Prepare surfaces for reliable RF shielding paint application with YSHIELD® GK5 Primer Concentrate. Specially formulated for use with CPC and YSHIELD® RF shielding paints and other carbon-based coatings, GK5 helps consolidate and prepare old paint, brittle or chalky surfaces, and highly absorbent substrates.

Its deep-penetrating formula strengthens the substrate, improves adhesion, and regulates surface absorbency, creating a more consistent base for the shielding coating. GK5 is particularly useful for preparing problematic mineral and absorbent surfaces prior to applying shielding paints such as CPC-54 RF Shielding Paint.
