Been to look at a job which includes 2 wet floors. When i asked what formers he using he said i'm not, just want you to form the slope using tiles, i have never heard of doing it this way, so could do with some advice on it. Any help with this will be greatly appreciated.

hi whats the sub and has it been recessed

Its a 18mm ply, to be over boarded with cement board, and shower area will have a 6mm recess

not much fall whats your standards require take it all cement sheet

What size recess would be best jay, and yes its all cement board

This method is asking for trouble the deflection is going to cause problems in your wet area............


.

cut the backer board and screw fix and bond them to the 18mm ply with solid bed of Keraquick incorporating latex plus to form the "fall.
Tank with Mapegum WPS OR Mapelastic. Tile with Keraquick and latex plus. Grout joints with Ultracolor Plus and fill internal vertical corners and junctions of walls and floor with Mapesil AC colour to match grout.
Leave it for a fortnight before leaping in!!

Keraquick can only be used to 6mm bed...you need more than a 6mm fall to get sufficent drainage in a wetroom..IMHO dock..

Building up tiles to form falls is very outdated and not a fail safe method...

I recommend the use of a preformed former...better to be safe than sorry..

Thanks guys, i'll pass this info on to my customer, hopefully he will take it in and give tony a call for a couple of formers.
