Everflow EF-290

High Solids Solvent Polyaspartic (2gal)

EF-290 is Everflow's high-build polyaspartic topcoat, the highest-solids clear coat in the line at 90 percent, so it lays down a thicker, more protective film over solid-color and vinyl flake floors in fewer coats. It stays crystal-clear and non-yellowing, cures fast enough to reopen the space the same day, and meets CFIA and USDA requirements for indirect food contact at under 50 g/L VOC.

Everflow EF-290

EF-290 is Everflow's fast-curing, high-build polyaspartic topcoat, the highest-solids clear coat in the line at 90 percent, so it lays down a thicker, more protective film over solid-color coatings and vinyl flake floors in fewer coats. Built for professional installers on limited-downtime jobs, it stays crystal-clear and non-yellowing while adding superior abrasion, chemical, and UV resistance over the color and flake beneath. It cures fast too: recoat in 2 to 4 hours, walk on it in 3 to 6, and reopen the space the same day.

Previously sold as MPC-290. Same high solids formula, renamed to Everflow.

What makes it work

Maximum-build clear coat in fewer passes

Grey epoxy flake garage floor sealed with a high-gloss polyaspartic clear topcoat
Highest-solids high-build
At 90% solids it lays down a thicker, more protective clear film in fewer coats than standard polyaspartics.
UV-stable clear finish
Aliphatic polyaspartic chemistry resists yellowing and chalking for a crystal-clear, high-gloss finish indoors and out.
Maximum abrasion and chemical resistance
Just 0.03 g of Taber abrasion loss shields the color and flake beneath from the heaviest traffic.
Same-day return to service
Recoat in 2 to 4 hours and walk on it in 3 to 6, so you can reopen the space the same day.
Flexible and tough
40% elongation at break resists cracking, with 5,150 psi tensile and about 0.75 DCOF wet traction.

What is EF-290 used for?

It's a high-build, UV-stable clear topcoat applied over solid-color coatings and vinyl flake (chip) systems. Its high solids content builds a thicker, tougher protective film in fewer coats, the premium clear finish of a floor system.

How is EF-290 different from EF-275, EF-280, and EF-285?

All are UV-stable. EF-290 has the highest solids (90%) for the thickest high-build clear finish. EF-280 is a 3-gallon thin-to-medium build, EF-275 a 2-gallon thin build, both clear polyaspartic topcoats. EF-285 is a clear polyurea primer that bonds to concrete.

Will EF-290 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?

At 68°F you can recoat in 2 to 4 hours, return foot traffic in 3 to 6 hours, and vehicle traffic in about a day, with full cure in roughly 7 days.

Can I apply EF-290 directly on concrete?

No, it's a topcoat, not recommended directly on bare concrete. Apply it over a prepared base coat or flake system, and ensure the slab has a moisture barrier to prevent 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 tint EF-290?

No. EF-290 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-290 as the clear topcoat.

Why does my polyaspartic floor show tire marks?

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 mats under parked vehicles where staining is a concern.

What is the working time after mixing?

About 15 to 20 minutes at 70°F. Mix only what you can spread within that window and never leave mixed product sitting in the bucket, where it sets rapidly.
