I’ve seen a few videos of folks using the HomeRight sprayer with Poly. I’m about to finish a pretty large project and I’d like to use mine (still in box) to finish the job versus using a brush.

A few questions -

1. In using a sparyer (my first time) does it reduce/eliminate the need for as much sanding between coats? I know it’s a light sand any way but curious if the sprayer, since there are no brush strokes, eliminates that step.

2. If the sprayer oversprays onto material with existing finished poly – would that create a very visible overspray?

1st coat will probably always need a light sanding after for any grain raising. After that it really depends on technique and environment.

Over spray being visible really depends on the situation. Is the finished piece perpendicular to the unfinished? If so I would do very light coats to prevent any pooling at the inside corner.

Practice on scrap to tune the sprayer in they way you want. I don’t have any experience with the HomeRight sprayer, but it looks very similar to an inexpensive TackLife brand sprayer I use for spraying latex. Fan pattern and spray density should be adjustable. Even with poly, I would strain it before putting it through the sprayer. It doesn’t take much to turn a great spray job into a profanity storm.

1) Spraying .vs. brushing does not change need for sanding between coats.

2) You don’t mention which Poly? Hard to answer question on over spray?
I spray Arm-R-Seal all time. Oil based Poly over spray is not like conventional lacquer/solvent top coat over spray. It does not ‘dry’ in air and create classic over spray ‘dust’. It stays wet for long time. For unintended surfaces, it will dry to create an almost orange peel looking surface if not removed, or wiped down. Over spray on to wet surface will usually self level, but have to be cautious about pooling/runs if applied too heavy. I will often spray two sides of project, and then pause to use a foam brush to fix any runs on 1st surface, then repeat. Once you figure out proper film build to apply, touch up is not needed. I find it is easy too spray too much poly and adding 10-20% of fast drying solvent like naphtha helps reduce the film build.

FWIW – A water based poly will behave same way with high ambient humidity. Need to use alcohol/acetone to thin WB and reduce film build.

Spraying poly is a little more tricky than some other finish types as you have much less solvent evaporating as you apply the finish. Practice proper film build on both vertical and horizontal surfaces before attempting on actual project.

Best Luck.
