The Product must be stored in original unopened and undamaged packaging in dry conditions and temperatures between +5 °C and +35 °C. Protect the Product from direct weather exposure and sunlight. Store in a vertical position. Pallets may be stacked on top of the rolls if all following conditions are met:

• The rolls have a wooden board on top, separating them from the pallet above.

• The weight of the pallet above is equal to or less than the weight of the rolls.

Always refer to packaging.

The application temperature should be between 4°C to 45°C. Application procedures may vary slightly depending upon site conditions. The general recommended guidelines for the application of the self- adhesive waterproofing system is as follow:

The surfaces shall be cleaned thoroughly of all contaminants like dust, traces of curing compound, oil and grease. All surface imperfections, protrusions, structurally unsound and friable concrete must be removed and repaired. Fill surface irregularities such as blowholes, honeycombs etc., with Sika repair mortar to achieve a smooth and level surface. Repair cracks either by resin injection or by caulking depending on the nature of cracks. Where needed, provide expansion joints and seal them with Sika range of construction sealants (see separate data sheets). Consult Sika representatives for advice on repair methods.

Priming
Use Sika Primer or a similar bituminous primer. Apply the primer by brush or roller over the prepared substrate at a rate of 6 to 8 m²/ L. Lay the membrane after the primer reaches touch dry state. Prime only an area that can be covered within the same working day.

Alignment
Start the installation of all membrane plies from the low point or drains, so that the flow of water is over or parallel the piles, but never against the laps. All overlaps at the membrane seams shall be installed so as to have “up” slope laps over “down” slop laps. Begin membrane application by unrolling the roll of SikaShield® Exx HDPE 1,5 mm membrane and aligning the side laps.

Placing
It is important to lay the membrane without creases. Peel back the release paper to a length of about 30cm and stick the membrane onto the prepared substrate, starting preferably from one end of the areas. Unwind the roll in a straight line, without creasing by pulling the release paper carefully. Using a rubber roller, simultaneously smooth the membrane from the center outwards to the edges for optimum adhesion
and to expel any entrapped air. After one roll has been installed and smoothed, lay the next roll with at least 100mm overlap at the ends and 50mm along the edges. Ensure total bonding at the overlap by using the roller.
