The product must be stored properly in undamaged, original, sealed packaging in dry and cool conditions, protected from direct sunlight at temperature between +5 °C and +25 °C.

1.1 mm approx.

-20 °C to +80 °C

+5 °C min. / +45 °C max.

+5 °C min. / +45 °C max. Min. 3 °C above dew point temperature

The substrate must be stable, clean, dry and free of all contaminants such as dirt, oil, grease, cement laitance, old sealants and poorly bonded paint coatings which could affect adhesion of the adhesive / sealant. The substrate must be of sufficient strength to manage with the stresses induced by the tape during movement.

Prepare the substrate by removal techniques such as wire brushing, grinding, sanding or other suitable mechanical tools. All dust, loose and friable material must be completely removed from all surfaces before application of any activators, primers or tapes. Sika® MultiSeal AP generally has strong adhesion without primers/activators to most dry, clean and sound substrates. For optimum adhesion, the following procedure shall be followed:

Non porous substrates:
Metals, plastics, coated surfaces and glazed tiles have to be cleaned and pre-treated with Sika® Aktivator-205 by using a clean towel. Before sealing allow a flash-off time > 15 min (max. 6 hours).

Porous substrates:
Concrete, aerated concrete and cementitious plasters, mortars, brick, etc. have to be primed with a bituminous primer (e.g. SikaShield® Primer) by using a brush. Before applying Sika® MultiSeal AP allow a flash-off time > 1 hour.

Important:

The adhesion performance can be improved by heating up the Sika® MultiSeal AP tape during application.

Important:

Do not use Sika® MultiSeal AP on natural stone.

Important:

Do not overpaint the tape with solvent-based paints.

Important:

Direct contact with joint sealants and adhesive must be avoided or compatibility must be tested prior to application.

Important:

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

Important:

Do not use Sika® MultiSeal AP for joints under water pressure or for permanent water immersion.

Important:

Not suitable for overhead application when service temperatures are > +25 °C.

1. Cut the tape to the required length.
2. Remove the release film and press the tape firmly onto the substrate with a suitable roller.

Note: For overlapping, ≥ 5 cm is required. The upper side of Sika® MultiSeal AP can be over-painted with most conventional paint systems.
