Best Practices for 3M DP600 Gray Non-sag

*See Terms of Use Below
1. Surface Preparation
  
  Remove all loose aggregate, dust, old caulks, grease and waterproofing compounds from repair surface. (Grind away any absorbed oils to ensure a clean surface.)
  
  Clean repair surface with a bristle brush and use moisture and oil-free compressed air to blow out debris
2. Application
  
  Prepare the Cartridge for Dispensing: Select the desired dispenser (manual or pneumatic) and the desired mix tip.
  
  Cut the blind-end off of the cartridge orifice and place the cartridge in the dispenser.
  
  Dispense just enough material so that both components dispense equally.
  
  Assemble the mix tip onto the cartridge with a half-twist.
  
  Prepare the Concrete for the Vertical Repair and/or Custom Tap: Remove all loose aggregate, dust, old caulks, grease and waterproofing compounds from repair surface. (Grind away any absorbed oils to ensure a clean surface.)
  
  Clean repair surface with a bristle brush and use moisture and oil-free compressed air to blow out debris.
  
  Mask off area surrounding repair
  
  General Concrete Repair: Use a spreader to cover the repair and leave an excess of at least 1" around the repair edges.
  
  Keep the end of the mix tip immersed in the product as the repair is being filled.
  
  Place the spreader over the filled repair.
  
  Press down and hold for about 30 seconds to spread the repair compound
  
  Let repair cure before removing the spreader
  
  Note: At 75°F (24°C), a 1/4" thick bead sets in 50 seconds and becomes tack-free in 4 minutes. Thinner masses take longer to cure. Subsequent applications can be made on the initial repair to build thickness
  
  Repairing Concrete Damage from Corrosion: Apply a pre-coat of cement corrosion inhibitor or protectant to excessively corroded areas: Allow pre-coat to dry thoroughly.
  
  Follow the procedure for general concrete repairs.
  
  Repairing Leading Edges on Steps and Stairways: For sharp edges: Follow the procedure for general concrete repairs and shape edge by using two spreaders. Use one spreader to flatten the vertical edge of repair and the other spreader for the top of repair.
  
  For round edges: Form round edges with a piece of 3M™ Plastic Contouring Sheet 4904 on small repairs (less than 3" x 3"). Plastic must be at least 1" larger around than the edges of the repair.
  
  Preparation For Custom-tapping: Drill holes into the concrete, wood or masonry to the specified depth using the chart below.
  
  Use a round bristle brush to clean the cored holes if they have not been freshly drilled.
  
  Use moisture-free and oil-free compressed air to blow out the debris.
  
  Lightly coat the bolts or screws with 3M 5-Way Penetrant
  
  Dispense 3M™ Concrete Repair DP-600 into the hole nearly halfway full. To obtain a consistent fill, judge for under-fill or overfill by counting the number of squeezes of the trigger.
  
  Insert the bolt or screw within the first 20 seconds after dispensing. The paste characteristic of 3M concrete repair DP-600 will hold the bolt or screw in place until it cures. Once the work life has been exceeded, do not disturb the bolt.
  
  Move to the next hole to keep 3M concrete repair DP-600 flowing in the mixer tip. If material sets in the mixer tip, replace the tip and start dispensing again.
  
  Procedures for Custom Tapping Hollow Concrete Blocks, Wood or Masonry: Use 3M™ Reinforcement Patch 4903 to create a mesh net around the bolt. Leave at least a 1" excess of mesh abound the diameter of the bolt. Push the bolt and mesh through the hole
  
  Remove the bolt and then fill the net 3/4-full with 3M concrete repair DP-600 while slowly backing the nozzle out of the hole.
  
  Place the bolt in the hole and complete the fill, if necessary, to adjust for any under-fill.
  
  Allow 3M concrete repair DP-600 to fully cure before removing the bolt and reinstalling it along with the supported load.
3. Mixing
  
  It is packaged as 1:1 ratio liquids in a duo-pak cartridge. With the squeeze of the trigger, the components are automatically mixed through a mixing tip and easily dispensed as a bubble-free non-sag paste.
4. Curing
  
  3M concrete repair DP-600 will become tack-free within 4 minutes and cure within one hour. Note: It is best to wait for one full hour before extracting the bolt or screw for securing the cupboards, wall hangers or other cabinetry in place
  
  Allow 3M concrete repair DP-600 to fully cure before applying a load. The maximum torque recommended is 9.5 pounds
5. Clean-Up
  
  Repair Clean-up and Finishing: 1. Remove masking tape from repair.
  
  2. Shave or grind cured product with 36 grit sandpaper to achieve desired shape.
  
  3. Sand with 80 grit sandpaper to remove any scratches
  
  4. If 3M™ Concrete Repair DP-600 is applied in a traffic area, apply sand or some type of grip to repaired surface area.
