Primer NOT adhering to gluvit after sanding/wire wheel

[PaulyV]

OK..I resanded AND wire wheeled the areas that spidercracked. I wire wheeled almost down to the bare aluminum, pretty much removing most of the Gluvit I applied....and still after 30-40 mins..it seperated. The aluminum primer is Latex based. is this the issue? Will oil based paint adhere better?

It depends on the actual primer you are using, but in my experience with water and oil based products, the oils are more forgiving. What is the base of Gluvit? I've never used it or seen it, so I can't say. However, if it contains stearates or something that the water based primer doesn't like, then you are going to have all sorts of troubles. The fact that you had spider webbing in the first place means you had incompatibility problems.

Thanks for the response RedFury

This off the website:

For maximum ultraviolet protection, Gluvit must be painted after cure. Before over coating, lightly sand this waterproof epoxy sealer to ensure adhesion. Any pigmented epoxy, urethane, latex or alkyd base paint can be used to overcoat Gluvit.

Thats what has me confused. Waterproof epoxy..that says latex (water based) can be used after light sanding.

"For maximum ultraviolet protection, Gluvit must be painted after full cure. Gluvit can be overcoated with any marine paint or other coating compatible with epoxies. Check with your paint supplier and make sure the coating you are using is epoxy friendly and suitable for your application."

and

To overcoat Gluvit after cure, wash the surface with warm soapy water or a dilute vinegar solution and a fine abrasive pad, or wet sand, then dry with clean towels or cloth. Frost-sand surface with 80-100 grit sand paper to remove any gloss. Gluvit can be overcoated with any marine paint or other coating compatible with epoxies.

This is what I just did a C&P on from the website.

well...did all that but wiped down with acetone..so I guess thats the issue. or its not cured totally..its been 72-76hours.

Get rid of the wire wheel, its of no value in this application. Gluvit needs to fully cure before you paint over it, heat will help drive the cure. If the surface feels soft or gummy at all, its not ready for painting.

I most likely jumped the gun here. Thanks

unless you're in a 70 degree shop you're days away from full cure.
Not sure that's the problem, but at 60-65 mine was three - four days before it felt solid as glass, and that doesn't mean there still wasn't a chemical reaction going on.

Nah..its all good now...I just rushed it..I am like a kid at Christmas over here!

I built a (plastic) room on my side of the garage, which should have been done when I started..but..I get over anxious.

The gluvit sanded down nicely the following evening.

I will post pics of my setup on my restore page later. I have the boat painted as well...!!!
