Polyaspartic Floor Coating Myths: The Facts You Need

Across Akron and Cleveland, 1-day companies promote polyurea or polyaspartic floor coatings as the ultimate quick solution for garage floors. But experts say many of these claims are misleading—and skipping critical steps puts your investment at risk. Let’s bust the myths and share the facts on building a floor that lasts in Ohio’s challenging climate.

Myth: Polyaspartic Floor Coatings Don’t Need Epoxy Primers

Many fast-install companies claim quick-curing polyurea and polyaspartic floor coatings bond perfectly to concrete without a primer.

Fact: Top manufacturers like Sika, Dur-A-Flex, and General Polymers warn that polyurea-polyaspartic floor coatings cure far too quickly to penetrate into concrete pores. Industry standards recommend applying a thick, slow-curing, moisture-mitigating 100%-solids epoxy floor primer first. This primer is a moisture vapor barrier, ensuring moisture mitigation and a strong mechanical bond that lasts.

Myth: Ohio Garages Don’t Need Moisture-Mitigation

Some installers suggest Ohio’s cold winters and mild summers mean you don’t need to worry about trapped moisture.

Fact: Even in cold months, moisture vapor can migrate up through the slab—especially in Northeast Ohio, where snowmelt and heavy spring rains saturate the ground. Without a moisture-mitigating primer coat, that vapor builds hydrostatic pressure beneath the surface, leading to blistering, peeling, and delamination. ASTM F3010 requires moisture vapor barriers under resinous coatings precisely to prevent these failures.
