New boy here. In the later stages of a big refurb and extension project which will be my house! My Builder has a few bits left, but tiling and deco is down to me. Difficult with a full time job. Keen and careful, but new to tiling. Been on a 1 week tiling course as an intro, and have good basic tools. Very grateful for any help from the experienced please!
Working on tiling 2 bathrooms and a cloakroom, so I can get them fitted. Total 30m2 tiles for 2 floors, walls, boxing, traps, mosaics, showerbath recess, walk in shower walls (whose idea was this??). So no pressure. Already laid both floors 330 x 330 porcelains with Bal Rapidset flexi over ply on chipboard floors (not grouted yet) plus 50 x 50 mosaics onto ply boxing using Ardex D30 in 1 bathroom for inset basin and back to wall WC, with traps and 330 for tops. Looks smashing.
Problem is with showerbath recess and walk in shower recess walls, which are skimmed over either plasterboard stud or plastered block (4 months dry). Using a combination of same porcelain 330 square tiles and 25 x 25 mosaic on sheets. Was sold Ardex D-30 adhesive supposed to work on plaster, unprimed. I cleaned down well first but low areas I shallow-filled with D30 just cracked and fell off when dry. Then I well wire brushed whole test area and filled - same prob. So then I primed wall with Ardex Ardion 51. D30 sticks well to it, but running a scraper under when dry, it comes off easily with primer. Not confident it will hold a tile weight, let alone a wall!
Due to mix of wall types and cut/plumbed in bath and tray, don't want to rip walls out and replace with tile backer, but is there likely something odd in my plaster? Should I tank it and will tanking stick? Or is it the addy? Should I be using a cement based powder like the floor adhesive I was using? Am I going mad???
Cheers,
