Grout haze or grout smears as it is often called can be a huge problem when laying tiles. Grout haze is basically grout that has been left to dry on the surface of the tile after installation. It’s a common problem which is exacerbated by the use of quick drying products. Take for example this interesting Wood Effect Ceramic Tile installation at a house in Guildford following installation by a builder. I was a bit slow in following up on the initial enquiry as we had been very busy so by the time, I got in touch I was told they had employed someone else to carry out the work. I apologised for my late response and said to call me if he needed help in the future. Three days later I got a call so we arranged a visit so that I could carry out a test and quote a price. As it turns out the builder had returned and failed to remove the grout haze and so had a rival firm that seemed more interested in selling unnecessary sealer than fixing the problem. I was astonished to see what a state the builder had left his floor. Grout was all over the floor with footprints walked across thresholds and more. I could understand it if there was some grout was missed after installation but not to this level! I carried out a successful test and confirmed to the customer that there was absolutely no need to rip and replace his £2k floor. We agreed a date to resolve the problem and to say he was relieved was an understatement! The builders had used Mapei grout which contains polymers. Polymers offer better flexibility and adhesion, however in order to remove the grout haze we would first need to break down the polymers in the grout first and this is why the rival firm failed. With that in mind, my first action was to apply Tile Doctor Remove and Go to the floor and leave it to dwell for five to ten minutes. I then worked it into the tile using a scrubbing pad fitted to a rotary machine. After washing the soil away with warm water and extracting with a wet vacuum I applied Tile Doctor Grout Clean-up to treat the grout. Grout Clean-up is an acid-based product that breaks down the grout so it can be rinsed away and extracted as before. Afterwards I rinsed the floor with warm water and extracted again to remove any trace of product and neutralise the floor. After removing as much moisture as possible with the wet vacuum I speed dried the tiles with a blower. Ceramic tiles won’t accept a sealer so once the floor had dried the job was finished and it took less than a day. The customer was over the moon with the difference. While his floor was in such a state, he has been unable to bring in new furniture as the serious possibility of removing the tiles was hanging over him. Relieved that the problem was now resolved he kindly left the following review: “I had a floor that had just been laid with very heavy grout haze. I had already had advice from two other professional floor cleaners who had advised me that the floor was irreparable and would need to be pulled up. As soon as I spoke with Rupert, it was clear he was extremely knowledgeable. He asked questions none of the other companies had. By understanding the specific nature of the problem, he was able to solve it by first removing the grout polymers and then applying an acid wash. The floor came up brilliantly. Rupert was the only person I spoke to that could fix this, everyone else told me I needed to replace my floor! Superbly knowledgeable, professional and did an excellent job. Don’t bother speaking to anyone else, just call Rupert! “ Rupert Mcleod West Surrey Tile Doctor
