The PowerChem PrimeMate is a versatile, high-strength bonding agent designed for trade professionals and DIY enthusiasts looking to prepare challenging substrates like concrete, plywood, and tile for subsequent finishes. It serves as an excellent foundation for underfloor heating systems and wet areas, offering superior adhesion and moisture-blocking properties; however, users must ensure surfaces are structurally sound and completely free of dust or debris before application for optimal results.

High humidity or low temperatures can slow curing. Ensure the workspace has adequate ventilation.
The substrate likely required a stronger dilution or wasn't cleaned thoroughly. Re-clean and re-apply a fresh coat.
Ensure the primer is fully touch-dry before applying your finish; do not apply while the surface is wet.
To achieve the best results, start by ensuring the target surface is structurally sound, clean, and entirely free of oil, grease, or loose debris. Use a stiff brush or vacuum to clear the surface before application. Dilute the PrimeMate concentrate with water at a 1:3 ratio, adjusting if specific substrate porosity requires a different concentration. Apply the primer evenly using a high-quality brush or a short-nap roller to avoid pooling. Once applied, the surface should be left to dry until it reaches a tacky state. Clean all tools immediately with water after application, as the product is designed to cure into a high-strength bond that is difficult to remove once dry.
