The MultiSeal by Sika is an outstanding product that's perfect for completing various remedial work on the exterior of a building. Sika's scientists formulated this product with a high-strength self-adhesive tape, perfect for application onto most building substrates. It's created with a laminated metal film in aluminium and reinforced by a polyester film on the upper side, all of which are suitable for paints to be applied onto. Applications this product has been used on include;

Facades
Broken roof tiles
Leaking roof gutters
Chimneys and roof lights
Trailers and Caravans
Office containers
Roofs, including sheet metal work
Various types of ductwork

Preparation

Preparation is essential; if not completed correctly, it can cause further problems in the future. Ensure the surface on which you intend to apply this is stable, clean, dry, and free from contaminants such as dirt, grease, oil, etc. Also, note that this product creates stress during movement, so ensure it's applied appropriately. You can enhance the adhesion of this product using the appropriate primer/propriety to clean the surface before application.

Application

Cut the tape to the required length and release the film.
Place it into place, pressing firmly, using a hard-wheeled roller or another suitable tool to ensure no air is trapped.
You can enhance adhesion further by heating it whilst it's on the surface.
Any overlaps must be at least ≥ 50 mm.

Limitations and Notes

This product is suitable for painting systems except for solvent-based paints.
Do not use this product on natural stone.
This product can cause discolouration on the tape, coatings, plastic or natural stone.
Water can infiltrate underneath on porous surfaces if not applied correctly, causing adhesion issues.
Direct contact with joint sealants and adhesives must be avoided, or a preliminary test must be done to check for compatibility.
Joints under pressure or water immersion applications are not suitable for this product.
