I painted the North side of the house two years ago (old Edwardian gaff).
It’s wetdash render, and was already painted white. The paint was in bad condition. I didn’t really know what I was doing at the time. I powerwashed it, but only lightly, a lot of paint was blown, I didn’t really go to town on scrapping this off as much as so should (only really discovered this after I started painting)
I painted it November, and it was damp and cold, so used pliolite, in the hope it would bond. I didn’t thin the first coat down.
Having just painted the otherside, with proper prep and thinned pliolite. I’ve checked the side I did 2 years ago, and there lots of section of paint that are ‘spongy’ to the touch. I’ve hacked these off, and it’s clear the paint has have not adhered to the wall.
There’s like a fine kind of chalky, grit on the render.
Any thoughts on what’s gone on and how to rectify these patches? Would thinned pliolite with white spirt work as a stabiliser, then reapply a second coat?
Thanks in advance
