Limitations
It must not be used in totally confined spaces where sealant cannot cure due to lack of atmospheric moisture.
Multi-Seal can be applied to a variety of substrates directly. If not sure, we recommend a preliminary compatibility test.
Surface Preparation
● Following cleaning procedure and materials are recommended:
● Glass Degrease with alcohol or MEK
● Aluminium, light alloys and stainless steel Degrease with alcohol or MEK
● Other Metals Lightly abrade then degrease as above
● Wood Lightly abrade surface then remove dust
● Plastics Degrease using an agent recommended by plastics manufacturer
● Concrete and other alkaline Surfaces Brush and remove dust
Instruction
7.The opened packages should be consumed as quickly as possible.
8.The contaminated areas and used tools should be cleaned with white spirit or alcohol. It is cleaned only mechanically after cured.
9.Joint width/depth ratio should be 2:1.
