Gorilla construction adhesive

[Eoughphily]

I'm replacing the stringers on my 17' riviera and am wondering if anybody has any thoughts on gorilla construction adhesive to set the stringers to the hull. If anybody has any experience with this can I also use it to make the fillets? I'm limited to home depot, Lowes, and Jerry's for my supplies on this project. Thanks

Also, on all my research I can find on this stuff, the only info I'm finding is with gorilla glue, not gorilla construction adhesive.

Gorilla construction adhesive, like Liquid Nails, in a regular or large caulking tube? Or their polyurethane based, amber glue in a squeeze bottle?

EDIT: I hadnt heard they introduced LiqNail type glue, but apparently they have

The first one, in a caulking tube

I don't know about any newer construction adhesives, but the older ones tend to gas out during the curing phase and end up with bubbles in the fillets. It's best to use what we commonly call peanut butter or as one member liked to call it, pooky, for fillets.

Search the forum for either "peanut butter" or "pooky" for the formula.

It also says its flexible so I'm wondering if its anything like 5200 for a fraction of the price. I've found some 5200 in a 10oz tube for $25 at jerrys compared to the gorilla on sale at HD for $5 (regularly $10)

When you use the term 'gas out' would that be like when it starts to foam? The GCA (gorilla construction adhesive) says non foaming formula.

Can you use marine 5200 for the fillets instead of 'peanut butter'?

3M 5200 is a runny-drippy mess and not nearly thick enough to set stringers with.

Lots of folks use the PL Premium in the caulk tube for stringer and transom work. You do have to wait 3 or 4 days for the adhesive to cure out before glassing over it, but most people do find that to be a problem.

get your 5200 on line. $25 is even higher than west marine. Lowes is about $23 for the 10 oz tube. should be $14 for a 10 oz tube.

I used PL. for the initial dabs, then I used PB for the fileting.

if you limit yourself to Home Depot and Lowes, you limit yourself to getting resin with wax in it. get your resin online as well (less than half the cost, and without wax)

 

[Eoughphily]

Is the wax bad or just gives it a different look?

 

[jbcurt00]

Unless you do all the fiberglassing in 1 layup, wet on wet, if the resin cures/drues, waxed resin needs to have the amone blush removed (dull haze on the surface) removed before the next layer of fiberglass and resin is applied.

Not a lot of resin sold at big box stores, so stock can be old. MEKP, the catalyst, has a short shelf life too. Can cause problems w expected cure times, or might not fully cure.

Regular Gorilla glue foams, I don't know about this stuff.

"Gas out" means during the cure process, a gas is produced which causes bubbles on the surface of the adhesive. This gassing is why you have to wait the 3 or 4 days like jigngrub said.

5200 is too expensive and too messy and the regular cure takes 7 days to cure, too long a time for stringer work.

Another consideration is the Resin sold at Lowe's and HD is more expensive than what you can buy online. Using any PL type adhesive can cause adhesion problems with the resin and glass when you start to tab the stringers to the hull. It doesn't like sticking to the rubbery compound. For these reasons most of our members buy their resin online and use the Thickened PB resin to bed their stringers. You could also just glue 1/2" foam to the bottom of the stringer and then use the thickened resin to form your fillets while using a stringer jig to hold the stringers in position during the cure.

 

[Eoughphily]

Where are you finding these cheaper prices online at? The resin I get at HD is $15 a quart or $35 a gallon. Any I find online is double that.

 

[JASinIL2006]

$30 a gallon (plus shipping) for standard marine layup polyester resin at U.S. C omposites. Can be used for layups as well as making peanut butter.

 

[Woodonglass]

You're gunna need a minimum of 5 gallons of resin, cabosil filler etc... and you're gunna need several yards of glass. You won't be able to buy that locally. U S C O M P O S I T E S . C O M has everything you need.

I did a test run today with the gca on some spare wood. Very strong stuff, cannot separate the wood. Ran a fillet down one side, perfectly smooth, no gassing. However if you make a mess of it you cannot sand it, so keeping it clean is must. I laid some test strips of fiberglass on it this evening. Tomorrow I will check it to see how well it sticks on the fillet.
