Easy-Sand, Best Choice Primer for Plugs and Molds

Duratec® Gray Surfacing Primer is the best choice for coating your plug or reconditioning your mold. It is suitable for use with wood, MDF, tooling board, composite plugs, patterns, and models. It offers excellent adhesion to most epoxies with a heat distortion level of 200° F.

The unique air-cure technology allows fast cure even with thin coats. It can be applied as heavily as 45 mils to fill fabric pores on plugs or over repairs. To reach your desired spray viscosity, you can thin 5%-15% with #2306 Duratec® Thinner.

Duratec® Surfacing Primer offers minimal shrinkage and a porosity-free surface without pinholes or defects. It features a super-fine levelling and filling system that sands easily, builds rapidly up to 40 mils on composite plugs, and can be polished to a Class 'A' mirror finish.

Requires 2% MEKP.

Nice primer for plugs and molds

Nov 6, 2022  |  By Michael

This primer really sands well for a great finish. It sprayed a bit differently than other polyester primers that I have used in the past and required a little bit of thinning with Duratec Reducer, but it went on fine and it sands very well. My plug finish is now really excellent.

This is the very best primer/surfacer product I have ever used. Great service, sadly I ordered just prior to a public holiday which, delayed delivery but once the holiday was over everything was simply perfect. This primer can be polished to a glass finish with ease and was a perfect choice for pre-tooling gelcoat coverage. BRILLIANT!

Duratec- Excellent, but too much

Very good product. Goes on thick and flows into surface flaws nicely. However, for smaller projects, gallon-only size is way too much. I had a nearly full gallon from a few years ago and it went bad. I will have the same problem with this gallon.

I really like the product except that the shelf life is very short. It would be nice if you sold this in quart cans.
Owner Response: Thanks for your honest feedback, Joel. I will take this to the product team immediately!
