Primer 1 - Acid

This is used for problematic clients as an extra insurance of adhesion to acrylic or hard gel. You wouldn’t use this primer alone. It would be applied prior to primer 2 for these clients or new clients if you need to know lifting wouldn’t be a problem.
Primer acid has a high freeze temperature so please note that if left overnight in working environment without heating in winter you may need to be careful unscrewing the bottle lid. Put product in a warmer area for a little while to avoid frozen liquid pulling the bristles from the brush.
