TechLevel 125 Deep Pour Self-Leveling Underlayment

TechLevel 125 is a high quality, self-leveling underlayment that achieves up to 4,000 psi compressive strength. TechLevel 125 levels floors prior to the installation of resilient flooring, carpet, wood, ceramic tile, natural stone tile and other floor coverings. This quick setting underlayment can be applied 1/4" to 3" (7.6cm) thick in one pour and seeks its own level in minutes. Formulated to have excellent physical strength, TechLevel 125 may be applied in residential structures with floor joists up to 24" (61 cm) o.c. Formulated using Controlled Cure Technology™, TechLevel 125 helps eliminate installation problems such as bond failure, crumbling and staining of resilient flooring caused by the free moisture found in traditional underlayment.

General Surface Prep

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 CustomTech™ primer. Smooth concrete surfaces, existing glazed tile, terrazzo, or polished stone may need to be roughened or scarified. 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).

Priming

Prime all surfaces with an appropriate CustomTech™ primer before application of TechLevel 125. 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 Sealant. 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.

Health Precautions

See Safety Data Sheet for complete safety 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. Conformance to Building Codes Installation must comply with the requirements of all applicable local, state and federal code jurisdictions.

Limitations to the Product

  • For interior use only.
  • Do not use when the temperature is below 50° F (10° C), or above 90° F (32° C).
  • Do not bond directly to hardwood, Luan plywood, particle board, parquet, cushion or sponge-back vinyl flooring, metal, fiberglass or plastic. Contact technical services for recommendations.
  • Do not use as a permanent wear surface.
  • Do not use on sloped surfaces that require drainage.
  • Precautions should be taken when applying over post-tensioned concrete, pre-stressed concrete or prefabricated concrete planks. Contact technical services for further details.

Bonding to Concrete Surfaces

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).

Bonding to Lightweight Cement and Gypsum Surfaces

Gypsum-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 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./gal (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 CustomTech™ primer and TechLevel 125 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.

Bonding to Plywood Surfaces

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 surface. OSB underlayments should be coated with 10-15 mils of RedGard® Waterproofing and Crack Prevention Membrane prior to priming with an appropriate CustomTech™ 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 TechLevel 125 can be applied over this properly prepared OSB.

Bonding to Cutback Adhesive

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.

Mixing Ratios

Mix the entire 50 lb (22.68 kg) bag of powder with 4.25 – 4.5 quarts (4-4.25 L) of clean, cool water.

Mixing Procedures

Barrel: Mix 50 lb. (22.68 kg) bag of powder with the appropriate amount of clean, cool water. Slowly add powder to water while mixing with a heavy­duty 1/2" (13 mm) electric drill and an “eggbeater” mixing paddle at minimum 650 RPM. Thoroughly mix for 2 minutes to a lumpfree 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: TechLevel 125 can be pumped with a mixing pump. Adjust the water setting to obtain the optimum workability. Do NOT overwater. Pump the mix and use spreader to evenly distribute the materials to desired thickness.

Application of Product

Apply an appropriate CustomTech™ primer according to the specifications in the respective technical data sheet for each product. Pour or pump TechLevel 125, then spread with a long-handled gauged spreader. TechLevel 125 will seek its own level during the first 10-15 minutes. For featheredging and touch-ups, use a smoothing tool. Can be applied 1/4" to 3.0" (7.6 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. The surface will dry to a walkable hardness in 2 - 4 hours. For pumping and large scale applications, contact Custom's® Technical Services Department for more information.

Curing of Product

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-leveling underlayment.

Cleaning of equipment

Clean with water before material dries.

Product Maintenance

Properly installed product requires no special maintenance.
