3M™ Windo-Weld Ribbon Sealer Kits

The 3M Windo-Weld Ribbon Sealer Kit is intended as a replacement to original equipment butyl installation. It can also be used as a secondary sealant when installing secondary glass with urethane adhesive.

How to apply the 3M Windo-Weld Ribbon Sealer

• Prepare glass by cleaning the glass perimeter with a glass cleaner. Wipe dry with lint-free cloth.
• Remove the glass with the help of the necessary tools.
• Prepare the metal by cleaning it with VOC-compliant 3M Cleaner. This removes contaminants such as grease, grime, oil and more on the surface. Scuff and then prime any bare metal scratches with a primer.
• Apply the 3M Windo-Weld Ribbon Sealer to either the pinchweld or glass. We suggest that you apply the sealer to the pinchweld.
• Start seal from the bottom of side pillar. Line the sealer with the edge of pinchweld with thumb pressure. Do not overlap; instead, butt the ends of the sealer.
• It is important to use the included setting blocks as the 3M Windo-Weld Ribbon Sealer Kits can be tacky and compressible.

Placing Glass

• Place glass on the pinchweld
• Ensure that the glass makes contact with the sealant
• Use hand pressure to provide excellent contact and seal
• Paddle sealant around edge
• Perform the water test
• Use the 3M Cleaner to clean the surface of contaminants such as grease, oil, grime, adhesive and more

Storage
