|
|
|
Hi all
Just renovated my bathroom but big problem with floor grouting.
It's constantly breaking up.
Floor is level, tiles are all OK, used Unibond waterproof coloured grout but it's doing my head in.
Used the same grouting everywhere else and it's fine.
Any one got any ideas????  |

| Sounds like the floor is moving. What have you put under the tiles ? |

Thanks for fast response
Screwed 8mm MDF to floor boards to give flat even surface.
UPV'd as directed by Unibond grout. |

Think that could be your main problem |

Yeah, a classic mess up, not only did you use the worst type of board imaginable, it's also too thin and you primed it with the wrong product.
Rip it all out and do it properly, if you need help, ask. |
