I was asked to look at a Terracotta tiled kitchen floor that had just be fitted at a house in Kidlington, it seems the tiles were sticky and patchy and basically looked a bit of a mess. The home owner phoned me on Thursday sounding really upset and as I’m based in the general area I was able to look at the floor later that day.
On inspection I could see that the recently applied sealer had not taken to the floor probably as it was not been allowed to dry properly before sealing. We didn’t know what had been applied on the floor so I did a test on a couple of tiles to see which products would work best to strip the sealer off and then booked the job in for the following Saturday.
Cleaning Terracotta Tile
I placed my dust sheets down were needed and then I started on the floor by wetting it with a strong dilution of Tile Doctor Pro-clean, this product is quite versatile and being alkaline is safe to use on tile, stone and grout. The floor was then scrubbed using a rotary machine fitted with a black scrubbing pad to agitate and then rinsed down with clean water which was then removed using a wet vacuum and the floor left to dry. This process was repeated until I was satisfied that all the sealer was off and then give the Terracotta a thorough and final rinse to neutralise the floor and make sure there was no chemicals were left on the tile, again a wet vacuum was used to remove the water and I also asked the customer to leave the front and back windows open so the air flow would help dry the floor quicker.
Sealing Terracotta Tile
After a couple of hours I tested the floor with a Damp Meter to confirm the floor had dried and began to seal the tiles using Tile Doctor Seal and Go sealer which is an ideal sealer for Terracotta and also provides the satin finish the customer wanted.
Tilers may know how to tile but I wouldn’t trust them to seal a floor, let them stick to what they are good at and leave the sealing to us.
