Hello all,
I need to rebed a hatch lens (the Bomar hatch above the saloon). What do you all recommend for adhesive sealant? I believe the hatch is aluminum and the lens is acrylic. Any input would be appreciated!
Dow 795 is an adhesive silicone sealant often recommended for this, and for bonding the fixed portlights along the sides of the cabin top in the salon. A website Sealant Engineering sells a 10.3 ounce tube for ~$6.90 each.
Thank you Jon, I will pick up some of this and give it a go! :thumb:
To avoid confusion, you're talking about resealing the acrylic to the aluminum frame. You're not talking about resealing the aluminum frame to the cabin top. Right?
Yes, there is a leak in between the aluminum frame and the acrylic lens.
Switchback, I had a small leak. I cured it with Captain Tolley's Creeping Crack Cure. You may want to consider trying that before taking it all apart if it's just a small leak. Good luck.
Switch : How about giving us your hull #.
I suspect that you may have a Bomar hatch that is prone to lens leaking - because the adjusting arm is attached to the lens rather than the frame!! So every time the hatch is opened there is stress put on that lens where the adjusting arm attaches and it's transmits the stress to that lens corner where the lens is sealed to the top hatch framing!!
I replaced the entire hatch and would recommend changing to a Lewmar hatch that has a hinge friction adjustment, rather than an arm!
A thought
Hi Ron,
Hull # is 212, thanks!
I'm #206 and my hatch was cast aluminum. I was going to replace it until I found out how much they were $$$$. Stu had done a nice write-up on refinishing his and I followed suit. After removing the existing lense, cleaning and refinishing the frame and hatch, I took it to a local glass place and had them put in new plastic. If I were to do it again, I could probably have done a better job with the sealant using Dow 795 but it didn't cost much. Bedded it with a couple layers of butyl tape and came out beautiful.
Good to know, thanks! :)
