Check the compatibility of the solvent used with the substrates. If necessary, rub down metal surfaces beforehand. Clean them after rubbing down. Allow the substrates to dry after degreasing. If necessary, apply a primer.Not: when using solvents, extinguish all sources of ignition and carefully follow the safety and handling instructions given by the manufacturer or supplier. We recommend to clean concrete with a metal brush.Caulking:
