SikaWall® Super Blockade

SikaWall® Super Blockade

Formerly LaHabra® Super Blockade.

A polymer modified, one component, waterproofing coating for use over Portland cement, concrete and masonry surfaces. It is designed to fill and seal the pores and voids of the surface being treated to prevent the intrusion of moisture. When properly applied, SikaWall® Super Blockade becomes an integral part of the wall.

  • Requires only water for mixing.
  • Simple application
  • Eliminates leakage caused by moisture saturation.
  • Assists in preventing moisture damage such as; efflorescence, spalling, crumbling, discoloration, etc.
  • Non-Toxic, VOC compliant.

Usage

SikaWall® Super Blockade waterproofs portland cement surfaces above and below grade such as: plaster brown coat, concrete block, poured in place concrete, pre-cast concrete, tilt-up walls, brick and stone. Ideal protection for: Cement, plastered walls, concrete foundations, block walls, reservoirs, tunnels, bridges, water tanks, brick structures or any other concrete, cement or masonry surface subject to moisture related damage. Ideal protection for block walls prior to back-filling. Super Blockade is normally applied to the surface exposed to the moisture.

Application

Consumption

Coverage

Coverage rate or amount of SikaWall® Super Blockade required to complete the job will depend on the surface porosity, texture and thickness. At 1/16 inch (1.5 mm) thickness a 50 lb (22.6 kg) bag will cover approximately 200 sq. ft. (18.6 m2). Two coats are required for the positive (source of moisture) side, or two coats or more for the negative side.
Application steps

SUBSTRATE PREPARATION

  • All receiving surfaces must be structurally sound, clean, free of dust and dirt, silicones, paint products, efflorescence, or any other contaminant that 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 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.
  • Painted surfaces must be clean and all PAINT REMOVED. Surface pores should be open to allow for 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 SikaWall® Super Blockade. It must be mechanically mixed at a slow speed to produce a smooth workable conistency.
  • Pour about half the required water into a clean container and begin slow speed mixing while slowly adding SikaWall® Super Blockade. Gradually add more SikaWall® 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 remix. If necessary, add more water to achieve a brushing consistency.

APPLICATION

  • Surfaces being treated should be evenly wetted with clean water to control suction. Apply SikaWall® Super Blockade with either a 6“ (15 cm) masonry brush or a tampico bristle 10” (25 cm) push broom. After loading bristles, apply a heavy coat using long, even, horizontal strokes so that all surface pores and voids are filled. Ensure the material is evenly distributed to avoid excessive build-ups.
  • Important: Brush strokes must be in one direction only. For maximum protection, apply a second coat in the same fashion after the first coat has set up.
  • Allow 12 to 24 hours between coats, not more than 24 hours.
  • Note: SikaWall® Super Blockade is normally applied to the surface exposed to the moisture.
