I am spraying on new interior walls in a basement and was wondering if it is best to roll after spraying with an airless sprayer to even out the paint? And is it possible to get away with one coat of paint? I sprayed primer on before texturing and will prime after texturing also.
The back-rolling is usually done to 'push the paint into the wall' to insure adhesion, not to even it out
Hopefully you back-rolled your prime coat
I'd recommend it for the first color coat also
Not for the second
Two coats paint is always recommended for numerous reason
When using a sprayer the paint goes on as a dust and somewhat drys as it flies through the air onto the wall. By tis happening the molecules that are supposed to bond do not get a full chance to do so. Back rolling the primer is extremely important and so would be the first coat of paint. I would agree that two coats should be applied. Also, when home builders do there quick coatings alot of times paint will peel or bubble.
In addition, any wall paper applied to this lazy quick way of painting will peel very easily and usually at the seams. Builders tend to do a coat of primer and 1 coat of paint , tinting thier primer if needed. There should actually be a code to apply the paint the right way enforcible by fines and lawsuits! My in laws house cannot hold wallpaper and some rooms are just unmanageable. You just keep peeling and spackling till you have to do it again a few months later. Shame on those builders that do that!
