Hi all,

Today, on my day off from the shop, I painted new stucco walls on the lanai.
The stucco is extremely heavy in texture and difficult to get good coverage.
I have an enormous amount to paint. I will be 90 years old before I finish
this huge task of house, garage and courtyard if I paint with a brush and a
roller on my off days.

There have been many discussions about spray equipment and spraying glazes.
This of course is paint not glaze. I am concerned about over spray and
getting paint droplets onto the new metal roof and other areas. Is there a
system to spray paint and avoid all of the contamination of surrounding
areas.

I know Vince is the spraying expert. Vince can you can relate to painting
a building? I have a compressor and a critter spray gun. I am willing to
purchase the necessary equipment for this job since I doubt that the critter
gun and compressor will do the job. Can anyone advise what is the best way
to go.

in SW Florida where the weather feels almost like summer and where we are
experiencing a banana explosion. At last count there are a minimum of 250
bananas at various stages of ripening on my banana trees. Another pod just
opened which means another 50+ bananas. Is that cool or what! Now if we can
just get them to ripen and cut them off the stalks before that fuzzy little
guy with the bandit face eats them all up. He has been busy with the
oranges at night leaving rinds all over the yard and then drinking water out
of the pool early in the morning before he retires. However, I am sure he
is keeping a sharp eye on the bananas.

Ingeborg -
I appreciate your faith in me as one of Clayart's resident know-it-alls, but
I really don't know much about painting buildings. The overspray is an
issue, but those areas can be protected with plastic sheeting. If you want
to reduce overspray, you might consider using HVLP equipment, in which case
you'd have a setup that you could also use to spray glazes (by replacing the
spray nozzle set with a larger one).

I know that the airless paint sprayers like the Wagner power-painters are
very popular. They don't work for spraying glazes at all, because the pumps
wear out immediately.

You really need to talk to someone more knowledgeable about spraying paint.
I've painted cars and trucks with standard high-pressure spray guns, but
never a house.

You might try using an 18" roller with a very thick cover. Used on
the end of a pole it is a very fast way of getting material on to a
wall. You might consider renting a professional airless sprayer,
which does put some overspray into the air, but not much. How many
square feet are you looking at?

Hi John,

The square footage is about 3300. I've gotten so much good advice from
everyone on this list but I am having a difficult time deciding. Spraying
will probably go faster and get into the deep texture better but then there
is all of that taping and covering everything I don't want to paint.
Rolling is probably a lot slower but not as much prep work and no overspray.
Hard decision.
