#400 Del-Val Foundation Coating

Description: Del-Val 400 Non-Fibrated Foundation Coating is a non-fibrated asphalt coating that is used to prevent moisture penetrating through foundation walls and protecting a variety of roof surfaces. After the product is applied it forms a smooth flexible shell that helps resist the entrance of moisture through foundation walls. On the roof, Del-Val 400 Non-Fibrated Foundation Coating forms a weather resistant film that has excellent adhesion to most roof surfaces.

Uses: Del-Val 400 is used for exterior below grade masonry and block walls where no hydrostatic pressure is present. Used for coating all types of smooth surface asphalt roofs and can also be used to protect wood and metal above or below grade.

Preparation: All surfaces must be clean and free of any oil, grease, dirt and all other foreign matter. Must stir coating before using.

Application: Can be applied using: brush, roller, or heavy duty spray equipment. Allow 24 hours drying time before backfilling against the foundation walls. Do not apply over wet/damp or frost covered surfaces.
