Frequently Asked Questions

1. Which is stronger, epoxy or polyurethane?

Epoxy is stronger and more rigid, making it excellent for durability and heavy loads. Polyurethane is more flexible, which helps it resist cracking from temperature changes or impacts.

2. Do you apply epoxy or polyurethane first?

Always apply the epoxy first. You must wait for the epoxy to fully cure before adding a polyurethane topcoat. This can take anywhere from a week to a few weeks, depending on the specific product and conditions.

3. What is a polyurethane topcoat?

A polyurethane topcoat is a durable protective layer applied over a finished surface. It creates a hard, plastic-like barrier that is highly resistant to scratches, stains, chemicals, and weathering, making it more protective than a standard clear coat.

4. How long does polyurethane take to dry?

Polyurethane is typically dry to the touch in about 3 hours. For a second coat, you should wait at least 6 hours, although letting it dry overnight is recommended for the best results.

5. How many coats of polyurethane should I use?

For most indoor projects, you should use two to three coats of polyurethane for optimal protection and durability.
