Just wondering if anyone has bothered to plasterboard the walls in a solid block home? Is there any value in it other then creating a nice smooth finish with a more modern feel?
Also if you have a rendered surface already but it has that gritty unsmooth feel to it, is there anyway to hard sand this back to remove the fines and then paint over it?
Thanks very much
1 – yes, face blockwork is a cheap & practical finish but render/plasterboard is more upmarket. When was the last time you stayed in a hotel with face block walls (& what did it cost you) – not as much as the Hilton.
2 – if the wall has not been painted previously, you can rub the wall back with a timber block otherwise you may have to use a gritty sandpaper.
thanks for that.
The house is solidblock but has been redered and painted inside already but the finish just seems to be slightly rough. Would you just get an orbital sander with a course grade sand paper and go over it, clean it and then repaint?
What kind of dollars are you looking at to plasterboard over this render through an entire house – modest size say 110 sq. living space. I have no idea how much plasterboard costs atm?
would it just be a matter of plasterboard with a bostik style glue and then regular plaster finishing?Thanks for any info provided,
Mate if you want to plasterboard over a blockwork wall there are a couple of options that are open to you. You can either just stick the plasterboard to the blockwork using masonary adhesive (which is like a cornice cement), or batten out your walls with metal battens and then apply the plasterboard to the wall battens. When using either methods just be aware of the affect it will make to your door openings etc, as the extra width of the metal batten/masonary adhesive and plasterboard will bring the finished surface past your existing finished wall……if you know what l mean.
Personally we have used masonary adhesive to stick plasterboad to blockwork and it’s worked like a charm. Oh yeah, one thing you must do when applying the adhesive to your blockwork, make sure you have rub the section back where you are applying the adhesive blobs. If you don’t, the stuff won’t stick properly.
Hope this helps.
thanks uncle knackers,
i know this is a huge guestimate, but doing an entire house what kind of dollars are we looking at if labour is done by myself. 3 bed, 1 bath, normal say around 110 sq.m living total. any indication would be much appreciated. The render is quite gritty still if you know what i mean, so if you look at it from a few metres away u can see quite a rough surface thats painted. Is there anyway of just getting a orb sander and going to town on it and getting it really smooth then put a seal on it and paint over.Mate, if you are doing the work yourself, the cost of the plasterboard alone is around the 5 to 6 dollar a square metre. Whack those numbers into your calculator to find out the overall cost of the plasterboard. Add around $100.00 for adhesive and miscllaneous.
As far as sanding down the rough surface and painting over it……..you can try but you will still get an uneven finish. You can disguise the imperfections to a degree through the choice of paint. I know Haymes have a wall finish called Silk. It’s inbetween a low sheen and a ceiling flat. When applied it tends to flatten out and hides any shadows that may appear from using a low-sheen on a slightly imperfect wall finish. It can be washed down too which is handy.
Hope that helps
that helps alot, much appreciated.
