Now that my basement drywall is all mudded & sanded, I need to prime
it and would like some advice.

I have one of those smaller 2200psi airless sprayers (borrowed from a
friend) that has the hose to stick in the paint can. I'm going to try
that hoping it works OK for me.

I have no worries with overspray in my basement, except for the
multitude of outlets and light switches I have in my walls. Any
advice on a quick and easy way to protect them from the paint
sprayer? I obviously don't want to get paint inside my boxes if I
don't have to.

Also, what is a good, sprayable primer to use on my new drywall?
Should I use latex, water, or oil based? Should I need to thin it?
Should I expect to need more than one coat? I plan on painting with a
relatively light colored latex after priming is complete.

I'm estimating I'll need about 6 gallons of primer for the first
coat...maybe more if this sprayer puts it on heavy or not.

Thanks for any feedback.

I like working with Sherwin Williams products. I believe latex *is*
water based. How many coats depends on how good You and the sprayer
are together. If the fan shaped spray leaves lines at the outside edge
the tip may be worn, always keep the gun moving when spraying,start
with fast movement and gradually find the proper speed..Thinning
depends on how thick/thin the paint is to begin with and the spray
rigs' ability to draw it from the bucket/can.
I've heard Painters use the term "dusting" many times referring to a
very light primer coat,,personally I like primer coverage that
prevents the color coat from soaking into the wall..The primer can be
tinted the same as color coat or to a varying degree but that does'nt
help to get an even sheen when using any paint with a gloss level.
Have plenty of warm water to flush the sprayer completely till no
paint is left in the rig at all..If spraying is stopped before
complete drop the gun into water to keep the tip wet for short periods
while You attend to the problem.
Have plenty of light and someone to keep it at an angle to the area
You're working on..Check/clean the filters in the rig and gun
before,during if needed and after just for good measure..Lastly have
one more helper there with a roller to backroll if there are problems
with the sprayer but You still want to make good time.
Sorry if I gave a long reply,,I'm sure there's alot more tricks n
tips out there too.
