sealant

Sealant is a substance used to block the passage of fluids through the surface or joints or openings in materials, a type of mechanical seal. In building construction sealant is sometimes synonymous with caulking and also serve the purposes of blocking dust, sound and heat transmission. Sealants may be weak or strong, flexible or rigid, permanent or temporary. Sealants are not adhesives but some have adhesive qualities and are called adhesive-sealants or structural sealants.

    Chocolate Brown Sealant

    Any ideas where I could find a very dark brown silicone (or other) sealant. To seal and fill behind some laminate worktop in a bathroom. Not really in a wet area - so doesn't need anything special. Just something that will fill. Most importantly it needs to be as dark a brown as possible. Paul
