hendrix2430 Posted April 28, 2005 Report Share Posted April 28, 2005 Hi, I've finishing a the back of a neck (mahogany) in 3 thin coats of spray on poly (glossy). I've waited 48 hours and the neck is still a little sticky. Is this normal for Poly? Will it go away? I know Nitro takes forever for the sticky feeling to go away, but is normal for Poly to feel a bit sticky at the beginning? Quote Link to comment Share on other sites More sharing options...
erikbojerik Posted April 28, 2005 Report Share Posted April 28, 2005 Give it the sniff test...if you can still smell it, it's not "done". When it gets to the point where you can't smell it, give it the fingernail test...see if you can dent the finish with a fingernail. With poly, if it has cured properly, you shouldn't be able to.

westhemann Posted April 29, 2005 Report Share Posted April 29, 2005 it is normal for any paint to be a bit sticky until it fully cures. 48 hours is not nearly enough.give it at least 2 weeks or you will regret it Quote Link to comment Share on other sites More sharing options...

Automotive clearcoat requires a hardner and you will wait forever on it to dry unless you put enough hardner...... Quote Link to comment Share on other sites More sharing options...
Devon Headen Posted April 30, 2005 Report Share Posted April 30, 2005 Not if it's from a rattlecan. Rattlecan paints are solvent based. By 'paint', Wes meant coating. They are basically synonymous Quote Link to comment Share on other sites More sharing options...
Southpa Posted April 30, 2005 Report Share Posted April 30, 2005 I've used polyurethane clear (hi gloss) in both rattlecan and paintable (well, sponge applicator) forms. I found that the rattlecan stuff dries in the same timeframe, depends on temp/humidity conditions, but naturally an area with good air circulation works best. It also depends on how thick you lay it down. I've learned to take my time and find other things to do between applications. But I generally do about 3 shoots over the course of an hour. I prefer to use the sponge applicator for flat level surfaces. The stuff spreads out like a sheet of glass in one thick coat. Then leave it alone for at least a couple weeks.

Maiden69 Posted April 30, 2005 Report Share Posted April 30, 2005 DEFT is nitro and my neck was painted and after 3 days colrsanded polished and slapped on the body with mo "sticky" feel what so ever. (So the concept that NItro takes for ever to cure is a missconception, it depends how thick and the time between coats you do). I think that you lay the paint to thick, I did this with duplicolor clear and it took months (about 6 ) to get the tacky feel from it.

Devon Headen Posted April 30, 2005 Report Share Posted April 30, 2005 Nope, the Deft is just superfast drying. I've sprayed it and some automotive clear from cans just about at the same time. The deft was rock hard after 2 days, and the automotive clear has just (as of yesterday) gotten hard enough to buff out. That's about forty-some odd days. I didn't adjust my spraying style for the deft, I sprayed it the same if not slightly thicker. Quote Link to comment Share on other sites More sharing options...
Maiden69 Posted April 30, 2005 Report Share Posted April 30, 2005 Nice to know, I will try and shoot the coats heavier to see what happens. But after trying this, I won't go back to Duplicolor. Quote Link to comment Share on other sites More sharing options...
