Step 1: Apply a base coat of Blue Max® Liquid Rubber. This will be used to used to embed contouring fabric in the next step.

Step 2: Roll Contouring Roof Fabric™ into wet coating until the coating comes up through the fabric and saturates it. This is best done by laying the roll of fabric down and pushing it forward into the wet coating with a push broom or roller, excess coating will come up through the fabric. Avoid folds and wrinkles. Roll out the next course of fabric and repeat this process until the entire surface is covered in fabric. Allow to dry completely (24-48 hours).

Step 3: Apply an additional coat of Blue Max® over the surface to completely seal and fill all remaining pinhole openings in the fabric.

Once this top coat is dry, you can apply Ames Liquid Granite® for a beautifying waterproof finish or apply grout and tiles as you would normally

Estimated Coverage:
We recommend three gallons per 100 square feet for water containment. Shake or stir prior to use. The application must be applied in a continuous, unbroken seal of a minimum dry thickness of no less than 30 mils (the thickness of a dime). Two coats minimum, three to four is superior. More coats equal longer life. Rough surfaces will require additional product and drying time.

Weather & Drying Guidelines:
Both Ames® Blue Max® is best applied between 50° to 90° F (10° to 32° C) on warm dry surfaces. For exterior applications apply when the streets are dry, the sun is in the sky and no inclement weather is forecast. Starts to dry in 30 minutes to 2 hours, depending on thickness of application and weather. It continues to cure for up to 2 weeks. A slight tack is normal after drying. Ames® Blue Max® may be recoated or top coated when it is dry to the touch. Low temperatures, high humidity and evening and morning dew will require increased drying/curing time.
