Steps To Polish Concrete

Step 1

Determine Concrete Hardness using a MOHS Test Kit

You will need to determine concrete hardness with a MOHS Concrete Hardness Testerin order to select the correct metal bond diamond abrasives. Start with the highest number tip(9) and continue to scratch the surface with the descending tips until the tip stops scratching the floor. When the tip no longer scratches the floor, you have reached the hardness level of the concrete.  Test at least 3 areas of the floor to get average test rating. Use the Machine Specific Tooling Guideto select the correct tooling bond.

Step 2

Concrete Surface Preparation – Metal Grinding

If the floor is coated, determine type of coating and remove withappropriate tooling. Repair and fill any surface holes or cracks. Grind with either 16, 30/40, 70/80 grit metal bond tooling to achieve desired exposure and floor flatness.TIP:Start with highest grit where possible and move to lower grit when necessary.

Step 3

Transitional Stage - Removing Metal Tooling Marks

Remove metal tooling scratches using 50, 100 or 200 grit transitional tooling. Transitional tooling effectively removes scratches and creates a surface ready for polishing.TIP: Your floor should be free of all visible tooling marks after this stag

Step 4

Densify and Harden the Concrete

Ensure your floor has been vacuumed and all tool marks have been removed. Use eitherULTRAHard LithiumorULTRADensifil(Pore & Crack Filler) densifiers to the concrete to help solidify and densify the surface and to provide extra protection from water penetration and staining. To learn more, see our densifiers page.TIP:  DO NOT let densifiers pool or puddle on your floor.  This can create staining that is difficult to remove in the polishing stages.

Step 5

Concrete Polishing

Begin with appropriate resin bond tooling 200, 400, 800, 1500, 3000 grit (3000 grit optional).  Ensure dust is removed(vacuumed) in between passes. Burnish floor with 3000 grit burnishing pad after your final grit level.

Step 6

How to Seal and Protect Polished Concrete

Once you get the look and polish you’re striving for, you may want to protect the surface by applying a commercial stain-guard product, like WerkMasterULTRAguard sealer and surface wear protectorespecially if the surface will be exposed to grease, oil, or chemicals. Use a pump up Sprayer and apply Two thin light coats. Allow coats to dry for at 30 minutes between coats. Burnish floor to achieve maximum shine and polish with either your WerkMaster Machine or Propane Burnisher.TIP: Start with a low RPM burnishing pass to ensure sealer has cured and pad is not scratching floor
