Add the adhesive powder into cool water, stirring it continuously. Let the mixture settle for 5-15 min. and stir once more. A higher temperature shortens the adhesive's pot life. The adhesive is recommended to be applied with a roll applicator machine. When using a manual roll applicator the adhesive must be applied as an even layer onto the whole surface. After pressing the boards need not be cooled, but the following work phases can be carried out immediately after the pressing.
