Clearcoating Epoxy Resin
1 Attachment(s)
I put together a field box and coated it with Great Planes Pro Epoxy finishing resin and after seeing the finish of the wood I just can't paint over it .I'd like to protect the finish by clearcoating over the resin.What kind of clearcoat would I use on it ?Would automotive type work or something like Krylon Crystal clear?

Polyurethane.. Comes in Gloss or Satin - your choice

nice job. Why would you want to clear coat the epoxy? The clear coat will not be nearly as durable as the epoxy finish you now have. Finishing epoxy is used extensively in homebuilt boats and is left as is. You would have to sand the epoxy to insure that the clear coat would adhere. I think is more money and bother and not necessary. Just my opinion.

I noticed that the hardened resin scratches very easily and thought that the clearcoat would with stand mild scratching.There's two coats of resin on it and very smooth.I also build wood hull boats and coat with resin to seal the wood,but prime and paint over it ,then clearcoat the final paint. Protects it from mild scratching ,but won't withstand a major hit.

Your epoxy coating you now have is much more durable than any finish coat you will apply.

I enjoy boats also. Yes, if you are making a scale hydro you will paint it for sure. Actually a scale any boat. Painting it would certainly personalize it so COOL do it. Might I suggest that before you paint it print up a label with you name, address, phone, E-mail, AMA # whatever and epoxy it into the box somewhere, paint it but tape over your label. It might deter theft and assist in recovery if lost. Just a thought.

RE: Clearcoating Epoxy Resin
Epoxy resin should not be left uncoated when it will be exposed to sunlight. It suffers actinic degradation i.e. it breaks down due to the action of the ultra violet component in natural light.
When used in marine applications (I've done a lot with full size boats) it is over coated with polyurethane varnish which includes elements which suppress UV degradation (usually cobalt based). If you don't overcoat it, it will yellow and age quickly. Cured epoxy should also be wiped down with acetone or white spirit to remove the waxy deposit which is exuded onto the surface as it cures. This 'amine blush' as it is called, will prevent proper adhesion of the varnish unless it is removed. I've used 'West epoxy' extensively in the restoration of sailing boats, and also use it to fuelproof the firewall areas and engine bays of my models. |
