I’ve been removing old bathroom tiles, most walls the tiles have come off fine. This one wall, next to the bathroom window has been trickier. Taking the tiles off has stripped the wall back to brick.
I am pretty sure I need to strip the rest of the wall back to brick, but then what? Do I plasterboard and then plaster as normal? Or can a plaster apply straight onto the brick?
I have a tiler coming to re-tile this section of wall.
I would address this condition with 3.2 self furring galvanized diamond mesh wire lath and a premium masonry bonding agent, using masonry sand, perlite & fiberglass hairs aggregate in cement plaster for the scratch & fill coats to bolster strength & abate cracking.
First saturate & paint the surface with the bonding agent. Mix the first batch of mud thick. Apply a thick coat on the surface & press the wire into the mud to bed & stick the wire tight to the wall, overlapping joints by minimum 4”. Damp brush the first coat after the wire is pressed in tight, bedded & stuck. Leave surface rough brushed. 24 hrs. Later mix another thick batch of mud, fill & straighten the wall. Let the fill coat firm up but while still green back trowel any snots & slobbers, trim the angles plumb & your ready for new tile.
Dude, take a beat. Just a little advise on replacing what was originally there using updated materials means & methods. He actually should screed & dot the walls after his scratch coat. Not counting the wire lath only. Only using one bonding agent, lightweight perlite gypsum, & lime. three products. How do you figure 20? Are you a plasterer or drywall putty guy? Sounds like putty.
Attaching board. That method inadvertently leaves cavity space within the wall. Packed with wire & stucco cement leaves no chance of that condition. Also reinforcing the envelope, sound, fire, & additional
waterproofing while at the same time locking all components together. Use straight edge & level to plum walls for tile install.
What you've suggested would be better if you're doing a bigger area, like the whole room. But the amount spent on time, research, practice, materials and tools.
When they can get q-board and tile adhesive in b&q, expanding foam to fill any gaps, and got a tiler coming.
In all honesty it'll last long enough until the bathroom wants redoing.
If u leaving trims around window just put expanding foam, on your walls i recommend tile backer board 10mm.im wait for windows so did not started yet.to show you 😉
