wet room

[topgun]

HI TO ALL,am new to the forum,i have read a view somewhere,that it is not neccesary to tank the whole wet room,only the area likely to get wet,does anyone have an opinion?Which system is easyest for undertile heating,only i have used the impy system,& was advised to put a self levelling screed over the membrane which adds to the quite high cost of the system to isolate the heating wires from softening the membrane,any thoughts? Regards topgun.

we also use the impey system, we use a lower watt (100 watt) under tile heating, we do not screed the floor just tile over the undertile heating on the membrane (juse make sure you do not damage the wire), we tank the walls in the shower area only and membrane the full floor, we did 5 wetrooms (4 impey & 1 wedi) last year and haven't had any problems

Screeding/skimming over the top of UFH isn't necessary, it just helps give protection to the cabling. Not nice to discover after having done a nice job of laying your tiles and grout that you have caught a cable with the trowel and you have to lift it all up again!

hi,first time in myself.I spoke to impey technical dept on last job about tanking walls in shower area,tiles were 400 x 200 they said not to as tiles and adhesive would be too heavy for membrane.they said no need to go any higher than 75mm up walls.

when tanking a shower area in a wet room you do not use the floor membrane you use a paint on tanking

Different systems use different methods, follow instructions.
Tilesafe show the tanking of walls with membrane, i think Kerdi do too.

Schluters Kerdi mat is just applied to the walls with rapid setting cement based adhesive and can be tiled onto straight away.....if you are using large format tiles then i would leave it to dry abit before commencing giving the adhesive chance to take hold before adding weight to it........
