Preparation

Surface must be clean and free of dirt, dust, oil or grease and be free of any other foreign matter that would interfere with good adhesion. In colder climates we recommend storing the product at room temperature for 24 hours prior to application. Do not apply in ponding water or when water is present.

Application

Apply with a trowel or putty knife. Spread Del-Val 232 to approximately 1/8” thickness and work thoroughly into the problem area. Repairing cracks and blisters: if the area is 1/4” wide to 2” long, apply United Asphalt Cotton or Fiberglass Fabric for reinforcement then cover with additional cement.
