MIXING
Mix mechanically using a heavy-duty, low-speed drill (300 - 450 rpm) with a Mud Mixer/Box or Propeller-type paddle. Shake Component A before using, then pour approximately 85 % of Component A into mixing container. Add Component B while continuing to mix. Mix to a uniform consistency for a maximum of three (3) minutes. Add additional Component A to mix if a wetter consistency is desired. Should smaller quantities be required, be sure that components are dosed in correct ratio and thoroughly premix component B before dosing. Ratio is A:B = 1:7 by weight approximately. For application greater than 38 mm (1½ in) in depth, add up to 17 kg (37.5 lb) of 10 mm (3/8 in) coarse aggregate. The aggregate must be non-reactive (reference ASTM C1260, C227, and C289), clean, well graded, saturated surface dry, have low absorption, high density and comply with ASTM C33, size number 8 per table 2.
APPLICATION
At time of application, surfaces should be damp (saturated surface dry) with no glistening water films. A scrub coat should be applied prior to the placement of the mortar. Apply a 3 mm (1/8 in) thick scrub coat of SikaTop®-122 Plus into the substrate, filling all pores, voids and edges. Alternatively, SikaTop® Armatec-110 EpoCem® can be used as a bonding agent. Apply mortar before bond coat dries, then screed. Force product against edge of repair, working toward center. Allow mortar to reach initial set [50 to 75 minutes after placing at +23 °C (73 °F)], then finish with wood or sponge float. For extra smooth finish, wipe steel trowel with Component A during finishing. If repair requires several lifts, each lift must be applied as soon as the previous lift will support it and all surfaces but the last must be left rough. Unfinished work from previous day must be roughened and any polymer film removed to ensure bond.
CURING TREATMENT
As per ACI 308 recommendations for cement concrete, curing is required. To achieve performance consistent with Technical Data, curing must be provided by recognized curing methods, such as wet burlap covered with white polyethylene film or approved water-based curing compound, such as Sika® Florseal WB-18 & -25. Alternatively, the use of Sika® Ultracure DOTTM or NCFTM wet curing blankets is strongly recommended. Curing must commence immediately after placing and finishing. Moist-curing must be maintained for the first 24 hours only. Protect freshly applied mortar from direct sunlight, wind, rain and frost.
CLEAN UP
Clean all tools and equipment after use with water. Once hardened, the product can only be removed manually or mechanically.
