Looking for some guidance. I am very happy with the finish I get from General Finishes Arm-R-Seal wipe on Gloss. I typically put on 4-5 coats. Unfortunately, its a 12-18 hour dry time depending on the humidity here between coats.

I need to get the same look and feel in an 8 hour day start to finish. Is this even possible? Any recommendations?

You’re going to have to look into commercial spray finishes. There’s a lacquer or conversion varnish out there that will do what you want. If you really want speed, get an expensive airless, air-assisted pump and gun so you can spray high solids finish without thinning.

With good surface prep, I can get a nice finish with two coats right off the gun. The main product I use is Sherwin Williams precat lacquer.

Water based finishes (I like Deft water based clear acrylic) might work for you. Dry to touch in about 20 minutes, recoat in a couple of hours. Light sanding between coats.

There are also water based urethanes, but I haven’t used them.

Precat lacquer is great stuff if you can deal with the explosive fumes, and it can be thinned as needed such that about any cheap spray gun can be used. WB urethane finishes dry to the touch faster and can be built up in one day, but takes about the same amount of time as OB poly to actually cure out for final rub out/finish. I use Target EM9000, and the instructions state 120 hr cure. The longer the better if going for a fully filled gloss finish like a table top. I typically use satin. Except for a top, 2-3 sprayed coats are fine, and can be done in ~3-4 hours. I also really like EM6000, a lacquer, and mostly use it except for tops. WB finishes require a better gun to atomize the finish – WB finishes are limited to ~10% thinning. They can be brushed, but not advisable on large surfaces.

WB finishes look lifeless. 2 things that really help them – a coat of shellac before the WB finish will add chatoyance, and Transtint dye can be added directly to get the same color as OB poly.

Becikeja, I also really like Target’s EM6000, unlike OSU, I do use it for tops. I have found that the addition of 5-10% CL100 make an extremely durable top coat. Use the cross linker for 2-3 coats for the best results. HTH

I currently do not have a HVLP sprayer. Sounds like that’s necessary for some of these? I appreciate the input.

You can lay down a LOT of coats of wipe on poly in a day… at least 4-6 easily as they will dry to the touch in 15-30 minutes, ready for another coat. Then just let it sit overnight for final cure. Certainly less time than 4-5 coats with 12 hour wait times between them!

Cheers,
Brad

Overnight for ob poly to “dry”, Flash off all the solvents. However even with a thin coat it would take a week to actually cure, and more coats and more humidity extend the actual cure time. It takes time for it to fully combine with oxygen.

Water base, shellac or lacquer are what come to mind. I think I’d go with the lacquer. Last time I used it, I had Sherwin Williams Dull Rubbed Effects Lacquer and sprayed it on with a small gravity gun from Harbor Freight. Took me a bit to get the gun ‘tuned in’, but worked great after that.

Still, 8 hours is not much time to go from sanded wood to final finish.
