

The hard Terrazzo soon dried and I was able to seal the floor with the application of three coats of Tile Doctor Colour Grow which is a colour enhancing impregnating sealer which will prevent staining and make it easier to clean in future. Once the last coat was dry I and gave the floor a further polish with the 4th stage green pad to give a true deep shine.

Restoring a Terrazzo hallway floor from 1924

I do enjoy breathing new life into old floors as was the case with this Terrazzo tiled hallway floor in Southbourne near Bournemouth, installed in 1924 it had been knocked about by various building alterations and then finally covered in a carpet which had been glued to the floor.

Removing Adhesive from Terrazzo tiles

Stubborn remnants of the carpet adhesive were removed using Tile Doctor NanoTech HBU Remover which is applied to the tiles and then left to soak in for a before being scrubbed in with a black buffing pad and a dilution of Tile Doctor Pro-Clean. HBU actually stands for Heavy Buid-up Remover and it’s a great problem solver that penetrates through tough stains and coatings so they can be easily removed. The floor was then washed down with clean water and any areas that needed further attention were retreated until I was satisfied with the floor was clean and free of glue.

The next step was to re-polish the Terrazzo using a set of of Tile Doctor burnishing pads which are applied in sequence from Coarse through to Super Fine with a little water to help lubricate. The coarse pad removes any surface grime and old sealant and the remaining pads build up the polish to bring back the original shine. The floor is washed down between each pad to remove the soil generated during the process.

Sealing Terrazzo Tiles

Cleaning took most of the day so I returned the next day to apply the sealer testing the floor first to ensure it was dry. To seal the floor I used a couple of coats of Tile Doctor Colour Grow which is a colour enhancing sealer that impregnates into the pores of the stone and prevents contaminates staining the floor.
The customer decided that she would conceal the concrete patches at the edges of the floor using Colours Stone Effect speckled spray paint which is available in B&Q in her own time.

As you can see from the photos the floor looked a hundred times better and the customer was very satisfied with the result.

Deep Cleaning and Old Terrazzo Kitchen Floor

These photographs are taken from an old Terrazzo floor in the kitchen of a house in the busy market town of Oakham, Rutland. The floor was looking rather grubby and now overdue a deep clean to remove dirt and grease from the floor and being a hard polished stone it would also need to be burnished to restore the appearance of the Terrazzo.

Old Terrazzo Floor in Oakham Before Cleaning

Stripping the Terrazzo Tiled Floor

To resolve we deep cleaned the floor by applying a strong dilution of Tile Doctor Pro-Clean which was left to soak in for a good fifteen minutes before being worked in using a rotary machine fitted with a black scrubbing pad. The cleaning solution soon became soiled as the dirt was lifted out of the floor and this was removed with a wet vacuum and the floor then rinsed with water.

The next step was to strip back the surface of the Terrazzo so it could be polished. This is done using a set of diamond encrusted burnishing pads which come in a set of four grades from Coarse to Super Fine. We started with the coarse pad which can remove dirt, sealers and other coatings before moving onto the medium, fine and super fine pads which polish the floor and bring up the surface. The pads use a little water which needs to be rinsed away after each pad followed by a thorough rinse at the end of the process.

At this stage we would normally wait for the floor to dry and then seal it using a product recommended for the particular surface, location and desired appearance however on this occasion the owner was happy to leave the floor the way it was so we were able to complete the job in a single day.

Deep Cleaning Terrazzo Floor

Just to prove we take on any job large or small I thought I would post the details of this small Terrazzo Vestibule that we recently cleaned at the entrance to a house in Glasgow. The Terrazzo was not looking its best which is hardly surprising being in front of the main entrance to the house it must have seen a lot of foot traffic over the years.

Cleaning and Burnishing a Terrazzo Floor

Terrazzo is a very hard surface and as a result it has to be treated in the same way as other hard surfaces such as Travertine, Limestone and Marble which typically involve burnishing the surface to remove the dirt and restore the appearance.

Before burnishing the floor was cleaned using a strong dilution of Tile Doctor Pro-Clean which was left to dwell on the Terrazzo for a while before being scrubbed in by hand due to it being such a small area; following that the floor was given a quick rinse with water and a quick clean with Tile Doctor Neutral Cleaner to remove any trace of strong cleaning product.

The next step was to burnish the floor using a set of four diamond encrusted burnishing pads. You start with a coarse 400 grit burnishing pad which is run over the surface with a little water to help lubricate and this removes surface dirt and coatings such as sealers. Once that was finished we moved onto the medium 800 grit pad which is the first step of the polishing process and also removes ingrained dirt. The surface of the Terrazzo is still quite rough at this stage so once complete with the medium pad the fine (1,500 grit) is used smooth down the surface and continue to build up the polish in the floor. The last pad is a very fine (3,000 grit pad) and this pad builds on the existing polished effect to create a high shine finish.

All these pads are applied with water and the resultant slurry needs to be cleaned off during the process with the final step of giving the floor a thorough rinse with clean water.

Sealing a Terrazzo Floor

Once the floor was completely dry it was sealed using two coats of Tile Doctor Colour Grow which is an impregnating sealer designed to bring out the natural colours in the stone and penetrate into the pores of the tile preventing dirt from getting in there and providing maximum on-going stain protection. The floor was then buffed using a white buffing pad to bring up the shine further and remove any smears left from sealing.
