Sikatop® 123, 17 kg Bag Only

$33.25 / BAG
SikaTop® 123 PLUS is a two-component, polymer-modified, Portland cement, fast-setting, non-sag mortar. It is a high performance repair mortar for vertical and overhead surfaces, and offers the additional benefit of FerroGard 901, a penetrating corrosion inhibitor.
• Extremely low shrinkage proven by four industry standard test methods • High compressive and flexural strengths • Increased freeze/thaw durability and resistance to deicing salts • Compatible with coefficient of thermal expansion of concrete - Passes ASTM C 884 • Increased density - improved carbon dioxide resistance (carbonation) without adversely affecting water vapor transmission (not a vapor barrier)
• Application thickness: Minimum 1/8 inch (3 mm). Maximum in one lift - 1.5 in. (38 mm) • Minimum ambient and surface temperatures 45°F (7°C) and rising at time of application • Do not use solvent-based curing compound
SikaTop® 123 PLUS must be scrubbed into the substrate, filling all pores and voids. Force material against edge of repair, working toward center. After filling repair, consolidate, then screed. Material may be applied in multiple lifts. The thickness of each lift, not to be less than 1/8 inch minimum or more than 1.5 inches maximum. Where multiple lifts are required score top surface of each lift to produce a roughened surface for next lift. Allow preceding lift to reach initial set, 30 minutes minimum, before applying fresh material. Saturate surface of the lift with clean water. Scrub fresh mortar into preceding lift. Allow mortar or concrete to set to desired stiffness, then finish with wood or sponge float for a smooth surface.
