Dot and dab board onto very uneven wall.

[Gad-Westy]

Not sure how well the photo will show this but I need to board over a particularly uneven brick wall.

Was hoping to use this foam type stuff that I've used before but maybe there are better alternatives.

Anyway, my questions:

1. Any limit on how big a gap I can bridge adhesive over?
2. Best way of getting the board squared up and keeping it there while adhesive cures?
3. Should I be using a different type of adhesive?

Pic will follow in a min.

If you’ve got the space you can put squares of plaster board on the wall with driwall adhesive
Say 6”x6”

Get these really level if you can
Then dot and dab again a whole board onto the squares

If your worried about the squares sticking to the surface you can plug and screw with washers

If it’s really unlevel you can do squares on squares
I’ve done up to 100mm in isolated areas before with no issue

Sorry, I hadn't spotted your reply. Seems like a good good plan thank you.

Unfortunately I have a rotten floor to repair first but I'll follow your suggestion once I start on the walls.

If that's the wall you are boarding wouldn't it be easier to remove the bit of plaster that's still sticking to the wall so it would be more one level? Either that or slap on a rough layer of undercoat on the low section - anyone could get it better than it is now as it doesn't need to be perfect.

The plaster is coming off but there is also a recess where there is still a tile and the top part of the wall protrudes a lot more than the bottom. Not clear on pic.
