Polyaspartic High Solids Topcoat Coating System - 2 Gallon Kit Gloss

In this review the Polyaspartic High Solids Topcoat Coating System is presented as a practical, professional-grade clear topcoat for garage floors, countertops, and industrial floors; the bottom line is that contractors and confident DIYers will appreciate its high-solids gloss finish and solid chemical and UV resistance. The two-component 1:1 mix and the availability of medium cure speed make it straightforward to apply for typical conditions while still offering faster or slower cure options for specific jobsite needs.

Key Features

• High-solids formulation: Delivers a durable, glossy clear coat that helps resist abrasion and scratching on both residential and industrial floors.
• Aliphatic polyaspartic chemistry: Provides strong UV stability so the finish dries to a non-yellowing, crystal-clear appearance outdoors or in sunlit interiors.
• Versatile cure speeds: Available in Fast, Medium, Slow and XTRA Slow options so installers can choose a working time that fits temperature and humidity conditions.
• Simple 1:1 mix ratio: Mixing base and activator by volume with a low speed drill and Jiffy blade makes batch preparation consistent and repeatable.
• Thick single-pass sealing: Can be applied up to 16 mils wet in one pass, enabling efficient sealing of floors broadcast with decorative chip or quartz.

Who It's For

This coating is aimed at contractors, professional installers, and experienced DIYers who need a tough clear topcoat that resists chemicals, UV and abrasion for garage floors, industrial bays, or countertops. The product works well over broadcast chip systems and decorative quartz where a glossy, non-yellowing finish is required.

Less experienced users or very small single-person jobs may prefer the Slow or XTRA Slow versions for extra working time; conversely, hobbyists expecting very long open time in extreme heat should consider planning work in cooler conditions or choosing the slower cure option to avoid premature set-up.

Pros & Cons

Pros

• High-solids formula produces a hard, glossy, non-yellowing finish that stands up to chemicals and abrasion.
• Multiple cure speeds let installers match working time to temperature and humidity for predictable results.
• 1:1 mix and standard application methods make it practical to use without specialized metering equipment.
• Applies up to 16 mils in one pass, reducing return-to-service time on broadcast systems.

Cons

• Working time is affected by heat and humidity, so haste or cooler slower cure options are required in extreme conditions.
• Proper technique (squeegee, back-roll, non-shedding roller) and mixing discipline are needed to avoid visible tie-ins between mixes.

Our Verdict

The Polyaspartic High Solids Topcoat is a practical and cost-effective clear finish for installers who need fast return-to-service and strong resistance to UV and chemicals. Professionals and competent DIYers will find the 1:1 mix, multiple cure speeds and ability to seal broadcast systems in one pass make it good value for garage and light industrial projects where a glossy, durable finish matters.

Frequently Asked Questions

How is the product mixed?
Mix base and activator 1:1 by volume and stir with a low speed drill and Jiffy blade for three minutes until uniform.

What spread rate should be used?
Apply at 100-160 sq. ft. per gal to yield roughly 10-16 wet mils; heavier wet mils can be achieved in a single pass up to 16 mils.

How does heat and humidity affect application?
Higher heat and humidity shorten working time; use the Slow or XTRA Slow cure options or switch to dip-and-roll with an 18 roller to maintain uniform coverage.
