Restoring the Appearance of Encaustic Cement Tiles in Chipping Norton

Posted on April 26, 2019 by TileProf

The photographs on this page are of Encaustic Cement tiles where the grout had not been wiped off the surface properly after being laid. This in turn allowed dirt to become easily trapped and they soon became grubby. We see this problem a lot at Tile Doctor where it is commonly referred to has Grout Smears or Grout Haze. The customer from Chipping Norton had tried to remove it themselves without success and decided to give us a call.

If you haven’t come across them before Encaustic Cement tiles are often hand painted and are available in a range of beautifully artistic patterns. Being cement based however they do need to be sealed for best results.

Burnishing and Sealing Encaustic Cement Tiles

To remove the grout and dirt and restore the look of the tiles I opted to use diamond encrusted burnishing pads. Tile Doctor supply a set of these pads comprising of four pads of increasing grits. I started with the coarse 400-grit burnishing pads running it over the floor with a rotary floor machine and lubricated with a small amount of water. Following this I worked my way through the system, applying Medium 800-grit and Fine 1500-grit pads rinsing off the slurry generated in-between and extracting with a wet vacuum.

The last Very Fine, 3000-grit pad is applied dry with only a little water spayed onto the floor using a process we call a “Spray Burnish”. This really refines the look of the tiles and usefully leaves them dry. This process took up the whole morning and the next step would be to seal the tiles, so I went for lunch at this point to give the tiles more time to dry.

Sealing Encaustic Cement Floor Tiles

To be sure they were dry I tested the floor with a damp meter, the readings were fine, and I was satisfied I could go ahead and apply the sealer.

To seal the tiles, I used two coats of Tile Doctor Colour Grow, this is an impregnating sealer that penetrates and occupies the pores of the tile thus prevent dirt from becoming ingrained there. Colour Grow also leaves a matt finish which is ideal for this type of tile.

With the grout and dirt removed and a sealer in place to protect them this floor will be much easier for the customer to keep them clean in future.

Get the Encaustic Look

If you like the look of Encaustic tiles but don’t want the hassle of having to maintain them it’s worth looking at their equivalent in Glazed Porcelain which are very low maintenance. CTD have a Cuban and Havana range which are inspired by the intricate geometric shapes found in Encaustic tiles, both are made from Glazed Porcelain which doesn’t need to be sealed and are therefore very low maintenance. CTD have over 100 tile shops in the UK and you can also buy on-line or order free samples via their website: www.CTDTiles.co.uk

Stone Effect Pre-Cast Concrete Kitchen Flooring Deep Cleaned in Arnside

Posted on October 13, 2017 by TileProf

The stone floor in these pictures are in fact pre-cast concrete tiles created to emulate Limestone flagstones laid in a Kitchen in Arnside. You can’t beat the natural beauty of Limestone but these concrete tiles do give the Kitchen that rustic look the customer sought. The odd thing is, it’s actually less expensive to buy real Limestone these days as Pre-cast concrete is not a cheap product.

Stone Effect Concrete Kitchen Flooring Before Cleaning Arnside

Unfortunately, in this case, the concrete had been smeared with Ivory Grout during installation and the tiler had failed to remove it after grouting and this had dulled the look of the tile. The customer was led to believe by the Tiler that the off-white colour was indeed part of the stone and had put up with it for several years before we were called out.

Cleaning a Damaged Flagstone Tiled Floor

First of all we conducted a test clean to make sure our usual cleaning system would work as well on pre-cast concrete. I was aware that this type of product has a colour dye added to it which does seem to lose colour over the years and also can lose quite a bit of this dye once we start cleaning with strong chemical’s. Not wanting to risk any depreciation in the colouring I opted instead for the application of a set of Tile Doctor Burnishing pads. The pads are encrusted with industrial Diamonds and come in different grits from coarse to fine and I found that not only did the process remove a lot of the of White grout haze left by the tiler but also gave us a good start to the cleaning process without losing any more of the colour Dye.

The customer has specified they were keen for the floor to have more of a sheen finish, so we finished the cleaning with the rest of the Diamond pads finally ending on the super fine pad. We had to do some edging work where the circular pads could not reach but apart from that the pre-cast concrete responded well to this treatment as you will see on the before and after pictures.

Sealing a Flagstone Tiled Floor

The next day we called back to seal the Kitchen floor to protect it from staining, something that is more than likely in a Kitchen. For this we used a couple of coats of Tile Doctor Colour Grow which not only protects by soaking into the pores of the tile but also restores a lot of the colour that had previously been lost.

For aftercare I explained to the customer that sealers do wear off over time and so to get maximum life out of the sealer they should clean the floor with a pH Neutral Cleaner like Tile Doctor Neutral cleaner. It’s designed for cleaning sealed tiled floors and it won’t affect the colour dye or the Sealer we have applied unlike stronger products will eat away at the sealer over time. Additionally, pre-cast concrete like Limestone is Acid Sensitive and as such products like certain types of the Cillit-Bang range cannot be used on a floor like this as it will cause surface damage.

Lustre Restored to Dirty Slate Tiles in Thaxted

Posted on August 6, 2017 by TileProf

[ad_1]

The single most important thing you need to do after having a new natural stone floor installed is to seal the tiles. The sealant acts as a barrier of protection for the stone against ingrained dirt, so without it the floor will become very difficult to keep clean.

This is the exact problem faced by my recent customer, who lives in the town of Thaxted in North Essex. Thaxted is a very historic place with over 1000 years of history and several fantastic medieval houses. The Slate kitchen tiles in the property had not been sealed after installation and, despite Slate being naturally durable and hard wearing, the tiles had quickly become dull and difficult to keep clean.

Despite valiant efforts at a DIY restoration, the customer required our professional assistance with deep cleaning and sealing the tiles to restore them back to their best condition.

Cleaning a Dirty Slate Tiled Floor

To begin the cleaning process, I applied Tile Doctor Remove and Go across the floor and scrubbed it in using a slow speed rotary machine fitted with a scrubbing pad. Remove and Go is a multi-purpose product: it strips away any old sealer, adhesive and paint stains, and draws out ingrained stains and removes heavy soil build-up. The resulting slurry was then removed using a wet-vac machine.

Next, I focused my attention on the dirty grout lines, treating them with a strong solution of Tile Doctor Pro-Clean which was then scrubbed in along the grout line using a stiff brush.

There was still evidence of some grout haze on the stone following installation some years back so the floor was then treated to an acid wash using Tile Doctor Grout Clean-up which is a concentrated phosphoric acid cleaner designed to life grout smears haze (smears).

Once done I pressure washed the floor using a specialised spinning tool which blasts the tiles and grout with water to remove ingrained dirt from the most difficult-to-reach areas in the stone. The water is subsequently vacuumed back into a holding tank in my van without causing any splashing or overspill.

Sealing a Slated Tiled Floor

The customer was keen for the restoration to be finished within the space of a single day, so I installed a few Dri-Pod floor dryers to get the floor dry and ready to be sealed in no time. We typically leave at least 24 hours for these types of floors to dry naturally, but in this scenario the floor dryers were able to remove any excess moisture.

To complete the restoration, I applied four coats of Tile Doctor Seal and Go Extra to the floor to seal it. This a special acrylic-based sealer that protects the stone and allows for moisture vapour transmission. The makes it ideal for situations in which no damp proof membrane has been installed.

The addition of the sealer gave the floor a beautiful lustre – as you can see from the photos below – and will make the floor much easier to keep clean in the future. After months of difficulty, the customer was over the moon that the floor had finally been restored to its peak condition.

Restoring a Riven Slate Patio Suffering from Grout Haze in Wollaston

Posted on June 29, 2017 by TileProf

[ad_1]

This customer, who lives in Wollaston, a small village in Northamptonshire, called me to look at the unfortunate condition of her Riven Slate tiled patio. She had hired a builder to install it, but he had neglected to remove the grout haze which had occurred quickly enough, allowing it to set. He was subsequently unable to remove the haze because he had already sealed over it. This had left it looking very unsightly, as you can see in the photo below.

The customer initially contacted me back in December 2016. At that time, I did explain to the customer that the Winter wouldn’t be an ideal time to restore the patio, and that it would be best to carry out the work in the Spring. However, she was so unhappy with the appearance of the patio and – knowing she had guests coming over for Christmas – wanted something to be done to improve the condition of the tiles as soon as possible.

It was agreed that I would immediately carry out the removal of the old sealer and the grout haze beneath, but leave the re-sealing until the Spring of the following year when the weather was dry. The customer understood that when I returned in the Spring, the patio would require another light clean and brush to prepare it for sealing.

To put the customer’s mind at rest somewhat, I carried out a test clean on one slab of the patio using Tile Doctor impregnating, colour intensifying sealer, known as Colour Grow. This darkened the tile and provided a natural look finish, which was preferred by the customer. I also returned to the property several days later to carry out a water repellency test, but as you can see from the photo below, the rain beat me to it. Thankfully, the repellency test had positive results.

I was then able to begin the cleaning process.

Cleaning and Sealing a Riven Slate Tiled Patio

To begin, I removed the old sealer using a strong mix of Tile Doctor Remove & Go, which is a stripper and cleaner. This product was scrubbed into the tiles with a rotary brush machine. Net, I rinsed away the resulting slurry and soaked up the water with a wet vax machine.

This initial clean exposed the true extent of the grout haze – it was over all every tile! My next course of action was therefore to remove this using Tile Doctor Acid Gel, which is a gel cleaner specially formulated to neutralise grout haze. This was allowed to dwell for a short period before I brushed it in.

Following this, I gave the whole area a second brush with a small amount of water, before using a wet vax machine once again to make sure all cleaning chemicals were removed. I used the customer’s hosepipe to rinse down the entire patio as there was good drainage.

I allowed the tiles to dry out naturally, before waited for a dry day in April this year to return to the property. During this day, I sealed the entire area with Tile Doctor Colour Grow sealer to really deepen the colour in the stone and provide the whole patio long-lasting protection against the elements.
