Tacky Hotcoat (UV Cure)

Like I said you do it your way, I’ll do it the way I’ve done it since the 90’s with never a tacky hotcoat.  I’ve never had to look it up because I have never had a bad result.  Always did the way I was instructed to do it with good results .   Asking me to link something is like asking BillT to post pics.  The Solar Rez video was found by accident and viewed once.  You go ahead do it you way.  You’re welcome to taking it personal.  That’s your thing not mine.  Funny.  There doesn’t appear to be any artificial light in the SolarRez shop.  All UV tarps with gaps etc.

You should learn to admit when you’re wrong.  Doubling down in the face of glaring evidence isn’t a good look.

To the original poster;  You tried it the way marko & verbal voiced and did not get a sandable hotcoat.  You’ve got nothing to lose by walking it out in direct sunlight for a count of ten next time.  If my method doesn’t work you’re not any worse off.  If you rehotcoat this board using MEK in a normal dose, it will be sandable.  Give it a try.  Like I said;  Ten seconds in UV won’t make things any worse compared to what you’ve got now.

Just be sure to wait five minutes to let the wax rise to the top as both Solarez and Surfsource advise.  Don’t listen to bad info.  Seek out the manufacturer.  Do not…I repeat…do not immediately take it out in the sun after brushing it out.  LOL!

Shark man, I tell you, The Ding is King!!! 

We all shall bow! The Ding knows all! 

Get out your straws and blow! (Ha!)

Repeat after me. The Ding is King! The Ding knows all! 

Haha!  If I wanted a gummy mess.  I’d wait five minutes.  Lol!  If I were wrong I’d admit it.  There wasn’t any internet or YouTube for surfboard builders when I learned to do this shit.  Unlike you, I got my lessons from people who did it for a living and knew what they were doing.

Ok.  If you say so;  “The Ding is King”.  Lol out your a$$.  Haha

SolarRez buys Silmar and repackages it with UV powder from suppliers like Duratek.  So who is the manufacturer?  SolarRez doesn’t manufacture anything.  They repackage.

 

 

To the original poster:

1.  Make sure you are adding wax solution and not styrene.  Make sure your wax solution hasn’t separated or the wax solidified.   Also, I’ve gotten wax additive from different suppliers that was drastically different    Some thick and oily and the one I prefer that is thin like water   Follow the ratios on the instructions  

2.  Make sure you are adding the right amount of wax solution.

3.  If you are buying pre-mixed sanding resin be sure to shake the hell out of the can.  (You also could have a can that wasn’t given the right amound of wax solution or got mislabled)   If you don’t shake the can prior to each use you could get completely different results throughout the life of the can   

4.  Brush it on quickly and evenly, cross brush it out and give it a quick nose to tail and walk away.  Overbrushing will brush the rising wax right off of the board.

5.  Wait a few minutes to let the wax rise (exactly as both Surfsource and Solarez recommend) and take it into the sun.  I’ve always done five minutes and have never had a sticky hot coat or gloss.  If its blazing mid-day sun go in and out of some shade to slow down the reaction.

6.  Be careful of bad information on the web.  When in doubt check with the maker of the product you are using.

 

Cheers.

Let’s please not do this.   Stick to the subject.   Our interests are in what does/doesn’t work, and everyone knows there is often more than one solution.  If you’re going to express your disagreement with an opinion then stick to the content itself, not the individual expressing it.   

I was talking about that very possible one problem was the lack of the right amount of wax; I mentioned that no matter if the resin has the UV powder if you do not have the wax always be tacky.

Regarding let the wax rise or the other way around; both work however, is safier let the rise wax for a moment then go to the oven. That is the way almost all the big factories do; they not brush the hot coat then go to the oven then remove the board to the rack again then go again to the oven…

I dunno what this adds to the discussion but I’ll throw it out anyway.  Submitted for your consideration.    

 

I forgot about this vid until just a few minutes ago, but it’s an instructional from Wahoo Int’l (Solarez) showing how to use their product for a finish coat (on an agave board, no less).   In it, the glasser (Mike Richardson) shows leaving the board sit for 1/2 hour after laying resin to let it flow.   At 6:00 in he shows a 3-stage exposure to cure it, starting with an 8-second exposure to get the exposure going, a second exposure to get the resin to the B stage so he can pull tape and such, and then a final exposure.   

I distinctly remember Gary from Wahoo telling me to do the same several years earlier.    

The vid was done in Oceanside (I believe) so the latitude and UV will be a bit different than in other locations.

Obviously not the only way to use the resin, but it is one way.   

 

Hey thanks for everyone’s (very passionate) replies. I ended up giving it a couple of days to cure more, and eventually got it to a point where it was sandable and was able to sand it like normal.

I did a bit of small scale testing with my resin and came to the conclusion that I didn’t shake hard enough and needed to really shake the shit out of my resin jug to get good results. I was able to get a full cure using both methods (expose for 10 sec and then bring back into shade and wait 5 min for wax to rise then expose), but these were small areas of resin so a full board hotcoat could shake out differently.
