Earlier this summer I was called out to this job in the garden of a house in the city of Ely to inspect a freshly laid porcelain tiled patio with grout haze issues. The builder who had installed the patio hadn’t removed all the grout from the textured surface of the tile before it had dried. This was probably due to the hot weather which reduces drying times and has caught many tilers out. Multiple repeat visits by the builder trying followed who spent countless hours trying to remove the grout haze, unfortunately due to the textured surface of the tile he was unable to remove it and the patio was left looking awful. Like the builder we are increasingly finding modern grouts, which although more durable, are very difficult to remove. Fortunately belonging to the Tile Doctor network, I had already been made aware of this problem and was able to offer a solution. I arranged to pay the property a visit to demonstrate a potential solution and quote for resolving the issues. Even though the grout haze was indeed difficult to remove it wasn’t impossible if you know how. The demonstration came out well and relieved that they had finally found a solution to the problem booked me in to get the work carried out. On my return I started with the application of a strong dilution of Tile Doctor Grout Clean-Up. This product is ideal for removing grout haze or smears as they often referred to; however, being acidic we don’t recommend it for use on every surface so if your using it yourself do check the label first. I left it to soak in for ten minutes before being agitated with a black scrubbing pad fitted to a rotary buffer The weather was good, so it wasn’t a problem working outside and once all the grout smears were removed, I finished off by giving the whole patio a high-pressure rinse. I use a van mounted rinse/extraction system for this that applies warm water at high pressure onto the patio to dislodge dirt and then extracts the waste into a separate tank in the vehicle. It was an expensive investment but makes light work of jobs like this. It took around four to five cleans to complete the job, by the late afternoon the grout haze was gone, and the porcelain patio looked completely transformed. It was quite a warm day, so the patio soon dried allowing my client to use it later that day. I should mention that this variety of Porcelain tiles were not the micro porous type and therefore did not need to be sealed. Relieved the problem was finally resolved and happy with the result my client left the following feedback: Amazing service, they were able to provide us with a quote and demo before we agreed to work. We are so happy with the results we have as our patio slabs looked ruined to the eye but the Tile Doctor managed to get them looking brand new. Tom Conlon Cambridge Tile Doctor
