Painted walls

[adrianw]

Am I right in saying you can't dot dab straight onto a painted wall and if so would I be able to if I used bonding agent first

 

[PhilPlaster]

You can. Use drywall adhesive, it'll stick to anything.

 

[adrianw]

Cheers bruce can't remember who told me you can't they must be a t**t

 

[PhilPlaster]

just make sure the background is sound first, free from dust and dry etc.

it must be pva/bond it mate.this has been discused a few times over the years.it will stick short term,but will come away in time.

 

[skimmin2day]

the pva will only be attached to paint too?????????
so when the paint breaks down so does the pva so does the adhesive.
straight on the paint for me,if paint is ingood condition

 

[goody]

nah it'll come away in no time and you'll be screwing it all back on wishing you'd pva'd it mate

 

[PhilPlaster]

Suppose its better to be safe than sorry but I reckon it'll grip no probs long term.

We tested this on a job a couple of years ago. The paint was sound. We cut a piece of board about a foot square and dabbed it straight on the painted wall. We did the same with a pva'd wall. Both pieces could be flipped off with one finger the following day. We used Betokontakt after that with no problem.
Just my 2p worth.

 

[S a plastering]

or create a key with your estwing scutch it up then dab over them

I see what you mean if paint is sound but if the paint is loose the betokontakt is still on loose paint isn't it!

But if it's that much of a problem why not screw laths up then screw boards to them
Or dab then put some mechanical fixings after dabs have set.

If the wall is flat you could use fixing foam (insta-stika) £6 a can do up to five full boards. Gun cost about £20 but can be used for loads of other stuff. It's one of those love or hate products. ;D

The point here is what you're bonding the adhesive or foam to. You need to create a key in my opinion.

 

[Nisus]

I agree, but what i want to know is why is he dabbing onto painted walls in the first place they can't they be that bad that they need boarding can they?? Can't they just be plastered as they are??
