Airless spray vs roller vs air spray for Primer

Post by TomTom » Sat Aug 31, 2019 11:42 am

I will be using Jotun HB primer - directions say airless spray or roller; I have an air spray machine - what would be the disadvantage of doing it with this?

Airless vs air?

Air sprayer overspray and losses, or you might have trouble getting high build thin enough to flow (likely).

If you have trouble fall back to rolling.

Hi build primers probably have some thixotropic agent in them like talc that will flow poorly.

An airless sprayer is essentially a delivery system that would still require rolling to finish.

Silvertip system three high build primer can be purchased with hardener for spraying and has instructions for proper thinning.

I have had no real issues with it spraying with a hvlp air sprayer.

Hi TomTom,

Like Narfi, I sprayed S3 HBP on Penny with a HVLP...no issue whatsoever.
