Products : Surface Prep : Surface Primers : MBP - Multi-Surface Bonding Primer
Multi-Surface Bonding Primer (MBP) is a single-component, water-based primer engineered to deliver superior adhesion on a variety of substrates where proper bonding is difficult. Specially formulated with aggregates and polymers to promote mechanical adhesion on non-porous substrates.
Prepares surface with a textured finish that is suitable for installation with modified cement mortar and self-leveling underlayments.
Installation must comply with the requirements of all applicable local, state and federal code jurisdictions.
USE CHEMICAL-RESISTANT GLOVES, such as nitrile, when handling product.
Ambient temperature, surfaces and materials should be maintained at a temperature between 50° F (10° C) and 95° F (35° C) for 72 hours during application. Surfaces must be structurally sound, clean, dry and free from grease, oil, dirt, curing compounds, sealers, adhesives or any other contaminant that would prevent a good bond. Existing finishes must be well bonded to the substrate. Concrete must be cured. Concrete must be free of efflorescence and not subject to hydrostatic pressure. Plywood flooring including those under resilient flooring must be structurally sound and meet all building code and deflection requirements. Can be used on steel troweled finishes without scarifying. For questions about proper subfloor installation, call Technical Services.
Bonding to Gypsum UnderlaymentGypsum based underlayment must obtain a minimum 2000 psi (13.8 MP) compressive strength. The underlayment must be sufficiently dry and properly cured to the manufacturer’s specifications for permanent, non-moisture permeable coverings. Surfaces to be tiled must be structurally sound and subject to deflection not to exceed the current ANSI Standards. Surfaces shall be free of all grease, oil, dirt, dust, curing compounds, waxes, sealers, efflorescence, or any other foreign matter.
Gypsum underlayment surface must be primed with a properly applied Multi-Surface Bonding Primer at a rate of 150 sq ft per gallon before tile is installed with a cement based mortar. Expansion joints must be installed in accordance with local building codes and ANSI/TCNA guidelines. Refer to TCNA EJ171.
Contains acrylic emulsion. Wear suitable gloves and eye protection. Avoid eye contact and prolonged contact with skin. Wash thoroughly after handling. If eye contact occurs, flush with water for 15 minutes and consult a physician. If skin contact occurs, wash immediately with soap and water. Dried material is extremely difficult to remove. KEEP OUT OF REACH OF CHILDREN. DO NOT TAKE INTERNALLY.
Adhesive layers must be removed. Use extreme caution; adhesives may contain asbestos fibers. Do not sand or grind adhesive residue, as harmful dust may result. Never use adhesive removers or solvents, as they soften the adhesive and may cause it to penetrate into the concrete. Adhesive residue must be wet-scraped to the finished surface of the concrete, leaving only the transparent staining from the glue. To determine desirable results, do a test bond area before starting. Refer to the RFCI Pamphlet "Recommended Work Practices for Removal of Resilient Floor Coverings" for further information.
Bonding Over Cured Moisture Vapor and Alkalinity Barriers
Moisture vapor control epoxy coatings must be fully cured and free of pinholes and blisters before applying MBP. Do not dilute the primer. Spread with a short nap roller at an approximate coverage rate of 150-300 square feet per gallon.
Since settling may occur, stir using a low speed (200 rpm or less) power mixer for 30-60 seconds; do not over-mix and do not entrain air.
Apply with a paint brush, 1/4" or 3/8" nap roller. Apply a thin, even coat at a uniform coverage rate of 150-300 ft per gallon; do not allow puddling.
Allow for MBP to dry (1 to 3 hours, depending on ambient conditions) before installation of leveling, tile or flooring products. Minimum dry time for polymer modified mortars is between 15 to 60 minutes. Minimum dry time for self leveling underlayment is 1 hour. Drying time may be longer depending on substrate and/or environmental conditions. If MBP is directly exposed to ambient conditions for 3 or more days, re-coat the area.
Clean with water before the material dries.
Store in a cool, dry area. Keep from freezing.
Properly installed product requires no special maintenance.
