MAPEI ECO Prim Grip,ready-to-use, low-VOC, bond-promoting primer, enhances performance and adhesion of mortars to existing ceramics and difficult-to-bond-to substrates, improves bonding of self-leveling underlayments (SLUs) and bonds of render coats over cementitious substrates, easy, low-odor application 1 gallon (3.79l) jug

Use for both interior and exterior applications
Use over ceramic tile, porcelain tile, vinyl composition tile (VCT), well-bonded sheet vinyl flooring, natural stone or exterior-grade plywood substrate before applying polymer-modied mortars or SLUs.
Use over substrates that have a residue of well-bonded old cutback adhesive, floor-covering adhesive or polyurethane adhesive
Use to improve the bond of SLUs on nonabsorbent surfaces such as ceramic tile, cement terrazzo and nature-stone floors
Use before application of SLUs over sound and stable concrete substrates, whether they are smooth and nonabsorbent, or profiled and absorbent
Suitable for improving the bond of all types of cement render coats on concrete, brickwork and concrete block substrates
One-Component, ready-to-use gray latex, which is easy to apply with a roller or brush to a wide variety of substrate conditions
Provides a rough keying surface ideal for polymer-modified mortars, render coats and leveling compounds, ensuring excellent bonding on smooth or low-absorptive substrates
Easy handling and application properties
No shotblasting or abrasion required, thus eliminating the resulting dust
