Bostick 2402

I am in the process of attaching holding dwon rings with a hypolon circular patch to the deck. My under standing of the directions which I have got on line are
1) sand the deck and wipe off with thinners to make suitable for the patch with ring
2) sand the back of the patch and clean with thinners
3) Paint the bostic 2402 on the rear of the patch and let it go off 12 hrs
4) paint the patch with the 2402 and attach it to the deck and use roller to ensure good contact.

Is my undersatding of the process correct?

TSM

I would do it this way if gluing hypalon to hypalon:

sanding the fabric is just to remove the "shine", and allow access to the materials pores. Don't go too crazy with the sandpaper (or whatever you use.)

12 hours sounds a little long, though I have heard of some people taking up to 24 hours for the initial cure (I don't have that kind of patience.) A half hour between coats should be fine if ambient conditions are favorable.

I usually use 3 thin coats per side; allow the first two to dry pretty much completely (a half hour to an hour), the third gets about 10 minutes. Make sure you get positioning right, as you only get one shot at it.

Use a narrow roller (similar to the edge of a plate) to make sure you get good pressure on the glue bond. Deflate the tube and back it with a solid object (the hull usually works pretty well, otherwise, a piece of lumber will give you something to roll against.)

Luck;

I thought Valiant used PVC tubes? Hypalon glue won't work on them.

In that case, use a couple of layers of PVC glue on the tubes, and hypalon glue on the hypalon patch. The glues will stick to their respective substrates, and will bond to each other.

I might be wrong but I think TSM is proposing gluing the eye to the gelcoat deck - in the same way that you might with footstraps etc?

What gave that away Poly? Was it where he said that was what he was doing?
