The grout in my bathroom is going black due to mould. I do open windows, but not always possible as always in a rush for work. There is a manually operated fan. It was tiled around 2011.
I have used two different products in different places. Mapei (B&Q) and Dunlop grout (from Selco) which has Microban. Both have failed over time. I also used TopTiles grout protector, that didn 't work either but when I complained, I was told it was my fault for using bleach (some bathroom cleaning products may contain an element of it). Even the silicone, has gone black (the manufacturer said my fault for not cleaning it!). I heard some trademen, say trims around bathtubs not a good idea....
Is there any solution?.
I need to break a bathroom a tiled bathroom area to fix a problem and then re-tile again. So want to know what I can do better next time.
