DESCRIPTION
Ultralevel SL is a rapid hardening self-levelling, single
component cementitious underlay, formulated to
achieve a smooth flat surface with ease of application
and maximum flowwithout any shrinkage or cracking.
RECOMMENDED USES
Underlayment for floor coverings such as carpet,
ceramic tiles, vinyl, parquetry etc. Fast repairs of
uneven concrete floors. residential, commercial &
medium industrial application, from 2 mm to 120 mm in
a single application. New construction & refurbishment
projects, flat smooth surfaces over existing concrete
slabs. Levelling existing uneven concrete floors.
FEATURES & BENEFITS
Accepts foot traffic in 2 hrs. Reinstating large areas in
short time periods. Fast application. Dimensionally
stable. Single component product, just add water.
Installation can be carried out in a single application.
Rapid curing. Can be applied directly onto prepared
concrete surfaces. Eliminates need for sand & cement
screeds. Floor covering may be applied next day.
APPLICATION PROCEDURE
Ensure the concrete substrate is clean & free from oil,
grease, sealers, curing compounds, paints, polymer
coatings, dust or other foreign matter. Excess bitumen,
adhesive or laitance should be removed by light
scabbling or mechanical captive shot blasting or
grinding, followed by vacuuming to remove debris &
dust. Large cracks or holes may be filled using Ultra
Rapidset in accordance with Technical Data Sheet. Prior
to carrying out application, the substrate must be
primed - Porous Substrate must be primed with
Ultralevel Primer, Non Porous must be primed with
Ultra NP primer. New concrete floors must be at least
14 days old priorto application of Ultralevel SL.
MIXING
Ultralevel SL requires 4.3 litres ofwater per 20 kg bag & is
mixed with a forced action, high shear stirrer, powered
by a heavy duty electric mixing drill @ approx. 600 r.p.m.
Gradually add Ultralevel SL to pre measured water in a
clean mixing bucket, continuously mixing the contents.
When the entire contents have been added, mix for a
further two minutes to produce a smooth homogenous
consistency. Do not mix by hand. Do not add excess
water. Discard any Ultralevel SL that has hardened or
stiffened in the mixing bucket. Further addition of water
will not reconstitute a useable mixture.
PLACING
Pour the mixed material on the primed substrate &
allow material to seek its own level. Spread Ultralevel
SL with a steel trowel, spreader or squeegee. Keep the
trowel slightly inclined to obtain desired thickness. To
ensure uniform consistency & application, keep
subsequent mixes ready to enable continuous pouring
COVERAGE : 20kg bag of Ultralevel SL mixed with 4.3
liters of clean water will yield approximately 13 liters.
This quantity will cover approx 1.3 m2 @ 10 mm
thickness.
