Cut out all cracked, chipped and deteriorated concrete until a sound surface is obtained. Clear area free of dust, dirt and oily contamination. Rinse area with clean water, leaving a damp, puddle free surface.
Included in the pail. Add water to the primer container until full and shake to mix.
Mixing E-Z Flow Patching Cement
Mix 1 US Gallon (4L) clean water with 50lb. (22.7 kg.) Stone Mason® E-Z Flow Patching Cement. Mix until a smooth, creamy, pourable consistency is achieved. A power mixer is recommended. Let stand for 2 minutes and remix. Add more water if needed to obtain a proper flow. Do not add too much water or over mix. Over watering and over mixing will decrease strength, abrasion resistance and may cause cracking and other surface defects.
Brush or roll-on diluted primer onto the surface to be repaired. Let the primer dry to a tack free surface before applying the E-Z Flow Patching Cement (approx. 20 minutes to 1 hour). Absorbent concrete may require two applications of the primer to prevent development of pinholes, bubbles and loss of adhesion. Place the Stone Mason® E-Z Flow Patching Cement onto primed surface by pouring it out of the mixing pail. Light trowelling may be required to assist flow of product and to obtain proper feather edging. Build up in layers no thicker than 1 inch (2.54cm) at one time but not less the ¼" (0.64cm) with the exception of feather edging. Do not apply a second layer until the previous pour takes foot traffic, under normal conditions, 4 to 6 hours. If more than 24 hours have passed from the first application, re-prime the surface before pouring the next layer.
Another way of patching areas greater than 1" thickness is to add washed pea gravel ¼" (6mm) in size to the Stone Mason® E-Z Flow Patch. Mix Stone Mason® E-Z Flow Patching Cement with water first, then add pea gravel. Use 20lb. (9kg) of pea gravel per 50lbs. (22.7kg) pail. If aggregate is wet, reduce the amount of water to avoid over watering
Apply when temperatures are above 5°C (40°F) and no rain is forecasted for the next 24 hours. Do not apply to frozen surfaces. Do not apply to surfaces that are subjected to hydrostatic pressure. Stone Mason® E-Z Flow Patching Cement will not correct or compensate for problems caused by structural defects.
In hot, windy weather and direct sunlight, the repaired surface should be covered with wet burlap or plastic and kept moist for 24 hours. Stone Mason® E-Z Flow Patching Cement can be open to foot traffic in 4 to 6 hours, light traffic if 24 hours and heavy traffic in 72 hours.
