Waypoint Sealants launches Black Mold Defender sealant for porous surfaces

Waypoint Sealants said June 9, 2026, it has launched Black Mold Defender (WPC-100), a silicone sealant designed to stop black mold, algae and moss on porous surfaces. The product is aimed at residential and commercial users who want a faster, longer-lasting alternative to pressure washing and repeated chemical cleaning.

Why it matters: - Black mold, algae and moss can damage property appearance, reduce value and create repeated maintenance costs. - Waypoint Sealants says Black Mold Defender is designed to create a long-term barrier on porous surfaces, which could reduce pressure washing, reapplication and chemical cleaning. - The product is positioned for both homeowners and property managers who need protection on masonry, concrete, roofs and other exposed surfaces.

What happened: - Waypoint Sealants announced the launch of Black Mold Defender (WPC-100) on June 9, 2026. - The product is an advanced silicone-based sealant intended to eliminate and prevent black mold, algae and moss on porous surfaces. - Rusk Jones, owner at Waypoint Sealants, said the product is a commercial-grade solution that locks out moisture and helps prevent organic discoloration.

The details: - Black Mold Defender bonds at a molecular level to form a seamless, invisible barrier. - The formula is designed to stop water and help slow the spread of Gloeocapsa magma, the microorganism linked to black streaks on masonry, concrete and roofs. - The company says the product works on wood, brick, stone and concrete without changing the surface appearance or adding gloss. - The sealant dries and cures completely in 30 to 40 minutes. - Once cured, the barrier is described as safe for landscaping, pets and family members. - The product is formulated for exterior and interior use. - Supported surfaces include natural stone, brick, concrete and stucco. - Other use cases include vinyl siding, wood framing, drywall, tile and grout. - The invisible barrier is designed to preserve the natural look and texture of the material without yellowing. - The sealant is manufactured in the U.S. - Black Mold Defender is sold directly through Waypoint Sealants in 2-quart and 5-gallon sizes. - The company also offers a professional registration program with savings on each purchase. - More information is available on Waypoint Sealants’ website and the professional registration page.

Between the lines: - The launch targets a common maintenance problem with a product that claims longer durability than topical cleaners and temporary coatings. - The emphasis on invisible protection suggests Waypoint Sealants is trying to preserve surface appearance while lowering upkeep costs. - The environmental pitch centers on less pressure washing and fewer chemical cleanings, which could reduce water use and runoff if the product performs as described.

What’s next: - Waypoint Sealants will likely push Black Mold Defender through direct online sales and its professional program. - The product’s market test will be whether contractors and property owners adopt it as a substitute for repeated cleaning cycles. - Demand will likely depend on how well the sealant holds up across indoor and outdoor surfaces over time.
