Product information

Description

Transparent silicone rubber sealant spray K2 B441 in a 400 ml aerosol can provides a flexible waterproof coating for exterior joints and seams. Formulated for use on gutters, chimneys, roofs and similar exposed areas, this spray creates a transparent layer that adheres to common building materials and resists rain and moisture. The aerosol format allows precise application in hard-to-reach spots and supports quick, temporary or permanent repairs without the need for manual mixing.

Advantages

The silicone rubber formula delivers elasticity that accommodates thermal movement and prevents cracks. Transparent finish preserves the appearance of surfaces while sealing gaps and protecting against water ingress. The aerosol application ensures even coverage and fast curing, enabling efficient work on vertical and overhead surfaces. Suitable for direct use outdoors, it bonds to metal, tile, concrete and many synthetic materials when surfaces are clean and dry.

Suitable for

  • Sealing joints and seams on gutters and downpipes
  • Repairing leaky spots around chimneys and flashing
  • Sealing roof tiles, ridges and overlaps
  • Weatherproofing exterior connections on vents and fittings
  • Temporary or localized waterproof repairs on metal and masonry

Key specifications

  • Form: aerosol spray, 400 ml can
  • Material: transparent silicone rubber sealant
  • Application: outdoor use on roofs, gutters, chimneys and similar surfaces
  • Properties: flexible, waterproof, weather-resistant seal
  • Adhesion: suitable for metal, tile, concrete and many plastics (surface-dependent)
  • Curing: surface skin formation and curing time dependent on temperature and humidity

How to use

Prepare surfaces by removing loose debris, dust, oil and frost; ensure the area is dry for optimal adhesion. Shake the aerosol can thoroughly before use and test spray on a small inconspicuous area. Hold the can upright at the recommended distance and apply an even coat to the joint or damaged area, building up layers if greater thickness is needed. Allow adequate curing time between layers and after final application, following environmental conditions such as temperature and humidity for proper cross-linking.

Usage recommendations

For best results, apply at moderate temperatures and avoid use during rain or when surfaces are wet. Use personal protective equipment such as gloves and eye protection and ensure adequate ventilation when applying in confined spaces. Store the aerosol upright in a cool, dry place away from direct heat sources and open flames.
