Description:
Heavy-Duty, Portland cement-base, waterproofing
coating for sealing, protecting & decorating walls
and surfaces constructed of poured concrete,
concrete/cinder block , masonry, stone, brick or
stucco. Safe coating for sealing the inside of
drinking water concrete tanks and cisterns. Easy
to use; just add water (plus Damtite Bonding
Additive for previously-painted or non-porous
surfaces) and mix. Eliminates dampness; resists
mold/mildew & flaking/chalking while beautifying
and sealing all pores & voids.
Unlike ready-mix paints which can only be
applied to dry surfaces, this product is made for
use on wet or dry surfaces. It withstands over
22psi of hydrostatic pressure (equal to holding
back a 48 foot high wall of water). Plus, it is
breathable, so moisture does not get trapped
behind the surface. It also reduces Radon Gas
infiltration. Not formulated to withstand foot
traffic. Tip: Wear protective gloves and goggles.
Surface Preparation:
Most important step for best waterproofing results
and adhesion. Clean the surface thoroughly with
wire brush to remove any loose mortar, paint, dust,
grease or oil. Then, follow our Step 1-2-3 Project
Guideline: Step 1-Prepare the Surface: Remove
powdery, salt-like, alkaline deposit (efflorescence)
or form-oil residue with Damtite Concrete
Cleaner. After 20-30 minutes, rinse surface well
with water. Step 2-Repair the Surface: Fill holes,
cracks or active water leaks and mortar joints with
Damtite Hydraulic Cement. Step 3-Decorate
& Waterproof: Apply two coats of this product.
Important: using garden sprayer, hose set to fine
mist or brush, completely dampen surface with
clean water immediately prior to applying and
keep surface wet during application.
WARNING! If you scrape, sand, or remove 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.

Mixing:
Since the mix will harden within 1 hour, mix not
more than ½ of the powder or 25 lb (11,3 kg). For
porous bare surfaces (concrete or cinder block):
First add 3.5 quarts (3,3 L) of clean water into a
clean mixing container. Then gradually add 25
lb (11,3 kg) of powder while stirring constantly
to a “pancake batter” consistency, using a paint
stirrer or attachment to electric drill. For smooth,
non-porous bare surfaces (poured concrete, stone,
unglazed terra-cotta, tile or brick) or previously-
painted surfaces: add Damtite Bonding Additive
as replacement of water. Depending upon surface
conditions, for each 25 lb (11,3 kg) of powder, use
total liquid as either 2 quarts (1,9 L) of Additive
plus 1½ quarts (1,4 L) of water or replace all water
with 3½ quarts (3,3 L) of Additive. Keep powder
to total liquid at 2.5 to 1 ratio. For smaller quantity
mixes, add 2.5 parts powder to 1 part total liquid.
Allow mix to set undisturbed for 15 minutes to
activate the waterproofing agents before applying.
During application, stir often. To prevent hardening,
add a little water if needed. After 1st application,
clean mixing pail. Repeat same steps for 2nd coat.
Application:
TWO-COATS REQUIRED FOR BEST RESULTS &
WARRANTY. Apply with a nylon paint brush or
roller. Insure surface is uniformly pre-wetted &
dampened with clean water before applying each
mix. Start at top of wall in corner and work down
wall, applying liberal amount of product, brushing
first coat in different directions to penetrate & fill
pores, pinholes and hairline cracks. Smooth out
the second coat by lightly brushing in one direction
across wall. To avoid lap marks, complete from
corner to corner in one application. Allow first coat
to dry 24-48 hours (or longer in unventilated or
severe leaking areas). Dampen surface lightly with
clean water prior to applying second coat. Follow
same procedures to apply second coat.
Limitations:
• Do not apply to frosted surfaces or when surface
temperature is below 50°F (10°C) within 48-72hrs.
• If applying to exterior surfaces during high
winds, direct hot sun or high temperatures, each
coat must be sprayed with fine, low pressure mist
of clean water 2-3 times/day to prevent drying too
quickly, which will cause cracking.
• May not perform as well over previously painted
surfaces, field/sandstone, or glazed tile/brick, so
first apply small sample test area.
Coverage:
1st coat over bare smooth/non-porous surface or
2nd coat application: Up to 350 sq ft (32,5m²). 1st
coat over rough/porous surface: approximately
280 sq ft (26,0m²).
Clean-Up/Storage/Disposal:
Wash hands & tools with soap & water
immediately after use. Store unused powder
tightly sealed in original container. Dispose of
hardened product in accordance with local, state &
federal requirements.
