Sulfate-Resistant, Vertical, Overhead and Horizontal Repair Mortar with Silica Fume Planitop 12 SR is a sulfate-resistant, one-component, shrinkage-compensated, cementitious repair mortar. Planitop 12 SR is fiber-reinforced, contains both silica fume and a corrosion inhibitor, and is intended for the repair of vertical, overhead and horizontal concrete surfaces.

• Resistant to sulfate attack, which can deteriorate concrete and reduce concrete strength
• Fiber-reinforced, to provide greater tensile strength and control of cracking
• Higher resistance to abrasion than ordinary repair mortars can offer
• One-component system that requires only the addition of potable mixing water
• Can be applied using a trowel or a low-pressure spray pump
• Strong bond to old concrete surfaces, and good resistance to freeze/thaw conditions and de-icing salts
• Can be used between temperatures of 45°F and 95°F (7°C and 35°C)
• Modified with silica fume for higher strength and durability
