Hi

First time posting, please bear with me as I am definately an amateur!

I am converting a downstairs room in my house to a shower room. The old wooden floor was rotten so has been replaced with a breathable limecrete floor (this avoids the problem with introducing a concrete subfloor which pushes any rising damp into the walls) I would like to tile with terracotta tiles, but need a laying/sealing method that will allow moisture to permeate through the tiles and https://www.tilersforums.com/forums/tile-adhesive/ - does anyone know of any products/methods for accomplishing this?

I also want to tile the walls, but again as they do not have a damproof course there is a small amount of rising damp. A building regs officer suggested a product called Olroyd P which is fixed to the wall and then rendered over before tile - has anyone used this product and if so does it work? Are there any other products/methods that people have used that would allow me to tile onto a slightly damp wall?

Hi Philstor and welcome to the forum!

That's a really interesting question you posted there, hence the thankyou, sorry I can't help you with that but before long the cavallery will arrive and tell you all about it, I'm sure. There are enough waterproofing options out there, but as to the 'but need a laying/sealing method that will allow moisture to permeate through the tiles and https://www.tilersforums.com/forums/tile-adhesive/ - does anyone know of any products/methods for accomplishing this?', well, I'm lost. Think mildew etc... quite a horrible thought.

Good luck to you and your project anyhow. :thumbsup:

Hi phil.....

Schluter do a membrane that will be perfect for your project...... Schlüter-DITRA - Schlüter-Systems

You will need a slow setting flexible https://www.tilersforums.com/forums/tile-adhesive/ for sticking this membrane onto the walls and floor.....With damp still present within the substrates then a slow set https://www.tilersforums.com/forums/tile-adhesive/ will hold better as fast setting https://www.tilersforums.com/forums/tile-adhesive/ will be hindered by the moisture....then the ditra membrane will allow the walls and floor to breathe and the moisture will vapourise within the dovetail of the matting.....

You can then tile onto the membrane with a standard set or rapid set cement based https://www.tilersforums.com/forums/tile-adhesive/....

Suitable https://www.tilersforums.com/forums/tile-adhesive/ for sticking the membrane are Mapei keraflex maxi or ultraflex mono...or if you can only get BAL then.. green screed https://www.tilersforums.com/forums/tile-adhesive/ or BAl single part flex.

You will need to check with the https://www.tilersforums.com/forums/tile-adhesive/ tech line for suitable primers for lime crete screeds..:thumbsup:

Many thanks for the replies everyone - certainly some interesting products suggested. I'll chase up some suppliers and get quotes this week.

when using limecrete philstor, obviously wear gloves, and apply some vaseline to your face, it will act as a barrier cream, lime burns can be very nasty!:thumbsup:
