    Hi guys in need of some advice please I tiled a bathroom about 1 year Ago and the grout between the wall tiles and tiled floor has cracked all round.i used Mapei anti-mould flexible grout and the house is about 10 years old. Should I just rake out old grout and try again or use something else.thankyou for any advice.

    How wide are the grout lines between tiles?

    The grout lines are about 2 mm,I think maybe they aren't wide enough / correction 1/2 mm to 1 mm

    Why not rake out the grout at the wall/floor join, and replace with silicone?

    I doubt that your wall/floor join is a 2mm gap?

    Your right the grout lines are about 1/2 mm to 1 mm I think they are to small so the only solution is probably to use silicone sealent

    If your grout lines are less than 2mm, as it seems, tghis could well be your problem. As already mentioned, I agree silicone sealant, is the least invasive action to make.

    Actually, what i meant was that i thought that the gap would be larger than 2mm not less.

    I cant claim unmerited credit but all's fine, and i would go with the suggestion above.
