How to use a Pin Gun to remove Self-Levelling Compound from a Quarry Tiled Floor

We were contacted by a client from Formby asking for advice on how to remove a thick layer of floor leveller from her Quarry tiled floor. I suspect at some point in the past a previous owner had decided to cover the tiles with lino and a cement-based levelling compound was applied to level the floor first. My client had tried to remove it herself but found it very hard going and after realising she had quite a project on her hands decided to call us instead and see if we could help with the restoration.

 

I worked out a quote for the client which would include removing the self-levelling compound, cleaning up the tiles and then sealing them to improve its appearance and protect it going forward. The quote was accepted, and a date agreed for the restoration to be completed which would take two days.

Cleaning and restoring a Stone Tile Kitchen Floor

We have a variety of tools that we can use for removing cement but in this case, I decided to use an air operated pin gun. The head of the gun has long pins of different length which are fired at the floor gently chipping away at the floor compound, this made short work of breaking up the cement so it could be swept away. A lot easier than the method the client had previously tried.

With the floor clear of cement, it was given an acid wash with Tile Doctor Acid Gel scrubbed in with a buffing machine fitted with a black pad. The acidic formula cleans up the stone of old cement including fine particles of dust. Afterwards the gel was rinsed off the floor with water and extracted with a wet vacuum.

Sealing a Stone Tiled Kitchen Floor

We let the floor dry out overnight and returned the next morning to apply the sealer. For the best results, the stone needs to be dry so before sealing I always take several moisture readings with a damp meter to make sure. The results were good so the first of what would be three coats of sealer were applied to the floor. I used Tile Doctor Colour Grow for sealing, it is an impregnating sealer that works by occupying the pores in the store thereby protecting it from within, it also brings out the colour in the stone.

Once done the floor looked great, the old self-levelling compound was gone and the rich colours in the tile had been restored. In fact is was only when finished did we realise these were in fact Baked Clay Quarry Tiles, minerals are added during manufacturing to give then colour, although 95% clay they are very tough like stone. The client was over the moon with the outcome, the floor had been restored to its’ former glory.

 

For aftercare I recommended the use of Tile Doctor Neutral Tile Cleaner to keep the floor in good condition. It is pH neutral so will ensure the newly applied sealer is not compromised and the floor will continue to look good for a long while to come.
