Products : CustomTech Flooring Prep : CustomTech Flooring Prep : TechPrime A Acrylic Primer
TechPrime A is an advanced acrylic primer and sealer that prepares surfaces for the application of an appropriate Custom® or CustomTech™ self-leveling underlayment. It seals porous and non-porous surfaces and improves the bond of the underlayment to the subsurface.
Installation must comply with the requirements of all applicable local, state and federal code jurisdictions.
Custom® Building Products is committed to environmental responsibility in both products produced and in manufacturing practices. Use of this product may contribute to LEED® certification.
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. Glossy or painted surfaces must be sanded, stripped and cleaned of waxes, dirt or any contaminants. Concrete must be cured 28 days and accept water penetration. Concrete must be free of efflorescence and not subject to hydrostatic pressure. Concrete slabs should have a broomed or brushed finish to enhance the bond. Plywood flooring including those under resilient flooring must be structurally sound and meet all ANSI and deflection requirements. For questions about proper subfloor installation, call Technical Services. Smooth concrete surfaces, existing glazed tile, terrazzo or polished stone should be roughened or scarified. Do not sand flooring materials containing asbestos. 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.
Bonding to Concrete Surfaces
Concrete must be cured 28 days. Concrete must be free of efflorescence and not subject to a hydrostatic pressure or moisture vapor transmission rate exceeding floor covering manufacturer’s recommendations. Concrete slabs should have a broom or brushed finish to enhance the bond. Concrete must accept water penetration. Test by sprinkling water on various areas of the substrate. If water penetrates, then surface is ready for the primer; if water beads, surface contaminants are present, and loss of adhesion may occur. Contaminants should be mechanically removed before installation.
Expansion joints and cold joints, as described in ANSI A108.01, must be honored. They must be brought through the applied system and filled with an appropriate elastomeric sealant, such as Custom's® 100% Silicone Caulk. Contact Custom's Technical Services for the proper treatment of control or saw cut joints. Refer to TCNA EJ171, F125 & F125A.
Stir and use undiluted for non-porous surfaces.
Dilute up to 3 parts water to 1 part primer with clean, potable water for highly porous concrete surfaces.
Contains acrylic emulsion. Wear suitable gloves and eye protection. Avoid eye contact or 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.
Do not bond directly to hardwood, Luan plywood, particle board, parquet, cushion or sponge-back vinyl flooring, metal, fiberglass or plastic.
Plywood floors, including those under resilient flooring, must be structurally sound and must comply with all applicable building standards based on floor covering. For questions about proper subfloor installation, contact Custom's® Technical Services.
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 Tech MVC Moisture Vapor and Alkalinity Barrier
Moisture vapor control epoxy coatings must be fully cured and free of pinholes and blisters before applying TechPrime A. Do not dilute the primer. Spread with a short nap roller at an approximate coverage rate of 400 square feet per gallon.
Since settling may occur, stir using a low speed (300 rpm) power mixer; do not over-mix and do not entrain air.
Apply with a paint brush, short nap roller or a soft push broom. Apply a thin, even coat; do not allow puddling. Allow to dry to a clear film (1 to 3 hours, depending on ambient conditions and dilution) before applying an appropriate Custom® or CustomTech™ self-leveling underlayment. Highly porous concrete surfaces may require a second coat of diluted primer.
Clean with water before the material dries.
Store in a cool, dry area. Keep from freezing.
Properly installed product requires no special maintenance.
