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.
