Painting Plywood Need some help
Iowa883
I have decided to go with 1/2 in. plywood for my shop walls.
How do I start, do I need a primer or do I just go into it with paint ? I am
painting the walls and ceiling white.
Also, another figure for you painters, here are my shop dimensions. How much
paint/ primer will I need ? 24 ft. wide X 40 ft. long X 12 ft. high.
Any particular brand of paint/primer for years of service ?
Thanks so Much,

Unless you don't care if the paint is sucked up more in the soft grain,
primer first. Oil primer.

24x40x12 = 11,520 sq.ft. You don't have any doors or windows?? :)
11520 sq.ft / 400 sq.ft per gallon (optimistically) = 29 gallons per
coat. Plan on two coats, both primer and top coat.
If you want long service, use oil paint. If you also want easy
cleaning, use semi-gloss. Not going to look great on plywood though.
Neither would latex.

yes primer is cheaper than paint. if you are using a color, have the paint
store tint the primer close to the finished color, it will save a coat. each
gallon is 400 sq ft. (depending on thickness) ... you have close to 2500 sq
ft to cover.. that's a bit more than 6 gallons per coat... first coat
absorbs a lot. probably need 2 complete coats & a touch up coat after that.
if you spray it or use a heavy napp roller you could easily use 25 or 30
gallons. happy painting.

that's cubic volume
its (24*12)2 + (40*12)2 +24*40 (ceiling) =2496 sq ft. div by 400 = 6.24
gallons per coat

I wasn't going to get that complicated but if you have some free time and
subtract that from my coverage go ahead and be my guest :-)

, how about a primer that is white and can also serve as my paint ? Do they
make such a covering ?

check the home stores for pre tined paint. I have use it for years as a
primer. As long as you do not get some dark color then try to put a light
coat over it. Recently I wanted some block fill for my fence. I found a 5
gallon container at the depot for $25. Mixed it with some water and my
sprayer went to town. I put 2 coats of my color over the top and everyone
says how nice it looks.
Just do not try mixing latex and oil doing this.

Yeah, my brain was disengaged, I'm really not a paint salesman :)

You could deduct about a quart per coat.

I get closer to 1500 sq-ft ((40+24)*2) * 12.
First coat over plywood will be closer to 150 sqft/gal, top coat about
300 will probably be better estimates. You'll need one primer coat and
(probably) two top coats if you want a real good coverage.
I'd go w/ a glossier top coat to shed dirt and reflect light better for
a shop.

Probably don't need the mildewcide unless you're in a really humid area,
but wouldn't hurt. Primer isn't intended as a top coat and won't serve
very well as such.
At that point you're getting into whether you're looking to get by cheep
or want a good job. An enamel top coat (can be latex) of higher gloss
will be much easier to keep clean, last longer, and reflect light
better.
I would probably have a white tinted just a little to keep it from being
"too white" and being blinding to look at directly...

Primer is normally white. Sure, you could use it as the final paint but
it isn't exactly what i would choose for a shop. You're better off
priming, then top coating.
Note that I had a brain fart when calculating the area and the correct
amount is about 6 1/4 gallons per coat assuming a coverage of 400 sq.ft
per gallon. If you subtract out the doors and windows, 12 gallons for
two coats should do you if the walls are reasonably smooth.

You can just leave it as primer. Primer will not hold up as well over time,
is flat and does not clean as well. Right now I have about half my garage
insulated and sheetrocked and primered. I'm waiting until it is all done to
put hte finish, but it does not look all that bad.
Since you need more than one coat, using one primer, one finish, will still
give the best overall results. Primer will allow the finished coat to cover
more space with less paint.

So,
I need to either stay with oil based or latex for the primer and top coat ?
Thanks,

Add the ceiling of 24x 40 to that .
I do agree that the first coat will be much less and maybe 300 sqft for the
second coat.

OP: "I have decided to go with 1/2 in. plywood for my shop walls. ..."
Don't see anything about a ceiling there... ?)

Not necessarily...the other post was talking about taking a bunch of
returned or other low-cost paint and using it as primer...was mixing all
the various things he found together--obviously, that would have to be
at least all an oil- or latex-based to have any chance of mixing well...
There are both oil and latex primers suited for either oil or latex
topcoats. The particular primer will say whether it is/is not suitable
for a given top coat.

Ok guys,
I have decided to go with 1/2 in. plywood for my shop walls.
How do I start, do I need a primer or do I just go into it with paint ? I am
painting the walls and ceiling white.

Do you see it now that I added the space ?
dadiOH
The calculation is still wrong. I knew mine was but I figured the guy
that cprrected me was right and didn't check it. It should be...
((40 + 24) X 2) X 12 = 1,536 sq.ft.
Divide that by the 400 sq.ft. coverage per gallon and you get 3.84
gallons per coat
francois...@hotmail.com
40x24 = 960 sq.ft.
1536 + 960 = 2496 sq.ft.
Longshot was right...

Thanks for the input and compliment on the size. The actual size of the
whole shop is 40X56 but my actual shop "shop" is the dimensions above. The
rest is just personal storage. I own a motorcycle repair shop and this is my
new shop.
Thanks,

In addition to the excellent advice you've gotten from others, I use a
sanding sealer, especially on non-veneered plywood, before priming.
This will raise the loose grain, which you then lightly sand off
before priming. It makes for a smoother and more consistent finish and
one that requires less paint.

Very good point I intended to mention...
