P.V.A

[Basher]

Allreet lads do you allways give re-skims two coats of p.v.a i have found recently that the skim starts like to pull apart in some places if you get me also do you knife the walls if they have been painted??? Many thanks for all the advice.

 

[napper83]

depends how big the room is and how the first coat sucks in

 

[Basher]

so it dont matter if you only give it one coat of p.v.a then?

 

[napper83]

all pva is used for is to control the suction if u need to generate a key you should be using a gypbond or similar

one coat of pva to seal the wall..... then the second coat to stick the plaster to the wall.
if the walls are sound, one would be fine.

I know what p.v.a is for put i allways taught the way skyzoo has said one coat of pva let it go off then another coat let go tacky then skim away

 

[napper83]

if the first coat is still abit wet by the time ive put it on an filled my water buckets it gets skimmed if its dry it gets another coat unless its a small room then the quicker it pulls in the better really

I have a ceiling to re-skim on tuesday evening so if i pva tomorrow night can i skim it tuesday night?

 

[christ]

instead of pva i use stabalizing solution to seal the walls.... then pva

Unibond super PVA is the best on the market and if you shop around you can pick it up for £20 for 10 litres, which is roughly what you pay for most other PVA's, you will always be able to get the cheap stuff but I would'nt bother, as for how many coats the way I see it is Unibond know more about this than any of us so if they say two coats then thats how much Im putting on
