Balsa sealant?

Recommended Posts

I often use slightly thinned Devcon Two Ton epoxy but there are choices as long as the coating is durable, hard, and waterproof.

I've used polyurethane, minwax wood hardener and spar urethane on cedar wood.  They all do a decent job.  For a real smooth painting surface though, a layer of epoxy (or superglue) seems to work best.   But, I've never used balsa.

I like runny super glue for balsa, because in penetrates into the wood on the first coat, so a two coat deal makes the softer balsa's surface much harder.

Propionate works well but it has some downsides.  First, it’s hard to find prop pellets for sale.  A couple of TUers sold it years ago but not any more.  Prop needs to be dissolved in acetone, onto a fairly thin solution.  Then the lure needs to be dipped anywhere from 5 to 8 times to build a sufficient coating thickness, with pauses between dips to allow the acetone to flash off.  Afterwards, you should let the coating sit overnight to fully harden.  So it’s a rather labor intensive coating compared to most other options. But it does make a nice undercoating.  If you are building a batch of 5-6 lures, you can dip lures almost continuously.

All I do is put 2 coates of  heavy polyurethane and then sand it smooth.  Tis just keeps the paint from soaking down into the balsa and fading your colors. If you clearcoat with epoxy then this is about as good that it is going to get. Sanding a bait sealed with super glue or epoxy to get it ready for paint can be a lot of work. However it does seal the bait well. If you really want to make a balsa bait bulletproof then clearcoat the bait with epoxy, paint it, then clearcoat again. Lacquer will stick well to epoxy.

Hey Skeeter, do you have a preference between oil or water based poly? Do you cut it with anything?  I see some makers on youtube using poly and recently bought some for myself to try as well.  I'm not to worried about dry times as I just let my stuff hang overnight.

I just use gloss Minwax polyurethane. In a pint can.  If it gets too old or not seald back correctly it spoils.
