Products : Flooring Installation Systems : Leveling : CL-XP1
This product has been discontinued. Please reference our CustomTech line of products.
CL-XP1™ is a high strength, low prep self-leveling underlayment that levels floors prior to the installation of ceramic tile, natural stone tile, resilient flooring, carpet, wood and other floor coverings. This quick-setting underlayment can be applied to 2" (5 cm) thick in one pour and seeks its own level in minutes. Formulated to have high compressive strength and abrasion resistance, CL-XP1 achieves an extra heavy rating for high impact use in food plants, hospitals, and kitchens. CL-XP1 may be applied to in residential structures with floor joists up to 24" (61 cm) o.c. Formulated using Controlled Cure Technology,™ CL-XP1 helps eliminate installation problems such as bond failure, crumbling and staining of resilient flooring caused by the free moisture found in traditional underlayments.
Suitable as an Underlayment for:
ASTM International (ASTM)
Resilient Floor Covering Institute (RFCI) Recommended Work Practices for Removal of Resilient Floor Coverings
Tile Council of North America (TCNA) TCNA Handbook for Ceramic Tile Installation, TCNA Method EJ171
American National Standards Institute (ANSI) ANSI A108.01 and A108.02 of the American National Standards for the Installation of Ceramic Tile
Installation must comply with the requirements of all applicable local, state and federal code jurisdictions.
CL-XP1 is a dry, proprietary blend of co-polymers, cements and inorganic chemicals.
Custom Building Products is committed to environmental responsibility in both products produced and in manufacturing practices. Use of this product can contribute to LEED® certification
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. Concrete surfaces should be primed with an appropriate Custom® primer. Smooth concrete surfaces, existing glazed tile, terrazzo, or polished stone may need to be roughened or scarified and treated with an appropriate Custom® primer. For increased performance in demanding applications, concrete surfaces can be mechanically profiled and prepared by shotblasting, sandblasting, water-jetting, scarifying, diamond-grinding or other engineered approved methods (reference ICRI CSP 3 standards for acceptable profile height).
Prime all surfaces with an appropriate Custom® primer before application.
Joints or Cracks in Substrate
Expansion joints and cold joints, as described in ANSI A108.01, should be carried from the substrate up through the tile or flooring surface and filled with an appropriate elastomeric sealant, such as Custom's® 100% Silicone Caulk. For the proper treatment of control or saw cut joints and cracks for flooring, refer to ASTM F710. For tile installations, refer to TCNA Details EJ171, F125,& F125A. Contact Custom's® technical services for additional information.
This product contains Portland 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 must be free of efflorescence and not subject to moisture beyond the floor covering manufacturers' limits or hydrostatic pressure. Lightweight concrete surfaces must have a tensile strength in excess of 200 psi (1.4 n/mm²).
Plywood floors, including those under resilient flooring, must be structurally sound and must meet all industry guidelines. For questions about proper subfloor installation, call Custom Technical Services. A 2.5 lb/yd² metal lath must be fastened every 6" - 8" (15 - 20 cm) with fasteners that have a galvanized or corrosion-resistant coating over primed surfaces.
OSB underlayments should be coated with 10-15 mils of RedGard® Waterproofing and Crack Prevention Membrane prior to priming with an appropriate Custom® primer. A 2.5 lb/yd² metal lath must be fastened every 6" - 8" (15 - 20 cm) with fasteners that have a galvanized or corrosion-resistant coating. A minimum of 1/4" (6 mm) of CL-XP1 can be applied over this properly prepared OSB.
Bonding to Gypsum Surfaces
Gypsum-based underlayments 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 must be structurally sound and subject to deflection not to exceed the current industry standards. Surfaces shall be free of all grease, oil, dirt, dust, curing compounds, waxes, sealers, efflorescence, or any other foreign matter.
All Gypsum surfaces should be primed with a properly applied sealer or a primer coat of RedGard, consisting of 1 part RedGard diluted with 4 parts clean, cool water. Mix in a clean bucket at low speed to obtain a lump-free solution. The membrane can be brushed, rolled or sprayed to achieve an even coat. Apply the waterproofing coat to the floor at a rate of 300 sq. ft.l (7.5 sq. m/L). Drying time depends on site conditions, but is normally less than 1 hour. Extremely porous surfaces may require 2 coats. At this point, an appropriate Custom® primer and CL-XP1 can be applied to the primed lightweight or gypsum based surface. Refer to the individual product data sheet or packaging directions for application instructions. Expansion joints must be installed in accordance with local building codes and industry guidelines.
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.
Mix the entire 50 lb (22.68 kg) bag of powder with 5.0 - 5.5 quarts (4.7 - 5.2 L) of clean, cool water.
Barrel:Mix 50 lb. (22.68 kg) bag of powder with an appropriate amount of clean, cool water. Slowly add powder to water while mixing with a heavy-duty 1/2" (13 mm) electric drill and an “egg-beater” mixing paddle at 800 - 1200 RPM. Thoroughly mix for 2 minutes to a lump-free consistency. Do not overmix. Overmixing or moving the mixer up and down during the mixing process could trap air, which could shorten the pot life or cause pinholing during application and curing.
Pumping:CL-XP1 can be pumped with an appropriate mixing pump. Adjust the water setting to obtain the optimum workability. Do NOT overwater.
Apply an appropriate Custom® primer according to the specifications in the respective technical data sheet for each product. Pour or pump CL-XP1, then spread with a long-handled gauged spreader. Will flow during the first 20 minutes. For featheredging and touch-ups, use a smoothing tool. Can be applied up to 2" (5 cm) thick in one application. If a second layer is required, install immediately after the first layer has set to a walkable hardness. If the first layer has dried over 12 hours, re-prime before second application. Dries to a walkable hardness in 2 - 4 hours. For pumping and large scale applications, contact Custom's Technical Services Department for more information.
Install non-moisture-sensitive ceramic tile or stone in 4 hours; most floor coverings can be installed after 16 hours. Drying time can vary with temperature and humidity. Test for moisture content before applying vinyl or wood flooring to the surface of the self-leveler.
Clean with water before material dries.
Properly installed product requires no special maintenance.
