Primers for Concrete Floors
These thin primers penetrate deeply into concrete floors to create a hard surface that can then be coated with any urethane or epoxy coating. Primers resist abrasion and chemicals, such as mild acids, alkalies, salt, and fuel. Apply with a roller. The size listed is the combined total of the two parts.

Thin Film and Label Application Primers
Spray these primers onto a mounting surface to quickly and smoothly apply signs, labels, and protective films. These primers float adhesive-backed sheets above a surface until you press them down, giving you time to position the sheet and remove any wrinkles. Since the sheet doesn’t stick right away, you can apply large sheets without needing a second pair of hands. These primers also work with non-adhesive films. Even in hot or cold temperatures, your sheet will stay put.
Clean the mounting surface with primer before applying a film, so no residue is trapped underneath. Use a smoothing tool (sold separately) to squeeze out air bubbles and excess fluid. Drying time depends on application—most decals and films will dry within 90 seconds, but 3D printer sheets should dry for 24 hours before printing.
