We've been getting bids to have the trim on our house repainted. Two
of the bids were, we assume, for traditional brush-and-roller
application of two coats (along with all the extras - pressure
A third came in a lot lower, because the guy thinks he can do it in
one coat. He uses a sprayer instead of rollering it on.
Will a sprayer give us good enough one-coat coverage that we could
feel comfortable going with this bid? This painter was recommended to
us by someone who observed that the houses he painted in a certain
neighborhood stayed looking good much longer.
If it matters, we're going from a pale yellow color to an almond.
I have sprayed about 100 gallons with an airless. For some jobs, it is the
only way to go. The problem is that it gets so much overspray on
everything, it is next to impossible to spray it without getting everything
messed up, even if you were an expert masker and took exceptional care. I
sprayed large areas and block walls.
The time involved to properly mask a job, and take exceptional care makes
the job last so long that the bidder has to up the price to cover all the
extra time. Sure, you will get a thicker coat, but it will be thicker on
everything. Roof tiles, windows, doors, you name it. Things you don't want
painted. Then you have to clean it off, or paint that stuff with another
brush. Thicker paint also runs.
For big areas, a sprayer is good. But, for cutting in, trim, doors, and
windows, you cannot beat a brush or roller.
yesterday,I walked by a house that had been sprayed.
Much masking of windows and so on.
Some overspray on surrounding vegetation.
Very uneven paint coverage.
I have had our house painted a number of times over the last 25 years.
I cannot imagine spray painting trim.
Yeah, you can get coverage with one coat sprayed, but there'd be so
much masking involved in spraying trim it's not even funny. And if they
don't mask well you're bound to have something oversprayed. I'd go
with brush and/or roller.
I've used both a brush and rollers, and an airless sprayer. I was able
to avoid overspray problems, and the sprayer gave better coverage with
Since you are hiring this done, and apparently the painter has good
references and a lower price, I would go with the sprayer.
You've had several responses, but I'll chime in as well.
Airless sprayers are excellent for getting paint onto a wall. If the
surface to be painted is smooth and has no irregularities (something
like hardiboard or similar smooth surface) then spraying with an
airless is all that is required for the large areas.
You encounter problems wen using an airless to paint irregular
surfaces, something like wood siding that has been painted and has
peeled and been scraped and repainted many times. In this instance,
the airless is still a good, time saving tool, but not the only tool
you need for the job. Use the airless for the same reason you use the
roller-to get the paint on the wall. Then use the brush to insure even
and complete coverage.
As for painting trim, the airless is not a good tool for that. After
using the airless to prime the entire surface and paint the large
areas, it is time to put it away and break out the good paint brushes
and spend a little time.
Done this way, the house can get sufficient coverage such that one
coat will work fine. Two would be better and make certain you get the
best results. Of course it also takes more time.
How long a paint job lasts has nothing to do with the method of
application and everything to do with proper preparation of the
surface to be painted and the quality of the paints used. So long as
comparable paints are used with similar coverage and the surface is
prepped correctly each method should last just as long as the others.
As for over spray, drop cloths in the right areas and the knowledge of
how to use painting shields, contains most of the over spray you will
