MS-PATCH is a fast setting cement-based patching compound that requires only potable water for mixing.  It achieves initial set within 8 to 12 minutes and final set in 20 minutes.  After initial set, MS-Patch may be shaved to conform to the shape of the surface to which it is applied.  MS-Patch will provide excellent flexural and bond strengths.  MS-Patch is available in setting times of 5 to 10 minutes.


MS-Patch may be used for patching on overhead surfaces, horizontal and vertical surfaces, above or below grade without forming.  It is used for repair and restoration of precast concrete panels, concrete pipe, castings, beams, curbs, concrete walls, bridges, driveways and sidewalks.


MS-Patch is a specially blended formulation of Portland cements, fine aggregates and select chemical additives.

Surface Preparation

Substrates must be free of loose or deteriorated concrete, dirt and other substrates, which might interfere with proper application.


Concrete or masonry surfaces should be predampened to insure proper bond.  MS-Patch will require approximately 5 quarts of water per 50 lb bag or pail. It is mixed by adding the dry mixture to the proper amount of clean water as indicated.  A rotary mixer is preferable for mixing large amounts of material.  Mix no more than can be placed in 10 minutes.  Do not mix for more than one minute.  MS-Patch should be mixed to a stiff, no slump, putty-like consistency. Do not retemper.  Once mixed, slightly overfill the area to be patched.  After initial set, the patch may be shaved to conform tot the shape of the applied surface.  Use standard curing practices to cure the patch.
