SNABBS Cementitious self-levelling screed
DESCRIPTION
TM SNABBS
is a pumpable, self-levelling, self-smoothing and quick setting
screed for new and old concrete floors. It is a polymer modified
cement base screed with very good properties such as low shrinkage
and high adhesion strength for pedestrian traffic.
Suitable for interior or exterior use as an underlayment or overlayment.
It's high strength and excellent durability can be further enhanced
by further enhanced by adding FLEXTILE
43 LATEX
additive.
USES
Smoothing
and levelling of surface irregularities where perfectly even floor
surfaces are require for the subsequent installation of PVC flooring,
carpets, parquets, ceramic tiles, marble, natural stone or simply
as an overlayment. Due to its fast and easy application. TM SNABBS
is especially suited for used on large project such as hospitals,
department store, school and administrative buildings, showrooms,
military barracks, corridors, void desks and any other areas which
need levelling and repair.
FEATURES
BENEFIT
* Fluid consistance ensure product levels to a smooth even
surface
* Minimum shrinkage to cracking and spalling
* Hogh early strength
* Quick setting
* Excellent bond strength to concrete substrates
* Can be laid in thickness of 1 - 30 mm
* Contains synthetic fibres
* Fast and easy installation resulting in reduce labour costs
* Can be mixed with FLEXTILE
43
latex Additive for even higher
strength and abrasion resistance

PREPARATION
The
substrate must be well prepared before application. All hollow substrates
must be properly repaired. Clean surface so that it is completely
free from laitance, oil, war, paint or other contaminants which
will prevent good bonding. Grind concrete surface when necessary
to provide suitable blonding surface. Shot blasting may be necessary
to roughen to receive screed. Surface must be dry before applying
TM
PRIMER 001.
PRIMING
Priming
coat to be TM
PRIMER 001
diluted with water 1:1 and applied with a soft broom at a rate of
0.15 - 0.20 litre/m2. If the floor is very dry, two treatments are
needed. Allow primed surface to dry before laying screed.
YIELD
One
25kg bags TM SNABBS when mixed with 5.0-5.5 litre water will yield
approximately 15.0-16.5 litres mix.
MIXING
AND APPLICATION
TM
SNABBS
can be mixed by hand with a slow speed drill attached to a mixing
propeller. For large jobs, use of mixer pump is preferable. ADD
5.0-5.5kg of water per bag TM
SNABBS,
mix for minimum 2 minutes to produce a smooth, homogeneous mixture.
Pour/pump the mixture onto the primed substrate, start from one
corner and place in a continuous stream along one edge of the substrate,
then return back to lap the first placement stream to the required
thickness. Use notched trowel for fine adjustment of level. Rollthe
surface with spiked roller to release any trapped air in the screed
if necessary. Allow the screed to be cured and hardened before open
to foot traffic.
GENERAL
As
with self-levelling screeds, protection from rain or strong U.V
rays is advisable before setting.
