Dowsil Adhesives, Sealants & Fillers Features and Benefits

• Silicone-based formulations: stay flexible after curing, so joints can move with the building without cracking or splitting.
• Weather and UV resistance: suited to external glazing and cladding joints that face rain, sun and frost year-round.
• Strong adhesion: bonds to common building surfaces such as glass, metals and many plastics, giving a lasting seal. Always check the product datasheet for substrate compatibility.
• Professional-grade finish: cures to a neat, consistent seal that suits visible joints where appearance matters.
• Compatible with sealant guns: cartridge formats work with standard applicators for controlled, tidy application.

Frequently Asked Questions

How do I choose the right Dowsil sealant for my job?

Start with the surfaces you are sealing and where the joint is located. Check whether it is internal or external, how much movement to expect and which materials are involved. The product datasheet will confirm compatibility, cure time and any primer requirements.

How do I get a neat finish when applying silicone sealant?

Clean and dry the joint first, and use masking tape for crisp edges. Cut the nozzle to suit the joint width and apply steady pressure with a quality sealant gun. Tool the bead promptly, then remove the tape before the sealant skins over.
