For best results, we suggest preparing the surface using 240-320 grit stearate abrasives as they provide a higher efficiency than conventional. Ensure the surface is completely clean of dust and debris before coating.
With good drying conditions and air circulation (20°C), a good build can be achieved with two coats of 200 g/m² with an interval of 50 minutes in between. Under these circumstances, the substrate can be sanded after 8 hours. Lower temperatures and higher relative humidity can lead to longer drying times, but it is possible to speed up drying using heated ovens.
Sayerlack TU0574/13 White PU Primer can be over coated with any pigmented PU Topcoats such as Sayerlack TZ99**/XX.
Sayerlack TH0793/00 @ 40% for faster drying with good elasticity.
