RHOA Primer in Jet Black color

RHOA Primer™ - Jet Black color is a high-performance bonding base coat engineered to properly prepare surfaces for the RHOA system and ensure maximum adhesion of RHOA Plaster. It features a 100% acrylic formulation with superior bonding strength, fast dry time, and exceptional multi-surface compatibility.

Designed as a professional-grade substrate conditioner, RHOA Primer seals porous surfaces, blocks uneven absorption, and creates a uniform film build that enhances plaster workability and consistency. Its advanced composition offers excellent hide, mildew-resistant coating, and moisture resistance—critical for maintaining surface stability and preventing defects in high-end architectural finishes.

Each bottle is designed to pair with one bucket of RHOA Plaster (24 sq ft coverage), forming the essential first step in the complete RHOA system alongside Plaster, Film, and Sealer for a consistent, high-end result.
