Dot and Dab Plasterboard

[ruairi mac]

Hi Folks,

Just have a question I was hoping someone could help me out on. I've read a few posts that have mentioned dot and dab plaster boarding to straighten walls. This is something I have never seen being done or even mentioned on any job or site I've been on.

I have seen it done in some of those DIY shows before but as far as I remember the boards were only ever skimmed over and not tiled on. It seems to be common practice with some of you guys how ever as I said it's something I haven't come across.

Could some one give me a few pointers on how it's done? prep before hand, when not to use this method etc. I'm sure there is a video on youtube some where but then again I've seen some of the How To Tile videos on there. LOL

To start with any loose material needs to be removed from the wall and preferably back to the brick/block wall. If you do decide to overboard an existing wall then a purpose made sealant Gyproc Sealant should be used rather than dabs of dri wall adhesive.

You might want to check BG's website as well Literature

This might sound stupid but if you go to the trouble of stripping a wall right back to block work would it not be best to just scratch a coat of sand and cement on to it? Is it a time issue thing?

I was going to suggest looking at YouTube, but then remembered there's a lot of Tommy Walsh clips on that site!? :yikes:

I find it's quicker to board out, if you sand/cement then a drying time is required for the render.

A scratch coat is a first coat and then a second coat of render will be required.

Cheers Whitebeam, I thought as much.

Thanks DGJ.
