Non-toxic, zero VOC, stain-block primer

Ecos Universal Primer is a water-based, solvent-free stain-block interior/exterior primer that's highly effective at blocking out many difficult stains such as rusted metal, rust stains, water stains on walls and ceilings and many other challenging stains. It's safe for everyone because it's made without solvents or hazardous chemicals and it contains no biocides or fungicides.

NOTE: This cannot be used over oil-based paints or sealers. For new drywall we recommend Ecos Drywall Primer. For priming raw wood we recommend Ecos Wood Primer. This product will not block tannin/oily/tarry stains, such as asphalt, or those from coal fires. Also, not suitable for cast iron, or bare iron or for pet dwellings or for use with plaster.

Ecos Universal Primer applies with brush or roller, leaving a beautifully smooth, even finish. Apply one or two coats depending upon the severity of the problem and always allow at least 6 hours between coats. One gallon over primed or painted surfaces covers approximately 400 SF per coat/gallon. Older, drier, or rougher surfaces will have a lower spread rate.

ECOS has industry-leading test performance and accreditations:

• The first North American paint manufacturer to complete the Health Product Declaration (HPD) — an open-standard format for accurate, reliable, and transparent reporting of product contents for LEED v4 that requires third-party certification;
• The only paint manufacturer with Declare Labels showing LBC Red List Free (a transparent ingredients labeling tool developed by the Living Building Challenge for manufacturers to fully disclose all intentionally added ingredients; Red List is a collection of worst-in-class building materials);
• The only professional-grade paint and primer certified to ASTM D-4236 (non-toxic);
• The only paint company with membership in the Juvenile Products Manufacturer’s Association (JPMA);
• The only paint company approved by the national non-profit Healthy Child Healthy World.
