Engine Room Hatch Insulation Adhesive
|
Paul Stascavage
Good day all.
I am currently in the process of replacing the steel backing plates for the gas strut brackets. It is time to reassemble everything, and I am looking for a recommendation on what type of adhesive I should use to re-glue the insulation to the rubber liner on the underside of the hatch. It appears that Amel originally used a very tacky ‘tar like’ substance during the original install. It also appears that the previous owner used contact cement to re-glue some areas that were failing over the years. I was planning to use contact cement, but I’m not sure if this is the best choice for this application. I would welcome ideas/thoughts from others who have some experience with this.

I have glued back a bit of the insulation that was sagging a couple of times. I found single pack contact cement to be ineffective but two pack neoprene contact cement to work, so far.

Another option could be glue and to screw some battens to clamp it in place…If the insulation I just glued with the two pack fails then I will use some old sail battens to fix it properly… Nick Leros (about to haul out and leave the boat for two months) AML54-019 On 1 Jul 2022, at 16:44, Paul Stascavage via groups.io <pstas2003@...> wrote:

Paul,
The "rubber" liner on the underside of the engine room hatch is actually rubber formulated with a rather high content of powdered lead to help reduce vibrations. Its significant weight makes it very difficult to keep glued to an overhead panel. I think Nick's suggestion of a two part neoprene glue is as good a place to start as any. Most one-part contact cements are going to be challenged with this application. I suspect that Amel might still be using this lead/rubber stuff on the cockpit hatches since it is really the gold standard for sound deadening. Amel SAV might be willing to share what they use. When I was looking at using some of this stuff for another project, the manufacturer specifically recommended NOT to use it in overhead applications because of the difficulty in glueing it down (or is that gluing it "up"?) We are settled in to Port Louis. Thanks for the recommendation. Wish you were here! Bill Kinney SM160, Harmonie Port Louis, Grenada |
