Diamond Polishing Discs

Diamond resin polishing discs are a flexible pads for polishing all natural stones, but also ceramic, concrete and engineered stones. They are long lasting and fast working.

Maximum speed for our 100mm and 125mm diamond polishing pads is 4500 RPM (recommended speed 2500 - 4500RPM), which is a lot less than most standard angle grinders (they can be up to 11,000 RPM). The best control is achieved when using a specific polisher, but a variable speed angle grinder (usually 3000 to 11000 RPM), which cost around $300, can be good too. Some customers have had success with orbital sanders with variable speed.
We can not be responsible for any quality issues if you use high speeds with any of our pads (because they will wear out very fast when used at high speed).

Always work flat, with a little pressure. Too much pressure can shorten the disc's working life.

Dry Polishing discs:

Designed to be used dry, which in most situations is a lot easier as water makes a messy slurry that can be difficult to clean up.  They can be used with a tiny amount of water, although this will shorten the life of the pad. 
These velcro backed polishing pads simply stick to the velcro backing pad (available seperately, below)  that attaches to your polisher.

Note - Worksafe WA specify "Uncontrolled dry cutting (ie dry cutting without on-tool dust extraction) is non-compliant and WorkSafe inspectors will take enforcement action where this practice is identified." See more here

Notes on polishing concrete counter tops:

Grinding and polishing results will vary according to the material, machine and operator.

If dry polishing, protect yourself from silica dust with a vacuum. Remove the dust regularly, otherwise it can scratch the surface.
If wet polishing, make sure you are protected from electrocution with a RCD. The water will remove the dust, so scratching is less likely.

The more aggressive, coarser grits work best at exposing aggregates and removing blemishes. 
The finer grits are for final polishing. Progress to higher grit levels until you achieve the desired surface sheen and smoothness.

If you are polish only, you will get a smooth, matt surface (honed).
To get a high gloss finish, a densifier from Crommelins Chemicals or Parchem is required. These are for interior use (will loose gloss finish outside). The densifier will harden the surface, increase abrasion and water resistance and reduce dusting. 
See manufacturer's instructions online. 

Decide on the finish you want:
Uniform Finish – The concrete is a uniform colour because there is still a thin layer of cement over the surface.
Light Polish – The thin layer of cement is removed, so a fine sand aggregate is exposed. 
Ground Finish – As you polish deeper into the concrete, you begin to expose the larger aggregate (stones) that is in the concrete mix.

Clean the fully cured (minimum 10 days) concrete countertop to remove any grit that could gouge the concrete as you grind.
Patch any minor flaws or holes with a patching slurry prior to polishing. Mix up the slurry using a combination of cement, fine sand, water, and pigment.
Remove any dags or high points with one of our turbo cup wheels, with water.
Start by polishing with the coarsest pad (#50 grit), depending on the desired finish. Go over the entire surface.
Hold the polisher as flat as possible on the surface and apply even pressure to prevent swirl marks.
Use hand pads of same grit to polish areas the polisher can't reach. See our range here.

Change to a #100 grit pad and polish the entire surface again. Repeat this process, working progressively through all the grits till the desired shine is achieved.
Clean, then let the surface dry. If applying sealer, follow the manufacturers instructions. Some sealers require the surface to be polished only to #800 grit so that it can bond to the surface, so don't over polish.
