Chestnut Posted December 19, 2019 Report Share Posted December 19, 2019 I needed to spray one of those game boards I make. I didn't want to lug in the HVLP for 1 board and make a mess of the shop so I figured I'd just use the rattle can version and knock it out fast. WRONG. The stuff in the aerosol can is awful. I spent more time trying to get enough down to flatten out than it would have taken me to brush on from the can. If I didn't lay down a heavy coat the surface finish would have looked like 60 grit sand paper. I don't want to give a complete don't buy because it has it's place. It is still marginally easier than digging out my HVLP and spray proofing my shop though. The over spray from the can is less than from the HVLP so i guess it could be used in tighter quarters. Has any one had good luck with any aerosol polyurethane? Quote Link to comment Share on other sites More sharing options...
wtnhighlander Posted December 19, 2019 Report Share Posted December 19, 2019 Nope. Deft lacquer is pretty good, and Krylon (or was it Rustoleum?) clear acrylic spray goes on nice, but looks a bit more plastic. Because it is. Quote Link to comment Share on other sites More sharing options...
Tom King Posted December 19, 2019 Report Share Posted December 19, 2019 Do they sell it in solvent based? Modern solvent based spray paint works amazingly nicely. I wouldn't spray it in the house though. Water based is just too finicky to get all the planets aligned correctly for it to come out good from a spray can. I bought a can of Ace Hardware brand to paint (solvent) a John Deere fuel tank, after we fixed a leak in it, and the paint job looked like it came out of a factory. I couldn't have done better with my best gun. I just bought the Ace can because it wasn't that important to me to get a top quality paint job, and they are close. I probably would have bought a name brand, if they had it in John Deere green, but they didn't. Quote Link to comment Share on other sites More sharing options...
pkinneb Posted December 19, 2019 Report Share Posted December 19, 2019 As @wtnhighlander pointed out above I've had good luck with this, its my go to for need it quick or small stuff https://www.amazon.com/gp/product/B000ZYWE00/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1 Quote Link to comment Share on other sites More sharing options...
Tom King Posted December 19, 2019 Report Share Posted December 19, 2019 Thanks for posting that. I haven't seen anything with the Deft brand on it for Years. I used some sort of spray can lacquer that worked good too, but not sure of the brand. It might have even been Minwax. I think it came from Home Depot.

Chestnut Posted December 19, 2019 Author Report Share Posted December 19, 2019 Yeah spaying indoors so solvent is out unfortunately. I can't spray outside as its like 8F. I lugged the hvlp in from the shed. I'll just have to do it this way. Maybe i had a defective can. I'll see if i can return it. After it dried the surface finish was garbage and I'll have to sand it off. Quote Link to comment Share on other sites More sharing options...
SawDustB Posted December 19, 2019 Report Share Posted December 19, 2019 I've tried it a couple of times and had very mediocre results. Spray shellac works great, as does lacquer from a spray can. I think the poly gums up the inside of the nozzle almost instantly. I always find it's uneven and sprays the occasional blob of finish. I just brush instead.

I just brush instead. With all the little dimples in the board it's really really hard to brush. Each spot grabs a bunch of finish off the brush and causes a buildup in the hole. Shellac is a great idea as is lacquer, I'm also not sure how well they'll hold up over time with it being a heavy use item like a board game.

SawDustB Posted December 19, 2019 Report Share Posted December 19, 2019 I can see the problem. I usually only use that kind of finish on decorative things like picture frames. I have wiped on the water based finish before with good results, but spraying would be easier. Quote Link to comment Share on other sites More sharing options...
wtnhighlander Posted December 19, 2019 Report Share Posted December 19, 2019 I'd use butcher block finish...oil & wax. Quote Link to comment Share on other sites More sharing options...

Yeah that doesn't sound like it hold up to random alcoholic beverages being spilled on it. It'd be easy for me to refresh but I'm not the end user. The people i sell these too use them camping and outside so i need a finish pretty bullet proof. Quote Link to comment Share on other sites More sharing options...
KenP Posted December 22, 2019 Report Share Posted December 22, 2019 I wish I would have read this post ealier...I'm making picture frames for xmas and also a first project and used varathane water based poly. Most of the frames worked well, but my purple heart frames might be dead. Has anyone in here experienced this weird green color in the grain after finishing...I'm very much a noob so maybe there is some weird chemistry with purple heart that I'm not aware of. Please give me some.of your thoughts. Happy woodworking everyone. Quote Link to comment Share on other sites More sharing options...
wtnhighlander Posted December 22, 2019 Report Share Posted December 22, 2019 Water-borne poly typically has a clear to slightly blue-ish tint. Hard to imagine that green could show from purple just as a color mix. Purpleheart is an oily wood, maybe there is a bit of chemical reaction?

Must be some sort of reaction, I did notice the bluish tints as I sprayed. I'm hoping sanding will remove most of the blue green but oh well. My family won't say out loud that its ugly as hell....haha...the best part about this is it's a learning experience. Cant get better if I don't mess up along the way. 1 Quote Link to comment Share on other sites More sharing options...

Tpt life Posted December 22, 2019 Report Share Posted December 22, 2019 A few thoughts... I don’t have experience with Purple Heart, but many tropical woods like it have yellowish material left by dried sap. Blue and yellow make green. Purple Heart does not stay purple. It turns brown with time. Did you know this? Just FYI as the color may not stay greenish. I think this might be a good case for shellac as a barrier coat. Try a sample with shellac on it first and see if you like it. Finally, since Steve is not here to say it himself...it is good practice to keep some off cuts from your project, on which to test your whole finish schedule.

Said so well I will just say see above and move on PS I have worked with PH but the above post is still right on in my opinion. FWIW I test any new finish/wood combination on scrap period. To much time making pieces to ruin it by not doing a quick test. Quote Link to comment Share on other sites More sharing options...
Tom King Posted December 22, 2019 Report Share Posted December 22, 2019 It should scrape off fairly easily with a cabinet scraper, or just wait for it to change. Quote Link to comment Share on other sites More sharing options...

Got plenty of off cuts...that's a great idea I'll test more finishes. Hopefully they go well. Thanks for the advice. 1 Quote Link to comment Share on other sites More sharing options...
marshalltjones Posted January 29, 2020 Report Share Posted January 29, 2020 Purpleheart is very resin rich. You may also try rubbing down the PH with denatured alcohol or acetone before finishing. Quote Link to comment Share on other sites More sharing options...
