Store in a cool and dry place under normal temperature, storage period is 12 months.
The construction surface should be clean and dry. Cover the adjacent surfaces of the glueing with striped rubber paper. Stab aluminum film, cut the tip into 45 degrees, glueing evenly. Use a scraper or latex glove to smooth the glue. Tear off the striped tape before the glue curing. If glue is not used up, natural seal by extruding 1cm rubber wire, and remove the solidified part before next use .
