Read all label instructions before beginning. Always run a test patch first in an inconspicuous area to ensure that proper adhesion and drying occurs and the product works to your satisfaction. Careful and complete preparation will ensure the best results and contribute to the life of the coating. The wall surface must be clean, dry, and free of loose material. Loose or peeling paint should be removed with a wire brush and rough wood surfaces sanded. Metal or concrete surfaces may be prepared by using a disc grinder and carborundum disc. Care should be taken so as not to grind though the metal. Do not apply Ames’® Block & Wall™ over wet, loose or crumbling concrete. Repair the concrete and allow to cure. Mildew may be removed with a power washer. All major cracks, joints and seams should be caulked with Ames® Blue Max™ trowel-grade liquid rubber. Do not use a silicone caulk. It is important to use Ames® Seam Tape on all joints and cracks to avoid future cracking and leaking. Apply around flashings, windows and cracks in the walls. Mask all sensitive areas before applying coating.

Weather & Drying Guidelines:
Ames’® Block and Wall™  is best applied between 40° to 90° F (10° to 32° C) on warm dry surfaces. Apply when the streets are dry, the sun is in the sky and no inclement weather is forecast. Starts to dry in 2-8 hours, depending on thickness of application and weather; allow at least 24 hours to cure. Low temperatures, high humidity and evening and morning dew will require increased drying/curing time.
