No Prep Primer eliminates the need to prep by etching or grinding, saving significant time and money. Ideal for where dust created by grinding or shot blasting is an issue or when downtime is critical. Allows you to easily prime and epoxy in one day! Once applied with a garden-type sprayer, simply wait 10-15 minutes for the No Prep to get ‘tacky’ and then apply your coating. Virtually any coating (except water-based epoxies) can be applied to ArmorGarage No-Prep Instant Primer. Can be used as a standalone primer on bare concrete, or as a primer to assure adhesion to an existing coating that is being recoated.
ArmorGarage No-Prep is so strong that adhesion tests have proven that the concrete surface will fail before the primer will delaminate! Simple one-part no mixing formula.
Sold in 1 Gal units. Coverage is 300-400 sf/gal.
This primer must be applied with an acetone proof pump sprayer, ex. Swissmex, with a cone tip. Keep spray tip 18 inches off the ground and apply product slowly in a circular motion, similar to how a stain is applied to concrete.
Allow primer to tack up for 15 minutes and apply epoxy coating using spiked soles. Primer must be topcoated with the epoxy within 90 minutes. Prime floor is sections so as not to have to rush epoxy application. Be sure to leave wet edge of primer to overlap next section. If you miss the 90 minute window simply sand primer with 100 grit and reapply primer.
