- 1. SUPERCAP™ CONCRETE CAPPING CEMENT SUPERCAP™™ THE NEXT GENERATION SLAB SUPERCAP - THE NEXT GENERATION SLAB SUPERCAP™ is a specially designed, high-performance, self-leveling, cement-based product designed for capping of interior concrete surfaces. The slab should be finished rough and open (bull-floated only) and does not need to be finished in the traditional way (power-troweling). SUPERCAP™ can be applied to new concrete as soon as three days after pour depending on factors such as mix design, jobsite conditions and end-user requirements. Finished floor goods may be installed as soon as 7 days after application of SUPERCAP™ depending on thickness, drying conditions and type of flooring materials. SUPERCAP™ CONCRETE SLAB METAL DECK PERFORMANCE CHARACTERISTICS • Pour depths of 1/8” to 1 ½” – designed to remove camber in slab or concrete surface variation • Low alkali formulation allows for quick installation of finished floor goods • SUPERCAP™ can receive floor covering in as soon as 7 days after application depending on thickness and jobsite conditions • The product is water damage stable and will not deteriorate, warp, buckle, or change shape even when soaked or exposed to high moisture conditions • Surface is walkable in 1-4 hours and may be open to construction traffic within 24 hours • Can be left open to normal trades traffic for up to 1 year prior to installation of floor coverings • Inorganic formulation will not contribute to or harbor growth of mold or mildew • Will not contribute to damaging emissions or irritating fumes upon setting or curing (in compliance with strict indoor air quality demands) TECHNICAL DATA SUPERCAP .

- 2. SUPERCAP™- THE NEXT GENERATION SLAB SURFACE PREPARATION SUPERCAP™ is formulated to be poured over properly prepared concrete slabs. The use of SUPERCAP™ eliminates the need for labor and equipment-intensive floor smoothing techniques. Any new slab can be poured at a depth approximately 1/2” lower than desired final slab height and should be finished rough and open. Bull-floating or equivalent is all that is required to prepare surface for SUPERCAP™ installation. Wax-based curing agents should not be used, since they are bond-breakers. Since leveling will be achieved using SUPERCAP™, traditional methods such as power-troweling are not required. New concrete should be allowed to dry for a minimum of 3 days prior to installation of SUPERCAP™. Relative humidity of substrate should be tested according to ASTM F 2170 and must be 95% or less. Substrate shall be free from dust, dirt, oil, grease, paint or any other jobsite contaminants which may inhibit the bond to the surface. Weak or contaminated surfaces must be mechanically cleaned by shot blasting or scarifying. Never use chemicals to clean the substrate without prior written consent from the manufacturer. Surface bond strength of the substrate should be minimum 100 psi (0.7 MPa). If required to meet level tolerances, survey surface using PTI’s LEVELMASTER and apply LEVEL PEGS. Substrate should be primed with SUPERCAP™ PRIMER (see primer literature for proper preparation and use). Substrate temperature should be a minimum 43°F (6°C) during application and ambient temperature maintained between 50-77°F (10-25°C). Adequate ventilation should be provided to ensure uniform drying. APPLICATION Pour blended material onto substrate at a thickness of between 1/8” to 1 ½” (3-38mm) for all surfaces except lightweight concrete, where a thickness of 1/4” to 3/8” (6-10mm) must be maintained. Perform slump test and adjust water accordingly until ideal patty size of 10-11 inches for SUPERCAP™. Immediately smooth the poured slurry with a gauge rake, notched trowel or smoother. Material can be walked on after 1-4 hours. FLOORING INSTALLATION Finished floor material may be installed as soon as 7 days over SUPERCAP™ after application, depending on thickness, drying conditions and type of finished floor. Due to the relatively low pH level of SUPERCAP™, finished floor goods can be applied rapidly without risk of adhesive bond failure. As a general rule, permeable materials such as carpeting may be adhesively or mechanically applied to SUPERCAP™ when RH level of substrate (i.e. concrete slab, etc) is 95% or below. Non-permeable floor goods such as VCT may be applied when the RH level of the substrate is 85% or below. Installation must allow for the eventual drying of the concrete substrate. RH levels should be determined according to ASTM standard F2170. In all cases, the recommendations of the floor covering manufacturer should be followed. LIMITATIONS For indoor applications only. Not intended for use as a wear surface. Not for applications exposed to continuous water of intrusion. STORAGE Product should be stored in dry conditions and in the original packaging.

WARNING: Dust may cause skin, eye nose, throat, or reparatory irritation. Avoid dust inhalation and exposure to dust. If dusty, wear a NIOSH/MSHA-approved dust respirator. Use proper ventilation to reduce dust exposure. Portland cement is strongly alkaline and can be corrosive to eyes, skin and respiratory tract. Wear eye and skin protection. If eye contact occurs, immediately flush thoroughly with water for 15 minutes and get medical attention. Do not ingest. If ingested and any discomfort occurs, call physician.
