Application Information
Non slip system for use on Waterproofing membranes
Designed for use directly over the Bullet Roof Waterproofing system. The Tread Sure Anti Slip system can also be applied
to EPDM and TPO membranes subject to a site adhesion test being satisfactory. Tread Sure Anti Slip is pre-pigmented
and is applied in one coat.
Recommended Environmental Conditions
Support temperature should be between 10ºC and 30ºC. Support moisture should be less than 4%. Relative humidity of air
should be less than 85%. High moisture conditions can lead to bubble formation under the membrane surface.
Preparation
For use over the Bullet Roof Smooth or Reinforced waterproofing membranes as anti slip protection. Apply one coat of
Metflex Anti Slip Roof Walkway following the relevant application guidelines.
On old / other installations: Clean and prepare the surface to remove all grease and dirt, then roller apply the Tread Sure
Anti Slip. Subject to site adhesion test being satisfactory.

Mixing
Stir gently before use. Use low-speed stirring equipment to minimise air bubble and allow to stand for 5 minutes before
using.
Application
Apply one coat by roller, brush or airless spraying equipment and whilst still wet, lightly hand broadcast the Aluminium Oxide
Anti Slip Aggregate into the wet surface. Allow the coating to cure overnight before trafficking the surface. Although not
strictly necessay, it is highly recommended use all the contents. If not, ensure total sealing of the remainder. Note: Some
roller materials are damaged by the solvent. If in doubt, is recommended to test before use. Excess pressure, along with
high temperature and humidity, may give rise to microbubbles that makes the surface to look hazy. Mix the Tread Sure
Anti Slip by means of a low speed stirrer to re-distribute any settled out pigment and wait some minutes to allow
bubbles to disappear. Apply, as a general rule, at 200-500 g/m2.
Curing Time
Curing time is dependent on the environmental conditions. Curing rate increases with temperature and humidity rises. The
following table gives a rough estimation of the curing time under diverse conditions for a 500 microns coat.

Reapplication
A second coat of Tread Sure Anti Slip can be applied, if desired, when the first one is no longer sticky. Do not
wait more than 24 hours for the next coat application to ensure good intercoat adhesion.
Return to Service
At usual conditions (25ºC, 50% rh) the Tread Sure Anti Slip can be walked on after an overnight cure. Final
hardness development may take up to 15 days in low temperature conditions.
Tool Cleaning
Liquid Tread Sure Anti Slip can be cleaned with solvent, acetone and alcohols. Once hardened, it cannot
be dissolved.
Cleaning and Maintenance
It may be necessary to reapply Tread Sure Anti Slip if they are worn out due to traffic, weather, corrosion, etc. For
stain removal, a surface treatment with solvent or isopropyl alcohol may be attempted. Strong acids are totally
inadequate. Some solvents may damage the membrane. If this happens, the affected area has to be cleaned and repaired
with a new Tread Sure Anti Slip application. Contact Towerflex for details.
Safety
Tread Sure Anti Slip contains isocyanates and flammable solvents. Always follow the instructions provided in the
material safety data sheet and take the precaution described there. As a general rule, a suiable ventilation must be ensured
and all ignition sources must be avoided. This product is intended to be used only for the uses and in the way here
described.
Environmental Precautions
The empty containers must be left open to cure off any residual product for a period of at least 7 days before disposal.
