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 the packaging.

SYSTEM DESIGN

When designing the waterproofing system, make sure that the supporting structure has sufficient structural strength to support all new and existing layers of the system build-up.

SUBSTRATE CONDITION

The substrate surface must be uniform, firm, smooth and free of any sharp protrusion or burrs, clean, dry, free of grease, laitance, oil, dust and loosely adhering particles.

Mineral substrates must be pre-primed with a suitable Sika® primer from the Sika® Igolflex®, SikaShield® or SikaProof® ranges. The Sika® primer selection is made according to the application type and temperature conditions before laying the waterproofing membrane.

1. Repair and fill blow holes and voids using appropriate products from the SikaTop®, Sika MonoTop®, Sikafloor®, Sikadur® and Sikagard® range of materials.
2. Apply the appropriate Sika® primer at the required consumption onto the prepared dry surface. Refer to the individual Product Data Sheet for further infromation.
3. IMPORTANT The primed surface must have no moisture or other contaminants that could influence the membrane adhesion. Allow the primer to dry before membrane installation.

For information on substrate preparation and application, contact Sika Technical Services.

IMPORTANT

Unrolling at low temperatures

At low temperatures, the membrane becomes less flexible.

1. Be careful when unrolling to avoid damaging the membrane.

IMPORTANT

Damage through footwear

Footwear with spikes or sharp protrusions may puncture the membrane.

1. Use footwear with a flat profile when walking over the membrane.

IMPORTANT

Application at less than +5 °C

When applying the membranes at temperatures lower than +5 °C, use heating equipment to ensure that the substrate temperature is within the given temperature range.

IMPORTANT

Application in humid or wet conditions

When applying the membranes in wet or humid conditions, use heating equipment to ensure that the substrate is dry before application.

Seasonal symbol

Note: If a seasonal symbol is printed on the roll’s label, it is advisable to use the membrane during the indicated season.

Tackiness at high temperatures

Note: When laying the membrane at high temperatures, the integral adhesive will become 'tacky' and may restrict laying operations.

ALIGNMENT

IMPORTANT

Avoid coinciding joints

To avoid coinciding joints, lay the membranes parallel to one another. When applying on another bituminous membrane, make sure to straddle the overlaps of the previous layer.

1. Unroll the membrane.
2. Align the membrane.
3. Re-roll the membrane before application.

MEMBRANE OVERLAPS

1. Overlap the membranes by a minimum of 100 mm on the sides and 150 mm on each end or as specified by the supplier.
2. At the end overlap, cut off a corner measuring 100 mm per side at an angle of 45°.

SELF-ADHESIVE BONDING

1. At one end of the sheet, peel away part of the release liner from the underside and bond this end to the substrate.
2. Continue to peel away the release liner sideways from the rest of the sheet membrane and bond it to the substrate.
3. Roll the entire surface area of the applied membrane with a heavy roller to ensure any air bubbles are removed.

Suitable substrates

• Concrete

• Wood

• Metal

• Bituminous membranes with a smooth surface
