Cementitious Waterproofing

Name		Super Blockade
Type		One Component Cementitious Waterproof Coating For Concrete and Masonry
Application Method		Brush applied.
Product Overview		Super Blockade is a proprietary formulation of portland cements, graded aggregates and chemical additives. The correct amount of co-polymer powder is pre-mixed in the bag, so only water is required to achieve consistent waterproofing of portland cement surfaces.
Benefits		Convenient. No liquid polymers to buy, inventory or handle. Eliminates leakage caused by moisture saturation. Prevents moisture damage such as efflorescence, spalling, crumbling, and discoloration. Mixes easily with mechanical mixer at slow speed. Simple application by masonry brush or bristle push broom. Serves as final white or gray decorative surface as it protects. Long term protection. Eliminates need for concrete rubbing or sacking. Foolproof waterproofing, eliminates mixing mistakes.
Placement		Super Blockade may be applied above or below grade. Two coats are recommended for the positive (source of moisture) side, or two coats or more for the negative side.
Substrates		It is effective on plaster brown coat, concrete block, poured-in-place concrete, precast concrete, tilt-up walls, brick and stone.
Examples of Use		Recommended uses include protecting cement plastered walls, concrete foundations, block walls, reservoirs, tunnels, bridges, water tanks, brick structures, and any other concrete, cement or masonry surface subject to damage from moisture.
Components and Storage		Available in 50 lb. (22.68 kg.) pails or bags, in white or gray. Super Blockade must be kept in dry storage area. Shelf life is one year if properly stored.
Coverage		Varies with surface porosity, texture and application thickness. At 1/16 inch (1 .5mm) thickness, 2 Ibs. (0.9 kg.) covers approximately 1 sq. yd .(0.84 m2); 50 lb. (22 .25 kg.) bag covers approximately 200 sq. ft.(18.4 m2).
Surface Preparation		All receiving surfaces must be structurally sound, clean, free of dust, dirt, silicones, paint products, efflorescence or any other contaminant which could hinder bonding ability. Allow new cement and masonry surfaces to fully cure (approximately 28 days) prior to application. Surface cracks, holes or voids should be repaired. Smooth or painted surfaces must be cleaned in an abrasive manner (high pressure water blast, scraping, sanding or sandblasting) to open surface pores and allow for a good bond.
Mixing		Approximately 1.5 to 2 gallons (5.5 to 7.5 Itr) of clean, potable water are required for each 50 lb. (22.25 kg) bag of Super Blockade. It must be mechanically mixed at a slow speed to produce a smooth workable consistency. Pour about half the required water into a clean container and begin slow speed mixing while slowly adding Super Blockade. Gradually add more Super Blockade and water and bring the mixture to the consistency of heavy pancake batter. Do not over air entrain with excessive mixer speed. Stop mixing and allow mixed material to stand (fatten) for 10 minutes and then finish mixing (re-temper). If necessary, add more water to achieve a brushing consistency.
Application		Evenly wet substrate with clean water to control suction. Apply with 6" (15 cm) masonry brush or 10" (25 cm) tampico bristle push broom. Apply a heavy coat using long, straight horizontal brush strokes in one direction only. Fill all pores and voids. Distribute evenly and avoid excessive build-ups. For maximum protection, allow 12 to 24 hours and apply a second coat.
Clean Up		Water and detergent. Clean spills and spatters before Super Blockade dries.
Limitations		Do not apply over frozen or frost filled surfaces. Do not use when ambient temperature will fall below 40° F (4° C) within 48 hours after application. Do not apply to traffic bearing surfaces. Allow Super Blockade to cure for at least 7 days before filling spas, pools and tanks.
