bathroom/wet room floor
After a supposed tradesman who was recommended to me replaced and re-grouted some tiles on my wetroom and also heated bathroom floor, some of the grout he used cracked and came out after a few days, so i complained & got my money back. Disenchanted i checked out some youtube video's and decided to tackle it myself as im reasonably handy at DIY, and chose Ultra flex for the grouting, as i dont think the tradesman used proper flexible grout, as one or two of the tiles above the heated floor had slight movement and i didnt want to take them all up and re-lay and risk damaging the heating. I chose Ultra flex because of the good reviews and im glad i did, it mixes well, is bright white and a month later none of the re-grouting i did has cracked or shown any problems so i'm well happy and would recommend it

Said flexible but cracked
Mixed this as per instructions but still cracked in some areas. So can't give full marks or recommend. Shame as some parts were fab.
