Nautolex and 3m spray adhesive?

Re: Nautolex and 3m spray adhesive?

Just for the record guys, the correct 3M spray adhesive to try would have been spray 80, not 77 or 90. Specifically designed for vinyl and rubber it has an adhesive that is compounded with a plasticizer inhibiter , plasticizer in the vinyl is usually what makes the adhesive bond fail. The plasticiser migrates into the adhesive and softens it. The yellowing of some white vinyls is often from the plasticizer being driven out by the use of an impropper adhesive. The plasticizer is not UV stable and so it yellows.

Re: Nautolex and 3m spray adhesive?

I had it one of my boats and for the most part it held up well. Over a fiberglassed deck I don't see any problems with it, over wood there may be some issues. It's a fairly tough product, but will get cut and nicked allowing water to get through. Over glass this isn't an issue, but if it's over wood then any water that get's past it will just stay in the wood keeping it wet speeding up the rot process.

I?d just go with a non skid paint or gel coat finish and then put in a snap in carpet over it if I wanted something soft for the bikini clad crowd.

.... As to the edges or seams the last 1/4" i used gorrilla glue in a clear form and rolled down the edges firmly...you have to stare very closely to see the seam and it will give you a headache if you stare to long...

Tail_Gunner, you have mentioned the use of gorilla glue in clear. I have only seen it in the maple syrup color that foams up. How does the clear work? Does it expand too, or is more like silicone?

Re: Nautolex and 3m spray adhesive?

Lots of posting going on here...For myself i used pl11 poly glue, not temp sensative...dries within hour....it takes only a very thin film which will make for easy removal someday. As to the edges or seams the last 1/4" i used gorrilla glue in a clear form and rolled down the edges firmly...you have to stare very closely to see the seam and it will give you a headache if you stare to long...

It's been in for a year now with no degradation...As simple as using a hose to clean and rinse....fish blood no problem....no fading yet i expect years of wear from this product...Remeber BoomYal that crabby old Phart.....He recomended it highly and he one old sour puss...i cant imagine if it satisfied him how anyone would be dissapointed....

May I repeat?

"Get a half gallon of the stuff upholstery shops use to anchor down vinyl roofs and other jobs. Spray it on with a siphon spray gun. It sprays very neatly and does not mist all over everything. You really hardly need to mask anything.

Multi-fold and position your flooring then spray glue on the floor and the vinyl and lay it down a section at a time. Start from the middle of the boat. Work forward, then turn around and work backward.

It is very neat with no mess and no excessive squishy glue. Guaranteed, it'll be down for the count. You can use the same stuff for your carpet.

3m spray adhesive is waaaaaaaaaay too expensive and there is no need for troweled glue or beads of glue."

You don't need no stinkin Gorilla glue!

Just make sure nothing important is behind what you are shooting at,,, in case you miss. It can easily go 6-7'...

Oh BTW, I still owe my wife a new cooler (not one that I have fouled up with fish goo)

Not so, fd. I was prepared for that but it did not occur. It went right where you sprayed it with no overspray. I had taped up newspaper everywhere and other than a couple of inches from your intended edge, it was totally un-necessary.

.....Oh BTW, I still owe my wife a new cooler (not one that I have fouled up with fish goo)

???? Have I forgotten something here?

Re: Nautolex and 3m spray adhesive?

Oh no, guess I didn't post clearly. You are 100% correct that it goes where you are shooting it with no overspray.

But, if you are shooting the contact cement at something and go off the edge, and there is nothing in back of the piece to catch the excess contact cement,,, it's going to go a long way.

IE: your shooting contact cement onto a part sitting on the work bench,,, and your wife's brand new cooler is behind the part, but 7' away...

You get to buy your wife a new cooler

Re: Nautolex and 3m spray adhesive?

Anchoring a vinyl roof and bonding a vinyl to a plywood deck are little bit different. On a deck you really want to fill the backing fiber with product not just stick it to the wood. I think a trowel application ensures that enough product is applied to achieve a saturated bond. 'Floating' vinyl can stretch, tear, or absorb alot of water if nicked.

I agree. The problem most folks have is in the application of the glue. They don't drag the trowels notched edge hard down on the substrate at a high enough angle and end up with way too much glue. You really don't need a ton of glue but in any traffic area you do need to cover the substrate.
In theory, the water resistant glue should provide some level of protection for the substrate if it is applied properly. With that said, we also must remember that water is natures solvent and in that way, it is very effective.

Agree, if Marine Vinyl was like kitchen viny or rubber backed carpet then 80 would be the correct choice. The Marine Vinyl I have has a woven fiber backing.

I've got some 3M Fastbond "Blue Glue" 4224-NF that I'm going to try on a sample. I've used it with latex backed carpet on concrete floors and it holds extremely well. Maybe too well.

3M has a citrus based solvent that only softens it so you can get a long handled scrapper under it. Its a bear to remove.

FYI - Here's a link to what WM carries- It is completely waterproof when dry.. http://www.westmarine.com/webapp/wc...=true&storeNum=18&subdeptNum=622&classNum=623

Re: Nautolex and 3m spray adhesive?

BTW, a quick note on comparison shopping for Nautolex vinyls: Nautolex is priced by the linear yard, not the square yard. Nautolex deck vinyl is available in two widths: 54" and 72". So when comparing prices, be sure you are also comparing widths.

West marine sells the 54" deck vinyl for $28.99 a linear yard.

Defender sells the 72" deck vinyl for $17.95 a linear yard.

So not only is W.M. price $11.04 more a linear yard, you get about 33% less product than if you bought from Defender.

Re: Nautolex and 3m spray adhesive?

Cabela's is in the middle. I bought 21' of the 72" for around 170.00

Re: Nautolex and 3m spray adhesive?

I've seen places sell it by the square yard, or by running foot,,, instead of running yard. So where ever you get it, make sure you know how they measure it out. BPS is one that sells by the foot.

Re: Nautolex and 3m spray adhesive?

defender*dot*com is the place to buy it for sure. I just bought 12 yds of the shark grey for $16.95/ running yard. It was on sale for their annual clearance sale. It's still sitting in the garage. I spent the day building out the deck structure in my '74 18" Starcraft Chieftain. I'll have 4 batteries and fuel tank under the deck this time! I bought the Nautolex 88 adhesive and will lay it down the way it's intended. The spray on stuff may be easier to apply, but what's the point if it won't hold over time? I used 3M on carpeting in the past and once wet, it didn't hold long.

Agree, I used it only when I could back it up with staples or if it was in an application where there was a clamping effect around the edges. The spray is great for holding your foam in place when you do your upholstery. That's a little trick I learned along the way. It'll make your upholstery job look professional and tight like it should.

Re: Nautolex and 3m spray adhesive?

Not sure how this thread got resurrected, but here's my 2 cents on the Nautolex: My new restore project has a vinyl deck, and it still looks ok after 50 years. But other than a restore I won't use it unless I can hold down the edges mechanically, like carpet edging.

Even sheet goods adhesive won't hold without edging, and the boat I tried to use this stuff in looks like crap a year later without it.. you have to be able to use edging where you need it.

Re: Nautolex and 3m spray adhesive?

Thanks for mentioning clamping sschefer! That turned the light on for me when it comes to what to about rolling the Nautolex into hatch frames and around covers. I'm not too keen on using staples unless I can find some ss or aluminum ones. I'm also going to try to end up with somewhat waterproof hatches... haha!! We'll see!!

Thanks again!

Re: Nautolex and 3m spray adhesive?

Erik,

I think I'll try and use 1/2" 1/4 round trim (the kind used in kitchens and baths) it's closed-cell foam so it's waterproof and painted grey will look nice. One thing I am doing is covering the full deck first, then building in a few storage cabinets under the splashwell, so there won't be any seams in the Nautolex at all.....hopefully!!
