MS-Plug is a cement-based hydraulic cement that is fast setting.  It is used to instantly stop running water or seepage leaks in concrete or masonry.  When mixed with clean potable water, STANDARD MIX sets in 3 to 5 minutes; HOT MIX in 45 to 90 seconds.  Actual setting time depends on the temperatures of the dry powder, mixing water, and the structure to be patched.  Cold temperatures will retard the setting time.  Hot temperatures will accelerate it. Mixing water should be around 21 degrees Celsius.  MS-Plug expands as it sets.

Uses

MS-Plug is used above or below grade, interior or exterior, to stop water seepage and flowing water in concrete and masonry.  MS-Plug is an ideal patching material for manholes, sewers, concrete pipe, wells, retaining walls, water treatment plants, tunnels and basements.

Composition/Materials

MS-Plug is a blend of Portland cement, fine aggregates, and other ingredients modified to control initial and final set times.

Surface Preparation

All surfaces must be clean and free of dirt, dust, paint, and sealers that will inhibit the patching material from bonding.  Dampen areas to be patched before applying MS-Plug.  DO NOT retemper.  MS-Plug is recommended for use when the temperature is 40 degrees F and falling.

Mixing Instructions

Pour water into a mixing container (1 pint of water will mix approximately 8 lbs of powder).  Add the dry powder, mixing rapidly with a trowel to a stiff, no slump consistency.  Mix no more than 30 seconds.  Do not add aggregate or additives to the mix.

Application Techniques

Dampen surface to be patched with water prior to application of Ms-Plug.  Form the patch in the shape of a cone and force it into the cracks or holes where water is seeping.  Keep pressure on the patch until it achieves its initial set.  MS-Plug may be shaved to conform to surrounding surfaces.

Coverage

One pound will fill 17 cubic inches or a crack 3/4" x 3/4"x 30".
