To Restore Floor from Scratches and Cracks

For Example; Scratches are Deep on Surface. (High Traffic Area)

Recommendation; Hone and Polish for Scratches. Grinding and Polish for Cracks.  Sealing optional.

Overview:

Hone: Scratch removing by wet grinding with diamond pads. (A satin finish with little or no gloss). Must be further processed for a brilliant shine.

General Direction for Grinding Instructions (always use a professional)

To achieve a good result in grinding and polishing marble, Terrazzo, Limestone, Travertine etc.

A 15" to 20" floor machine should be used.

The grinding should begin near the walls, proceeding then gradually towards the center.

The machine must work Parallel to the wall. This way the borders can be level much easily, and the machine can absorb the shocks caused by the roughness of the floor without knocking against the wall.

It is very important that the borders near the wall be leveled carefully, to prevent damaging of finer grits against a lippage in the floor, and to avoid the long and never-quite-perfect work of smoothing them by a hand grinder.

It is very important to choose the right diamond, bond and shape to match the requirements of the work to be done.

The machine must never stand stationary in one spot when the motor is running. Use a medium swinging motion.

Do not grind stone without water (dry). you can burn the stone (If this happens the damage is non - reversible).

Always be sure to apply water before starting the machine. Do not use to much water. In tests for the optimal amount of water verses time, It has been determined that it is better to pour small amount of water on the low grits, and increase the water supply when using higher grits.

When getting to low point (dips) in the floor, it is important to grind with a round movement to level a bigger portion of the floor to hide the wave. The waves will be more noticeable after polish.

When grinding a high lippage floor it is better to grind from the high point towards the low point to protect your diamond and to protect the high corner stone (from chipping or collapsing).

Grinding: 30 to 50 grit *(120 Grit)

Cut (Lippage) to level the surface.

Tools:

-Lippage removal diamond.

-Resin bond diamond.

-Metal bond diamond.

-Classic Carbide stones.

Install the first cutting tools 1/2" from the edge (inside).

(Cutting tools or lippage removal should be tapered at the edge.)

* Use 120 grit cutting tools for very delicate or vain Materials.

When cutting a high lippage, work from the high level to the low (to protect your cutting tools).

Work the machine all the way to the walls.

Water: start the cutting with a very wet past like.

Honing: 120 to 220 grit.

Erase the cutting scratches.

Tools:

-Resin bond diamond.

-Metal bond diamond.

-Classic Carbide stones.

This time we will put the diamond only 1/4" from the edge, to make shore we remove all the cutting scratches.

P.S. It is very important to rinse the surface between every grit, to remove all the last grit remains.

Water: every higher grit add more water.

Polish: 400 to 600-800 grit.

Depending on the materials finish with low (600) grit on hard & high (800) grit on soft.

Tools:

-Resin bond diamond.

-Classic carbide stones.

This time we put the diamond all the way to the edge, to erase all remain honing scratches.
