What is 'Dot and Dab' and how is it done?
I have heard this on many DIY programs and think it may be suitable for appling plasterboard to my brick out-buildings. What adhesive/mixture do I need and how long before I can plaster, paint and drill etc?
Answers:
The first answer is correct ,but i wouldn't recommend it for out buildings as it doesn't give a barrier to damp,in fact the adhesive bridges the gap.It is better to line the wall with a suitable membrane and use timber or metal framing.Your timber frame should sit on a dpc as well.
Basically, you "dot & dab" the boards in place with dry-lining adhesive
(available from "proper" builders merchants). This involves placing 5 or
6 "dollops" of adhesive on the wall, then placing the board on it and
rapidly moving it back and forth to spread the adhesive and get it
plumb/straight.
You then use nailable plugs, which are basically a nail covered with a
plastic plug (similar to a rawl plug). Drill a hole right through into
the brickwork and hammer the plugs into place. Use sufficient to ensure
the board is solid, and more round the edges. (I would advise more than
normal, as you intend to tile).
By the way, if your existing tiles are solid, I would leave them in
place, as the nailable plugs will go right through them anyway, so you
will be securing to the brickwork.
Tiling onto plasterboard is fine. Just do it as normal
Dot and Dab also known as dry lining is a way to stick plasterboards to brick walls and reduces drying out times that plaster needs the plaster you need to stick them to the walls is called Bonding Compound if you wanted to plaster it you could plaster it the next day when the dabs on the back of the boards are set.Once the plaster has dried out completely then you can paint you will know this by the colour change from dark to light and then you are ready to drill but be aware you will have a cavity between the board and the wall so you will need to use plasterboard plugs hope this help good luck
Dot and dab is process which you stick plasterboard to masonary walls using dabs of adhesive. the adhesive used is drywall adhesive and you can generally start plastering/painting the next day. however if you are considering using this method on brick out buildings which only have single skin wall (1 layer of brick between inside and outside) you will have problems with moisture transfering from outside. leaving damp marks on wall at every dab of adhesive, if this is the case best opt for stud partion.
dot and dab is a means of sticking a plasterboard direct to internal walls instead of having a 2 coat plaster finish its a cheap way to plaster new houses you just mix your plasterboard adhesive to a thickish paste dab it on the grey side of the board at 8"centres once dabbed in dots all over you push it to the wall using a long straight edge tapping against the board use a level to check if its plum. check along straight edge make sure theres no hollows this needs to be longer than the board. you dont have long with adhesive it sets pretty quick you can skim it day after.
