LX Ultra 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 above
or below grade 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 Ultra meets
ASTM D-7088 Resistance to Hydrostatic Pressure and
ASTM D-6904 Resistance to Wind Driven Rain.

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 Ultra can be applied. If not, the surface must
be chemically cleaned or mechanically abraded to remove
release agents.
PRODUCT APPLICATION (cont.)
SURFACE PREPARATION (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. WaterTite LX Ultra 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 Ultra over uncoated
surfaces.
Soundness of Surface - Surface of concrete and mortar
joints must be hard and firm - not loose or sandy. The
surface is unsound 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 Cement (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.
