We were consulted on this Terracotta Tiled floor because the owner complained that whenever she cleaned and sealed them they always got dirty quickly. I asked how many coats of seal was used on the floor and as it turns out only two coats were used because that was the instructions on the bottle. I suspect the bottle hadn’t listed Terracotta specifically and I informed the owner that with this type of floor the minimum amount of coats would be seven, she was very surprised by this but the fact is Terracotta is very porous.
Cleaning Terracotta Tile
I started the job using a strong solution of Tile Doctor Pro-Clean, which is a heavy duty alkaline product ideal for cleaning tiles, scrubbed in with a black pad fitted to a rotary machine. I had to repeat this about five times and also used a steamer to clean out the grout lines and any bits left on the tiles, once this was done I thoroughly rinsed the floor to remove any remaining chemical and left it to dry overnight.
Sealing Terracotta Tile
I left the floor to dry overnight and the next day came back to do the sealing. There were a couple of spots that needed further attention which were tackled using the steamer which has the added advantage to neutralising the floor and evaporating leaving the floor dry again. Tile Doctor Seal and Go was used to seal the floor, it’s a water based sealer so it doesn’t give off an odour when it’s drying and also offers durable stain protection together with a low sheen finish. In the end the floor actually took nine coats of sealer before it was fully sealed, which naturally took a long time to apply as you have to wait for it to dry before applying the next coat.
The lady was extremely happy and said it turned out exactly as she had always wanted it to.
