This will achieve a dry film thickness (DFT) of 1 mil (15-25 microns). Maximumrecommended film thickness during a spray application is 1 coat totaling 2 mils (80microns) WFT, or 1 mil (25 microns) DFT. A cross coat application will insure a moreuniform finish.To achieve optimum performance and adhesion ALEXSEAL ® Suede Coating 702 shouldalways be applied over the suitably colored ALEXSEAL ® Suede Primer 701 (see colorcard or price list for appropriate primer color selection).118ALEXSEAL ® Professional Application Guide version 0.4.3ALEXSEAL.COM > Europe: +49 0 40 75 10 30 > North America: +1 843 654 7755119
