Sealant for hatch window

[AleCiotti]

Hi guys i will be replacing the sealant that connects the my hatch frame to its glass (it's made of plastic).

Since I'm in Italy and can't get my hands on Dow 795, what can I use instead for the job?

Thanks in advance!

What specific hatch[manufacturer make/model], and 'plastic' lens material?

In addition to Dow 795, I’ve seen [depending upon the specific frame & plastic]:
Dow 995
Sikaflex 295 UV, with the special primer.
3M 4000 UV
GE SSG4000

Hi Gord!

I don't really know the model/manufacturer, but the materials are metal (stainless steel I think) and rigid plastic.

I need to reseal the two pieces of the hatch together basically

I linked an image that showing the sealant I'm looking for.

Thanks 😁

Hi...

I ve just resealed my hatches. In my case, the "plastic" is polypropilene and the metal of the hatch aluminum anodized. ("plastic could also be acrylic, check that out!).

I have used Sika 295 but without Primer. (I ordered the 295 from Amazon but the Primer cannot be shipping overseas by plane due high flame risk, but the Sika 295 is ok to fly). By the way, if your order from Italy to Amazon, you may well order the Dow 795 if you are used to it)

And the way to do it is to clean the aluminum of the hatch with Alcohol Isopropilic , sand it with 180gr...clean it again until super clean with the rubbing alcohol and apply the Sika hoping the sanded surface is enough to grab the seal...

In my case, after a month or so, my three hatches looks great and behave normal. No problem at all!

I hope this might help!

Thanks ��

Surely that is a Lewmar Ocean Hatch? (The same model hatch that Dockhead has on his yacht)


What are Lewmar thinking - $A1697 in Australia.

Thank you for your answer! unfortunately I've check all over the internet and I can't seem to get the dow 795 shipped here, I will check-out the Sika 295 and it's primer.

Thanks again for the answer!

[AleCiotti]

By the way, is there a way to clean the "plastic" so that it doesn't look so bad?
Thanks!

[Dymaxion]

Cleaning up the plastic: car headlight restorer, Brasso/Silvo, or even toothpaste. Apply as per restorers instructions, otherwise apply and buff hard. Best to test on a small section first. Won't likely be "as new" just better a bit.

[NevilleCat]

You should be able to get Fixtech FS 200 for your sealant/adhesive in Italy I would think, as it is made in Belgium. Doesn't require a primer like 295

That is in really rough shape. Just replace it. It is acrylic. NOT polypropylene as somebody suggested. Given the old one as a template any plastic shop should be able to make one. It will vastly improve the look of the boat.

Unfortunately, the Lewmar Ocean lens and gasket are not serviceable, the entire lid assembly has to be replaced. The replacements seem expensive but do come with new handles and hinge gaskets which often leak as well.

Ok, I will try to take it off and see if the problem is the sealant between the hatch and the wood, if that's not the case I'll check the gasket and the hatch itself if it has any damages that let's the water in.

Thanks!
