Dot and Dabbing plasterboard

[poynton phil]

I'm going to dot and dab plasterboard onto brickwork tomorrow, not done any before, so i'm just wondering are there any do's and donts. Any advice will be appreciated.

Are they to external walls or internal

Flour and water is not an appropriate wall board adhesive......

best of luck with it.

internal whitebeam, only about 3 msq around a door

make sure your bricks are dust free Phil, I normally give them a coat of SBR 3:1, dont scrimp on the adhesive

Cheers douge, i did give the a good brushing, but didn't think about sbr. i was thing pva

I think in this instance, pva would be ok, I just use SBR cos I don't use pva when tiling, so I never have it in my van but always have SBR

Uneven walls can be straightened by first surveying the wall with a combination of levels and string to identify low and high points of the wall. Low points will require deeper dots and dabs, low points will require shallower dots and dabs.

Once the dots and dabs have been applied, offer the board up to the all. Allow the adhesive to grab but do not press home.
Use a combination of levels and straight edges to now check that the board has no undulations both horizontally and vertically. Also use a level to check that the board is vertical. Using a known straight edge, the manufactured edge of a piece of plasterboard is ideal and can be cut to any size that is needed. Tap the board in a place where it will correct any deviations from the desired line. Do not tap with your level as it will become damaged.
Once the board is level, tap it firmly home for final positioning.
