DIRECTIONS FOR MIXING:
Pour U-MIX® Sand Mix into a clean wheelbarrow, mortar box, or mixing bucket. Form a crater in the center of the dry mix. Pour clean potable water into the crater at a rate of one quart per 15 pounds of mix. Work the mix with a shovel or hoe adding water as needed to achieve a stiff moldable mixture. Avoid over wetting the mix. Adding excessive water may weaken the mix.
FOR BEST RESULTS:
Use only when temperature is 40° and rising. In cold weather use warm, not hot, water for mixing.
Apply freshly mixed U-MIX® Sand Mix immediately. Do not retemper the mix after initial mixing.
When patching or resurfacing, it is important to dampen the surface of the existing concrete before applying the new material. The use of quality bonding agents in recommended.
Allow the new concrete to set firmly, then keep moist for at least three (3) days by applying an occasional fine spray with water. Covering the surface with plastic film or damp burlap is also beneficial.
