Is urethane primer the same as epoxy primer?
Since urethane is only a primer surfacer, you’ll also need to apply a sealer before you paint. Again, a coat of epoxy primer over the top will serve the purpose. Some restorers believe filler primer is little more than liquid body filler. In most cases, the filler primer or high-build primer is also a urethane product.
Do you add hardener to primer?
Mix the primer according to the manufacturer’s instructions! There are lacquer primers that you “thin” out to spray, and there are 2K (two component) primers that require a hardener to be added.
How do you mix urethane primer?
2K URETHANE PRIMER must be prepared by mixing 3 parts of part A- KUP- 405 base with 1 part of part B -KUP-406 Hardener (by volume). Any mixture of 2K URETHANE PRIMER A & B will have the hazards of both components.
How many coats of epoxy primer do I need?
The epoxy primer should be applied in medium wet coats, allowing a half an hour between each coat at around 70 degrees. One to two coats will render a one millimeter dry film thickness, which is typically enough to be completely effective. Make sure to evenly spray each coat completely across the bare metal surface.
Can you spray epoxy primer over rust?
They in no uncertain terms told me that you definitely should not cover any rust with epoxy primers. Furthermore, you should not cover their rust converter with an epoxy primer. I asked if that meant that I needed to sand off all the converter.
Can you paint right over epoxy primer?
Epoxy primers have excellent adhesion properties and will stick to bare metal, paints, primers and fillers. Alternatively, you can apply filler or primer surfacer over the epoxy to fill any minor imperfections and block flat before you paint.
What are the correct mixing of primer and thinner?
For spray applications on construction or home projects, begin by reducing the primer by 10 percent. This would call for adding approximately 3 oz. of paint thinner to each quart of primer (32 oz. x 0.10 = 3.2 oz.), or roughly 13 oz.
What is an epoxy primer?
Epoxy primer is a sealer that produces a good surface finish on applied top coats. A two-part epoxy primer contains zinc phosphate, which acts as a corrosion-inhibiting pigment. Epoxy primers are also used in structural steel coatings for high-build thickness with the application of only one or two coats.
Does epoxy primer need reducer?
To prepare the epoxy primer, shake or stir the primer, and thoroughly mix one part primer with one part catalyst. To reduce any film buildup, this one to one ratio can also be cut with a urethane-grade reducer or comparable solvent solution. This can also improve the overall flow of the primer mix.
