Need to seal wood?

[jeff6898]

Ok I am building a combo that holds 16 15qt tubs and 8 28qt tubs

I bought cabinet grade plywood unsure of what the actual wood is nice and smooth and straight.
Do I need to seal the wood? If so what do I use? Will it say wood seal on the label?

When I built my very first rack I made it out of regular wood and I used thompsons water sealer that comes in a spray can and is used for outdoors stuff.

Thats what I used when I did mine. Hope that helps

Yes!!!!!! If not you will get moisture and bacteria. You can polyeurothane (sp?) it. That is what we do with all the cages we build. I would recommend at least 2 coats.

I also think you should seal it so it can be cleaned and also to keep it from rotting and growing mold, I used a stain and then water based Polyurethane to seal mine. I would let it air out until you cant smell any fumes anymore probably at least a week.

You also might want to put a bit of caulking in the cracks as well. Not a ton...just a thin strip.
