Expert Verdict Reviewed by the SuperArbor Pro Desk

Apply SA Primer only to clean, dry substrates and allow it to dry fully before installing self-adhesive membrane, since trapped solvent can affect bond. Use the red color to check for skips and re-prime porous areas as needed. Keep pails sealed between uses and follow temperature restrictions on the data sheet.

Use with adequate ventilation and read the SDS; primer solvents are flammable and require flame-free work practices.

Order the Johns Manville SA Primer 5 gal pail to prepare substrates for reliable self-adhesive membrane bonds.
