2K Primer High Build

To apply the SPI 2K High Build Primer, use 7001-4 2K High Build Activator in a 4-to-1 mix ratio. Reduce with SPI 870, 885 or 895 up to 25%. Spray a wet coat using a 2-2.5 millimeter gun tip. You can use the SPI 2K High Build Primer with SPI Polar Accelerator during the winter or SPI Urethane Retarder during the summer. The pot life is 30-45 minutes at 75 degrees Fahrenheit. 

You can coat the surface with SPI 2K High Build Primer as many times as you feel necessary. Allow time to flash between each coat.

Flash for five minutes after the first coat before applying a second. The primer is ready to sand in 30-60 minutes for each subsequent coat, depending on the temperature. Apply about 2-2.5 millimeters per coat when using non-reduced primer. Reduce the final coat by 10-15% to minimize sanding requirements.

Yes. 2K High Build Primer is the first product to apply before a base coat or clear coat. Apply the next product after blocking the final layer of 2K High Build Primer. If more than 24 hours pass between sanding the final coat and applying the next product, scuff the 2K High Build Primer using a gray scuff pad.
