Merlex Super Blockade
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. 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 and is Brush applied.
