Mixing Cementitous Material with TX3

For this demonstration we utilized Light Gray DecoPour. Any cementitous material will work. We have experimented with Portland cement, Rapid Set Tru and many others. The cementitous material serves two purposes. First off it gives the material its base color, and secondly it great increases the ability of the material to absorb stain.

Prep the spalled area with a grinder, roto hammer or chisel, then vacuum thoroughly to en-sure that it is free of lose concrete and other debris.


The ratio for this repair material is 1:1:1:1. Be sure the “B” side material is properly mixed and blended, even if it is un-tinted. Measure equal parts by volume of TX3 “A” side, un-tinted TX3 “B” side, sand and DecoPour. Pour the “A” and “B” side into a larger container and mix for at least 20 seconds.


While continuing to mix the material, add in the DecoPour. Once the DecoPour is mixed in completely, add in the sand. Continue to mix until completely blended and no clumps of sand or DecoPour are visible. The sand used in the mixture must be dry. Grit can be varied as need-ed to match the floor. Tinted TX3 can be used if a different color is desired. This repair was completed using un-tinted TX3, Light Gray DecoPour and a mix of 12, 20 and 30 grit sand.


Pour the material evenly across the repair until it is slightly overfilled. The material is self-leveling, but a plastic trowel can be used to move material around as needed.


After completely filling the repair area, broadcast sand on top of the repair. This will ensure a more natural look. Again, the grit of the sand can be varied to match the surrounding floor. Depending on conditions, the repair should be set in about 45 minutes. Grind the repair flush with the floor using a Zec wheel, sand flap disc or equivalent.


The resultant repair is now ready for foot and heavy traffic. It is free of pinholes, will not crack and can be left as is, or stained, densified and polished.
