Aquaplas

Post by fishgitr » Sun Sep 30, 2018 8:58 pm

I have left over aquaplas that I am going to use for trim tab wedges. Is this stuff water proof? Should I epoxy over it or should I glass it?

I'd glass it on to keep it from moving and avoid water ingress.

I am facing some of the same decisions with corelite and plan to immersion test for a week.

It seems like it might take a bit of water on edges.

Weigh part, soak for a week, dry with paper towel and weigh again.

Thanks fallguy! I guess I’ll glass it or at least coat it a couple times with resin!

It's PVC, I never heard of PVC absorbing water but feel free to test.

I have some seadek teak sample here and it says it is non-absorbent, too.

Some of these modern marvels are really great.

I think the seadek gets moldy from the surface they put into it.

My wife gave the go ahead to use it in the living spaces, but I am going to avoid the rangetop as it doesn't look too washable.

Otherwise, testing is only done when doubts are high.

The corelite material I have is very brittle. Holds screws well, but edges break ez. So I will glass it all to keep it from chipping where used. Point is, consider all facets.

Aquaplas is a PVC foam. The cells are closed but it is manufactured as a block that is sliced to make panels. The cut through the cells make the surface a little bit porous but just the surface. Thanks to those very small open cells, we get a mechanical bond with epoxy but it is not open enough to absorbs water. If left raw, that surface will absorb dirt and that may lead to the idea that it absorbs water.
I would not use it as a countertop, it is a core material.

JM would I be ok to coat it with resin, prime and paint it for wedges. I am through bolting trim tabs and would be using 4200 or 5200 to seal them. Would that be ok?

Yes, that would be fine.

Thank JM! Would you use 4200 or 5200?

Fallguy our paddleboards get stacked all the time with dirt, grass and wet. They will set for days and the padding looks like it is the same as SeaDek and I can't remember once mold growing on it. Sometimes when I pull them apart to load on a trailer they do smell of decomposing organic matter but it rinses right off. We do get a lot of red clay stains on them regularly that for the most part bleach and "Dawn" dish soap removes. We did have one board that had tire tracks on it and had to do a little light sanding to remove the tire marks. Anything sharp will tear them or cut them. But it is unbelievably durable.
