Slate bathroom : stains, sealing and cracked grouting.

[Mcarey]

Hi,
We've just bought a house, and have a ten month old demanding baby 🙂. The previous owners had a flood and the bathroom was redone. It has a slate floor and shower( slate walls). The grouting is cracked in the shower, and it leaks through the kitchen ceiling when running for too long- is this due to the cracked grout, or should there be something behind the tiles to stop this? The slate doesn't appear to be sealed and the bathroom now has lots of white marks I can't get rid of, what should I do? Any help massively appreciated. Anything that takes a long time is somewhat hard due to my little one, and I feel a bit stuck.

sorry true tiling perhaps my reply wasnt very clear, a movement joint must allow movement if you leave a gap between any 2 surfaces and its is unfilled this is a movement joint allowing the 2 surfaces to move independantly of each other that is the important part of any movement joint the GAP or space between them, ideally no filler at all should be used but elastic materials are used to protect the edge of the tiles and to stop a dirt build up in the joint ,the filling of the gap can be any material which allows movement ,solid materials would stop the movement and it would be a movement joint any longer

I getting confused true tiling as first off you were talking about movement joints on supermarket floors and then edited your reply, you are being very naive if you believe that Silicon joints last forever ,in a wet room situation all the waterproofing is done behind the tiles and does not rely on the Silicon joint to make a wet room waterproof

If we are talking floors, then it appears your knowledge is limited: what you have just said needs education. You are using GAP and space/movement joints to your advantageous argument. You lost it. Read up!

Sounds like you need to go on a 5 day course Gary, I hope you've not tried a wet room yet.

I am not that confident yet Peter the last few I did didnt turn out that well

Must have been a real doozy that 5 day course Gary, you do a mean wet room, I might PM you and get the address of the place, I might enroll on that, I like you am very keen to learn this tiling lark. Good job there are some very experienced people on this site.
