dot and dab wall sealing

[vibetime]

hi , can you just dot and dab straight onto bricks and low suction blockwork ? i have seen plasterers do it but looking online its a mixed bag of ideas ? also why are the boards not put direct on the floor ? is it for rising damp ?
cheers

You can dot'n'dab straight on to most flattish walls, that include low suction.
If the wall was a high suction wall, you could consider applying PVA to the walls but the dry-wall adhesive is designed to take care of this.
Yes it is standard procedure the leave a slight gap of about 25mm at the bottom of the board, this will stop any contact dampness/moisture on the floor rising through the board and effecting the gypsum within it.
