Just wondered if i could ask you for some advice. Customer had a waterleak in downstairs shower room, all fixed now, but some patches on the painted wall are bad due to water ingress i think. Paint has bubbled (a very dry bubble of paint) and under the bubble is a very chalky feel, even powdery. Other areas have bubbles where paint has lifted but not dried out to such an extent. If i peel the bubbles in those areas bare plaster is revealed. Whats the best way to prep walls for painting? Was thinking of scraping and sanding followed by Everbuild 406, mist coat, then paint as usual. Trouble is i cant find a stockist of 406 locally
Zinsser Gardz is similar - can you find that locally? But, yes, if the surface is dusty/chalky or otherwise dodgy, these products seem ideal to bond, seal and prime the surfaces.
Did consider Zinsser Gardz, but thought Zinsser Bulls Eye 123 Primer might be better in reply to a PM, op sent me. What you reckon DA.
I can get 123 in Dover, gardz will involve a 25 mile round trip. Not worried about mileage, just want which ever products is the correct one for this problem
Didn't know there was an outback in Dover, 25 mile round trip & I thought it was bad here in Somerset sourcing things. Very surprised your can't get Zinsser Gardz locally, but you can 123.
Its nice living in the countryside but there is nothing in between towns. Gotta travel if nothing locally stocked
If the surfaces are remotely chalky, dusty, damaged (eg crazed or slightly cumbly) or particularly porous, I would personally go for 406 or Gardz. These are both very 'watery' and are designed to soak in to bind and adhere the surface making it secure. They also both adhere really well to pretty much anything that's on there - traces of old paint, etc. I'm not a pro, but I know what I would use.
Yeah, what I mean is I wouldn't use 123 here. It probably would work, but I like the idea of 'soaking in'...
Gardz it is then chaps. Thanks for your help, will let you know how i get on. Last thing, will i still need a mist coat?
No mist coat as Gardz will sealed the surface ready for painting. Gardz info: http://www.zinsseruk.com/wp-content/uploads/2012/05/Gardz.pdf
