Restrictions:
● Not suitable for freezing or damp, silicone oil-containing base surface and silicone rubber.
● The surface of the substrate to be adhered must be clean and dry, free of dust, oil and water stains. Adhesive substrate should be used for cleaning with cleaning agent. Otherwise, it may cause bonding failure.
● Temperature and humidity have a great impact on the surface for drying and curing of the sealant, and the construction environment is recommended Temperature 5～35℃, humidity 50～70%RH.
● The node part can be modified and smoothed with a scraper or rigid foam strip, and the ground is partially modified.It can be smoothed with soapy water.
● For construction methods, please refer to the construction instructions or consult our technicians.
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
● Surface must be dry, clean and free from dirt oils, stains or other surface contaminants. Remove all loose materials.
● Always use a standard caulking gun to dispense the sealant.
● Caution: The use of a caulking gun is critical and highly recommended to ensure best finish and faster application.
● Ensure that sealant is in contact with both sides of joints and gaps. Use foam backer rods as necessary.
● Remove excess sealant and smooth it off with a flat knife. Applied sealant is touch dry after 30 mins. Protect from water exposure for at least 4 hours after application. Can be painted over after 2 hours.
