Hi,
I've agreed to do a tiling job for a friend who got fleeced by a couple of cowboys. The job is tiling the walls and floor of a bathroom, the floor is partially covered in 25mm marine ply (supplied by my friend, but only half of the 8' x 4' sheet was used) the cowboys left a small part of the floor covered with two runs of old but solid floorboards and attempted to tile over that (I checked the level of the floor and it seems to be level and without ridges or height discrepancies so i'm thinking of leaving the floorboards there..).
The walls above the bath were taken down (old, rotten plaster board) and hardibacker 12mm was put up badly, it's been screwed down well onto the wall joists but the wall is not level i.e. i put a long piece of wood against it and there are 15mm gaps...
My friend supplied the cowboys with bags of Mapei flexi adhesive and ultra color grout, floor and wall tiles and Mapegum liquid membrane, Mapetape and primer g. The cowboys put down the marine ply and disappeared with the other half and never returned, but worst of all they took all the tiles and the adhesive, my mate is distraught. I said i'd help him out but i'm not sure how to proceed.
He wants the bathroom floor tanked with the Mapegum and tape, but i've never used this stuff before.
my questions are:
1. Do i paint the mapegum straight onto the marine ply and floorboards? (There are only two lengths of floorbaords, the rest is marine ply)
2. How should i go about levelling the hardibacker wall? I believe the wall joists are not level so should i put some kind of spacers behind the HB to level out the wall, or can i apply flexi adhesive to the HB and "skim" the wall with it to make it straight?
3. the floor is solid and noggins have been fixed (no noticeable movement), what is the procedure for tanking application and tiling?
This is how i'm thinking of proceeding:
paint primer g onto ply/floorboards, then apply mapetape to corners and wall joints using Mapegum as "glue", use roller to apply Mapegum liquid tanking with roller onto floorboards/ply, leave to dry and re-apply, tile with flexi adhesive straight onto dried Mapegum.
But i'm not sure if i should skim the wall with flexi adhesive.
What do you guys think?
