Hey guys, Hope everyone is ok today.
Reason for my post is i am having a few issues with my kitchen floor tiles.
I had an uneven floor in my kitchen so put a concrete layer on it about 15mm then tiled over it.
90% of the fllor is spot on but in one area the concrete starting crumbling and the tiles wont stick to it.
I removed the concreate and redid it. 4-1 mix with cement and builder sand and some waterproofer/plasticiser in the water mixed to correct amount. Once dry i added some own brand b and q tile adhesive to the floor and stuck on my tiles. Next day the tile glue was rock hard around the edges but the tiles had not stuck. They come away without any force.
Another thing i have noticed is the concrete is not rock hard. Its sort of dusty and if i scrap it with my trowel i can make deep scores in it and the concrete just goes to dust.
Any ideas what i have messed up on would be welcome.
Thanks for reading all.
Cheers
Gav
