In the Inland Northwest, shifting seasons bring rain, snow, and big temperature swings that can wreak havoc on concrete. Many 1-day companies push polyurea or polyaspartic floor coatings as a fast fix—but is that really the best choice? Here are the answers to your biggest questions.
Does Moisture Really Matter in Inland NW?
Yes. Whether it’s spring thaw, wet fall weather, or heavy snowmelt, moisture vapor naturally migrates through porous concrete slabs in this region. Without a moisture-mitigating base coating (“primer”), that vapor becomes trapped under polyaspartic floor coatings, leading to bubbling, peeling, and delamination.
Should Polyaspartic Floor Coatings Be Applied Directly to Concrete?
No. While polyurea or polyaspartic floor coatings are great topcoats—fast-curing, tough, and UV-resistant—they cure too quickly to soak into the slab and form a strong bond (especially under moist conditions). Experts at Sika, General Polymers, and Dur-A-Flex recommend applying a 100%-solids, moisture-mitigating epoxy floor coating primer, first to mitigate for moisture, and second, to build a thick, solid foundation.
What Do Industry Standards Recommend?
Organizations like ASTM International, ACI, and ICRI require moisture testing, CSP surface prep, and vapor barrier primers before using low-permeability coatings like polyurea-polyaspartic floor coatings. ASTM F3010 even details protocols to prevent moisture-related failures that are common in areas with seasonal wet weather like Inland NW.
Are Lifetime Warranties from 1-Day Companies Reliable?
Most aren’t. They typically exclude moisture-related failures or set tight moisture thresholds that make claims nearly impossible. At Garage Floor Coating Inland NW, we follow a proven 2-day process: moisture testing, CSP surface prep, application of a moisture-mitigating epoxy primer coat, and then dual (not just one) premium polyaspartic floor coatings. Our warranty includes all moisture-related issues because we do the job right.
What’s the Best Way to Protect My Floor?
