WaterTite Flexible Primer & Finish and Deep Tint
Base are high build, moisture and mildew resistant, low
VOC coatings designed with elastomeric qualities to
expand and contract to fill hairline cracks (1/16” or less) in
vertical concrete and masonry surfaces. These products
are suitable for stucco, brick, tilt-up walls, pre-cast or
poured-in-place concrete as well as CMU and cement
block. Flexible Primer & Finish and Deep Tint Base
provide excellent resistance to high alkali surfaces (pH
levels up to 13.8). These coatings can be applied to new
properly cast concrete and stucco within 72 hours. They
block efflorescence (salt build-up) from passing through
the topcoat and will not degrade when applied to concrete
surfaces with a pH of 13.8.
Durable and weather resistant, WaterTite Flexible Primer
& Finish and Deep Tint Base pass the ASTM D6904-03
Standard Practice for Resistance to Wind Driven Rain for
Exterior Coatings Applied on Masonry. Based on ASTM
1737-85 & D522 Method of Test for Elongation Testing,
Flexible Primer & Finish and Deep Tint Base can stretch
up to 160% and does not yellow or chalk. They can be
used as a primer or primer and topcoat. If used as a
primer, it is recommended to topcoat with a high quality oil
or latex-base topcoat or finish.

.PRODUCT APPLICATION .
SURFACE PREPARATION
Surfaces must be clean, dry, and sound. New concrete
must cure for at least 3 days prior to coating. Surfaces
must be free of dirt, efflorescence, mold, algae, sandy
mortar, release agents or any material that could
compromise the coating adhesion. Splash water on the
surface to test for the presence of form sealers or release
agents. If the surface turns dark, WaterTite Flexible Primer
& Finish can be applied. If the water beads up or does not
turn dark, the surface must be chemically or mechanically
cleaned and retest before proceeding. Wash, vacuum,
scrape, wire brush, power wash or mechanically abrade to
clean the surface.
PRODUCT APPLICATION (cont.) .
Cast concrete, concrete block and mortar joints must be
hard and firm-not loose, sandy or soft. Scrape the surface
with a flat screwdriver to test for soundness. If soft or
sandy, contact a professional contractor before
proceeding. Use mechanical means (hand or power tools)
to open holes (bug-holes) caused by air bubbles in cast-in-
place concrete to allow coating to fully penetrate. Replace
missing mortar and fill non-dynamic cracks and bug-holes
deeper than 1/16” with WaterTite Hydraulic Cement or
equivalent product. WaterTite Hydraulic Cement must be
fully dry before painting can begin. Follow the
manufacturer’s recommended dry time guidelines.
Flexible Primer & Finish and Deep Tint Base can be
applied over previously painted surfaces. However,
waterproofing ability is dependent upon the integrity and
moisture resistance of the previous coating.
WARNING! 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.
APPLICATION
Stir or mechanically mix thoroughly before and during
application. DO NOT THIN. Apply only when air, material,
and surface temperatures are between 50-90ºF (10-32ºC)
and the relative humidity is or less than 85%. To form a
continuous, pinhole free coating, apply evenly and
thoroughly. To use as a primer apply one coat. Apply two
coats to use as a primer and finish. Apply using a high
quality synthetic 3 to 4 inch brush, a ¾” nap roller. If rolled,
back brush to first coat to work the coating into the
concrete pores. It is more important to work the first coat
into the surface than for it to hide the substrate. Product
should be applied at a WFT of 10-12 mils (5-6 mils dry).
Use a wet film gauge to measure properly. Depending
upon the porosity of the substrate, apply the first coat at a
rate of 100-135 square feet per gallon. Apply the second
coat at a rate to complete the project. Flexible Primer &
Finish and Deep Tint Base can be applied with an airless
sprayer (tip size 0.017-0.021 with 2400-2900 psi). After
spraying, back roll to ensure uniform coverage.
