Zero VOC semi-gloss paint with 36% solids content that delivers professional-grade durability at 325-375 square feet per gallon practical coverage. For Montana contractors dealing with tight winter interiors and occupied spaces, the <= 5 g/L VOC content means crews can paint without evacuating homeowners or dealing with odor complaints.
Zero VOC Performance That Works in Montana Winters
VOC content at or below 5 grams per liter qualifies this as truly zero VOC. Not “low VOC” marketing speak — actual zero. When you’re painting a Kalispell kitchen in January with windows sealed tight against -10°F weather, that matters. Dry to touch in 30-60 minutes, ready for second coat in 1-2 hours. Those fast dry times work both ways in Montana’s low humidity — less time for lap marks to develop, but also less open time for blending.
The 100% acrylic copolymer resin handles temperature swings better than cheap vinyl-acrylic blends. At 40-50% gloss measured at 60 degrees, it hits the sweet spot for semi-gloss — enough sheen to wipe clean without looking plastic.
Superior block resistance prevents that sticky feeling when painted doors and windows meet their frames. In a climate where houses expand and contract with 100-degree temperature swings between summer and winter, block resistance isn’t optional.
Coverage Numbers That Add Up
| Specification | Value | Source |
|---|---|---|
| Coverage | 325-375 sq ft/gallon | Manufacturer |
| Solids by Volume | 36% +/- 2% | Manufacturer |
| Solids by Weight | 47% +/- 2% | Manufacturer |
| Weight per Gallon | 10.34 lbs | Manufacturer |
| Film Thickness (wet) | 4.2 mil per coat | Manufacturer |
| Film Thickness (dry) | 1.5 mil per coat | Manufacturer |
36% volume solids puts real paint on the wall, not just water and air. At 1.5 mil dry film thickness per coat, two coats build the 3-mil film needed for durability in high-traffic areas. 325-375 square feet per gallon practical coverage means a 5-gallon bucket covers 1,625-1,875 square feet — enough for most residential rooms in two coats.
What Surfaces It Sticks To
Good adhesion to aged alkyd paints solves a real Montana problem. Half the homes built before 1980 have oil-based trim paint that modern acrylics won’t grip. Spartawall sticks without extensive sanding or priming.
Surface must be clean, dry, and free of grease, oil, wax, and mildew. Remove loose paint and sand glossy surfaces to promote adhesion. Repair cracks and sand smooth. Standard prep work — nothing special required.
Compatible surfaces include drywall, masonry, wood, and metal. On new drywall, it’s self-priming. For Level 4/5 finishes, use Vinylastic Plus primer. Masonry needs Eff-Stop Premium or Select. Wood trim takes Decoprime. Metal requires Bloc-Rust Premium or Ultra-Grip Premium.
Professional Application
Tools include synthetic brush, roller, or airless sprayer. Exceptional leveling for a smooth surface with easy application and minimal spatter. The 92-98 KU viscosity at 77°F flows off the brush without running.
Normally no thinning needed. If required, add up to 4 fl oz clean water per gallon. Montana’s dry air might require that touch of water to maintain workability, especially in heated winter interiors.
Cleanup with warm, soapy water. No mineral spirits. No ventilation requirements beyond normal airflow.

The Bottom Line
For Montana contractors who need to paint occupied spaces in winter, Spartawall Semi Gloss delivers. Zero VOC formula keeps customers happy. Good adhesion to aged alkyd paints saves prep time on repaints. Superior block resistance prevents callbacks when doors start sticking come spring.
The durable and scrub-resistant finish compared to Behr suggests this isn’t bottom-shelf paint rebadged. At 36% volume solids, it puts enough paint on the wall to last. Dunn-Edwards provides a standard limited warranty against product defects — not lifetime coverage, but standard protection for a commercial-grade product.
FAQ
Q: How many coats do I need on new drywall?
A: Self-priming on new drywall, so typically two coats total. Each coat builds 1.5 mil dry film thickness, giving you 3 mils total — sufficient for most interior applications.
Q: Can this go directly over oil-based trim paint?
A: Good adhesion to aged alkyd paints means it often can, but sand glossy surfaces to promote adhesion. Test a small area first.
Q: What’s the actual working time before it starts to tack up?
A: 30-60 minutes to touch dry depending on temperature, humidity, and film thickness. In Montana’s dry air, expect the faster end of that range.
Q: Is this actually zero VOC or just low VOC?
A: VOC content <= 5 g/L meets the strictest definition of zero VOC. No added organic solvents.
Q: What sheen level should I expect?
A: 40-50% gloss at 60 degrees puts it firmly in semi-gloss range — more sheen than satin, less than full gloss.
