Why use a primer before using CSP?
A. A primer has two-fold effect: first- it provides a smooth surface on the material to be painted as it fills up porous material like paper/wood, and thus saves on the paint material (since porous material has tendency to absorb paint). Second- it acts as an anchor/bond between the surface of the material and the paint, resulting in better adhesion, giving longer lasting painted surface. We recommend any good acrylic/nitrocellulose (NC) based primer to be applied with brush or spray on the pre-treated surface as explained under A.6.a. Top Q.8 Can CSP be coated on any material surface? A. It depends on several factors. CSP can be coated to the following material surfaces: paper; board; wood (with finished surface); mild-steel (iron); other metals; glass; ABS; ceramic, etc. However, for plastic polymers such as PP and other engineering plastics, we have a special PLASTIC SPRAY PAINT (to be available very shortly). CSP also can not be coated on materials like wax and thermo-cole. We must
