Smith’s CRU ’86 — High-Gloss Urethane Topcoat

Smith’s CRU ’86 is a high-gloss, high-performance urethane topcoat that finishes a floor with a smooth, highly light-reflective shine — plus the UV stability, chemical resistance, and durability that industrial and decorative floors demand. A single-component, aliphatic, moisture-cured polyurethane at 86% solids, it’s the go-to gloss topcoat for aircraft hangars, showrooms, and metallic/luster decorative systems.

Gloss or Low Sheen — Your Choice

CRU ’86 goes on high gloss by default, but you can tailor the finish:

• High gloss — the standard, highly reflective finish

• Solid color — add Smith’s ISC Color Packs (sold separately)

Important to Know

CRU ’86 is a professional industrial topcoat with specific requirements:

• Requires a primer or coating system — not for direct application to bare concrete
• Dip-and-roll application — do NOT spray (emits harmful vapors when sprayed)
• Thin topcoat only — max 5 mils per coat; applying too thick causes blistering
• UV-stable, but does not block UV when applied clear over a non-UV-stable product (like epoxy)

Because it’s a demanding professional product, we’ll help you plan the primer, system, and application. Call us.

CRU ’86 vs. Hi-Wear 90S — Which Topcoat?

Two premium Smith’s urethane topcoats — the difference is mainly the finish:

• CRU ’86 (this one) — high gloss, single-component; ideal for showrooms, hangars, and showing off metallic/decorative floors
• Hi-Wear 90S — low sheen, maximum-longevity industrial topcoat for the heaviest-traffic floors

Want gloss and reflectivity? CRU ’86. Want a low-sheen, maximum-wear industrial finish? Hi-Wear 90S. Not sure? Call us and we’ll match the topcoat to your floor.
