MAPEI ECO Prim Grip - Ready-to-Use Low-VOC Bond-Promoting Primer (1 gal)

MAPEI ECO Prim Grip is a ready-to-use, low-VOC primer designed to promote adhesion across a broad range of substrates. The formula features silica aggregates suspended in a latex dispersion, creating a subtle key that helps mortars and leveling compounds grip more securely. The result is a versatile prep product that supports strong bonding without the mess of heavy preparation steps. The gray, easy-to-apply paste glides onto surfaces with a smooth, even finish, and its low-odor profile makes interior jobs more comfortable from start to finish.

In practical terms, ECO Prim Grip shines when you’re preparing surfaces for mortars on ceramic and non-absorbent substrates, or when bonding self-leveling underlayments (SLUs) and render coats over cementitious substrates. Its moderate texture helps underpin polymer-modified mortars, render coats, and leveling compounds, while its low-VOC composition keeps indoor air clearer during prep work. The product is suitable for both interior and exterior projects, and its one-component formulation simplifies handling on a variety of job sites, from bathrooms to foyers, and from kitchens to exterior patios.

Key surfaces and conditions

• Use over ceramic tile, porcelain tile, vinyl composition tile (VCT), well-bonded sheet vinyl flooring, natural stone, or exterior-grade plywood before applying polymer-modified mortars or SLUs.
• Accepts substrates with residues of well-bonded old adhesives, such as cutback adhesive, floor-covering adhesive, or polyurethane adhesive.
• Improves bond of SLUs on nonabsorbent surfaces like ceramic tile, cement terrazzo, and natural stone floors.
• Apply before SLUs over sound, stable concrete substrates, whether smooth and nonabsorbent or textured and absorbent.
• Supports the bonding of all types of cement render coats on concrete, brickwork, and concrete block substrates.

Why choose ECO Prim Grip

• One-component, ready-to-use gray latex that is easy to apply with a roller or brush.
• Provides a rough keying surface ideal for polymer-modified mortars, render coats, and leveling compounds.
• Low-odor formula with low-VOC content for more comfortable prep work.
• No shotblasting or abrasion required, reducing dust generation and cleanup time.

How to use (brief): Ensure surfaces are clean, sound, and free of loose debris. Apply evenly with a roller or brush and allow to dry per label instructions before applying mortars or SLUs. For best results, follow project-specific guidelines for cure times and substrate preparation.
