covering raw balsa wood
#1

Ok
First it's been about 10 years sense I have covered a bird with fabric (Super Coverite )
So the question is do I need to coat the wood with a Thinned coat of balsa-rite, lacquer sealer, what ever.
don't what to start a debate just suggestions.
thanks in advance

Not totally necessary but some will add Balsarite to the edges of parts that get covering stuck to them to help with adhesion. Some will also add a coat of hairspray (no balsarite) and then lightly sand with 400 sandpaper to get the smoothest surface. IMO the hairspray would help with adhesion also. Zero dust on the wood is mostly likely the best thing you can do.

Yes. I use compressed air to thoroughly blow the dust from the surfaces and then wipe with a tack rag that can be bought from an auto paint supply store. If you have a layer of balsa dust between the surface of the plane and the covering, it will not stick. Get that puppy clean and the covering will adhere well to the balsa.

I'm a fan of hairspray. I vacuum my pieces, then spray a light coat. It will raise the grain a little, but I've never been able to see it in the finished job. It definitely helps with adhesion PROVIDED you let it dry fully.
