First job with porcelain - advice please

[sammy j]

Hi all

I'm about to start my first job on my own later this week, a small bathroom, about 8m2 of wallspace and 3m2 of floor, with porcelain tiles, 300x300s on floor and 150x200s on wall. Its on first floor and so floor is floorboards which currently has very thin board (5mm?) tacked down on it, one of walls is plaster and others are mixture of plasterboard and timber.

Was just wondering if anyone had any general advice or if theres anything I should be aware of that I might not be (particularly in terms of preparation). Powerspec recommends tanking and then using Single Part Flexible (on walls), and Gold Star on floor, so thats what I was going to do.

Any thoughts much appreciated...

sounds like may be tricky using a rapid set s.p.f on walls due to drying times, BAL ctf3 is good for porcelain. With the right primer, and allows for extra work time. Wouldn't use gold star on the floor, take up that 5mm stuff. If boards are sound use two part flex, If boards have excessive movement, creaking etc use 15-20mm wbp grade ply, screwed to 6 inch centres, with single part flex, remember to prime the edges of the ply and allow 15mm around edge of room for expansion. Use proper primer, not pva, check all walls are solid enough, and you should be fine.

Bal spf is not rapid setting..it takes 16 hrs to set......bal CTF3 is not suitable for porcelain unless AD1 admix is used in conjuction with it...... ....
What ever it is tacked on the floor needs to come up( sounds like hardboard).. and you can either ply it like m,w,tiling says or you could even use something like hardi backer if the heights are an issue.......You can use the SPF on the walls and floor and long as the right prep work is done..........good luck..

If the floor is sound and you have height issues, you could use ditra.

Cheers for that guys, so if I'm taking up the thin boards and putting ply down, and using SPF for walls and floor, is it necessary to use a primer? And tanking? Its only a bath splashback, no shower etc...

 

[DHTiling]

No need to tank really for bath splash back.........BAL only recommend you prime the back and edges of ply and not the face side............. ...always check wot each individual supplier recommends.....
