0.0 (0)
SikaQuick® EZ Patch is a cementitious, one-component, fast setting material used for concrete surface repairs .
- Easy to use, one-component
- Variable water ratios to achieve different product consistency
- Interior and exterior use
- Feather edge application
- High compressive and flexural strengths
- High abrasion resistance
Usage
- Used to reprofile substrates or subfloor surfaces from feather edge to a maximum 1-1/2” (38 mm) in thickness.
- Repair minor defects, holes, cracks and pre-fill static (i.e. nonmoving) joints and seams in concrete, balconies, terraces, etc.
- On grade, above grade and below grade on concrete and mortar.
- On horizontal surfaces.
- For pedestrian traffic only.

Temperature will affect the Application Life:
-
Above 73° F (23° C) will reduce the application life and workability
-
Below 73° F (23° C) will extend the application life and workability

Coverage
12-15 ft2 at 1/4" (1.1-1.4 m2 at 6 mm) per bag
(Coverage range does not include allowance for surface profile, surface porosity or material waste.)
MIXING
- As with all prebagged cement products, some settlement may have occurred during transportation and storage. Dry blending of the material is recommended.
- Pour 4.5 - 5.5 pints (2.1 - 2.6 liters) of clean, potable water [approximately 70° F (21° 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 SikaQuick® EZ Patch to the water while slowly mixing, adding the entire contents of the bag.
- Mix with a low-speed drill (400-600 rpm) and a mud paddle to blend water and powder for approximately 2 to 3 minutes. Mix until a lump-free, uniform mix has been achieved.
- Avoid entrapment of air due to excessive mixing as this will impact performance. Do not mix more mortar than can be used within the stated application life, taking into consideration ambient and substrate temperatures.
- Refer to ACI 305R "Guide to Hot Weather Concreting" and ACI 306R "Guide to Cold Weather Concreting" for guidelines when there is a need to place this product in hot or cold temperature conditions. Thinner installations will be more sensitive to ambient and substrate temperature conditions.
EXTENSION WITH AGGREGATES
- For applications greater than 1-1/2" (38 mm) in depth, add 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 handling and physical properties of SikaQuick® EZ Patch, resulting in different cured performance values.
- Do not use limestone aggregate.
- The addition rate is 9 lbs (4.1 kgs) of aggregate per bag. This addition rate is approximately 0.72 gallons (2.7 liters) by loose volume of aggregate.
- Do not use additional water. Maximum 5.5 pints (2.1 liters) of clean water per mix.
APPLICATION
- SikaQuick® EZ Patch must be initially scrubbed into the mechanically prepared, SSD substrate, filling all pores and voids.
- Force material against edges of repair, working toward center.
- After filling the repair area, consolidate, then screed.
- Allow product to set to desired stiffness, then finish with a wood float or a sponge float for a smooth surface, or broom for a rough finish.
CURING TREATMENT
- SikaQuick® EZ Patch must be protected against contamination and from precipitation.
- Moist curing method is not required. Allow to air cure.
