MIXING
- Wet down all tools and mixer to be used.
- Pour 6 pints (2.8 L) of clean potable water [approximately 70° F (23° C)] into a suitably sized and clean mixing container, using a calibrated measuring jug or similar, to ensure strict control of the water content.
- Add 1 pail while continuing to mix with a low-speed drill (400-600 rpm) and mortar mixing paddle or in an appropriate mortar mixer.
- Once all the powder has been added, mix to a uniform consistency, maximum 3 minutes, until a lump-free blend is achieved.
- Add up to an additional 1/2 pint (0.24 L) maximum of liquid to achieve desired consistency. Do not over-water.
- Thorough mixing and proper proportioning of the powder and liquid is necessary.
- Inaccurate proportioning of the powder to liquid will result in a finished product that may not conform to the typical published performance property values.
APPLICATION
- A neat mix of SikaQuick®-800 mortar must be scrubbed into the mechanically prepared, SSD substrate. Be sure to work into all pores and voids.
- Force material against edge of repair, working toward center. After filling repair area, screed off excess.
- Allow material to set to desired stiffness, then finish with wood or sponge float for a smooth finish, or broom or burlap-drag for a rough finish.
- If a smoother finish is desired, a magnesium float should be used.
- Mixing, placing, and finishing should not exceed 15 minutes maximum.
- Refer to ACI 305 the "Guide to Hot Weather Concreting" or ACI 306 the "Guide to Cold Weather Concreting" when there is a need to place this product while either hot or cold temperatures prevail. Thinner placements will be more sensitive to the temperature conditions.
CURING TREATMENT
- As per ACI recommendations for Portland cement concrete, curing is required.
- Moist cure with wet burlap and polyethylene, a fine mist of water or Sika® Antisol®-250W*.
- Curing compounds adversely affect the adhesion of following lifts of mortar, leveling mortar or protective coatings.
- Moist curing should commence immediately after finishing. Protect freshly applied mortar from direct sunlight, wind, rain, and frost.
*pretest of curing compound is recommended
