Using Sealants

Sealants are used to fill gaps and joints.

When Choosing A Sealant, Ask Yourself

  • Is it an external or internal job? External jobs require weather-resistant sealant.
  • Is the area exposed to water? You'll need a water-resistant or waterproof sealant. Some are also anti-fungus and anti-mould.
  • Will you need to paint over the sealant?
  • Is the joint meant to move a lot? Silicone sealant has higher movement capability followed by co-polymer sealant.
  • What is the joint surface? Acid cure silicone sealant has excellent adhesion to glass and glass-like surfaces. Neutral cure silicones are more for general use.
