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.
