Default Attaching Velcro to wood parts

Do you apply a thin layer of epoxy to the wood surfaces and let it set before attaching the hook and loop material to improve adhesion ? Does this really help?

I normally stick the hook side on the fuselage and the smooth side on the battery . Is there a preferred way ?

Tks

Letting the epoxy set for any length of time will actually weaken a joint. If you use epoxy, put the parts together as soon as possible so the epoxy can actually bond to the parts

I use Medium CA on the velcro itself and scuff the wood up a little up a little with 80 grit

I take medium CA and rub it into the wood with a gloved finger. Just about anything that would seal the wood will work. Ca, Epoxy resin, polyester resin, polyurethane or even clear finger nail polish would all work. CA is obviously the fastest.

I like to use contact cement on both the mounting surface and the hook and loop.
Makes a good perminant bond.

I have had a tough time getting velcro to stick to Lipo batteries. It's been mostly the glue letting go of the velcro, but occasionally too not sticking to the plastic battery pack. What kind of velcro do you guys find works well?
I've tried using epoxy, gorilla glue, and CA. Surprisingly, CA has worked the best for me after scuffing the battery pack with some 120 grit. I use medium and let it cure for a minute before hitting it with kicker. I find that minimizes the expansion that kicker causes.

Jester, are you using the self adhesive Velcro?

I've been using Velcro USA brand. Some that claims to be industrial strength with adhesive back. On batteries I use only the adhesive it comes with. Clean the battery mounting area good and clip the points off the corners of the Velcro helps alot.

I've used self-adhesive and non also. I have found the self-adhesive to stick reasonably well to batteries, better if I scuff them first. But it eventually peels. I stick it back down with CA when that happens, which buys me a bit more use. I've had the non self-adhesive stuff actually delaminate from the glue, leaving a rough textured layer of glue behind as it pulls off cleanly.

The base material for Velcro is Polyester which is what peel ply is made from so many adhesives will not stick. Something like the E6000 would work well though. I have always used the self adhesive Velcro. Usually clean any non porous surface with Goo Gone and never an issue. As previously stated, seal wood surfaces first.

I have been using industrial grade self adhesive Velcro . The adhesive is very strong but better with either CA or epoxy treatment of wood. I also add a strap to hold battery to tray for extra measure.

Having used most methods the only one that has proven completely foolproof with me is BVM Aeropoxy and that is on any kind of plastic surface or wood. As far as which side you use the hooks and loops on, it does not matter as long as you do the same in every airplane and every battery or electrical device to be secured.
