.DESCRIPTION AND USES .
WaterTite
®
LX Mold & Mildew Proof Waterproofing Paint is a
modified acrylic copolymer concrete and masonry waterproofing
paint and finish. It is designed to form an impermeable barrier to
water on interior and exterior, vertical or horizontal, concrete
block (not lightweight block) and cast-in-place concrete. It stops
moisture from entering basement or cellar walls and stops water
from exiting when applied to canals or holding basins. It is ideal
for use on fountains, reflecting pools, planters, retaining walls,
privacy fences, and more
It is an excellent block filler for use in wet areas where epoxy
finishes are to be applied, such as car washes, restrooms, etc. It
is not recommended for use in swimming pools or use in contact
with potable water. WaterTite LX meets ASTM D-7088
Resistance to Hydrostatic Pressure and ASTM D-6904
Resistance to Wind Driven Rain.
FEATURES
Water-based, very smooth, bright white, very low odor
Paintable with latex, oils, epoxies
Easy soap and water clean up
Fast drying – recoat in 2-3 hours
Covers 100 square feet per gallon.

APPEARANCE .
WaterTite LX produces a very smooth, bright white finish.
It can be tinted to off-white or deep pastel colors using 1.5 to 2.0
fluid oz. of universal colorant per gallon. Dry time depends on the
amount of colorant used. Set to touch 2 hours, 2 to 3 hours
before recoat or topcoat. Tinting may affect the hydrostatic water
pressure resistance.
PRODUCT APPLICATION .
SURFACE PREPARATION
Surfaces must be clean, dry and sound, and free of dirt,
efflorescence, mold, algae, sandy mortar or any material that
could compromise coating adhesion. New concrete must be
cured for at least 7 days prior to coating. Test cast concrete for
the presence of form sealers or release agents by sprinkling with
water. If the surface turns dark with the water, WaterTite LX can
be applied. If not, the surface must be chemically cleaned or
mechanically abraded to remove release agents.
PRODUCT APPLICATION (cont..)
Clean porous surfaces like uncoated concrete block by sweeping
or blowing down with oil-free, compressed air. Wash, vacuum,
scrape, wire brush or mechanically abrade dense concrete
surfaces. If surfaces are pressure washed, allow to dry three
days prior to coating. Remove exterior mildew with Jomax
®
House Cleaner & Mildew Killer or equivalent. Remove
efflorescence with WaterTite Etch
®
or equivalent. Rinse the
surface thoroughly after chemical cleaning. Un-rinsed acid salts
may cause premature coating failure. Surface can be damp but
not glistening with water at time of application. Water-Tite LX can
be applied over previously painted surfaces. However, the
waterproofing ability is dependent upon the integrity and moisture
resistance of the prior coating. For maximum waterproofing
performance, apply WaterTite LX over uncoated surfaces.
Soundness of Surface - Surface of concrete and mortar joints
must be hard and firm - not loose or sandy. The surface is un-
sound if it can be scraped or gouged with a flat screw driver
using moderate pressure. Unsound mortar or deteriorated
concrete should be removed and repaired prior to coating.
Cracks and joints must be sealed with WaterTite Hydraulic (15
minute dry time) and/or WaterTite Polyurethane Sealant (72 hour
cure) or equivalent products. When waterproofing exterior, above
grade walls, parapet walls must be capped and the backside
sealed with a flexible waterproofing membrane.
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
Mix thoroughly to ensure any settled pigment is re-dispersed
before application. DO NOT THIN. Apply only when air, material,
and surfaces temperatures are between 50-90°F (10-32°C) and
the relative humidity is or less than 85%. Apply two or three coats,
depending on the surface and job requirements to form a
continuous pin-hole free coating. Apply the first coat using a high
quality synthetic brush or ¾” nap roller. WaterTite LX can be
spray applied with an airless sprayer or conventional sprayer.
Follow manufacturer’s application instructions. If using a roller,
back brush the 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. The second coat can be rolled or
brushed on. For very porous or rough surfaces, a third coat may
be required if pin-holes are evident.
