DESCO INDUSTRIES INC TECHNICAL BULLETIN TB-7001 Statguard® Conductive Acrylic Paint Made in the Application Instructions United States of America Allow newly applied paint to dry a minimum of 48 hours before proceeding with the test. At humidity levels over PMS 432 55% RH, allow 72 hours of drying time before testing. Use a razor to cut a cross or a few perpendicular lines over a 3” by 3” (75 mm by 75 mm) area on several spots of the thoroughly dried area. (See Figure 2). Use a piece of masking tape to cover the marked area. Make sure the tape is thoroughly adhered to the test PMS 429 area. Pull the tape off the surface and examine the amount of paint which has peeled off during the test. If any significant portion is transferred to the tape, better surface preparation (acid etching, cleaning or sanding) should be done on the substrate to enhance the adhesion. If your test patch is on a bare or prepped concrete we recommend Bulls Eye® Water-Base Primer and Sealer Figure 1.
