(*Preparation required)
USE CHEMICAL-RESISTANT GLOVES, such as nitrile, when handling product.
All surfaces must be structurally sound, clean, dry and free from contaminants that would prevent a good bond. Concrete must be fully cured. Refer to final flooring manufacturer's requirements for maximum moisture vapor transmission limitations. Smooth concrete surfaces, existing glazed tile, terrazzo, or polished stone may need to be roughened, scarified or used with CustomTech™ TechPrime A Acrylic Primer or CUSTOM® MBP Multi Surface Bonding Primer. For increased performance in demanding applications, concrete surfaces can be mechanically profiled and prepared by shotblasting, sandblasting, scarifying, diamond- grinding or other engineered approved methods (reference ICRI CSP 3 standards for acceptable profile height).
This product contains cement. 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. Use with adequate ventilation; do not breathe dust and wear a NIOSH approved respirator. If ingested, do not induce vomiting; call a physician immediately.
Contaminants or curing compounds should be mechanically removed before installation. Concrete & masonry must be free of efflorescence and not subject to moisture beyond the floor covering manufacturers' limits or hydrostatic pressure. Concrete surfaces must have a t ensile pulloff strength in excess of 200 psi (1.4 n/mm²).
Gypsum-based underlayment must obtain a minimum 2000 psi (13.8MP) compressive strength. The underlayment must be sufficiently dry and properly cured to the manufacturer’s specifications for permanent, non-moisture permeable coverings. Surfaces must be structurally sound and subject to deflection not to exceed the current industry standards. Surfaces shall be free of all contaminates such as grease, oil, dirt, dust, curing compounds, waxes, efflorescence. All Gypsum surfaces should be treated with the manufacturer’s sealer or primed with CustomTech™ TechPrime A Acrylic Primer. Refer to the product data sheet and packaging directions for application instructions.
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. Refer to the RFCI Pamphlet, "Recommended Work Practices for Removal of Resilient Floor Coverings", for further information.
Mix 3 ½4 quarts (3.313.78 L) clean, cool water to a 40 lb. (18.14 kg) bag of TechPatch RP.
Slowly add powder to liquid while mixing with a high speed drill (650 RPM or more) and mixing paddle to a lump-free consistency. Mix amounts that can be applied in 20 minutes.
Lightly dampen porous substrates with a sponge to remove dust and assist bonding. Pressure-apply TechPatch RP with a smooth edged trowel. Add more product as desired to flatten the surface. Use a straightedge in thicker applications to place, level or flatten patch to the appropriate elevation.
Allow to cure for 60 – 90 minutes. Drying time will vary based on thickness, temperatures and humidity.
Clean with water before material dries.
Properly installed product requires no special maintenance.
