Weatherproofing a birdhouse

I would go with anything water-based or shellac. Anything non-toxic.

Particle board is the wrong "wood" to use for outdoor projects since it tends to weaken and fall apart when exposed to water. Since you have already finished the project, an outdoor paint would be fine. Make sure it is completely cured, about two weeks, before placing outside. Any of the film forming finishes including paint will be nontoxic once fully cured. If you really want to go for it, try the epoxy coatings that are made for marine use. That will completely waterproof it but it is overkill in my opinion. Lacquer would be the worst film finish that you could use for your application.

Good Luck.

The political signs that are plastic but look like corrugated cardboard boxes make outstanding roofing material for birdhouses. I always knew there had to be a use for those damned things!

Should have built it out of cedar fencing material, then the weather won't bother it.

Joe_Ste> Hi guys,

That's called Coroplast, and it also makes excellent tails for radio control combat planes. Print shops often give away odd shaped and/or colored scraps for the asking.

Paint will help protect it. Do not paint the inside. An asphalt roof shingle on top will provide added protection.
