Everflow EF-275 | Solvent Based Polyaspartic (2gal)
EF-275 is Everflow's solvent-based aliphatic polyaspartic topcoat, a crystal-clear, UV-stable clear coat that seals solid-color coatings and vinyl flake floors and lets you reopen the space the same day. Built for professional installers on limited-downtime jobs, it resists yellowing and chalking while adding superior abrasion, chemical, and UV protection over the color and flake beneath.
Same-day clear coat for flake and color floors

Frequently Asked Questions
What is EF-275 used for?
It's a UV-stable clear topcoat applied over solid-color coatings and vinyl flake (chip) systems to seal in the finish and protect it from wear, chemicals, and sunlight. It's the final clear layer of a floor system, not a base coat.
Will EF-275 turn yellow?
No. As a true aliphatic polyaspartic, it resists yellowing and chalking and keeps a crystal-clear, high-gloss finish in both interior and sun-exposed applications.
How quickly can I reopen the floor?
Fast, at 68°F you can recoat in 2 to 4 hours, return foot traffic in 4 to 8 hours, and vehicle traffic in about a day. Full cure is roughly 7 days.
Can I apply EF-275 directly on concrete?
No, it's a topcoat, not recommended for use directly on bare concrete. Apply it over a prepared base coat or flake system. Make sure the slab has a moisture barrier to avoid delamination.
How much does one kit cover?
A 2-gallon kit covers about 400 sq ft at 8 mils over an existing coating, or about 267 sq ft at 12 mils over a vinyl flake broadcast system.
Can I get EF-275 in a color?
No. EF-275 ships crystal clear only, and Latux does not offer a color pack for it. Build the color into the layer underneath with a solid-color base coat or a vinyl flake broadcast, then seal it with EF-275 as the clear topcoat.
Why are there tire marks on my polyaspartic floor?
Rubber tires can stain a polyaspartic coating through plasticizer migration, and quick stops or starts can leave rubber burn marks. This is normal for clear coatings; use floor mats under vehicles where staining is a concern.
What is the working time after mixing?
About 20 to 25 minutes at 70°F. Mix only what you can spread within that window and never leave mixed product in the bucket.
