They will say all chipboard joints have to be glued (they never are!)
Chipboard will have to be screwed every 300 mm into joists (most joists are 400/450mm apart)
If using moisture resistant chipboard you will also have to sand the top surface as...
weber set rapid plus and weber ad250 can be used onto chipboard as a 2 part adhesive.
However I would still overboard with hardibacker board personally and then use a SPF adhesive. I'd stay clear of tiling directly onto chipboard
Sounds like a complete cowboy job to me.
I would use a self levelling compound rather than screeding the floor. If you screed the floor you would need to wait for it to dry which is normally about 3 weeks unless you use a green screed adhesive then it would be less. With a levelling compound...
Hope you enjoyed the vino tinto Richard?
I wouldn't risk tiling direct onto floorboards.
I would personally use 6mm hardibacker on top of the floorboards. Then use a good SPF adhesive.
Your welcome.
just look for a powdered cement based adhesive.
look for a c2 classification adhesive if possible which is the european standards. Most good adhesive companies have this on the packaging.
Best practice would be to remove tiles.
You don't know how well the tiles have been stuck down originally.
Then I would use a self levelling compound to smooth over. Then you will have a nice flat surface to tile onto.
First of all I would sort all the tiles out into thickness of tile. For example put all the thickest ones together and the thinest ones together. This will make it easier when you come to tiling. Start with the thickest ones as then you'll be able bed the thinner ones out.
I would certainly...
I wouldn't use a ready mixed adhesive in this situation as the adhesive will take to long to dry.
I would personally use a powdered adhesive like weber set plus or mapei P9. They don't require any additives for tile on tile.
Yes tank the PB in wet areas. MR PB can still break down in water.
or use 12mm Hardibacker on the walls which is fully water resisitant but you will still need to tank edges and joints.
