Hi couple of questions from the uk

[Restoration man]

I’ve got 1976 Storebro biscay, Swedish boat, ive got windows out to change the seals etc and there is a wooded support glassed In very badly, it was bit rotten and was actually bonded to pice of 4/5 mm aluminium strip that is in turn bonded to fiberglass first , this is original it’s not been bodged up , the front deck was aways a bit springy I assume this was done to strengthen the deck at the factory there is also a hatch above ,I don’t see the point of the aluminium it wasn’t properly bonded to the inside of the superstructure it was loose and the wood wasn’t bonded to the aluminium very well either , would I be better omitting the aluminium strip and just increase the thickness of the wood? going to set the wood into west epoxy thickened with 406 then 2 layers of combi mat

welcome aboard

aluminum is normally bonded in as a screwing strip for things like windows, cleats, etc.

That’s what I initially thought ,and that’s exactly where the hinges for the hatch are screwed from above but the fiberglass is so thick the screws don’t penetrate the aluminium,so it’s not really doing anything and the screws in the hinges are holding fine , I don’t think the ally is adding any Strength to the deck infact I think it’s actually loosing strength as it wasn’t bonded in correctly, hence why I’m Considering not putting it back , I’ve got a nice piece of mahogany that’s about the right size, would that be ok to use and bond in with epoxy thickened with west 406 Colloidal silica and glassed over with 1708 ? I assume you have to prime the wood first with un thickened epoxy first and let it kick before adding the thickened epoxy and clamping it into place and then glassing over when it’s kicked ? I’m assuming I don’t want to wait for it to fully harden as I would then need to sand the amine blush off? I’ve been reading on her for a while and watching you tube videos , so hopefully I’ve got the right idea ?sorry for all the questions I’m new at this fiberglass stuff

you cant use epoxy with 1708. you need the styrene in the poly to dissolve the binders in the CSM stitched to the 1700 cloth.

I would have just used poly.

regarding the aluminum screw strips. the screws should have gone to the aluminum. however most boats suffer from very shoddy workmanship from the factory. (remember, boats are slapped together with the minimum amount of effort to get the maximum profit and only designed to last 15 years)

suggest reading links 14, 15, 18, 2, 3, 4a, and 4b

Hi I think the combi mat supplied in the uk is compatible with epoxy , also how do I get to the links you have supplied

If you use epoxy don't sand the blush .. Scrub it with warm water and a dab of soap .. Sanding will just grind it further into the glass ..

Hi ,after I’ve washed the blush off I assume I will still need to sand it to create key for the next coat of epoxy and mat ?
