Everflow EF-285
VOC Compliant Solvent Polyurea
EF-285 is Everflow's solvent-based aliphatic polyurea coating, a UV-stable primer and base coat in one that bonds to diamond-ground concrete and resists yellowing and chalking. Latux stocks it in clear at 85 percent solids, and it primes and protects in a single fast-curing coat while meeting CFIA and USDA requirements for indirect food contact at under 50 g/L VOC.

Everflow EF-285
EF-285 is Everflow's solvent-based aliphatic polyurea coating, a UV-stable primer and base coat in one that bonds directly to diamond-ground concrete and resists yellowing and chalking. Latux stocks it in clear, and it primes and protects in a single fast-curing coat for professional installers on limited-downtime jobs.
Sold for years as MPC-285. Same polyurea, new name on the pail.

What makes it work
UV-stable primer and base coat built for prepared concrete
UV-stable polyurea
Aliphatic polyurea resists yellowing and chalking while adding superior abrasion, chemical, and UV resistance.
Clear UV-stable primer and base coat
Latux stocks EF-285 in clear. It works as a UV-stable primer and base coat on prepared concrete or as a clear coat inside a multi-coat system.
Fast-curing
Recoat in 2 to 4 hours and walk on it in 4 to 8, built for limited-downtime jobs.
High solids
At 85% solids it builds a substantial, protective film in fewer coats.
Bonds to prepared concrete
Apply over diamond-ground concrete at ICRI CSP-2 with a moisture barrier, or within a multi-coat system.
Flexible and tough
40% elongation at break resists cracking, with 5,150 psi tensile and about 0.75 DCOF wet traction.

- Supplied clear, this kit is not pre-tinted and Latux does not stock color packs for it
Pairs with
Use EF-285 as the UV-stable primer and base coat under an Everflow polyaspartic or epoxy floor. Diamond grind concrete to ICRI CSP-2, prime with a moisture barrier such as EF-160 on damp slabs, then build your coating system on top.

What is EF-285 and what's it for?
It's a UV-stable, fast-curing aliphatic polyurea coating that works as a primer and base coat. Latux stocks it in clear, so use it as a UV-stable primer and base coat on prepared concrete or as a clear coat inside a multi-coat floor system.
Is EF-285 a polyaspartic or a polyurea?
It's an aliphatic polyurea, part of the same high-performance, UV-stable family. It won't yellow or chalk and provides superior abrasion, chemical, and UV resistance.
What color does it come in?
Clear. Latux sells EF-285 as a clear kit only. We do not stock pre-tinted versions or color packs for it. If the job needs a colored base coat, ask your Latux rep which system fits.
Can I apply EF-285 directly on concrete?
Yes, unlike the clear topcoats EF-275 and EF-280, EF-285 is designed to bond to prepared concrete. Diamond-grind to an ICRI CSP-2 profile and ensure the slab has a moisture barrier to prevent delamination.
How fast does it cure?
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, with full cure in roughly 7 days.
How much does one kit cover?
A 2-gallon kit covers about 400 sq ft at 8 mils.
How is EF-285 different from EF-275 and EF-280?
EF-285 is a clear polyurea primer and base coat that bonds directly to prepared concrete. EF-275 and EF-280 are clear polyaspartic topcoats applied over a finished base, not on bare concrete.
Why does my coating show tire marks?
Rubber tires can stain these coatings through plasticizer migration, and quick stops or starts can leave rubber burn marks. Use mats under parked vehicles where staining is a concern.
