Rapid Set

TXP™ SuperFast

Super Fast Cure, 100% Solids, Two-Component, Alkali Resistant Epoxy Primer

DESCRIPTION: Rapid Set® TXP™ SUPERFAST is a two-component, 100% solids, high performance, ultra-fast-setting, epoxy primer. It is designed for use with Rapid Set® TRU® flooring products. TXP SUPERFAST has been specially formulated to have excellent substrate wetting capabilities to promote penetration and adhesion. Overlayment can be placed in as little as 2.5 hours at 70°F (21°C). TXP SUPERFAST is moisture tolerant and resistant to elevated pH levels. It is not designed to be a moisture vapor barrier.

SURFACE PREPARATION: TXP SUPERFAST is used on properly prepared concrete. Surface must be dry, porous, clean, sound, and free of grease, oil, curing compounds, dust, mastic and other contaminants or bond breakers. Mechanically profile the surface to achieve ICRI Concrete Surface Profile (CSP) 3-5. Shot blasting is the best method to prepare the substrate. Acid etching the concrete surface is not permitted. Upon completion of mechanical preparation, remove all shot, dust, dirt and debris. Determine the substrate Moisture Vapor Emission Rate (MVER) per ASTM F1869 prior to placing TXP SUPERFAST. Acceptable substrates have an MVER less than or equal to 10 lbs/1,000 sq ft per 24 hours and relative humidity less than or equal to 100%.

MIXING: TXP SUPERFAST is a fast-cure epoxy designed for fast-track projects. Organize work so that all personnel and equipment are in place before mixing. For 2.2-gallon kits, remove TXP SUPERFAST Part B and the liner from the can to reveal TXP SUPERFAST Part A. Mix Part A for 2 minutes with a drill and Jiffy-type paint mixer. Add the entire contents of Part B to the entire contents of Part A and mix for an additional 2 minutes if material temperatures are 60-90°F (16-32°C). If material temperatures are 40-60°F (4-16°C), mix for 3 minutes after combining parts A and B. Proper proportioning and homogenization are absolutely critical for success; do not attempt to mix partial kits. Use the drill and Jiffy-type mixer to mix at slow speed (less than 500 rpm) to avoid air entrainment. Do not hand mix. Ensure that the material from the sides and bottom of the container has been thoroughly mixed in.

PLACEMENT: Upon completion of mixing, immediately pour the entire mixed TXP SUPERFAST kit onto the surface. Mixed material left in the bucket will rapidly generate heat and become unusable. Spread the TXP SUPERFAST with a flat squeegee to the appropriate coverage rate: 133 ft2 (12 m2) per gallon at 12 mils (0.30 mm) thickness or 160 ft2 (15 m2) per gallon at 10 mils (0.25 mm) thickness. To achieve a uniform thickness, back roll perpendicular to the squeegee application with a 1/2" (12.7 mm) nap roller. Use a paint brush for hard to reach areas. Immediately broadcast with clean, dry silica sand (#20 or #30 mesh) to rejection [approximately 50 lbs to 75 lbs per 100 ft2 (2.4 kg to 3.7 kg per m2)]. All sand must be completely broadcast in less than 15 minutes at 70°F (21°C) or 7 minutes at 90°F (32°C). Sweep and vacuum to remove all loose sand after a minimum curing period of 2.5 hours. Areas that are bare or not seeded to rejection must be recoated. Within 12 hours, those areas may be reprimed and rebroadcast. After 12 hours, those areas must be mechanically abraded, primed, broadcast and cured prior to proceeding.

Surface and ambient temperatures must be between 40°F and 90°F (4°C and 32°C). At 70°F (21°C), TXP SUPERFAST has a working time of 10 minutes. Higher temperatures will significantly shorten the pot life, working time, and sand receiving time. Lower temperatures will extend the working time and may delay the time in which loose sand may be removed.

JOINTS & REPAIRS: Non-moving cracks may be filled with the TXP SUPERFAST epoxy. For spalls, prime the surface with TXP SUPERFAST, then fill with epoxy mortar made using a mixture of 1 part TXP SUPERFAST and up to 5 parts dry, graded sand by volume. Once the repair area has been filled, continue with the application coat of the TXP SUPERFAST and subsequent system installation in accordance with product requirements. All moving joints must be honored through the finished floor and filled with an appropriate joint sealant or filler. TXP SUPERFAST should not be used in expansion joints, isolation joints, construction joints or any moving cracks.

CLEAN-UP: Use acetone to remove TXP SUPERFAST from tools and surrounding areas before it hardens.

COVERAGE & PACKAGING: TXP SUPERFAST is available in 1-gallon (3.8 L) and 2.2-gallon (8.3 L) kits. Coverage is 160 ft2 (15 m2) per gallon at 10 mils (0.25 mm) thickness. Coverage rate is approximate and will vary due to the porosity and surface profile of the concrete substrate.

SHELF LIFE: TXP SUPERFAST has a shelf life of 18 months when stored properly in a dry location, protected from moisture, out of direct sunlight, and in an undamaged package.

USER RESPONSIBILITY: Before using CTS products, read current technical data sheets, bulletins, product labels and safety data sheets at www.CTScement.com. It is the user’s responsibility to review instructions and warnings for any CTS products prior to use. Contact CTS prior to product installation when additional information is required, or when project conditions are not in compliance with specifications and/or installation requirements.

Always comply with subsequent manufacturer’s testing and installation requirements when their products are used in conjunction with Rapid Set® TRU® flooring products.

WARNING: AVOID BREATHING OF VAPORS. FORCED LOCAL EXHAUST IS RECOMMENDED TO EFFECTIVELY MINIMIZE EXPOSURE. NIOSH approved, organic vapor respirators and forced exhaust must be used in confined areas, when conditions (such as heated polymer, sanding) may cause high vapor concentrations, or when applying large volumes. Hazardous vapor is released when an epoxy is burned. Avoid skin or eye contact. Wash skin with soap and water if contact occurs. If eye contact occurs, flush with water for 15 minutes and obtain medical attention. Read and understand all cautions on container labels and safety data sheets before using this material.
