Red Devil 0920 Expanding Polyurethane Foam Sealant 20 Oz

Product Description

The RED DEVIL 0920 is a minimum-expanding polyurethane foam sealant formulated to fill cracks, gaps, and small voids in walls, floors, and around penetrations. The foam expands on contact with moisture and cures to a firm, paintable bead that can be trimmed or sanded after set. At 20 oz per can, it delivers enough volume for a full day of sealing work on typical residential or light commercial jobs. Cure requires both ventilation and ambient humidity, so the work area must have airflow. Licensed HVAC techs, plumbers, and general contractors reach for this product when sealing around pipe penetrations, conduit sleeves, and framing gaps prior to insulation or drywall.

This foam sealant is suited for residential construction, remodeling, and mechanical rough-in work where small voids need to be filled and air-sealed before inspection. It is a minimum-expanding formula, making it appropriate for use around window and door frames, electrical boxes, and pipe chases where excessive expansion could cause structural distortion. The product is applied with a straw applicator directly into the void and expands in place as it contacts moisture in the air and substrate.

Key Features

• Minimum-expanding formula prevents over-expansion in confined framing cavities
• Polyurethane construction bonds to wood, masonry, metal, and most plastics
• Cures with ambient humidity — no primer or activator required
• Trimable and sandable after cure for clean finish
• 20 oz can size suitable for multi-penetration seal-out on a single job

Compatibility

Designed as a general-purpose gap and crack filler for use in residential and light commercial construction applications involving wood framing, masonry, concrete block, metal stud, and common substrate materials found around pipe and conduit penetrations.

Installation Notes

Apply in a well-ventilated area — do not use in enclosed spaces without active airflow. Wear chemical-resistant gloves, as uncured polyurethane foam bonds aggressively to skin and clothing. Shake the can thoroughly before use and apply with the straw tip inserted into the void. Allow full cure before trimming; cure time varies with ambient humidity and temperature.
