Uses: protection to metal tanks, pipes etc. Can be used to protect metal and concrete structures prior to sinking into earth or water.

New easier to apply formula with glass reinforcement for even greater resistance to chemical attack

Suitable for internal and external use

Can be applied to damp surfaces

Excellent resistance to petrol, diesel, acids, alkalis and solvents (see datasheet)

Fills cracks between bund wall and floor

Flexible chemical and waterproof coating

Can be used with Watco Fibreglass Reinforcing Tape to fill cracks and joints between bund wall and floor

Watco Bund Sealer is a two part thick epoxy resin. One coat is generally enough to achieve a waterproof seal that is highly chemical resistant.

Coverage approx. 4.5–6m² per 3kg per coat. One coat is normally sufficient.

Surface Preparation
Ensure surfaces are clean, sound and free of contaminants. Large cracks in the surface should be repaired prior to application of Watco Bund Sealer. Minor cracks and joints can be bridged by Bund Sealer with Watco Fibreglass Reinforcing Tape. Remove grease and oil using Watco Bio D.
Watco Bund Sealer can be applied to damp surfaces, although for more permanent installations we recommend that the surface is as dry as possible. Watco Bund Sealer can be applied to painted surfaces but all loose or defective paint should be removed first. Remove loose rust from metal (it is not necessary to remove all ‘well bonded’ rust). Heavily corroded, very rusty metal can be primed with Watco Primebase.


Mixing
Add the contents of the curing agent to the resin. Part mixing is not recommended. Using a flat bladed palette-knife or similar tool, scrape all the material from the inside of the tins and mix thoroughly.

Application
Apply by brush, working well into the substrate. The product can be brushed thickly over hairline cracks and joints. One coat is generally sufficient to produce a watertight seal. A second coat may be required on very porous surfaces or to produce a continuous film over rough surfaces.
