AN UPDATED VIDEO HAS BEEN UPLOADED A question I get most asked is "how do I apply gelcoat" while the answer is never a quick or short one, I decided to make a very quick how to video explaining how to get the first layer of gel on your boat.
Updated video- • How to apply gelcoat ...
In this video I show how to apply the gelcoat over a semi set layer of fiberglass and polyester resin ( of course its totalboat stuff ) Here I use a roller and a cheap chip brush. My preferred method is spraying the gelcoat, but this is the best method for something we're just going to sand later. In a video to come ill show my method for applying laminating gelcoat, with one final layer of waxed gelcoat. Thanks for watching, don't forget to subscribe!! Oh and use those discount codes.

I found using a hvlp spray gun with a 2.5mm tip. And also using a patch booster from fiber glass supply for the gel at %25-%30 works the best and following directions works great

@user-to6wy8ql2g Жыл бұрын

this is a straight forward common sense video. important part of the video is explaining how to mix 2%,and clarifying if you're using waxed or unwaxed gelcoat. It was confusing because you say you're going to use the laminating gelcoat next. I understand laminating gelcoat as unwaxed that goes down before adding waxed gelcoat you cure. so, if you're going to use laminating gelcoat next as you say, then the layer you demonstrated must have been waxed which is opposite of what I understand. I more confused than ever by this video.

@HoldFastMarine Жыл бұрын

Ok you didn’t really pay attention. I read the can in the video, gelcoat with wax. You use gelcoat with wax to cure laminating poly resin. You have to cure the resin before you begin fairing, which is the next step after the gelcoat cures. The laminating gelcoat is to get a thicker surface so when I sand pre buffing I don’t sand through and destroy all my hard work.

@donniemunroe7512 Жыл бұрын

can you gelcoat over poly resen right after its layed, or do you have to wait for some period of time ??

@HoldFastMarine Жыл бұрын

You have to at least wait for the gelcoat to set up. For small areas probably a few hours. Larger areas I’d wait 4. You don’t want an excessive buildup of heat. Sometimes I will go right over fresh resin BUT only when I have to. I’ve been doing this so long I know when and when not to do it. I don’t recommend that approach for a novice. Merry Christmas

Can you apply multiple coats, of Gelcoat with wax? Do you have to remove the wax for the next layer? Does sanding (wet or dry) that layer it cause wax to melt and need to be removed by dewaxer?

@HoldFastMarine Жыл бұрын

Yes you can, but you need to sand between coats. Don’t think of the wax like a candle wax or car wax. It’s just an additive. Sand with 180 between coats, once it’s dry.

@HoldFastMarine 2 жыл бұрын

They don’t advise against it, I think it’s intimidating for people. Pot life for paint is 3+ hours. Pot life for gelcoat is 10-15 minutes.

I am about to do a Whaler 13’ with gelcoat with wax. I have 3 pints. I’m planning to use a pint per coat, sanding in between as you mentioned. How should I plan around the short pot life? Do you catalyze, spray, clean gun….then repeat? I am thinking two 8oz batches per coat. Is that ok to stop mid spray and reset?

@larryflorida5695 3 ай бұрын

A bit unclear and not sure if you're using the right products. Filler is used to fill holes, epoxy if structural. Perhaps a layer of fliberglass resin might be a better choice than gelcoat. The gelcoat is your finishing product. Am I correct?

@HoldFastMarine 3 ай бұрын

I’m confused by your question. But I’ll try. I never use epoxy resin. The gelcoat contains wax, which fully cures everything below it, ie the resin without wax. Also finishing with gelcoat helps fill in the glass mat and gives you a smoother finish for fairing.

@larryflorida5695 3 ай бұрын

@@HoldFastMarine Maybe I'm confused, but sure looks like your NOT finishing, but cleaning up a rough surface, and looks pretty rough, and not sure if the surface was structurally compromised, but looks iffy. that's why I'd use Epoxy, and perhaps some cloth to help smooth out the rough spots. After which I'd sand it, clean it, touch up with filler to fill spots or voids, and THEN go to the gel coat which would be the last product.

@HoldFastMarine 3 ай бұрын

I’m not finishing, nor am I finishing a rough surface. I’m curing the resin with the gelcoat. You say that you would do all this work with epoxy and then do your gelcoat. Gelcoat does not stick to epoxy. But you go and do things how you wanna do them. I do things the way that I wanna do them.
