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.
Instruction
Ensure that the surfaces to be sealed are clean, dry and free from grease.
A preliminary compatibility test is recommended.
The application temperature must be between + 5℃ and +40℃.
Dimensions of the joint:
Minimum width X Minimum depth: 5mm X 5 mm
Recommendation: width = 2 x depth
The joint must be smoothed with spatula within 5 minutes of application to ensure good contact between the sealant and the substrate.
The adhesive tape must be used where precise lines of joints or clean lines are required. Remove the tape immediately after applying the product.
An excess of sealant can be removed from tools and surfaces before it cures, using solvent. Once hardened, the material can be removed mechanically
Storage and shelf life
1.They should be protected from water, frost and adverse air conditions.
2.They should be kept dry and cool on wooden pallets at between +5 degree C and +25 degree C in moisture free conditions.
3.The opened products should be consumed immediately.
4.Shelf life is maximum 12 months conditional to complying with the aforementioned storage conditions.
