Sika® MultiSeal

Bituminous tape laminated with polyester reinforced film made of aluminium

24 months from date of production

The Product must be stored in original, unopened and undamaged sealed packaging in dry conditions at temperatures between +5 °C and +25 °C. Always refer to the packaging.

Refer to the current Safety Data Sheet for information on safe handling and storage.

IMPORTANT

Discolouration of natural stone substrates, coatings and plastics

Due to the chemical content of the tape, coatings, plastics and natural stones may discolour.

1. Do not use on natural stone substrates.
2. Test plastic or coated substrates for compatibility prior to use.

Substrates must be clean, dry and free of contaminants such as dirt, oil, grease, coatings, laitance, surface treatments and loose friable material.

The substrate must be of sufficient strength to cope with the stresses induced by the tape during movement.

1. Prepare substrate mechanically using suitable abrading, grinding, rotating wire brush or other similar equipment.
2. Completely remove all dust, dirt, loose and friable material from all surfaces with a brush or vacuum cleaner.

The Product has good overall adhesion without primers or activators to most dry, clean and sound substrates. For optimal results, follow the corresponding procedure.

NON-POROUS SUBSTRATES

1. Clean and pre-treat the substrate with Sika® Aktivator-205 applied with a clean towel.
2. Allow a flash-off time less than 15 minutes but no more than 6 hours before applying the tape.

IMPORTANT

Reduced adhesion due to damp substrates

On porous substrates, water infiltration underneath the tape is possible which may affect adhesion.

1. Thoroughly dry out substrates before applying the Product.

IMPORTANT

Reduced adhesion due to overhead application at temperature > +25 °C

When the tape is applied overhead in warm temperatures, the tape's adhesion may be reduced.

1. Do not use for overhead applications when the service temperature is > +25 °C.

IMPORTANT

Reduced adhesion due to water immersion or pressure

1. Do not use for applications permanently immersed in water or under water pressure.

IMPORTANT

Reduced adhesion, surface discolouration, or surface tackiness due to plasticiser migration

Plasticiser migration from the Product may result in reduced adhesion, surface discolouration, or surface tackiness.

1. Test the compatibility of the Product with the substrate before undertaking the project.

Application at low temperatures

Note: Low temperatures can reduce adhesion during application.

1. Warm the tape by handling it for a few minutes prior to application
2. Warm the substrate prior to application using a warm air blower.

1. Cut the tape to the required length. Note Overlaps between cuts must be ≥ 50 mm.
2. Remove the release film and press the tape firmly onto the substrate with a hard-wheeled roller or suitable tool.

OVERPAINTING THE TAPE

The top film side of the Product can be repainted using most conventional water-based paint coating systems.

IMPORTANT Do not use solvent-based paints. Test the paint system with the Product before undertaking the project.

Clean all tools and application equipment immediately after use with petroleum or turpentine. Once cured, hardened material can only be removed mechanically.

For cleaning skin use Sika® Cleaning Wipes-100 and wash with water and soap.
