Polyaspartic vs Epoxy

Polyaspartic is superior to epoxy in strength, adhesion, flexibility (epoxy cracks), UV stability (non-yellowing), speed (dry time is 2 hours vs 24) and resilience (it wears down 3x slower). As you can see in the product data sheet above polyaspartic has over 6,000 pounds of strength vs epoxy's 3,000. The adhesion strength is also 125 pounds greater.

What is Polyaspartic made of? It is a type of polyurea that has undergone changes to make it UV stable and stronger. Polyaspartic is a is type of polyurea, but not all polyureas are polyaspartics. Polyaspartics are far superior than regular polyureas. Just like Corvette is a type of Chevrolet, Polyasprtic is a type of Polyurea. Polyurea that is not a polyaspartic is cheap, weak, and will yellow unlike polyaspartic. So make sure you don't get confused by the two. Many people sell polyurea because it is cheap. If you want to remember which one is better just think of Spartica like in the movie Gladiator. Poly-a-spartic.

Polyasartic has 'give' 'resilience' or 'flexibility' so that when impacts hit it, it 'gives' and then returns to its normal position opposed to epoxy which can not flex and therefore cracks under pressure. Resilience is the ability of a substance or object to spring back into shape. Epoxy has no resilience, it is brittle and it cracks under pressure. This is why polyaspartic wears 3X longer. It is also resistant to staining unlike epoxy becuase it is relatively non-porous. Epoxy is very porous and stains easily. Polyaspartic also dries much faster than epoxy; in only 2 hours it is ready for foot traffic and in 12 hours it is ready to drive and park you car on it! That means you won't have all your stuff sitting outside for 5 days like with epoxy floors. Polyaspartic is Better, Faster & Stronger!

Epoxy Coatings

One of the many downsides to epoxy is that it is brittle which means it will not flex when the concrete cracks move. All concrete cracks move when the temperature changes and if the bridge over the crack is not flexible it will buckle and peel as seen in this video.

So, the question of polyaspartic vs epoxy is pretty clear.
