ArmorRoof Asphalt Shingle Sealer is a unique clear 1-part sealer that protects and adds water resistance to roofs. Additional life/water resistance can be attained by using additional coats. We recommend a minimum of 2 coats, as most older/leaking roofs are ‘dry and porous’ and may tend to soak up the initial coat. Helps to prevent mildew and discoloration and reseal loose granules. Applies with a bluish cast, then dries clear. Apply down to 45 degrees F. Surface should be clean/dry/free from debris. Do not apply to wet or moist surfaces. Coverage approximately 1,250 square ft/5 gal pail. Can also be used on non-porous or painted surfaces for UV and weather protection.
