The area to be repaired must be clean and free from all dirt and loose material. DRYLOK Concrete
Patch will not adhere to crumbly or powdery surfaces. If area to be patched has been washed, mop up excess water.
Mix DRYLOK Concrete Patch right in DRYLOK Concrete Patch container. Wear a dust mask to avoid breathing dry powder. Slowly add water to the special cement powder (1 part water to 3 parts cement for normal repairs) stirring constantly until the consistency is smooth. Adjust consistency if necessary by adding additional water or cement powder. To repair small cracks, mix to a thin consistency; for deep or wide repairs, use a heavy consistency.
If you scrape, sand, or remove old paint, you may release lead dust.
LEAD IS TOXIC. EXPOSURE TO LEAD DUST CAN CAUSE SERIOUS ILLNESS, SUCH AS BRAIN DAMAGE, ESPECIALLY IN CHILDREN. PREGNANT WOMEN SHOULD ALSO AVOID EXPOSURE. Wear a NIOSH- approved respirator to control lead exposure. Clean up carefully with a HEPA vacuum and a wet mop. Before you start, find out how to protect yourself and your family by contacting the National Lead Information Hotline at 1-800-424-LEAD or log on to www.epa.gov/lead.

DRYLOK Concrete Patch should be used within two hours after mixing. Even though DRYLOK Concrete Patch provides better adhesion than other types of repair materials, the reopening of patched areas due to settling and expansion or contraction can occur. Do not use in temperatures below 40°F. To strengthen the bond of DRYLOK Concrete Patch to difficult surfaces such as dense or slick concrete, coat surface with DRYLOK Latex Bonding Agent instead of water before patching. Apply DRYLOK Latex Bonding Agent by brush or spray. Wait for it to change from milky color to a clear glaze (approx. 30 minutes) before applying patch.
