Blow drier for Epoxy.

I haven't seen it mentioned here before, ( but I haven't read ALL the posts), of using your hair drier to move epoxy around.

I've built R/C race boats for years and one of the ways to coat the plywood insides and out and get good coverage, I use a blow drier.

You mix the epoxy as instructed, apply with a roller or brush, and then to get it into all the nooks and crannies, the blow drier will do the trick.

As the epoxy gets warm it becomes less viscous and will flow or move to where you blow it. You can use an old credit card as a squeegee to further spread it. You end up with a thin,smooth coating. Almost like a varnish or shellac.

If you want a thicker covering you continue to add coats, till you get the desired thickness. Then you can wet sand , etc. before painting if its an exterior side or leave it alone if it's an interior surface.

It does speed up the curing time, you can't blow it around indefinitely but it helps if you want to use less material and cover more surface, or be sure it got into all the little imperfections.

Working with wood, anything which speeds up the curing time is going to prevent the epoxy from going into all the imperfections you'd like it to get to

I've built wooden boats using epoxy for years and have never heard of anyone advocating speeding up the curing time - We usually do the opposite . . . . use very slow cure hardner so that it takes 18 to 24 hours to cure - That will allow the epoxy to penetrate the wood and give you the best bonds
