5. Can you apply topcoat paint to drywall without previous priming?

If the base to be painted has not been covered with anything you should apply correct primer before applying the topcoat paint. It equalizes absorptiveness of the base, improves the adherence of topcoat paints and enables even drying of new drywalls. The product does not require diluting. It should be mixed thoroughly before applying. Can be applied with brush, roller or by spraying. Topcoat paint can be applied to the base prepared in that way.
