Luckily for this client in the village of Docking in Norfolk, the water pipe under her kitchen sink burst the day before she left for a four-week holiday in the USA, so at least she was able to turn the water off at the mains and minimise the damage before leaving for the airport… every cloud, as they say!
On her return she found that the Terracotta tiled flooring had dried out perfectly but unfortunately, the acrylic sealer had suffered badly as the evaporating moisture came up through it and the entire surface of the floor had developed a milky-white bloom. Our client thought that complete replacement of the whole floor, which ran from a large kitchen diner through to a long utility room with separate storage cupboards and a WC would be the only option. Fortunately, before investigating that expensive option she gave Tile Doctor a call in the hope that the floor could be saved.
Deep Cleaning Water Damaged Terracotta Floor Tiles
In order to remove the damaged acrylic sealer, we applied a strong dilution (1:2) of Tile Doctor Pro-Clean mixed with a little Tile Doctor Remove and Go. This was scrubbed in along with a small amount of honing powder using our 17″ rotary machine fitted with a medium nylon brush before being power rinsed and extracted to remove all the chemicals and resulting slurry.
The grout lines, corners and edges where the original sealer had been applied more thickly were then further cleaned by hand with Tile Doctor Nanotech HBU Remover, HBU stands for Heavy Build-Up and this is a useful product for tackling stubborn areas.
The floor was then finished off with very fine honing powder applied with water and a black scrubbing pad before being rinsed and extracted again. Finally, the whole floor was acid washed with Tile Doctor Acid Gel to neutralise all remaining cleaning agents and counter act any efflorescence salts which may appear in the future before being left to dry thoroughly overnight with the assistance of our dehumidifier.
Sealing Terracotta Floor Tiles in Docking
On our return the following day, the floor was thoroughly damp tested and found to have dried extremely well enabling us to start applying the new sealer straight away. The client had specified a muted shine surface for her floor, so we chose to use Tile Doctor Seal and Go.
Terracotta is made from clay which is quite a porous material so seven coats were needed to completely seal the floor. This would provide optimum fluid resistance along with the mid-sheen finish she had requested.
Here’s what the client had to say when we’d finished:
I am delighted with the work carried out. The terracotta tile floor of my kitchen was in a terrible state following a flood and it has been restored to an excellent condition. A very professional and personal service which I am happy to recommend.
