For all usual applicator systems. Reactive PVAc dispersions may undergo an
increase in viscosity during the storage period, due to their components.
Higher temperatures contribute to this increase in viscosity. The product
should therefore be stirred before use.
Avoid contact with iron, tanniferous wood may discolour.
