Being a old car painter. Tape the glue surfaces and try the HLVP gun. If does not come out of the gun, its taped up for fast brush work.

if your trying to spray regular epoxy all i can say is good luck if its cpes your probably going to want to use a full face respirator i would not want the stuff getting in my eyes all so you better suit up and wear a head sock or youll be nice and shinny for a while

Thanks Red. I did get a full paint suit with a hood. New 3M respirator. I will move lots of air and let you know.

I did mine a different way.

Once I flipped the hull, I used 2 coats of CPES (brushed) on the entire interior.
I then sprayed marine varnish over the entire interior to seal the wood.

My reasoning: Standard epoxy is not very flexible - even though the hull is very stiff - I suspect microfractures could occur and then water can get under regular hard epoxy. CPES gets absorbed into the wood for sealing it, the varnish protects the CPES.

Boat is trailered and covered, but I have no water intrusion issues. I bet you would use less CPES than epoxy, and would be more likely to get it to flow into any small gaps.

After you plank the hull, you are going to want to seal the planking anyway. Are you doing the same work twice by spraying before planking?

At the speed my Poxy Shield set up, I wouldn't dream of spraying it. Trying to clean out the HVLP gun, nozzle, etc..., fast enough..., :shock: gives me chills thinking about it.

Besides, you'd have to thin it, and that seems counter intuitive to what you want to accomplish when encapsulating.

That's just me...

That's what we did to the inside of the hull after we flipped our build. We used a Riobi airless sprayer and thinned the Epoxy Shield with denatured alcohol. Full Tyvek bunny suit, gloves and full respirator face mask a must. Worked great and able to get on a few successive coats while the previous coat was still green.

I did use poxysheild, I did cut it, maybe 10 percent with laquer thinner. Sprayed well. The garage was pretty cool during application, having door open for ventilation. With the slow poxysheild and cool temps I had plenty of work time. The gun blew clean, no problems.
