Application

Application Information

5 - 5.5 pints (2.4 - 2.6 L)

65^° - 75^° F (18^° - 24^° C)

> 45^° F (7^° C)

20^° - 45^° F (-7^° - 7^° C) with the use of SikaQuick® Winter Boost

> 45^° F (7^°C)

20^° - 45^° F (-7^° - 7^° C) on a frost-free surface with the use of SikaQuick® Winter Boost

Approximately 15 minutes

Product temperature will affect the Application Time:

• Above 73° F (23° C) will reduce the Application Time and workability

• Below 73° F (23° C) will extend the Application Time and workability

Application Steps

• Wet down all tools and mixer to be used.
• Pour the required amount of clean potable water [approximately 70^o F (23^o C)] into a suitably sized and clean mixing container, using a calibrated measuring jug or similar, to ensure strict control of the water content. Do not over-water.
• Add 1 bag 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.
• 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.

• With water or undiluted SikaLatex® R: Pour 5 pints (2.4 L) of liquid into the mixing container. Slowly add powder, mix and adjust as above. Add up to an additional 1/2 pint (0.24 L) maximum of liquid to achieve desired consistency. Do not over-water.

• With diluted SikaLatex® R: SikaLatex® R admixture may be diluted up to 5:1 (water: SikaLatex® R) for projects requiring minimal polymer modification. Pour 5 pints (2.4 L) of the mixture into the mixing container. Slowly add powder, mix and adjust as above.

• With SikaQuick® Winter Boost

• Pour the recommended volume of clean, potable water [> 34° F (1° C)] into a suitably sized and clean mixing container. There should be no ice in the water.

• Add 1/2 or 1 cup per bag into the water and mix until it is dissolved.

• Add the contents of the SikaQuick®-2500 bag while continuing to mix.

• Refer to the current Product Data Sheet for complete and detailed instructions on the use of the SikaQuick® Winter Boost.

EXTENSION WITH AGGREGATES

• For applications greater than 1" (25 mm) in depth, add 3/8" (10 mm) coarse aggregate.
• The typical addition rate is 25 - 30 lb (11.4 -13.6 kg) of aggregate per bag. This is approximately 2.0 - 2.4 gallons (7.6 - 9.1 L) by loose volume of aggregate.
• Greater application thickness can be achieve with the addition of up to 50 lbs (22.7 kg) of 3/8" (10 mm) coarse aggregate.
• The aggregate must be non-reactive (reference ASTM C 1260, C 227 and C 289), clean, well graded, Saturated Surface Dry (SSD), have low absorption and high density, and comply with ASTM C 33 size number 8 per Table 2.
• Variances in the quality of the aggregate will affect the physical properties of SikaQuick®-2500 and may result in different strengths.
• Do not use limestone aggregate.
• Do not exceed a slump of 7" (178 mm). This may cause excessive bleeding and retardation and may reduce the strength and performance of the material.

• A neat mix of SikaQuick®-2500 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.
• To assist in the finishing process, use SikaFilm^® finishing aid. Consult current Product Data Sheet.
• 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.

• As per ACI recommendations for portland cement concrete, moist curing is required.
• Moist cure with wet burlap and polyethylene, with a fine mist of water or with a water based,* compatible, curing compound meeting ASTM C 309.
• Moist curing should commence immediately after finishing.
• Protect freshly applied mortar from direct sunlight, wind, rain and frost.
• To prevent from freezing, cover with insulating material (e.g. curing blanket).

* Pretesting of curing compound is recommended.
