Ouch! Hotcoat mistake

Got in a big hurry and forgot to add the Styrene surfacing agent to the laminating resin when hotcoating the top of my board. I haven’t made that particular bonehead mistake before. Any corrective advice will be appeciated.

Doug - You can’t sand what you have so would say to just do a new hot coat over the bad one. Though you’ve added a bit of extra weight to the board, it may also be a little stronger now. At least you can tell yourself that to take some of the sting out of your mistake. Pedro P.S. Am a relative newcomer to Swaylocks but after 39 years of surfing a long love affair with surfboards I am enjoying it.

I have made the same mistake a couple of times - to many resin fumes, I suppose. In one case, I covered the hot coat with a sheet of plastic to keep the air out. It hardened but was rough. In another instance involving a smaller area, I gently wet the surface with acetone. It worked but some of the hot coat was lost. The second hotcoat sounds like the best route. Good luck. Patrick

Yeah, I’d put on the second hot coat too. On the up side, you will have plenty to sand into a sweet finish.

Get a new mask dude… Just kidding don’t worrie just make up some hotcoat and use a squeegee and lay a thin coat over the whole board… It may not be the best hoat coat you ever did but it works fine… Not that i ever forgot to add SA to my resin??? Don’t brush it you will make a heavy board and never sand enough off. http://surfnwsc.com

…I have bought fresh hotcoat resin… …and found that after I hotcoated a top side of a board,the supplier’s helper filled my can with lam resin,ARRRGH!!! …Here’s what I did,I took wax paper and ran it down the length of the board,going from nose to tail.Squeeged it down to give it a bond,let it set for awhile,then came back in a few hours and pulled the paper.The wax from the paper leached into the lam coat,and turned it into a hotcoat. …Do this with the board warmed up a bit.Herb

Guys who repair gel coats on boats will spray PVA over the top of the gel coat to get it to cure. This should work. You can get PVA at Crystaliner, Fib Hawaii, Fiberglass Supply, ect… Craig
