Sealant Warmtec Butyl 200, 580 ml bag — butyl-based joint sealant

Warmtec Butyl 200 is a butyl-based joint sealant supplied in a 580 ml bag. Supplied as a paste-like compound, it is intended for creating flexible, water-resistant seals and bonds on construction elements. The formulation maintains elasticity after application, providing durable sealing for seams, overlaps, flashings and roof details where movement or thermal cycling may occur.

Advantages

Warmtec Butyl 200 offers long-term elasticity and strong adhesion to common building materials such as metal, bitumen, and many plastics. Its paste consistency allows both manual application and use with appropriate bag applicators, enabling controlled bead formation and reduced waste. The water-resistant nature of the butyl composition ensures reliable protection against moisture penetration in roofing, gutters and exterior joints.

Suitable for

• Sealing overlaps and seams on roofing membranes and metal sheets
• Bonding and sealing flashings, gutters and downspouts
• General construction joints subject to movement or vibration
• Repairing leaks and creating watertight connections in exterior details

Key specifications

• Base: butyl rubber compound providing permanent elasticity
• Form: paste-like putty supplied in a 580 ml bag for applicator or manual use
• Color: neutral (consult product label for exact shade)
• Application temperature range: suitable for typical construction site conditions (see label for exact limits)
• Resistance: water-resistant after application; suitable for exterior exposure on roofs and gutters
• Curing: remains physically tacky/elastic rather than curing to a hard film

How to use

Prepare the surfaces by ensuring they are clean, dry and free of loose debris, dust or oils. Cut the bag tip or mount the bag into a compatible applicator, then apply an even bead of butyl compound to the joint, overlap or flashing. Press or tool the material to ensure contact over the full joint width and to remove entrapped air. On larger overlaps or vertical surfaces, support the joint until the compound has achieved adequate adhesion. Avoid applying over wet or frozen substrates and follow the manufacturer's safety instructions on the product label.

Usage recommendations

For best performance, apply Warmtec Butyl 200 at temperatures within the range recommended on the product label and store unopened bags in a cool, dry place. When bonding dissimilar materials, test adhesion on a small area first. Use suitable personal protective equipment and follow local regulations for disposal of used packaging.
