TOPFLEX Flexible, polymer cement waterproofing slurry

                                                Flexible, polymer cement waterproofing slurry

DESCRIPTION
Topflex is a two part, prepacked system,
consisting of a liquid polymer as Part A and a
premixed powder as Part B. The two parts on
mixing yield a brushable, smooth slurry with
excellent bond to most substrates. The product is
based on selected synthetic resins and cements.
Topflex is in compliance with Bureau
Veritas Potability test for used in drinking water
reservoirs or tanks.

RECOMMENDED USES
Topflex is designed to be used as an
effective waterproofing membrane on a variety of
substrates. Applications include:
 Waterproof coatings to the internal faces of
water tanks, sumps, reservoirs, planter boxes
etc., before tiling or other surface finishing;
 Treating terraces, balconies, kitchen & toilet
floors as a sandwich treatment, to prevent
water ingress.
 Treating bridge & flyover decks before wearing
course to protect concrete from rainwater
ingress.
FEATURES AND BENEFITS
 Polymer modified - Improved bond strength on a
variety of substrates.
 Permeable to water vapours - Allows surface to
breath, preventing buildup of moisture in
structure, reducing maintenance.
 Flexible - Can withstand moderate movement of
hairline cracks. Bridges cracks up to 0.3mm in
width, reducing maintenance.
 Weather resistant - Suitable for use in exposed
conditions.
 Brushable consistency - Easily applied by brush
or spray.
 Non-toxic – Can be applied onto surfaces in
contact with drinking water.

APPLICATION
Surface Preparation
Correct substrate preparation is critical for
optimum performance. Surfaces should be
structurally sound direct tensile strength of more
than 1.5MPa via a pull off tester with a load rate of
100N/s), clean, and free from laitance, loose
particles, oil and grease, old coatings, curing
compounds or any other contaminants.
Remove oil or grease and wax contaminants by
scrubbing with industrial grade detergent or
degreasing compounds before mechanical
preparation. Cement laitance, loose particles, mold
release agents, curing membranes and other
contaminants must be removed from the surface by
shot-blasting, grinding or scarifying followed by
vacuum cleaning.

STATEMENT OF
RESPONSIBILITY
The technical information and application advice given in thisVMIX Construction Chemicals publication are based
on the present state of our best scientific and practical knowledge. As the information herein is of a general
nature, no assumption can be made as to a product's suitability for a particular use or application and no warranty
as to its accuracy, reliability or completeness either expressed or implied is given other than those required by law.
The user is responsible for checking the suitability of products for their intended use.
NOTE
Field service where provided does not constitute supervisory responsibility. Suggestions made by VMIX either
orally or in writing may be followed, modified or rejected by the owner, engineer or contractor since they, and not
VMIXConstruction Chemicals, are responsible for carrying out procedures appropriate to a specific application.

Mixing
Mechanical mixing is necessary. A slow speed
(300 rpm), heavy duty electric drill with a wing
type paddle is recommended. Place approx. 75%
of Part A of the pack in a clean pail. Keeping the
mixer running, add the Part B slowly. Mix for at
least 3 minutes to get a lump-free homogenous
mix. While continuing to mix, add all of the
remainder of Part A if applying on a horizontal
surface, or a part of it if applying on vertical
surfaces till the required consistency is obtained.
Allow to stand for 2-3 minutes and remix before
application.
Placing
It is extremely important that the area being
treated is shaded from direct sun and wind to
prevent rapid drying of the coating.
CURING
Topflex must be protected against rapid
drying due to direct sun exposure, high
temperatures or wind. Curing by wet burlap,
polyethylene sheet
CLEANING
Clean tools using water and rags before the
resin system hardens. Hardened material can
only be removed mechanically.
ESTIMATING DATA
The recommended coverage of Topflex is
1 kg/m² per coat to obtain an approximate wet film
thickness of 0.8 mm (± 0.08mm).
Actual coverage depends upon the method of
application, the texture and porosity of the surface.
Therefore material requirement is approximately 2
kg/m² for a total dry film thickness of 1 mm
(± 0.1mm) in two coatings.
Note: use only complete pack.
PACKAGING
Topflex is available in 18kg packs
component  A (6kg polymer)
component  B (12kg powder)
SHELF LIFE
Topflex can be kept for12 months in
original unopened packing when stored indoors.
Do not store in direct sunlight and avoid allowing
the material to freeze which will render the material
unusable.
PRECAUTIONS
For detailed Environmental, Health and Safety
information, please consult and follow all
instructions on the product Material Safety Data
Sheet. Contact your local VMIX office for the
latest version.
