Dot and Dab

[sweeneyuk]

I am renovating my 1900 terraced house & would be grateful for some expert advise.

The origanal plaster was well shot & falling away in lumps exposing the brickwork on the front external wall.

this is a solid wall with my front door & 1 window.

I want to dot & dab plaster board to ease decoration but have a few questions for all you experts.

1. when using tapered edge plasterboard how to you join & fill the non tapered edge if you only plan to tape & fill the tapered edges?
I see the american/canadian diy shows never plaster their drywall, just fill the joins & screwholes.

2. Will i need to use a foil backed board as its an external solid wall?
no damp issues but have some exposed brickwork.

3. as the plaster has been patched in places in the past i have a very uneven surface to work off. the are areas with render, plaster & some with bare brick. can i just add extra adhesive when dotting & dabbing to bring it all level?

If i was to use insulation backed board like celotex pl3000 will the insulation react with the pvc insulation around electric cables?
Should they just be capped?

Also just a word of warning, steer well clear of crystal double glazing, long story for another post.

Any help appreciated.

sweeneyuk,
Stick with real plastering pref lime based, sealing the wall with plasterboard will trap moisture and lead to damp problems.
