APPLICATION PROCEDURE
Ensure substrate is clean, dry and free from oil, grease,
sealers, curing compounds, paints, polymer coatings,
dust or any other contaminant or coating that may
affect the bonding of Bostik Ultralevel HD onto the
substrate. All foreign material, e.g. bitumen, adhesive or
latience must be removed by mechanical means such
as scabbling, capture shot blasting or grinding. The
substrate must be primed prior to the application of
Bostik Ultralevel HD.
MIXING
Bostik Ultralevel HD requires 4.3 litres of clean water
per 20 kg bag & is best mixed with a forced action, high
shear stirrer, powered by a heavy duty electric mixing
drill at approx. 600 r.p.m. Add Bostik Ultralevel HD to
pre-measured water in a clean mixing bucket,
whilstcontinuously mixing the contents. When the
entire contents of the bag have been added to the
water, mix for a further 2 minutes to produce a smooth
homogenous consistency. DO NOT MIX BY HAND. DO
NOT ADD EXCESS WATER. Discard any Bostik Ultralevel
HD that has hardened or stiffened in the mixing bucket.
APPLICATION
Pour the fully mixed Bostik Ultralevel HD onto the
primed substrate and allow material to seek its own
level. It may be spread with a steel trowel, spreader or
squeegee. Keep the trowel slightly inclined to obtain
desired thickness of cover. To ensure uniform
consistency & continuous flow, it is advised that
subsequent mixes are ready to enable continuous
pouring until the entire area to be levelled is complete.
Minimum thickness 6 mm. Protect the finished areas
from damage until Bostik Ultralevel HD has dried.
COVERAGE
A 20 Kg bag of Bostik Ultralevel HD mixed with 4.3 litres
of clean water will yield approximately 13 litres. This
quantitywill cover approx. 2.2 m2 @ 6mm thickness.
