What is epoxy primer used for?

An epoxy primer is very effective at sealing up bare metal and prevents moisture or corrosion from creeping in. It keeps out oxygen, ensuring that rust or corrosion do not form on the surface. It is non-porous when it cures and does not soak up moisture like most primer sealers.

Is epoxy primer necessary?

There are numerous benefits in applying an epoxy floor primer prior to coating your flooring: Epoxy primers are thin, providing a better adhesion as it penetrated into the concrete substrate allowing a better bond. Primers provide a better chemical bond when using thicker epoxy base coats.

What’s the difference between primer and epoxy primer?

Self etching primer bonds well to bare metal surfaces and can be top coated in a short period of time. Epoxy primer can be applied in heavy coats which can be guide coated and block sanded to remove small imperfections in the body. Epoxy primer takes longer to dry (cure) before it can be sanded or top coated.
