When it comes to garage floor coatings there are tons of resinous products to choose from. Commonly they are all known as epoxy but chemically speaking they are very different.
Polyurea was introduced in the last decade and quickly became the industry standard over traditional epoxy coatings. What is a polyurea coating? It’s a kind of polyurethane resin that seals concrete and offers excellent resistance to stains, chemical spills and abrasion.
Like most things in life, it comes down to the cost. Polyurea is a high solid 2-part resin that can be rolled on a treated floor these factors add to the cost. Another reason you don’t see it in the home kit is due to its short pot life (~20 minutes). Applying the coating uniformly and quickly is better suited for experienced installers. Improper mixing of A/B resins combined with the working time makes weekend warriors shy away from polyurea coatings.
Recently polyurea single-part products have been released on the market. They work by relying on the moisture in the air to initiate the chemical reaction. The high cost of this product hasn’t yet cracked the DIY shelf at major retailers.
DIY epoxy kits are a low-cost temporary solution for refinishing garage floors. For results that last you need to prepare the surface, repair cracks, prime the floor, and apply multiple coats of coatings. To do the job properly, you need diamond floor polishers, industrial shop-vac and experience.
Switching from epoxy to polyurea was a great move for the coating industry. These days delamination around the garage entrance is a rare occurrence which means fewer repairs for us and happier customers. We developed an installation technique that constrains delamination to the front edge of the garage in the event your floor experiences poor adhesion (but since changing from epoxy we rarely experience issues).
