TREADSTONE® APS Advanced Primer/Sealer

Formulated Materials® APS is a Low VOC acrylic primer and sealer that improves the performance of fire-rated underlayments and self-levelers by providing a solid bond to the substrate during installation and increases moisture and abrasion resistance and durability of underlayments and levelers when applied to fully cured surfaces. APS is easy to use and is appropriate for use with both porous and non-porous substrates when applied as a primer

• Provides a strong, positive bond when pouring underlayments and levelers over wood, concrete, metal, gypsum, and most properly prepared substrates
• Improves surface hardness and reduces porosity and moisture absorption of cured underlayments and levelers
• Low VOC Formula is non-reactive and non-toxic
• Low-odor formula is tinted blue to provide visual indicator for proper application
• Approved for use with all Treadstone® and HydroPhase™ underlayments and levelers
