Use and Care Manual
Our Flood Protection products are specically designed to work together to create multiple layers of
super-strong, waterproof protection, and to be easily removed after oodwaters recede. They can
help slow down or even stop water from entering structures. Whether you’re sealing a door, window
or crawl space, the concept remains the same—seal all openings where water may enter using
multiple layers of our Flood Protection products.
Apply to the exterior of the structure. NOT DESIGNED TO PROTECT AGAINST EXTREME
WINDS, WATER PRESSURE, FLYING OR FLOATING DEBRIS. NOT INTENDED TO STOP WATER
FROM FLASH FLOODS OR IF THERE IS STRUCTURAL DAMAGE TO THE BUILDING.
BEFORE YOU GET STARTED…
Always follow State and Local weather advisories and evacuation orders. Floods can be
catastrophic and life-threatening.
Every structure is dierent. Depending on the age and type of construction, there may be areas
that can’t be seen or sealed. So, it’s impossible to stop all oods from entering every time, but our
Flood Protection products can help. Unsealed porous surfaces may seep water during extended
underwater exposure.
Be prepared to leave if sealing the entire structure. Once your nal entry point is sealed, you will
not be able to re-enter without breaking the seal of your Flood Protection products.
FOR BEST RESULTS
• Read all product labels in full and follow all instructions and safety warnings.
• Depending on the opening, we recommend using our FLOOD PROTECTION PASTE IN A
CARTRIDGE as a base coat for your rst layer of protection and our FLOOD PROTECTION
LIQUID or SPRAY as a nal coat to help seal any small openings or pinholes that may have been
missed. When used in combination, they create multiple layers of waterproof protection.
• Proper surface preparation is extremely important. Remove debris, being cautious of sharp
objects that could cause injury, such as glass, nails, etc. Make sure all areas are clean, dry, and
free of grease, oil, dirt, and debris.
• Apply even layers of Flood Protection products, with each coat being wider and overlapping the
previous one. All openings should be sealed a minimum of one foot above anticipated water level.
• When using Flood Protection Liquid, be sure to keep brush wet and always use fresh product.
• If sealing your primary entry/exit, all persons, pets, and essential belongings must be removed
from premises. You will not be able to re-enter without breaking the Flood Protection seal.
• Wait until products are dry to the touch before applying additional layers.
• Allow 24-48 hours for your nal coat of Flood Protection products to dry before oodwaters arrive.
