Epoxy Coatings vs. Polyaspartic Coatings

Updated: Jul 30, 2020

Ever since the construction of the first concrete floor, humanity has searched for a way to protect and beautify the surface. Epoxy coatings have been around for some time and have been popular protectors of concrete floors. Fairly new to the party, polyurea polyaspartic coatings have quickly become the darlings of those who want a fast dry time. Let’s examine each of these contenders and see how they stack up against each other.

Advantages of Epoxy Coatings:

Not expensive

Creates a hard, beautiful finish

You have many finish options, including colour and mix-ins

Highly durable

Resistant to chemicals

Good adhesion — won’t lift

Long pot life, allowing application with a manual gun

Disadvantages of Epoxy Coatings:

Less flexible and less resistant to abrasion

Can be somewhat difficult to apply in hot or cold conditions

Has a long drying time

Has potentially hazardous vapors, although new formulations address this

May not be colorfast — subject to fading or yellowing from UV exposure, though many formulations include UV protection

Cannot be applied when temperature below freezing

Advantages of Polyaspartic Coatings:

Easier application in a wide variety of weather and temperature conditions

Hard, smooth finish that is stain- and scratch-resistant, good for high-traffic areas

Clear and non-sticky when dry

Fast drying times, cures to full strength in 1/2 to 1 hour

Colours and decorative chips available

Colour-fast, even when applied to slightly damp concrete

Low VOC's and odour

Low viscosity gives it good wetting ability on concrete, but requires reduced percentage of solids

High, controllable film build-up

Less likely to bubble from out-gassing

Disadvantages of Polyaspartic Coatings:

Relatively new product, professional application recommended

Short pot life

Two to three times more expensive to purchase and apply

Must avoid high moisture vapour emission rate conditions when applying

Might have to thin the first coat for better adhesion

Doesn’t stand up as well to battery acids

Very slippery when wet, so a top aggregate such as chips recommended
