`
`How to Use
`Surface Preparation Concrete/Mortar: Remove all deteriorated concrete, dirt, oil, grease, and all bond-inhibiting materials
`from surface. Be sure repair area is not less than 1/8 inch in depth. Preparation work should be done
`by high pressure water blast, scabbler, or other appropriate mechanical means to obtain an exposed
`aggregate surface with a minimum surface profile of ±1/16 in. (CSP-5) Saturate surface with clean
`water. Substrate should be saturated surface dry (SSD) with no standing water during application.
`Reinforcing Steel: Steel reinforcement should be thoroughly prepared by mechanical cleaning to remove all
`traces of rust. Where corrosion has occurred due to the presence of chlorides, the steel should be high-
`pressure washed with clean water after mechanical cleaning. For priming of reinforcing steel use Sika
`Armatec 110 EpoCem (consult Technical Data Sheet).
`Concrete Substrate: Prime the prepared substrate with a brush or sprayed applied coat of Sika Armatec 110
`EpoCem (consult Technical Data Sheet). Alternately, a scrub coat of Sika Top 123 can be applied prior to
`placement of the mortar. The repair mortar has to be applied into the wet scrub coat before it dries.
`Pour Component ‘A’ into mixing container. Add Component ‘B’ while mixing continuously. Mix mechanically
`with a low-speed drill (400 - 600 rpm) and mixing paddle or mortar mixer. Mix to a uniform consistency,
`maximum 3 minutes. Manual mixing can be tolerated only for less than a full unit. Thorough mixing and proper
`proportioning of the two components is necessary.
`Application & Finish 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 final 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.
`As per ACI recommendations for portland cement concrete, curing is required. Moist cure with wet burlap and
`polyethylene, a fine mist of water or a water based*, compatible curing compound. Curing compounds
`adversely affect the adhesion of following lifts of mortar, leveling mortar or protective coatings. Moist curing
`should commence immediately after finishing. If necessary protect newly applied material from direct sunlight,
`wind, rain and frost.
`*Pretesting of curing compound is recommended.
`n Application thickness: Minimum 1/8 inch (3 mm). Maximum in one lift - 1.5 in. (38 mm).
`n Minimum ambient and surface temperatures 45°F (7°C) and rising at time of application.
`n Do not use solvent-based curing compound.
`n Size, shape and depth of repair must be carefully considered and consistent with practices recommended
`by ACI. For additional information, contact Technical Service.
`n For additional information on substrate preparation, refer to ICRI Guideline No. 03732 Coatings, and
`Polymer Overlays".
`n If aggressive means of substrate preparation is employed, substrate strength should be tested in
`accordance with ACI 503 Appendix A prior to the repair application.
`n As with all cement based materials, avoid contact with aluminum to prevent adverse chemical
`reaction and possible product failure. Insulate potential areas of contact by coating aluminum bars,
`rails, posts etc. with an appropriate epoxy such as Sikadur Hi-Mod 32.
`Component ‘A’ - Irritant - May cause skin/eye/respiratory irritation. Avoid breathing vapors. Use with
`adequate ventilation. Avoid skin and eye contact. Safety goggles and rubber gloves are recommended.
`Component ‘B’ - Irritant; suspect carcinogen - Contains portland cement and sand (crystalline silica). Skin
`and eye irritant. Avoid contact. Dust may cause respiratory tract irritation. Avoid breathing dust. Use only with
`adequate ventilation. May cause delayed lung injury (silicosis). IARC lists crystalline silica as having sufficient
`evidence of carcinogenicity in laboratory animals and limited evidence of carcinogenicity in humans. NTP
`also lists crystalline silica as a suspect carcinogen. Use of safety goggles and chemical resistant gloves is
`recommended. If PELs are exceeded, an appropriate, NIOSH approved respirator is required. Remove
`contaminated clothing.
`In case of skin contact, wash thoroughly with soap and water. For eye contact, flush immediately with plenty
`of water for at least 15 minutes, and contact a physician. For respiratory problems, remove person to fresh air.
`In case of spillage, scoop or vacuum into appropriate container, and dispose of in accordance with current,
`applicable local, state and federal regulations. Keep container tightly closed and in an upright position to
`prevent spillage and leakage.
`Mixed components: Uncured material can be removed with water. Cured material can only be removed
`mechanically.
