Has anyone came across this before?
Looks like there has been a leak in the ceiling and it’s gone between the boards. Defo been no leaks though.
It’s been sprayed with airless jub 3 coats, then sanded and sprayed with base coat paint. This only showed up really on the next spray paint coat...
Does anyone on here that’s using a airless plaster machine have problems with the gun going a little rusty?
we are putting it in a bucket of water each night to stop it blocking but it’s obviously going to rust.
an alternative would be much appreciated. Thanks
