Concrete Polishing Steps – No Color

These steps are for a full sand exposure going dry, no dye, to a high satin or high gloss finish.

Step 1: Start grinding 30/40 grit soft or extra soft bond metal diamond. Very important to do a perpendicular pass on the second pass of the 30/40 metals. If not, you can leave lines in the concrete.
**Note** If on soft concrete, you may need a medium or hard bond.
-Sweep dust after machine passes
-Change Grit.
Run the machine between 400-550 RPM

Step 2: Patch holes, cracks, and joints with Rapidset Skim Coat or PRM 16. You want the repairs slightly overfilled but not excessively.

Step 3: Change grit to 60/80 soft or extra soft metal diamond. Very important to do a perpendicular pass on the second pass-Vacuum excess dust lying on the floor.
Run the machine between 400-550 RPM

Step 4: Change diamond to the Boride 50 Grit BSD Ceramics. Do an up and back pass. These are the best diamonds ever made. They last over 10,000-15,000 sq ft and remove metal scratches with ease.
-Vacuum excess dust lying on the floor.
Run the machine between 600-700 RPM

Step 5: Change diamond to the Boride 100 Grit BSD Ceramics. Do an up and back pass.
-Vacuum excess dust lying on the floor.
Run the machine between 600-700 RPM

Step 6: Apply Densifier at a rate of 200 to 400 sq ft per gallon. Pour liberally on the concrete and use a soft broom to work into the slab. Allow the Pantheon Densifier to dry overnight if possible. If not, you can not let it dry overnight then allow it to dwell for 30 minutes or longer.

Step 7: Change diamond to the Boride 400 Grit BSD Ceramics. You do not need to do a 200 grit since the Ceramics refines the concrete so well due to the extremely high diamond content. This has been verified and tested with a RA meter, so if you do a 200 grit, you are not getting any value out of it.
Run the machine between 600-700 RPM.

Step 8: Change to Boride 800 Grit BSD Dry Resins. Do this grit if you want a high gloss finish.
Run the machine between 700-1,000 RPM

Step 9: Apply one coat of stain protection and burnish.

Step 10: Burnish floor (repeat step 9 & 10 if needed).

 

Edges:

  1. L Segment-Do this grit very slow and move it out of the wall and do not do a Straight line, or you will dip the edge. The L Seg will remove the cream and create a wonderful scratch pattern.
    **Note** If the concrete is soft, try going to a 50 Easy Edge first. You may be able to skip the L Seg.
  2. 50 Ultra Edge
  3. 100 Ultra Edge
  4. 400 Resin.
