Problem - and solution?

[caribmon]

Scenario...

First layer of cloth and vinylester about to go on below-the-waterline foam... strongback straight, good start.....

Problem.

Builder has never used vinylester before, runs no tests, and lays up glass.

Vinylester does not set (no cobalt for a start). His supplier gave him shoddy directions on the use.

In a panic, builder starts spraying activator directly on with spray bottles. Still soft....

Solution of builder is to lay a coat of polyester resin over soft uncured two day old vinylester resin and cloth.

It finally hardens.

Finishes job with Vinyester over Poly.

How long do you think it will take before the skin pops from the foam?

I give it three years tops. Could happen anytime in rough weather. This is an 'offshore' boat.

Opines?

The solution is to quit pouring good money into a bad boat. The first layer of vinylester never hardened. Mistakes happen, about the only thing there is left to learn from this one is when to quit. Sam

I give it two, maybe three months if it's being used offshore like that.

When something goes this bad, there comes a point where you have to scrap it and start fresh. The resin was mixed wrong, it didn't set, so there's essentially no core/skin bond. This hull is probably not safe to take out on the water.

You can take a coupon and make a delamination test.

Try testing it against a properly done panel as a control
