Steel-It Polyurethane Topcoat Quart 1002Q
STEEL-IT 1002Q is a steel gray one-component polyurethane topcoat in a quart with 316L stainless leafing pigment for metal and fab work. It goes direct-to-metal and leaves a finish with UV protection, washdown resistance, and later weldability.
- Protects steel and aluminum against corrosion, abrasion, salt spray, and harsh chemicals.
- Stays weldable after a full cure for TIG or MIG without stripping the finish first.
- Coverage is approximately 152 sq ft per gallon at 3 mils DFT on smooth metal.

STEEL-IT 1002Q Steel Gray Polyurethane Topcoat - Quart
STEEL-IT 1002Q is a steel gray one-component polyurethane topcoat in a quart loaded with 316L stainless leafing pigment. It goes direct-to-metal on steel, galvanized, and aluminum that need corrosion and UV resistance, and after a full cure the finish stays weldable for TIG or MIG on plant and fab equipment that sees weather, washdown, and abrasion outdoors and inside.

Key Features
- STEEL-IT 1002Q is the quart of steel gray polyurethane topcoat with 316L stainless leafing pigment.
- Direct-to-metal placement covers steel, galvanized steel, aluminum, and common fab substrates.
- The cured film resists corrosion, abrasion, UV, moisture, salt spray, and harsh chemicals.
- A full 7-day cure keeps the finish weldable for TIG or MIG with matching aerosol touch-up.
- The standard system builds two coats at approximately 3 mils DFT each for 6 mils total.
- STEEL-IT 2213 Epoxy Ester Precoat under the topcoat adds corrosion resistance when welding is not planned.

Frequently Asked Questions
What metals and jobs is STEEL-IT 1002Q made for?
STEEL-IT 1002Q is the steel gray polyurethane quart for fab, plant equipment, motorsports, marine, and outdoor metal that needs UV and corrosion resistance. The TDS names steel, galvanized steel, aluminum, copper, brass, plastic, and fiberglass.
What film build does the liquid topcoat system need?
The TDS calls for two coats of STEEL-IT 1002 at approximately 3 mils DFT each (6 mils total). Harsh service can use three coats for approximately 9 mils total. One coat at approximately 9 mils wet film targets approximately 3 mils DFT.
What temperature window applies when placing STEEL-IT 1002Q?
Apply at 50 F to 100 F (10 C to 38 C) with relative humidity under 85 percent and the substrate at least 5 F above dew point. Dry to touch is approximately 2 hours; recoat window is 4 to 24 hours. Full cure is 5 to 7 days.
What cure time is required before welding through STEEL-IT 1002Q?
TIG or MIG after a full 7-day cure. Touch-up with STEEL-IT steel gray polyurethane aerosol. When welding is not planned, STEEL-IT 2213 Epoxy Ester Precoat under the topcoat improves corrosion resistance.
Which other STEEL-IT packs match this steel gray polyurethane chemistry?
Live sisters are the Gallon 1002G, the 12 oz aerosol 1002D, and Black quart 1012Q. Same steel gray polyurethane family as the 1002 TDS column.
What coverage and solids does the liquid TDS list?
Approximately 152 sq ft per gallon at 3 mils DFT on smooth metal (20 percent overspray assumed). Solids approximately 46 percent by weight and 38 percent by volume. Weight approximately 9.8 lb/gal. Max in-service temperature 200 F (93 C). VOC approximately 3.8 lb/gal (460 g/L).
