Medallion Semi-Gloss Exterior Paint Black: 2-Hour Rain Protection That Actually Works

Medallion Semi-Gloss Exterior Black delivers the fastest rain protection in the acrylic paint market. 2 hours to rain-ready versus the standard 4-8 hours contractors typically plan around. That two-hour window changes everything for Montana’s afternoon thunderstorm season.

This 100% Acrylic Latex (Water-based) formula combines legitimate weather resistance with the coverage and workability contractors need. The semi-gloss sheen handles trim work, doors, and high-moisture areas where flat finishes would show every water mark.

Rain Ready Technology and Application Specs

Rain Ready® Technology (resists rain in 2 hours) sets this paint apart from standard exterior acrylics. Once applied, the coating develops water resistance fast enough to survive Montana’s unpredictable weather patterns. The paint provides water resistance once applied and specifically resists water, runs, blisters, and water marks.

Specification	Value
Coverage	250 – 400 sq. ft. per gallon
Application Temperature	40°F – 90°F (4.4°C – 32.2°C)
Touch Dry	1 – 4 hours (at 77°F, 50% RH)
Recoat Time	2 – 4 hours (at 77°F, 50% RH)
Rain Ready	Approx. 2 hours
Specific Gravity	1.04
Viscosity	20.5 cSt
pH Level	9

The 40°F minimum application temperature works through Montana’s painting season from late April into October. That’s practical for a state where nighttime temperatures can drop even in summer. The Ultra-Flexible Formula (resists cracking and peeling) handles the thermal cycling between Montana days and nights without failing at the substrate interface.

Substrate Compatibility and Professional Performance

Medallion covers the full range of exterior surfaces contractors encounter. Compatible substrates include Wood, Hardboard siding, Aluminum siding, Vinyl siding, Masonry, Brick, Stucco, Cement-composition panels, and Primed Metal.

That substrate range eliminates the need to stock multiple specialty paints. One product handles the wood trim, the fiber cement siding, and the primed metal door. For contractors juggling multiple projects, that versatility matters.

The paint also features Mold & Mildew Resistant Finish — critical for Montana’s valley locations where morning fog and high humidity create ideal conditions for organic growth. The manufacturer backs this with a Limited Lifetime Warranty; details: Covers product failure to original purchaser on application property.

Surface prep remains non-negotiable: Clean surface, remove loose paint, sand glossy areas, and spot-prime bare/tannin woods. Application works with standard methods — Apply via brush, roller, or sprayer; stir thoroughly; intermix multiple containers. Cleanup uses warm, soapy water; do not pour down drains.

California Proposition 65 Warning: Contains Carbon Black and Cristobalite. VOC compliance meets current regulations.

Professional contractors give this paint strong marks — 4.9 average rating across 58 reviews. Users specifically mention that it Covers well in one coat on many surfaces and Dries fast and is easy to work with.

FAQ

What makes the 2-hour rain protection different from standard exterior paints?

Standard acrylic paints need 4-8 hours before they can handle moisture. Medallion’s Rain Ready technology cuts that to 2 hours, which means painters can work right up until afternoon storms roll in. The coating resists water marks, runs, and blisters once that 2-hour mark hits.

Can this paint handle Montana’s freeze-thaw cycles?

The Ultra-Flexible Formula specifically resists cracking and peeling from temperature swings. Combined with the 40°F minimum application temperature, it’s engineered for climates with dramatic day-night temperature differences.

What surfaces can I skip with this paint?

Do not use on glazed brick, glazed aluminum, glazed masonry, floors, or steps. The paint needs a porous surface to properly adhere — glazed surfaces won’t provide the mechanical bond necessary for long-term performance.

How does the semi-gloss sheen compare to other finishes for exterior use?

Semi-gloss provides better moisture resistance than flat finishes while hiding surface imperfections better than full gloss. It’s the sweet spot for trim work, doors, and areas that see frequent moisture exposure. The sheen level also makes cleaning easier when dirt or mildew does accumulate.
