  • Excellent adhesion to properly prepared concrete
  • Abrasion resistant
  • Good chemical resistance
  • Minimizes dusting, staining, and dirt penetration


  • Contains solvent; do not use without adequate ventilation
  • Do not use below 50°F
  • Substrate must be structurally sound, clean and free from curing compounds and other contaminants

Product #671 Conductive Epoxy Primer Sealer produces the best results when applied with a medium napped shed resistant roller. It may also be applied with brush, squeegee, and conventional or airless sprayer. Spread Product #671 Conductive Epoxy Primer Sealer at a rate of 200 sf per gallon to yield approximately 4 dry mils. Check conductivity of the area prior to recoating. If Product #671 Conductive Epoxy Primer Sealer is being used alone as a sealer the recommended dry film thickness of 8-10 mils (2 coats @ 200 sf per gallon). Roughen the surface if allowed to cure more than 24 hours between coats. Be sure to verify conductivity after completing installation.

Do not apply to surfaces below 50° F or above 120° F. Do not apply over damp or wet surfaces.


Clean up immediately with Xylene solvent. Remove from skin while still wet, wash with soap and water. Consult MSDS for safety and health precautions.
