What adhesive to use on rub rails?

[Juker008]

Hello everyone. I wanted to ask you guys what you recommended for me to use on the rub rails on my RIB; 15' Novurania. The rail seems to be coming off of the bladders, and it seems to me that they were originally put on with Shore adhesive. Should I just use Shore adhesive; simply put more on and glue together? Do I need to remove the old existing stuff? Is there another product that you guys would recommend?

MTIA,

You will need a 2 part contact adhesive. Bostik 2402 or it's yankee cousin.

make sure you prep it right.

Since you didn't say what your tubes are made of, the Weaver universal stuff should work. P/N 3001 (listed as for PVC, but works on both.) If they are hypalon tubes, any hypalon adhesive should work as well (Clifton, Shore, Weaver, Bostik, etc.)

Yes, you should clean the old adhesive off, if possible. Gentle power sanding may do it (if it's a large area); hand sanding would be my preference (for smaller areas.) Solvent (MEK for hypalon) may help to soften the old glue a bit. Make sure you only remove the old glue and lightly rough up the hypalon surface. Do not sand down through the hypalon to the fabric layer. Roughen up the rub rail in the same way. Degrease and clean with an MEK moistened rag (both types of fabric.)

Follow directions for the adhesive of choice to the letter (generally, two or three thin coats, with drying time between, allow last coat to tack up, and apply as much pressure as you can get on the join for a day or so.)


A Google search for Hypalon repair (or PVC boat repair if your tubes are PVC) should get you more detailed instructions, as well as adhesive sources.

Luck;

Universal glue does not work as well as specialist glue
Two part works a lot better than single part

Rogue: While I agree with you to an extent, you also have to take into account that you are not gluing hypalon to hypalon (or hypalon to neoprene, as is usually the case when gluing material to material.)

The rub rail is likely an extruded plastic (EPDM?), and likely contains oils that will derate the bond. A urethane based chloroprene adhesive will work quite well for this, as it's designed to bond to quite a few different substrates.

EPDM or rubber use hypalon/neoprene glue ,Pvc use PVC glue
