Out door paint gun

[the lone]

ive got a 12ft x44ft covered patio outside, and the underside of the roof (the frame work) is exposed. the posts are treated wood, but the rest is not. im looking to paint underneath the roof but using a brush and roller on a ladder sounds like alot of work. ive never used a paint gun like a wagner or similar. any suggestions on what to buy to get the job done. and what kind of paint to go with. and pricing. its outside, but doesnt get exposed to rain, but it is very humid around these parts often.

Rent a good airless sprayer. If you have everything all prepped, you may be able to get everything painted and the sprayer cleaned up within a 4-hr rental period.

Kert you must be fast...takes me about 40 minutes just to clean my airless...VBG

the lone....first off what kind of wood are you planning to paint? Is it new wood or has it weathered?

If it is new fresh lumber then you should prep the wood to accept the paint. The milling process these days is so high speed that the lumber gets a glaze and paint can't penetrate. There are clear products you can spray on that break up the glaze then paint.

If you are using an airless sprayer I would backroll. That is the way my wife and I paint our fence and house...well it is until ladders over 6 feet are involved then I do both.

There are some who can spray only but they either have lots of experience...or none....
you can cover a lot area with the sprayer and back rolling is as quick as you can roll.

Also be aware that even though it is airless the overspray will travel a long way and you must cover anything and everything, beside, around, under, before, past, over and generally within 20 feet....especially new cars....this is asumingno wind...if windy all bets are off.

I would use a modified solid stain. You can clean up with water but the base is like an oil based stain. I've used Flood stains and have had good results.

Be aware of wind, air temps, substrate temps....you may be shooting at 4 in the morning...

Good luck with it....BTW I bought a Wagner that has a one gallon hopper on it in the early 90's and I still use it. Replaced the gun and the hose is next but it has paid for itself many times over.

If you have a suitable compressor ,suggest you investigate Wagner HVLP conversion gun from Gleem Paint. A pressure pot system would be best. Check Craig'sList for pressure pot systems.

I do have a compressor in the garage. Its big.

What does pressure pot mean?

What does pressure pot mean?

That is the type of spray rig where the pot stays on the ground or at your hip. Air pressure in the pot drives the paint up the hose to the gun. That hose connects to where a siphon pot screws to. The air to spray is in another hose, just like a conventional gun.

Actually, PP's and siphon units are both known as conventional. The nice thing about the PP is that you are not holding the weight of the paint and you can use the gun at any angle including up side down. I love a 1 qt. PP for painting cars.

If you really want to put up some paint, you can do so with a PP because you can dial up the pot pressure. You can overcome the gun's ability to atomize the paint. The old Zolatone texture paints used a PP.

Airless is good. For a novice, I'd rent the airless. Learn to hold the gun perpendicular to the work; don't fan your strokes. Don't be afraid to get close, like 12" close. A lot less overspray if you master those 2 techniques.

Spraying up can be messy...do several light coats or you will get dripping/runs

Oh you are going to have fun covering that OSB....the top side is textured so you don't slip on it but the bottom side is smooth and usually has a wax on it...also the product stamps tend to bleed through.

If you don't have the paint equipment I'd just roller it with a roller on a pole. You can have it done by the time you tape off the house and put up plastic to protect everything.

If it was mine I'd seriously consider putting up some aluminium soffit material instead of painting.

 

[Zeke]

Well, any kind of painting is work. There are the trade offs like masking for spray taking time but the painting operation going quickly.

Some other advice, pay attention to getting the proper primer.

Explain aluminum soffit? All good advice fellas. Thanks.

A soffit is an overhang and when referred to as a "soffit" is usually covered or boxed in. He's just talking about a covered ceiling using the typical goods manufactured for the purpose of covering the underside of an outdoor structure.

i see....i thought about that too...havent had a summer here yet....dont know how hot its going to be...but its always windy. i live in a coastal county.

I used an airless spray gun to paint my garage. Sure I spent several hours masking/covering stuff, but the painting took all of maybe 2 hours/coat for the entire space. (16' x 20' x ~9'). using a roller probably would have just taken me longer to do, as I still would have needed to cover and mask everything.

Disposable plastic "drop cloths" are great for covering large areas, and they're available in some pretty decent weights. I'd box in the whole porch with the stuff and really weigh it down against the wind. I've even hung a few up in my garage a temporary spray booth.

HVLP= no over-spray=less masking=less time

Remember once you paint something you will be forever repainting it. Id check into some type of system to cover the ugly wood that never needs painted.

Second looking at Gleem Pain.com. look in their refurbished line. I have picked up two nice units that were all but new out of the box at a great reduction in price
