Removing Grout Haze from Slate Tile Flooring

You may remember a previous Limestone floor job we did for a Mrs Schwartz from Stourbridge, well true to her word she invited us back to clean and seal the slate tile flooring in her hallway which had been left with grout smears (aka grout haze) on the surface after tiling. Grout smears can be removed however if the floor is sealed it’s necessary to remove the sealer first.

Cleaning Grout Haze off Slate Tile Flooring

To remove the sealer and clean off the grout smears we used a 50/50 mix of Tile Doctor Remove and Go combined with Nanotech Ultra-Clean for added effect, the solution was left to dwell on the surface of the slate for 15 minutes to break down the polymers in the grout. The next step was to turn on a high pressure spinner tool which is a very effective cleaning tool on its own; the water from the spinner tool also washes away any chemicals and neutralises the floor ready for sealing.

Sealing Slate Tiles

We speed dried the slate tile flooring using a number of industrial fans and applied three coats of Tile Doctor Seal and Go which offers a good combination of stain resistance with a low sheen finish that brings out the natural colours in the slate.

Limestone Floor Tiles Polished to a deep shine

Great photograph below of a Limestone floor in the kitchen of a house near Coventry. The Limestone had lost it’s shine after the application of a surface sealing “Clean and Shine” type product; the problem was akin to the application of a wax finish which in turn had been contaminated with cleaning product and soil underneath. The grout line has also become heavily soiled through everyday use.

Cleaning Limestone Floor Tile

First the Limestone tiled floor was dry vacuumed to remove loose grit; we also took to opportunity to remove the kitchen unit kick boards. This was followed by a good clean with a 1:5 mix of Tile Doctor Pro-Clean which was left to dwell for 15 minutes before the application of a stiff grout brush on on the grout lines followed by the use of a slow speed buffing machine to break up the surface wax on the tile. The whole are was rinsed down using high pressure clean water via a spinner tool which removed any left over dirt from the grout lines.

The next step was to use the diamond encrusted burnishing pads system to prepare and condition the limestone floor tiles prior to polishing.

Adding that deep shine to Limestone Tiled Floors

We then applied Tile Doctor Shine Powder using a White buffing pad to provide that extra deep shine you can see in the photograph, it also provides and tough durable finish.
