SikaQuick® Smooth Finish
SikaQuick® Smooth Finish is a fast-setting, one-component, polymer-modified, durable, cementitious mortar for repairing and reprofiling vertical and overhead concrete surfaces to achieve a smooth finish.
- Fast-setting; minimal time required between lifts
- Ultra-smooth consistency; easy to apply
- Fast finishing time, potentially sanded and painted same day or next day
- Polymer-modified
- Time- / labor-saving material; application up to 1/2 inch (13 mm) on vertical surfaces in one layer
- Easy to mix; just add clean water
- High bond strength ensures excellent adhesion
- Suitable for interior and exterior applications
Usage
- Tilt-up panels
- Precast concrete
- Cast-in-place concrete
- Concrete block
- Masonry

Precast gray
Product Details
Shelf Life
12 months from date of production if stored properly in original, unopened and undamaged, sealed packaging
Storage Conditions
Store dry at 40° – 95° F (4° – 35° C)
Protect from moisture. If damp, discard material.
Compressive Strength
1 day | 1,000 psi (6.9 MPa) |
28 days | > 2,000 psi (13.8 MPa) |
Tensile Adhesion Strength
28 days | > 250 psi (1.7 MPa) substrate failure |
Application
Mixing Ratio
8 quarts - 9 quarts (7.6 - 8.5 liters) of clean water per 50 lb (22.7 kg) bag
2:1 per volume (powder : water)
Layer Thickness
Minimum | Maximum in one lift |
Feather edge | 1/2 inch (13 mm) |
If multiple lifts are required, score top surface on each lift to produce a roughened substrate for next lift. Allow preceding lift to develop initial strengths before applying fresh material. Lightly mist with clean water to create a saturated surface dry (SSD) condition.
Product Temperature
65° - 75° F (18° - 24° C)
Ambient Air Temperature
40° – 95° F (4° – 35° C)
Substrate Temperature
40° – 95° F (4° – 35° C)
Pot Life
Approximately 30 minutes
Temperatures will affect the Application Life:
-
Above 73° F (23° C) will reduce the Application Life and workability. Warmer temperatures will increase the rate of strength gain
-
Below 73° F (23° C) will extend the Application Life and workability. Colder temperatures will decrease the rate of strength gain
Finishing time is approximately 1 hour at 73° F (23° C). The product's finishing time will also vary depending on ambient and substrate temperature conditions.
Waiting / Recoat Times
Refer to Sika Tech Brief # 18-01 for minimum cure times prior to overcoating.
Coverage
115 ft2 (10.7 m2) at 1/16 inch (1.6 mm) thickness per bag
(Coverage figures do not include allowance for surface profile and porosity or material waste)
MIXING
- Wet down all tools and mixer to be used.
- Pour 8 quarts (7.6 liters) of clean water into a suitably sized mixing container.
- Add the entire bag's contents of SikaQuick® Smooth Finish to the mixing water while continuously mixing with a low-speed rotary drill (400-600 rpm) and paddle.
- Add up to an additional maximum 1 quart (0.95 liter) if needed for the desired consistency.
- Do not overwater as excess water may result in difficulty handling and/or not meeting stated typical physical performance values.
- Mix to a uniform consistency, maximum 3 minutes.
- Do not re-temper.
- Manual mixing can be tolerated only for less than a full unit. Thorough mixing and proper proportioning of SikaQuick® Smooth Finish and clean water is necessary.
APPLICATION
- SikaQuick® Smooth Finish should be applied in one pass in thicknesses ranging from a true feather edge to 1/2 inch (13 mm) in depth.
- Once material is in place and as material hardens, use a trowel to shave or cut the excess material to the desired shape.
- Depending upon actual ambient and substrate temperatures, SikaQuick® Smooth Finish can potentially be sanded and painted the same day or next day.
- 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
- At 70°F (21°C), SikaQuick® Smooth Finish does not require the use of a curing compound.
- Misting with water should be considered if the product is exposed to higher ambient temperatures, windy or dry conditions.
