DEEP LEVEL is a two component, acrylic polymer modified, cement based patching material for horizontal concrete substrates. The 50 lb. bag of dry mortar component is a blend of Portland cement, graded silica sands and water reducing agents. When mixed with ACRYLIC ADDITIVE, the resulting DEEP LEVEL mortar produces an extremely strong, durable, crack resistant patching material with outstanding bond strengths. DEEP LEVEL is used to repair spalls, joint shoulders as well as fill wide cracks and low spots on horizontal concrete slabs. DEEP LEVEL may also be used to resurface horizontal concrete, above or below grade or serve as a leveling underlayment for XCEL Surfaces texture coating systems. DEEP LEVEL is suitable for both interior and exterior service.
