Best Practices for 3M Scotch-Weld Control Joint Sealant DP-5106
-
Surface Preparation
For existing control joints, removing all loose aggregate, dust, old caulks, grease or other compounds from the control joint saw cut.
-
Application
Section 1: Preparation: General Preparation of the Control Joint Channel:For new control joints, prepare control joint cavities by making saw cuts 1/4-inch wide by 1/2-inch deep using an abrasive-resistant saw cut blade. Usually the placement of channels for these joints is described by the contractor. Typically control joint channels span 12 to 20 feet square areas.
-
Mixing
With the squeeze of the trigger, the components are automatically mixed and easily dispensed as bubble-free, self-leveling liquids.
-
Clean-Up
Remove the masking tape surrounding the control joint channels.
If desired, grind the cured product with 36 to 50 grit sanding disks or sandpaper to take off any rough edges and achieve the desire shape. Sand with finer grit sandpaper to the desired finish.
