Details below of a restorative clean and seal that I recently completed on a Quarry tiled hallway at a house in the small village of Riseley, North Bedfordshire.
The floor was a mix of fantastic black and red tiles; however, it had lost its character after a long period without professional maintenance. My client commissioned me to strip off the old sealer from the floor and replace it, but not before providing a thorough clean, including tackling some adhesive staining and inherent grout haze.
Cleaning a Quarry tiled floor
The first task involved mixing our high alkaline cleaner, known as Tile Doctor Pro-Clean, with water to form a strong solution. The solution was applied to the tiled floor and left to dwell for a short period. This dwelling time allows for the Pro-Clean to seep into the stone to get underneath the ingrained dirt and lift it out. Pro-Clean also contains stripping properties, and thus helped to break down the old (and now ineffectual) sealer.
After completing this initial clean I rinsed the floor using a standard mop and bucket method. With the old sealer removed, it became evident that there was also plaster residue marking the tiles, as well as inherent grout haze on the surface of the tile probably from the original installation. To tack these problems I used Tile Doctor Grout Clean-Up, which is an acid-based cleaner that dissolves the adhesive and the grout. Being an acid you have to be careful and ensure the floor is rinsed thoroughly after use and if you’re considering using this product yourself read the label and make sure you use the right protective equipment.
Sealing a Quarry tiled floor
After the floor was thoroughly rinsed with water it was dried as much as possible using a wet vacuum which literally sucks the water off the floor. The floor was then left to dry for four days, with the help of several air movers. By the time I returned to the house, the floor was completely dry and ready to take the seal.
I opted to use a combination of sealers, including one coat of our colour enhancing, impregnating sealer, known as Colour Grow, followed by three coats of Tile Doctor Seal & Go to provide a truly robust and aesthetically pleasing surface seal.
You do right to make sure the floor is completely dry before sealing, sealing a damp floor can lead to unexpected results.
