Brushing Reducer for Epoxy Primers and Urethane Topcoats Use T0031 in Awlgrip Topcoats, 545 Epoxy Primer, and Awlquik Sanding Surfacer in brush/roller applications. T0031 evaporates very slowly, keeping the paint film open, maximizing flow and levelling while minimizing brush marks and roller stipple. For Awlgrip Topcoats, add T0031 at 10—33% of the total volume of the mixed color base and converter. Application and cure temperatures between 60—90° F (16—32° C) produce the best results, with 70—85° F (21—29°C) being the optimum. T0031 is not recommended for use in spray applications. If a "retarder" reducer is needed for spray application, T0005 should be used. VOC: 940 g/lt or 7.8 lbs/gallon
