Recently it seems I am getting called out to an increasing number of new builds to sort out patchy grout issues. The reason why there have been so many issues arising is a bit of a mystery, but I put it down to a combination of things like poor quality grout, rushed installations, wet subfloors and the use of different batches. This recently built house in the village of Darton is a great example and in this case, I suspect two different batches of the same grout had been applied. Darton by the way is a small village in the Borough of Barnsley. Invariably these problems are picked up by the new owner on their snagging list, with the tiler long gone and the builder keen to get their final payment it is always a tricky situation to resolve. I find the best solution is to apply a Tile Doctor Grout Colourant, it’s a much quicker process than removing the old grout and replacing with new. Most new homeowners would not appreciate us ripping up their brand-new rooms and generating lots of dust in the process! Also, by using the Tile Doctor Grout Colourant it adds a barrier of the grout preventing dirt from discolouring it further down the line. Even though the house was brand new, the Porcelain Tiled floor was not looking great. The client was happy for me to go ahead and would take up the bill with the housebuilder. I first pre-treated it with Tile Doctors Grout Colourant Pre-Treatment. This removes any contamination from the grout which might affect the adhesion of the colourant and being an acid, it also etches the surface of the grout to ensure a superior bond with the colourant. The client chose our Light Grey colour which is one of 10 colours we offer. Once the pre-treatment had been applied, scrubbed, rinsed, and vacuumed away the floor was left to dry. Once dry we started applying the colourant, this is done with a small brush (a toothbrush is ideal) carefully scrubbing colourant into each grout joint and wiping off any excess that gets on the tiles before it is able to dry. Once complete the newly coloured grout lines totally transformed the floor and because the grout colorant is epoxy based the grout lines will stay stain free and never get dirty. The porcelain tiles were factory sealed so there is no need to apply a seal to the floor. I recommended the use of Tile Doctor Neutral Tile Cleaner to keep the floor in the best condition. It is pH neutral so is far less harsh on the surface than the everyday household cleaners available. It has a minty fragrance and is mild enough to use daily. They were very happy that the floor now looked as it should have from the start and was the finishing touch to their beautiful new home. Matthew Lovett South Yorkshire Tile Doctor
