Yield
Approx. 0.018 m3 (0.65 ft3) of fresh grout per 30 kg (66 lb) bag
MIXING
Mechanical mixing of the King® RPL-20 using a drill mixer or a grout paddle mixer is required. Place 7.75 L (2.05 US gal.) of water in a clean mixer or pail and slowly introduce the entire bag of King® RPL-20. Always mix the entire content of the bag. Only if additional water is required to meet the target flow, slowly add additional water while the mixer is running, not exceeding the maximum recommended water dosage of 8.25 L (2.18 US gal.) per 30 kg (66 lb) bag. Continue mixing for three (3) minutes and stop only when material has reached an homogeneous consistency.
APPLICATION
The application of the grout must comply with the requirements of section 6 and 8 of CSA-A371-14
CLEAN UP
In order to avoid the use of chemicals, it is always recommended to clean grout projections on adjacent surfaces such as sidings, neighboring openings, metal flashings, etc. within the hour following the installation by using only clean water and a nylon brush.
Be sure to clean a test area before proceeding with the work.
Clean all tools and equipment after use with water. Once hardened, the product can only be removed mechanically.
