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, and 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 lbs. (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 ltr) 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
second coat.
|
|
|
|
|
|
Clean
Up
|
|
Water
and detergent. Clean up 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 40º F (4º 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 water tanks
with water. |
