recomadations from painting pros

[little d]

Ok guys, i built a tool box this spring for the pu. 4' by 6' by 16", it lays on the floor of the truck bed. i built it outa treated plywood and coated the top with bed liner. it looked damn good for a month and then started to peal. now its to the point ya cant even tell i coated it at all. my question is this, how do i seal it with bed liner and make it stay? Thanks in advance, D.

Regular plywood? Treated plywood? Marine plywood?

If it's regular plywood it is going to soak up water and you're not likely to keep any coating on there long.

it's treated.

225 hits and no one has any sugestions on how to paint this?

How wet was the plywood, you need to let treated lumber dry 6-12 months before painting or staining. I would chaulk the seams, prime with a quality ext primer and put 2coats of quality paint.

Sand butter smooth. Any crevices/knots will let water seep in, and blow the paint out.

You'd probably fair better with oil based everything than latex--especially if its going to be exposed to the outdoors constantly. Oil paint will be smoother as it evens out nicer, so that water will sheet off easier.

By the way, which parts are peeling? And what color did you paint it?

--In humid environments, with lots of sun, I'd imagine a black painted plywood box would deteriorate at a much quicker rate than one painted white. If the tops are peeling the most, make sure you put on a nice primer, and perhaps even modify your box with a slight slope. (Just put a 2x4 on end closer to the cab, to elevate it a bit, and promote water sheeting).

I recall (don't quote me) that oil will stand up better in most times, but in really hot and humid environment, a latex MIGHT fair better.

Hope this all helps. More details could dictate better answers.

I just re-read: bedliner....

Probably not made to be applied to 'anything'. If you did all the necessary prep for it, and it still peeled, perhaps its not the right product for the application.

josall, it was dry when i built it. i cant tell ya what moisture content was but it was dry. i want to use the bed liner on it.

BMWWW, i'm not a painter, always sub that out, anyway, i just rolled the bedliner over the plywood, no prep. the instructions for a pu bed is wash, ruff up, wipe down and apply. I figured it was good to go, wrong! Would you sugest a primer? and if so what kind?

 

[josall]

I would test a scap pc of plywood and put an exterior oil base primer then bedliner. you might call maufacturer see what they suggest.

 

[kmacht]

Bedliner paint is usually meant to go on metal or fiberglass type surfaces. They are non pourus. I would do some research online to see if it is meant to be put on a pourus surface. Maybe the wood absorbed some of the chemical of the bedliner and didn't let it cure properly? If it is just the grip type of surface you are looking for you can buy stuff that mixes into regular latex paint. You can also buy sand paint to get a semi-rough surface.

josall, i like the oil base primer idea.
kmacht, didn't think about that, you might be right. i think i'll try the oil base primer idea of josall and then try it. i want to use bed liner because its tough stuff, i throw tools ect... on top of the box and what ever i put on it has gotta stand up.

thanks guys, D.
