Ultra Level
™
UL-221
Self-leveling Modied Mortar Underlayment
Description
LANCO® Ultra Level™ is a
polymer modified cement mortar
base underlayment requiring only
water to form a free flowing liquid
mortar that seeks its’ own level,
thus producing a smooth, hard, flat
surface free of cracks and
imperfections. It is designed to
eliminate areas that accumulate
water and will correct
imperfections, seal cracks, smooth
rough surfaces and cause rain
water to flow in a desired direction.
Ultra Level™ does not require
trowelling for finishing, thus
reducing time and labor.
This product was developed for
use in leveling roofs and floors and
will level surfaces up to 1 ½” thick.
Product Advantages
• Interior and exterior use
• Modified polymers only require
adding water
• Used over a wide variety of
substrates.
• Pours 1/8” to 1 ½” in thickness
Product Uses
For industrial, commercial and
residential application on new or
previously coated concrete, wood,
bonded tar & gravel, built-up
asphalt roofs, modified bitumen
(smooth & granulated), single ply,
EPDM, TPO. Should be approved
roof systems and/or substrates and
should be in sound solid condition.
Application & Coverage
Mixing: Always mix thoroughly
before application. Mix the 40 lbs.
bag of powder with 6 ¼ quarts of
clean water. Add the powder to the
water slowly while mixing with a
heavy-duty electric drill (½”) affixed
with mixing paddle at 650 rpm.
Mix thoroughly for 2 to 3 minutes
until a lump free consistency is
obtained.
Ultra Level™ UL-221 will cover
approximately 40 sq. ft. per 40 lb.
bag at a 1/8” (3mm) thickness or
20 sq. ft. per 40 lbs. bag at ¼”
thickness. Apply or pour the
prepared product over surface and
it will find its’ own level within 20
minutes. If a second layer is
required, install immediately after
the first layer is dry and hard
enough to walk over. Allow primer
to dry to a tacky state before
applying a
second coat of Ultra
Level™ UL-221.
When multiple applications are
required to achieve a thickness
greater than 2” a structural
engineer should be consulted.
Cleanup: Clean all equipment
immediately after use with warm
soapy water. Completely flush all
spray equipment with this solution.
