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).
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.
Extensive testing is what makes us the most highly qualified paint and repair manufacturer on the market. Our tests cover just about everything you might want to know about a floor coating – how well it bonds to the floor, how durable it is, how well it stands up to scratching and much more.
