Instructions. New wood. Sand with 150-180 grit sandpaper and clean the surface from dust and grease by means of acetone, because these substances could avoid the adhesion of the coating. If the object is exposed outdoors, it is recommended to treat it previously with a coat of Gel Wood Stain RGxx80. Coated wood. Sand the support with 180-240 grit sandpaper. If some coating films peeled off, make sure to remove them completely. Clean the surface from dust and grease by means of acetone, then apply Decogrip Solution RE20xx in more than two coats. Metal. To decorate rusty metal surfaces, remove the rust with brush or sandpaper before the application of Decogrip Solution RE20xx. Plastic. Given the huge variety of available substrates, it is previously necessary to evaluate the adhesion over the support. Before the application, clean the surface from dust and grease by means of acetone. To increase the adhesion, it is possible to sand slightly the support with 180-240 grit sandpaper. Glass and ceramic. After evaluation of substrate adhesion, add 2-4% of RY0406 Adhesion Promoter. Clean the substrate with RR1050, then proceed to coating.
