Instructions for use

The surfaces to be bonded must be free from dirt and dust. Apply the adhesive in an even layer on one of the surfaces. Press the surfaces together within the open time and keep them firmly pressed until the glue has bonded. Remove fresh glue stains with a dry piece of cloth and clean the residue with acetone or xylene. Hardened glue can only be removed by mechanical means. Temperature of room, materials and glue +18–20 °C. Use Kiilto D4 in normal room temperature. Both the materials and adhesive should be allowed to acclimatise to the room temperature. Prevailing conditions such as temperature of the room, glue and materials as well as air humidity, quality and moisture of materials and the amount of glue applied strongly affect the bonding speed and curing. Therefore, our recommendations should only be used as a guide.
