assembly table masonite top warped due to moisture from treated lumber

[Brian Runau]

I redid a small step outside our back door last week and sat the still wet treated lumber on my assembly table for 24 hrs before I used it. Homer Simpson duh moment. The masonite top curled due to the moisture it was exposed to even though the top was waxed.

Any way to re-wet this thing and weigh it down while it dries to flatten it out or am I stuck with the curl and must turn the top over and let it flatten itself out?

Thanks.

In my shop, masonite is a throw away product.

It is replaceable, but I prefer to not be wasteful. It is fairly new. Do you have any suggestion on how to flatten it other than turning It over? Brian

I have a pretty big pile of it for covering floors in old houses we work on. It gets leaned up against a wall, and develops a bow, but it will flatten back out on it's own if the bend is not too severe. I would first try just laying it out in the Sun to dry out the wet side, but not on something wet like grass.

Did you measure the thickness? I'd imagine it swelled a bit.

Maybe slide some stickers under and put a fan on? Masonite has quite an ability for wicking moisture.
