What You Need

  • Selleys No Mould
  • Caulking gun
  • Utility knife – a small, sharp blade makes cleaning edges safe and easy
  • Rounded spatula
  • A clean rag 
  • Mineral turpentine

Easy as..

  1. Clean your workspace so that it’s free from dust and debris. If necessary, cut away or remove any existing silicone. Contaminants will prevent a decent bond, so wipe over the area with some mineral turps.
  2. Load the Selleys No Mould cartridge into your caulking gun.
  3. Hold the sealant tip at a 45 degree angle and apply the silicone evenly and with a steady hand. When you reach the end of the area you want to seal, release the lever to stop the flow of silicone.
  4. Use a damp finger or rounded spatula to wipe off any excess product to ensure a smooth, clean finish. Allow the silicone to cure before exposing to water (approximately 72 hours).
  5. Clean up any excess and tools with mineral turps before the product cures. 

Handy Tips

  • For neater joints, mask sides before applying sealant and remove tape before sealant skins.
  • Keep sealant cleaned regularly to avoid the build-up of soap scum.
