What's a Good PVC Glue?

[Divemaster5734]

Been looking around for some PVC glue.
Being a total newb, I'd rather not find out some random brand I picked is total garbage as I'm watching an oar float away with the pad still attached.
Have rope pads, oar locks, and partial SIB detachment to repair.
Hoping for experienced brand recommendations.
Thanks

I have been using Stabond with great success, and it can bond PVC to PVC or Hypalon to PVC. NRS carries it along with any material you should need.

Prep is everything. Can you get MEK still in WA? We can't get it in CA anymore as it is a horrible chem, but works awesome! MEK is the pre-wipe prep prior to gluing for PVC. Clean with Acetone, scratch the surface with something like 60 grit, clean again, wipe with MEK, apply first layer of glue, let it dry, apply second and when tacky stick the parts back on. Make sure to press them on with either a roller or a well rounded blade.

What kind of boat? Year? PVC has a limited lifespan and sometimes everything needs to be reglued if there is sun damage. Point being if one part of the floor is falling off it all needs to be removed and reglued. Most likely including the transom.

Ordered both from NRS a few minutes ago.

The boat was a neighbor's who never used it, and gave it to me when he moved.
The plaque inside the transom has a serial number, but no manufacture date.
It's a Bestway Hydro-force, rated for up to 15 HP and 5 persons.
I went to their website and entering that serial came up with no results.
I remember about 4 or 5 years ago he dragged it down to the water inflated, flipped it upside down, and it never moved again until he dragged it over to my shore.
It's still holding air from the original fill, but I never inspected it when I told him it was OK to leave it.
One of the grab rope pads is fully separated, one of the oarlocks is partially lifted, and a narrow part of the SIB, at the rear, is lifted.
I was just planning to use it to get to a large mouth bass shallows cove of the lake that's about 100' from my shore.

What's the best way to remove the remaining portion of something that still has a good adhesion?

Also, is there anywhere to read up on how to do the weave to replace those grab ropes?

Thanks

I would recommend peeling more and see how far it goes. What brand and make of boat is this? Year? Got any pictures?

Heat gun is the best tool. You will need to apply a lot of heat, but not melt the plastic. Keep the gun moving constantly. This gun works well and is adjustable.

Removing the glue is another issue. Acetone and a thick weave scuffy pad works well without removing much of the material. Some folks use a random orbital but it is too easy to remove too much material even with 120grit.

Safety items needed will be neoprene gloves and a good respirator. I can't open Home Depots website in France but you are looking for a longer pair of gloves that are black to be found in the paint section. 3M has a good cartridge respirator HD sells for around $40, also in paint. Grab a gallon or two of Acetone and Scuffy pad, also in paint. Sandpaper if you don't stock any.

Something like this respirator.

A roller or some kind of metal for pushing the glued material down is needed. I'd prefer it be around 1.5". Personally I am not a fan of rollers and instead made my own tool. I took a tool like this and cut it off at the bend, then rounded the edges over, especially the corners forming a 1/4" round corner. I do a lot of metal working though and have the tools to do so, and don't know your tool situation.

Meh a roller.

I didn't watch it but this is the general idea. You can search for "splicing anchor rope". I like 1/2" 3 strand rope for grab handles.
