Epoxy Barrier Coat on my typhoon

[Jay B]

I bought a typhoon recently and while there are no swollen blisters, there are spots all over the bottom of the boat where the gel-coat has peeled off in a blister sort of shape. They are completely dry.
So i have scraped and sanded all of the bottom paint off and I am down to the white gelcoat. I am going to use the Interlux Interprotect 2000 system to barrier coat the bottom. The boat is sitting on a trailer and there is no way to sand and seal the bottom of the keel. Does anyone know if that is going to be a problem? Will water get underneath my new epoxy job and cause me even bigger problems?

Your note is a little confusing. You indicated that the gel-coat has pealed off and you have taken off all of the bottom paint down to the white gel coat. I think you will need to repair those patches where the gel-coat has pealed off and then apply the Interprotect. If I were you I would get the boat off the trailer and get the keel done. Give me a call if you want to discuss 212-493-2850. I have some ideas on how to do this.

Jay: I also took all the paint of my Ty and barrier coated the hull as a preventive measure against gell coat blistering. The Ty was also sitting on a trailer. By jacking up the boat,then lowering it onto raised wood blocks you will be able to coat under the keel.When this has dried, reposition the blocks and complete the bottom of the keel.Then work up to the water line to complete the job.

How did you jack up the boat? I was told that the boats weight should always be on the keel. I suppose I could rotate the support pads up on the triad trailer until the keel is exposed. Will that damage the hull? What type of epoxy did you use? Because of MIN/MAX hours between recoats, how do you move the boat back and forth so you can get under the keel and under the support pads while building coats?

Thanks for your reply

Sorry i did'nt get back to you right away Jay, was out of town on business.
The boat originaly was on wood blocks, and moved on to a Triad Trailer by a combination of using a car jack ( the type that is used at your local garage),wood blocks,and boat jacks (small and large). The boat was raised up approx 20 inches with the boat jacks and the trailer moved in under the boat.A combination of blocks and repositioning of the boat jacks and wolla! she was in place.The process took a few hrs and some brain scratching It was then just a matter of lowering the boat on to the trailer. I see no problem on using the screwpads to raise the boat up of the trailer. Then lowering back down onto a small block fore and aft under the keel. The material that i used was Interlux Inter Protect 2000E a two part formula ,easy to mix and apply. By the time I rolled the whole hull it was already dry where I started I finished the job in one day,allowing 4 hrs between each coat, giving the boat 3 coats. The next day i moved the blocks and did the rest that i was unable to get to. Hope this helps, Bob P
PS; by cutting 4 2x4's and jambing them under the rub rail,or setting up a fore and aft support the boat will not tip over when the pads are backed of from the hull as all your weight is down on the wide bottom keel.

Jay-I have had my Ty lifted with a forklift several times without any problems. The forks positioned about a foot on either side of the keel.
