Spray Paint Or Roll Paint OSB!!

[biker]

Would you guys help me spend my money!. I'm almost ready to paint my man cave. Here is what I have 30FT X 60FT X 12FT. The walls and cealing is all closed in with OSB board. I would like to paint for better light but Some would say don't paint and some would say paint. If I do paint what would be better in the long run Spray or Roll Paint. I have read that water base paint is not good for OSB I don't know!! I'm thinking about useing the Barn and Fence Paint from Lowes. How would I find out how much paint I would need? That being asked for those that have done a big paint job like this please advise me the in's and out's to painting something this big.

Thanks.

I painted my garage with latex several years ago with no regrets. Prime first with tinted primer. Then paint. Be pepared to roll on multiple coats. I think I used 3 coats on top of the primer. Be patient, you'll know when it's enough.

I made a motorcycle shed about 10 years ago and painted the outside with porch and floor enamel. It still looks good today. It took 3 coats with a roller. I think that a roller would cover better than spray because of the texture of the osb.

 

[Jack Olsen]

In your shoes, I'd paint it. With a roller, probably. Lots of work, but worth it.

 

[bradleys]

I'm painting mine with a roller using the brightest, whitest latex paint I could find. I didn't use a primer. I bought two five gallon buckets, and I think I'll use it all. I have about 210 linear feet by eight feet high, which is 1680 square feet.

It absorbs more paint than plywood because of the very fibrous surface. It didn't absorb as much as I expected, because the wood fibers are covered with the resin or plastic or glue. I expected that it would absorb like particle board, but it didn't absorb near that much.

I did "one-and-a-half" coats. I went over the surface to get at least some paint on the entire surface. Then, while it was still wet, I re-coated to fill in the gaps. You can tell that it could use another coat, but it looks pretty good.

I'm primarily painting for brightness for lights, so I'm not overly concerned with a perfect finish. I'll go back and put on another coat when I get the urge.

I rolled out 55 gallons (50 with blue tint and 5 gal. of light yellow in the lathe & mill room) on my OSB (tinted primer/sealer followed by 3 coats). That's a 28' X 48' 2 story with 67' of interior walls. My neck was sore for a time from the overhead work. I own a airless spray unit but feel the roller gave me a better result.

I'll add this from another post I wrote a while back.

I would suggest a good sealer. GlidSeal is what I used from Gliden or PPG stores. It did two things for me, 1.) it seals/dries/waterproofs very quickly so the surface wood strands don't separate and raise from the OSB face when you introduce the slower drying water base paint. and, 2.) it seals the fasteners (in my case screws) so you avoid rust bleed. I used an acrylic latex (washable) trim paint by PPG called silver lining. It has a light blue cast to it that I think goes well with my gray machinery. I got a great deal on 50 gallons that a contractor didn't pick up. Might be worth checking with your local paint stores for something they WANT to move.

The barn and fence paint is OK at best. I used 2 gallons + painting a small cabinet and a tree house(outside osb only) last year, it's 8x8x8high. Spraying is great for latex paint, just messy as hell. I think it would cover better IMO spraying. That's a **** load of rolling unless you get the really really wide rollers. Nothing wrong with either paint for OSB.

 

[Dragster Racer]

I sprayed my osb ceiling with latex primer and then a coat of latex white. 15' ceilings, and the nice thing was that by the time the overspray and bounce back hit the floor, they were dry enought to just sweep up. So I have up on drop cloths because the got in the way of the scaffold.
Man, I will tell you. Spraying is the way to go. Go slow enough to cover but fast enough so that it doesn't drip off. No problem with coverage for me. But.....cover us stuff you don't want any overspray on. I didn't cover my garage door springs well enough. Should have. You can cover a lot of area with a good airless sprayer. The worst part is clean up. Takes a while to get the sprayer cleaned out. By the time I was done with the primer, it was dry enough that I just turned around and hit it with the top coat. Not including prep, I bet I did the 40x40 ceiling in about 4 hours.

100% Spray. Get a buddy and help mask anything needed. Rent or borrow a sprayer and spray the Kilz in the morning... And ifi ts warm enough , you could probably spray the 1st top coat of washable latex( kitchen and bath or Pearl/semi-gloss) Thats way too much to roll. And if you havent sprayed with a airless, you will be a pro in minutes. You can always have a buddy on a roller near bye if it gets too heavy in spots. If you can mask well, you can spray well

I did mine with a roller. The first coat was oil based sealer to seal the OSB and its ink and glues in. The second coat was a cheap latex exterior gloss. Everything tuned out nice and white with nice even coverage.

 

[jerkyboy]

I'd roll it and use an oil based primer/sealer.

 

[moatfruit]

Did mine with a wagner airless with the roller attachment.No overspray ,and really quick.

 

[boiler7904]

Spray it and then backroll for even coverage.

 

[35mastr]

Spray it. Way faster. I spray eveything that I can. Rolling it just takes to long.

 

[z28toz06]

I am using texture 111 on my inside walls. I have an 18" wooster roller that I bought when I built the house. 1/2" nap and it worked well.

 

[zeebad1]

Spray it and then backroll for even coverage.

This is what we did in our 56' X 72' X 16'......

Very pleased with the results....

I used Kilz oil-based primer first, and it didn't take as much as I thought it would. I think I used around 25 gal. Top coat is Sherwin Williams ProMar 200. A latex gloss finish, and it even took less than the primer.

 

[thdewey]

I found it much easier to prime the OSB before putting it up. I still have 6 panels to put up soon. I rolled the rest of my garage but I just bought a sprayer and I'd like to give it a try. A direct comparison. I'll let you know what I find.

Whether you spray or roll, for that much surface I would check out the Wagner Paint Crew. It's an airless paint sprayer, uses pro-style gun, but has a simpler "pressure on-demand" pump and utilizes a hopper instead of a suction tube, but works well for DIY projects and the cost (around $200) makes it worth the investment on large projects.

If you go the Wagner Paint Crew route and you have Menards around it is on sale this week for $179 with a $40 mail in rebate so $139 after the rebate. I picked one up for my basement and it worked great.

I just checked Menards on line the paint crew was $129 after rebate. It looks like a nice setup

 

[35mastr]

After you have sprayed with a decent machine. You will never roll again.

 

[TheNerd]

Well, I rolled mine, wasnt happy with the textured look, mudded the entire thing, rolled it again. Looks pretty good now, but LOTS of work.

 

[bryna]

I caulked all the seams with a paintable latex caulk first. Then I sealed with a good quality Sherwin Williams sealer/primer. Then one top coat of white satin interior paint. There were a few spots where the OSB bubbled out where I'll have to go back, peal it off and re-coat but overall I'm very happy with it. I used an airless gun to apply then backrolled it to make it even.

 

[jdub63]

Zeebad, How did you make your stripes so clean? I rolled mine, and the tape lines were very jagged(sp). The tape wouldn't seal well against the rough OSB. I was considering changing my stripes to vinyl tape...

I used a Powermate with roller attachment. Next time spray and backroll.

Heres a post i made a while ago....If you need help, PM me and i can help you...

"Im a professional house painter( i know it *****) As long as your base color has a few days to dry and the walls were primed proper, it shouldnt pull the paint off. Ive always used a 4 foot level and a pencil. You can get a closer tape edge to your line then chalk. I use a clear/white tape called "easy mask" Clean Edge. One of the tricks is to, after your tape is on, take the back of the putty knife or something else that you can rub somewhat hard on the tape without scuffing it. Instead of the roller to paint up to the edge of the tape, i use a brush and go quickly cut the tape edge in with a light first coat. Sort of paint down away from the edge that is getting painted, so you dont force and paint under the tape(if it wasnt properly rubbed down). Go around the garage once, and then hopefully your using latex , you can usually immediately hit it again with the brush with a second coat which should cover. Another trick is when your pulling the tape off, make sure you pull the tape "UP" if the new color is "Below" the tape edge. This way it kind of breaks the edge and the paint cant pull off with the tape any higher than the edge, if it started to dry. The best way is to pull the tape off still wet if possible, and it should pull away clean with minimal touch up. If you want the paint to dry first around the tape, then use a sharp exacto blade and lightly cut the edge of the tape/paint line and it should come off. Then simply roll away......This picture of mine was painted on OSB ! "

Thanks guys for the help. You guys are good. I like the idea of the paint feed roller. I will post pitcures before and after. It will probley take some month to do.

Thanks

I have two walls of OSB and I painted mine with a roller. I primed first with Kilz then rolled a satin latex over that. One of my OSB sheets was rated for outdoor sheathing and took the paint very well. The others were not outdoor rated and I experimented first using latex paint without the primer. This caused some of the strands to peel up before the paint dried. Because of this I decided on the Kilz primer because it is solvent based but dries fast. This helped with the problem of some of the strands peeling up. If you have the outdoor rated product it has a coating on it that solves the problem.

Zeebad, How did you make your stripes so clean? I rolled mine, and the tape lines were very jagged(sp). The tape wouldn't seal well against the rough OSB.

They're not as sharp as they look in the photos. I had some leakage under the tape.

I did use a good quality masking tape from the Sherwin Williams store, and did spend a fair amount of time applying it. I just shot the line with a laser level, and away I went.

Thanks Ben. We just got through our 3rd party in the past month. College graduation party today for the youngest son, big cookout on Mothers Day, and birthday party for the oldest grandson.

I knew this building would come in handy!!

 

[Leeboy20]

For the interior, i flipped my OSB over and put the smoother side/sticker side up

I figured that was what everyone was doing....Boy the rough side would really soak up the paint wouldn't it?

Before I built my home 12 years ago, I had never heard of a 3 ft. roller. Home Depot has them. After cut-in you can paint a standard room in 5 minutes. Wonderful time saver. We worked out a system where I would roll the room and the wife and a friend would follow with cut-in. I never was to great at that anyway. Painted the whole house (3,500 sq. ft w/9 foot walls) in one day. The ladies got their system down where they would cut-in the ceiling and wall at the same time. I finished ahead of them naturally and did some cut-in myself.
I am getting ready to repaint some rooms and you can bet I will be getting some new rollers for the big boy.

 

[biker]

Okay!!! I tried to roll the ceiling and finished half with 5 gallons of Kiltz oil base primer. I won't finish painting like that. It looks good but at 12' an 18" roller gets heavy. The rental center wants $60.00 a day for renting an airless sprayer!!! Its going to take me two to three days to paint by myself. Ha 3 days $180.00 I don't think so.

Have anybody here ever brought the Reconditioned Wagner Model 770 Paint Crew from Northern Tools?? If so, did you like what you got? I feel like I could buy one from Northern Tool cheaper than from E-bay. I haven't never had any luck from buying from E-bay.

 

[Leeboy20]

Its should only take 2 days...... I coat of primer....Let it dry over night...Spray the first coat in the morning , and give it 4 hours or so ( even turn a little heater on) and do the last coat at dinner....(hopefully your top coating with latex)

 

[Dan in Pasadena]

I'd roll it personally...and I own an airless sprayer.

Dumb questions for OSB owners: Does it hold a drywall screw (for example) as well as 3/4" plywood will?

Have any of you done a skim coat of drywall joint compound to make the surface smooth appearing (like drywall)? And if so, would this be done on the raw OSB or would you do it between a couple coats of primer?

 

[Leeboy20]

If i was to skim it, i would do it after the 1st coat of primer, to make the mud slide easier and not abosrb into the wood. Then just spot prime the areas and paint

 

[biker]

( even turn a little heater on)

Hey Man its 98 degrees here at 2:00 PM Ha Ha

 

[biker]

Well guys! Here are some pictures of my shop before I painted it.

More pictures to follow.

 

[biker]

Here are the finished pictures. I used an airless sprayer and had a friend back roll the oil base Kiltz primer. The sprayer did the primer good. I brought a 4Ft long extenction nozzle and I could reach my 12Ft ceiling good. Did that in about 4 hours. The shop size is 12Ft X 30Ft X 60Ft so it is not small. That was good cleaned the sprayer up and started to spray the Barn and Fence White water based paint from Lowes. WRONG I wont do that again!! The sprayer would not spray the water based paint. The paint is so thick wouldn't run of the mixing stick. I thined the paint to 2 part water and 1 part paint. Still would not spray. So I ended up rolling the walls and ceiling. Tock me about a week to finished. I'm happy with the way it came out. I did two coats on the walls and one coat on the ceiling. Now I have to clean the paint off the floor now. Here are the pictures.
