Posted: Wed May 04, 2022 10:53 am Post subject: Hatch cover adhesive compatibility |
|
|
I am planning to replace the original (leaky) hatch covers and trying to decide which adhesive/sealant to use. Already purchased the IMTRA 4000 series covers (part# SPA-40155) and noticed the instructions say to use ONLY silicone based caulking compounds.
I was planning to use either butyl tape or 3M 4000. Am I setting myself up for compatibility issues with the plastic hatch material?
Cheers,
-Dan |

I replaced my original hatches with the Imtra ones. I used either 3M 5200 or 4000 (can't remember). I've had no problems with the hatches.
Only caution I would mention is that the Imtra hatches can be damaged by solvents (e.g. acetone) so if you are using a solvent to clean up the adhesive, be careful of getting it on the hatches. I did not notice this issue with the original hatches. |

This is an application for Boat Life Life Seal, which is a blend of silicone and urethane. One of the few sealants which works well for various plastics and fiberglass.
Quote: | Use for sealing decks to hulls, thru-hull fittings, vinyl ports, sealing/glazing windshields and bedding marine hardware. Will adhere to metal, glass, wood, Lexan®, ABS® and certain other materials. Can be removed without damaging gel-coat. |

Dan,
For applications above the water, I use butyl rubber (white 1/8", 3/4" wide) it sticks to itself and rolls like silly putty. No chemicals to damage your skin and easy clean-up. It stays pliable longer than most other, off the shelf products. Tech tip: put the hatch in place, place painters tape around the hatch, put butyl rubber tape to the backside of the hatch, tighten the hatch down uniform but not rock tight, wait a day for the putty to squeeze out, remove the tape. Any final cleanup, use denatured alcohol to wipe the edge.
Job done and no more leaks. Hinckley Yachts uses this magic stuff and has for years with very good results. The product is inexpensive and is available on eBay, Amazon or other sites. _________________ Steve Baum

With one vote for 3M, one vote for Boat Life, and one vote for Butyl Tape, it sounds like I can't go wrong! haha
Cheers,
