Examine substrates and conditions under which materials will be installed. Do not proceed with Installation until unsatisfactory conditions are corrected. B. Coordinate installation with adjacent work to ensure proper sequence of construction. Protect adjacent areas landscaping from contact due to mixing and handling of materials. 3.20 SURFACE PREPARATION: Comply with manufacturers printed instructions and the following: A. Clean surface to receive grout of all materials including dust, oil, dirt, and grease or Efflorescence. B. Dampen with clean water before patching and remove standing water. 3.30 FORMS: Comply with manufacturers printed instructions and the following: A. Forms must be water tight, strong, properly braced, and properly coated. B. Allow a minimum clearance of 2 inches (50 mm) between forms and baseplate for grout entry. C. Allow a minimum grout head of 6 inches (150 mm). D. Slope form on placing side to assist in grout movement and to prevent trapping air. E. Allow 1 inch (25mm) horizontal clearance and 1 inch (25 mm) vertical clearance for height above bottom of baseplate. F. Provide venting of forms to avoid entrapment of air. 3.40 MIXING: Comply with manufacturers printed instructions and the following: A. Material should be mechanically mixed for a minimum of 5 minutes using a five gallon (19L) bucket with a 3 (12mm) drill and paddle mixer. For large grouting applications a standard mortar mixer should be used. B. Add approximately 1 gallon + 3 pints (5.2L) of clean water for each 50lb (22.7 kg) bag to achieve a fluid consistency. For a Flowable consistency add about 1 Gallon + 1 Pint (4.3L). For a plastic approximately 1 Gallon (3.8L) is needed. Add the powder to the water and mix to a stiff gel-like consistency. Add water sparingly to reach the desired consistency. Do not exceed a flow of 20 seconds per ASTM C 939. Do not mix more material that can be placed in 15 minutes. C. Do not re-temper with additional water. 3.40 APPLICATION: Comply with manufacturers printed instructions and the following: 1. The area to be grouted should be thoroughly flushed and soaked with clean water prior to grouting. Leave no standing water. 2. Place the grout quickly and continuously use light rodding or strapping to eliminate air bubbles. 3. Grout temperature should be maintained from 50F to 90F (10C - 32C) to achieve specified results. Use cold water in hot weather or hot water in cold weather to achieve desired grout temperature. Do not use if temperature is expected to go below 32F (0C) within a 12 hour period. 3.50 CURING A. A damp cure of at least 3 days is necessary to control the Non-Shrink characteristics and maintain strength levels. 3.60 CLEANING A. Remove excess material before material cures. If material has cured, remove using mechanical methods that will not damage substrate.
