SAME GARAGE. DIFFERENT CHEMISTRY.

The short version

Epoxy is a two-part resin system that has been used on concrete floors for decades. It builds thickness well and bonds strongly to properly prepared concrete. Many standard epoxies can yellow (amber) with sunlight exposure, which is one reason they are often finished with a different topcoat.

Polyaspartic is a type of aliphatic polyurea coating. It typically cures much faster than epoxy, is generally more resistant to UV yellowing, and is used as a topcoat or as a full system. Some polyaspartic data sheets also allow application at lower temperatures than typical epoxies, which matters in cold GTA garages. The fast cure shortens the working time, so installation technique matters.

Many systems combine them

A common garage system is an epoxy base coat, often with flake, under a polyaspartic or polyurethane topcoat. So the useful question is not just epoxy or polyaspartic, but what each layer is, how thick it is, and why it was chosen.

How to make two quotes comparable

• What product is used for each layer: primer, base, broadcast, topcoat?
• How thick is each layer, and how many coats?
• How is the concrete prepared, and to what surface profile?
• Is there moisture testing, and what happens if the slab fails it?
• How are cracks, joints and the garage door edge handled?
• What does the written warranty cover, for how long, and what voids it?
• When can you walk on it, and when can you drive on it?

Where Epoxy Mind fits

Epoxy Mind's published finishes are metallic, flake, solid-colour and marble-art epoxy. If you're comparing our quote with a polyaspartic quote, send us the other system's layer list and we'll explain the differences in plain terms.
