Consumption
600 ml will be enough for approx 15 m joint, based on width of 4 mm and 10 mm depth.
Cleaning:
Tools should be cleaned with acetone before the sealant has completely cured. After curing, abrasion is necessary.
Packaging and storage
600 ml sausages, 20 pcs per box and 720 pcs per pallet. 12 months in the original, hermetically sealed cartridges in +5 - 25 °C.
Laying instruction
1. The surface must be clean, dry, free of dust, oil, grease and any contaminants that could harm bonding. If the substrates need to be cleaned use acetone.
2. Apply Linoprimer for better bounding.
3. Linoflex® 40 can be applied with a manual or pneumatic gun.
4. After application, use a putty knife with soapy water to smooth the joint.
5. Linoflex® 40 should be used within 24 hours of opening the cartridge protection. (otherwise, the sealant could harden in the cartridge).
6. Do not apply at a temperature under + 5 °C. In cold weather, store the Linoflex® at 20 °C before use.
7. Avoid any contact with non-cured Linoflex®.
