Question about gluing in vinyl d-ring patches

boatbuster · Post by **boatbuster** » Mon Jan 07, 2008 8:55 pm

I am outfitting a new boat and it has been a long time since I glued in any D-ring patches with vina-bond. These are for the airbag anchors. Do I put the vina-bond on both sides and let it get tacky like a contact cement before putting the d-ring down?

Thanks

You need to let it dry completely, then hit it with a hair dryer. Leaving it tacky will result at best in a poor bond and at worst with a soft/delaminated hull underneath the patch.

I'm leaning toward using epoxy these days - I have trouble finding the original Vina Bond brand stuff, and the generic 'vinyl adhesive' white tubes that most paddling shops carry seem to really suck.

You can get vynabond from NRS. The link is http://www.nrsweb.com/shop/product.asp? ... eptid=1032 .

I am going to reiterate the LET DRY COMPLETELY from the post above. Do apply the vynabond to both surfaces and LET DRY COMPLETELY. Never mind the poor bond, the hole in your boat is much worse. Also make sure to rough up the surfaces with sand paper then clean well with Denatured Alcohol, or a mild solvent, try not to use Aceton, too abrasive. Let the solvent dry completey before applying the vynabond. After the vynabond has dried, as mentioned above, hit with hair drier or low heated heat gun to 'retac' the vynabond. After I put the patch into the boat i like to while it is drying use a bag of frozen peas or ice and rub it around the patch and hull to keep the heat down as vyanbond creates hot reaction. This step isn't necessary but may provide peace of mind. Good Luck

Here's what we do and its been very successful. Clean both surfaces with alcohol and sand with 320 grit , then reclean. Coat both surfaces with a light coat of vinylbond and let dry. Re-coat both surfaces and put together immediately while wet , and use a squeege to remove air bubbles . Let dry 48 hrs @ 65 deg or better. Be careful not to use too much vinylbond at one time. light coats are best. It will not come off.

I couldn’t get vinabond here in mexico so I used oatey pvc cement with really good result and no boat damage.
