How to Remove Grout Smears from Encaustic Cement Floor Tiles

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   Source: Encaustic Cement Tile Cleaning and Sealing Service in Chipping Norton, Oxfordshire

Removing Old Grout Smears from Concrete Tiles is South Cumbria

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.


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.
