PRODUCT APPLICATION (cont.)
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 Ultra 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.
COLOR/TINTING
WaterTite LX Ultra Mold & Mildew-Proof Waterproofing Paint
produces a smooth, bright white finish. It can also be tinted
to other off-white and pastel tones. Maximum amount of tint
should not exceed 2 ounces of universal colorant per gallon.
Mix on a mechanical shaker for 7-9 minutes or use a drill
motor. Multiple containers of tinted paint should be boxed
(intermixed) to ensure color uniformity.

DRY AND RECOAT
Dry and recoat times are based on 70°F and 50% relative
humidity. Lower temperatures and higher humidity will
increase dry time. Dries to the touch in 2 hours. Allow the
first coat to dry a minimum of 2 hours before applying the
second coat. After the second coat has dried, inspect the
surface for pinholes. Reapply additional paint to those areas
as necessary. Protect from rain for 8 hours after application.
LIMITATIONS
WaterTite LX Ultra is not an elastomeric and will not expand
and contract with movement in the substrate. It will not
provide protection against moisture penetration through
cracks in mortar, expansion joints or junctures between
dissimilar materials. WaterTite LX Ultra will not penetrate
and fill inaccessible surfaces, unopened bug-holes, raked
mortar joints, etc. Do not use on glazed or non-porous
surfaces.
CLEAN UP
Clean hands and tools with soapy water. Drips and runs
should be removed immediately. Once dry, drips and runs
can be removed by sanding or stripping.
