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. Remove all spalled and unsound concrete from area to be repaired. If rusty reinforcing steel is present; it must be abrasive blasted to remove rust. B. Remove enough material to completely expose reinforcing steel. C. Large vertical or overhead patches deeper than 2 (50 mm) should contain reinforcing steel. Additional steel should be inserted using appropriate techniques, if none is present. D. Clean surface to be repaired of all materials including dust, oil, dirt and grease. E. Dampen with clean water before patching and remove standing water. 3.30 MIXING: Comply with manufacturers printed instructions and the following: A. Material should be mechanically mixed for approximately 3 minutes using a five gallon (19L) bucket with a 3 (12 mm) drill and paddle mixer. For large repairs a standard mortar mixer should be used. B. Add 1 gallon + 3 pints (5.2L) of clean water for each 60lb (27.2 Kg) bag. Add the powder to the water and mix to a stiff gel-like consistency. If mix is too firm, add water sparingly to reach the desired consistency. Do not mix more material than can be placed in 15 minutes. C. For repair deeper than 2 (51 mm), up to 30 lbs (13.6 Kg) of clean, high qualit"8:NT   2 6 ~ ļvh]hUJh8h8CJaJh8CJaJhZQ5CJ\aJh h85CJ\aJh7h8CJaJh>AhB!h8h8h+g5CJ \aJ h+g5CJ \aJ h8h85CJ \aJ h7CJaJh+gCJaJh+gh+g5CJ\aJh+gh85CJ\aJh7CJaJh+gCJaJh8CJaJhhJj:  p q  h0]0^gd8 h0]0^gdgd 0]0^gd8 $0]0a$gdZQ0]0gdB!0]0gd70]0gd+g0]0gd8vE  ( n q ^ k l m ̾߶߮߮߮߮ߐ߈ߐ߀xph CJaJhTCJaJh+gCJaJhB!CJaJh2#+CJaJh2#+h2#+5CJ\aJh-hCJaJhZQCJaJheZfCJaJh+gh85CJ\aJh+gh8CJaJhgdCJaJh8CJaJh2#+h85CJ\aJh8h8CJaJ, * \ S    h0]0^gd  h0]0^gdgd h0]0^gd2#+ h0]0^gd8 h0]0^gd-h h0]0^gdeZf     ' ( - . 2 3 ; = > K L S T ] ^ j k x y B4\квЪкТВh.CJaJh4"CJaJh~I4CJaJh7cCJaJh:`CJaJh+gCJaJh\CJaJh2#+hT5CJ\aJhCJaJhTCJaJh CJaJh2#+CJaJhgdCJaJh8CJaJhB!CJaJ3 ; < 360]0gdZQ h0]0^gd:` h0]0^gdgd h0]0^gd8 h0]0^gd RSetur$tvOP~ h0]0^gd h0]0^gd. h0]0^gd{5 h0]0^gdgd h0]0^gd8\dgijt24~%/V]bo   (25FGHIKLQRVW^j}  º²²ªªª¢ª¢šššššª¢ª¢¢ºh CJaJh-CJaJhCJaJhCJaJhZQCJaJh~I4CJaJh5CJaJh+gCJaJh{5CJaJhgdCJaJh.CJaJh2#+h.5CJ\aJ<!>?"#67HIO h0]0^gdgd h0]0^gd  h0]0^gd. h0]0^gd ,79;<GHhnw[]gY]`̼⮠Ԙ̼̼̐̈̈xxxxha YCJaJh*CJaJh{5CJaJh+gCJaJhECJaJh2#+h2#+5CJ\aJh2#+h-5CJ\aJhCJaJh6CJaJh-CJaJh2#+hgd5CJ\aJhgdCJaJh2#+h~I45CJ\aJh~I4CJaJ.  hNXYj h0]0^gd{5 h0]0^gd* h0]0^gdgd h0]0^gd2#+ h0]0^gd8`afijkm26~#'1:D <<<<Z<<<<ƾξξΞUhI&CJaJh|CJaJh{5CJaJhU`CCJaJh CJaJh5CJaJhCJaJha YCJaJhECJaJhgdCJaJh2#+hgd5CJ\aJh2#+h2#+5CJ\aJh2#+ha Y5CJ\aJ4jk*<<<(=*= h0]0^gdU`C h0]0^gd| h0]0^gd  h0]0^gd+g h0]0^gd8 h0]0^gdgdy 3 (12 mm) gravel may be added to the mix per 60-lb (27.2 Kg) bag. D. Do not re-temper with additional water. 3.40 APPLICATION: Comply with manufacturer s printed instructions and the following: A. Material should be trowel applied to a damp surface. B. Apply a thin layer with heavy trowel pressure and then build up to the desired thickness. Material obtains high bond strength without the use of bonding adhesives or acrylic additives. C. After initial set, the material may be trimmed and shaped to match the contours of existing patch area. D. Do not apply if temperatures are below 40F (4C) or are expected to go below 32 (0C) within a 24 hour period. Use cold water in hot weather or hot water in cold weather to achieve desired grout temperature. 3.50 CURING A. No special procedures are required. During the first 24 hours, keep the patch covered or damp to prevent excessive loss of water. 3.60 CLEANING A. Remove excess material before material cures. If material has cured, remove using mechanical methods that will not damage substrate.
