Roofing Sealant Quantec UDK-310-BR cartridge 310 ml brown

Quantec UDK-310-BR is a brown roofing sealant supplied in a 310 ml cartridge, formulated for sealing roof joints, flashings and overlaps on metal and bitumen surfaces. The cartridge fits standard caulking guns to enable controlled, continuous application along seams and edges. Intended for exterior use, the sealant creates a weather-resistant barrier that reduces water ingress and helps protect roofing assemblies from wind-driven rain and moisture.

Advantages

The product provides good adhesion to common roofing materials such as metal and bitumen, and the brown color blends with many roof finishes. Supplied in a cartridge compatible with standard caulking guns, it allows precise bead control and reduces material waste. The formulation is designed for outdoor exposure, offering elasticity to accommodate thermal movement and minor substrate deformation without losing the seal.

Suitable for

• Sealing roof joints and seams
• Weatherproofing flashings around chimneys, vents and skylights
• Sealing overlaps on metal and bitumen roofing
• Repairing small leaks and gaps in roof membranes

Key specifications

How to use

Ensure surfaces are clean, dry and free of dust, oils or loose material before application. Cut the cartridge tip to the desired bead size, fit into a standard caulking gun and apply steady pressure to lay a continuous bead along the joint or overlap. Tool the sealant within the product's skin formation time to achieve a smooth finish and good contact with the substrate. Allow the sealant to cure undisturbed according to ambient temperature and humidity conditions before exposing to heavy weather or foot traffic.

Usage recommendations

For best results, use on sound substrates and where temperature and weather conditions are within the manufacturer's recommended application range. Store cartridges in a cool, dry place and protect from frost prior to use. For large or structural repairs, combine with appropriate mechanical fastenings or consult a roofing professional.
