Category Information

Sealants are not designed for strength, but more to block gases and liquids from passing through an area, such as a joints or opening in a surface or between several surfaces. They can be used to block:

  • Drafts
  • Water (such as in a bathroom or preventing rain water getting into a building)
  • Sounds
  • Dust
  • Heat

They are not – effectively – adhesives, however many of them do have adhesive-type properties, and depending on the type of sealant that you choose and for what purpose, they can be either rigid or flexible.

At Howarth Timber & Building Supplies, we offer a variety of top-quality Sealants, such as:


  • General Purpose
  • Weatherproof
  • Sanitary
  • Fire & Heat
  • Removers
  • Glazing
  • Building
