Frequently Asked Questions

What is the minimum placement thickness for SikaGrout 885 MF? The minimum placement thickness is 1 inch (25 mm). For lifts exceeding 6 inches (152 mm) in depth, consult your Sika representative for specific guidance.

What is the recommended mixing water temperature?
For optimal results, use mixing water between 50-80°F (10-27°C). Adjust water temperature based on ambient conditions to achieve a mixed grout temperature as close to 70°F (21°C) as possible.

How long is the working time and when does the final set occur?
Working time varies by consistency: 3.5 hours for plastic, 5 hours for flowable, and 5.5 hours for fluid consistency. The final set occurs at 4.5, 6, and 8 hours respectively.

What flow characteristics should I target for placement?
For optimal placement, target 25-30 seconds using the ASTM C 939 Flow-Cone Method. Use the minimum water required to achieve necessary placement consistency.

Can SikaGrout 885 MF be used in exterior applications?
Yes, it is freeze/thaw resistant and suitable for exterior applications. Protect from freezing until it reaches 3,000 psi compressive strength.

How much coverage does one bag provide?
One 55 lb bag mixed with approximately 10 lbs (1.2 gallons) of water yields approximately 0.43 ft³ of grout. Water requirements may vary based on mixing conditions.

What surface preparation is required?
Concrete surfaces must be clean, SSD (saturated surface dry), and roughened to CSP 5-10. For dynamic applications, chip surfaces to ±3/8 inch roughness. Steel surfaces must be free of contaminants.

What are the strength development characteristics?
At plastic consistency: 5,000 psi at 1 day, 7,000 psi at 3 days, 9,000 psi at 7 days, and 11,000 psi at 28 days. Fluid consistency achieves slightly lower early strengths but similar ultimate strength.
