Coverage shown is for estimating purposes only. Actual jobsite coverage may vary according to substrate conditions, concrete profile and porosity, type of equipment used, thickness applied, handling and application procedures.

FEATURES AND BENEFITS

▪ Ready-to-use gray latex, which is easy to apply with a roller or brush
▪ One-component, versatile primer for a wide variety of substrate conditions
▪ Single-coat application for faster turnaround and lower installation costs
▪ Low-odor and VOC compliance – great for use in interior, occupied environments
▪ 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
▪ Ideal primer for use with MAPEI’s SLUs
▪ Provides excellent bond strength with resistance to moisture and aging
▪ No shotblasting or abrasion required, thus eliminating the resulting dust

WHERE TO USE

▪ 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-modified mortars or SLUs.
▪ Use over substrates that have a residue of well-bonded old cutback adhesive, floor-covering adhesive or polyurethane adhesive. Refer to the “Surface Preparation” section below.
▪ 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

LIMITATIONS

▪ Substrate and ambient temperatures must be between 50°F and 95°F (10°C and 35°C).
▪ Test the concrete substrate using a calcium chloride test (ASTM F1869) to ensure that the moisture vapor emissions rate (MVER) is below 5 lbs. per 1,000 sq. ft. (2.27 kg per 92.9 m ) per 24 hours.
▪ Verify that the substrate is free of bond-inhibiting or bond-breaking materials, such as curing compounds and dust.
▪ For use in interior residential and commercial as well as exterior residential Environmental Classifications, including Res 1, 2, 3 and 6 and Com 1, 2 and 3 as outlined in the TCNA Handbook. Do not apply on wet substrates.
▪ Do not dilute.
▪ Do not install over any substrates containing asbestos.
▪ Do not install over concrete with curing compounds, sealed Saltillo tile or fiber-reinforced plastic (FRP) panels.
▪ The surface temperature of the prepared substrate must be at least 5 degrees Fahrenheit (2.8 degrees Celsius) above the dew point to avoid condensation on the surface as the ECO Prim Grip dries.
▪ Protect from freezing.
▪ When ECO Prim Grip and crack-isolation or waterproofing membranes are used in conjunction with SLUs, ECO Prim Grip should first be applied to the substrate; this should be followed by the leveler being applied over ECO Prim Grip, and then the crack-isolation or waterproofing membrane being applied over the leveler.
▪ When ECO Prim Grip is used for substrate preparation before application of waterproofing or crack-isolation membranes, the textured surface of ECO Prim Grip must be smoothed first by applying an approved patching material before rolling on liquid-applied membranes or primers for sheet membranes. Because of the coarse surface of ECO Prim Grip, if liquid membranes are installed directly over the resulting aggregate surface, an extremely heavy coating of the membranes would be required to completely encapsulate the aggregate and deliver the specified mil thickness detailed for product performance. Peel-and-stick membranes need the smoothed surface to achieve the required level of adhesion for proper bonding.
▪ Do not use for installations subject to water immersion, such as pools and spas.
▪ Use before application of polymer-modified mortars or SLUs over sound, stable and nonabsorbent substrates including ceramic tile, natural-stone floors, glass tile, cement terrazzo, cement-based agglomerates, glazed cement masonry units, VCT, well-bonded sheet vinyl flooring, rigid fiberglass, wellbonded old cutback adhesive, floor-covering adhesive residue, polyurethane adhesive residue, exteriorgrade plywood on floors, smooth nonabsorbent concrete, absorbent concrete, steel-troweled concrete, concrete with up to 20% fly ash, dry shake hardener, radiant-heated floors, gypsum substrates, gypsumbased SLUs and plastic laminate countertops.
▪ Use before the application of render coats over concrete, brickwork and concrete block substrates.
▪ Use over epoxy flooring to install carpet followed by a minimum 1/16″ (1.5-mm) layer of cement-based skimcoat or leveling compound above the highest point of the texture. Then apply Ultrabond ECO 185 or Ultrabond ECO 220 to bond carpet.
▪ Stone tile coated with a backing of epoxy resin, of epoxy resin with fiber reinforcement or of epoxy resin with an aggregate broadcast can be primed with ECO Prim Grip for interior residential to light commercial and exterior residential applications. After the bond-promoting primer is allowed to dry, MAPEI polymermodified mortars meeting specifications referred to in the “Installing Follow-up Materials” section of this Technical Data Sheet are approved for use to install this type of stone. ECO Prim Grip is not recommended for exterior facades, installations subjected to commercial traffic or severe freeze/thaw conditions; instead, epoxy setting systems are required for such applications. Consult MAPEI’s Technical Services Department for installation recommendations regarding substrates and conditions not listed.

SURFACE PREPARATION

▪ All substrates must be structurally sound, stable, dry, clean, and free of any substance or condition that may reduce or prevent proper adhesion.
▪ Thoroughly clean all surfaces of any substance that could interfere with the bond of the installation material, including paint, asphalt, wax, oil, sealers, curing compounds, and poorly bonded or incompatible adhesive.
▪ Repair cracks in the substrate before proceeding.
▪ Expansion and movement joints must be honored though the finished flooring system.
▪ Do not acid-etch surfaces before applying ECO Prim Grip.
▪ See the “Surface preparation requirements” reference guide in the Tile & Stone Installation Systems section of MAPEI’s Website.

MIXING

Before product use, take appropriate safety precautions. Refer to the Safety Data Sheet for details.
▪ Before use, stir to ensure that settling has not occurred during shipment or storage.
▪ ECO Prim Grip is ready to use; no dilution is required.

PRODUCT APPLICATION

Read all installation instructions thoroughly before installation.

1. Apply ECO Prim Grip with a 3/8″ (10 mm) nap roller or brush. Ensure that the surface receives a complete, thin film of product.
2. Polymer-modified mortar or render coat may be applied once ECO Prim Grip is dry. The minimum waiting time is from 15 to 60 minutes, depending upon the surrounding conditions and substrate porosity.
3. If completed coverage hasn’t been achieved or the original surface is visually showing through, a second coat can be applied after a longer period of time, typically after 2 to 3 hours.
4. An SLU may typically be applied within 2 to 5 hours after the ECO Prim Grip has been applied. Drying times will vary depending on surface porosity, temperature and humidity. The maximum time allowed until installation of the SLU is 24 hours.
5. If ECO Prim Grip dries for more than 24 hours before application of the SLU, re-apply a second, undiluted coat and install the SLU within the correct application window.

CLEANUP

▪ Clean equipment immediately. While ECO Prim Grip is still fresh, it can be removed easily from floors, walls and tools with water. Mineral spirits may be used to remove primer that has dried on tools.
