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.
Add the contents of the 2 inner tins to the outer tin. 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.
If appearance is critical we recommend the Application of a small trial area first.
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.
