SURFACE
PREP
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
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.
APPLICATION
Wet
surface to be patched with clean water. When repairing small cracks
apply DRYLOK Concrete Patch with a stiff brush. After approximately
10 minutes, remove excess material by scraping with putty knife. For
deep or wide repairs apply patch with a putty knife or trowel.
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.
