TCQCDG™ Expanding Foam Sealant – Gap & Crack Insulating Foam for Windows, Doors, Pipes, Vents & Wall Openings
TCQCDG™ Expanding Foam Sealant – Gap & Crack Insulating Foam for Windows, Doors, Pipes, Vents & Wall Openings
Seal difficult gaps and irregular openings with TCQCDG™ Expanding Foam Sealant—a ready-to-use insulating foam designed for everyday construction, renovation, and home-maintenance projects.
After application, the foam expands to reach into cracks and hard-to-fill spaces, creating a firm barrier around windows, doors, pipes, vents, cables, and wall penetrations. It helps reduce unwanted airflow, moisture intrusion, dust, outside noise, and energy loss caused by unsealed gaps.
The precision applicator straw makes it easier to direct the foam into narrow openings while reducing unnecessary waste. Once fully cured, the foam can be trimmed, sanded, shaped, and painted for a cleaner finished appearance.

How to Use
- Make sure the application area is clean and free from loose dust, grease, and debris.
- Protect nearby floors, walls, furniture, and finished surfaces.
- Wear protective gloves and safety glasses before application.
- Shake the container thoroughly according to the package directions.
- Attach the applicator straw securely.
- Hold the container in the recommended dispensing position.
- Apply a small amount of foam into the opening, starting at the deepest point.
- Fill only part of the gap because the foam will continue expanding.
- Allow the foam to expand and cure completely.
- Trim away excess cured foam with a suitable utility knife.
- Sand, paint, or cover the repaired area when needed.
Important Application Notes
Expansion and curing time may vary according to temperature, humidity, gap size, and application thickness. Avoid overfilling, especially around window and door frames, because excessive foam pressure may affect surrounding materials.
Outdoor cured foam should be painted, coated, or otherwise protected from prolonged sunlight and weather exposure.
Safety Information
Use only in a well-ventilated area. Wear gloves, protective eyewear, and suitable work clothing. Uncured foam is highly adhesive and may be difficult to remove from skin, clothing, and finished surfaces.
Keep away from heat, sparks, flames, and other ignition sources. Do not use around hot pipes, fireplaces, chimneys, or high-temperature equipment. This product is not a structural adhesive or firestop material and should not be used for fire-rated penetrations unless specifically tested and labeled for that purpose.
