THE CONCRETE POLISHING PROCESS

Step 1. Floor Pour

A special Aggregate Concrete floor mix is poured, the mix includes extra stone.

Tips:

  • You can add by hand additional stone during pouring to obtain a more even coverage
  • Coloured or white stones or coloured glass can be added for special effects
  • To achieve the best results IT IS IMPORTANT THAT: -Your concrete contractor or builder is specialist in pouring aggregate concrete floors. Contact John for a list of recommended aggregate floor layers
  • Concrete should be BULL FLOATED (not Kellyfloated). Kellyfloated concrete gives a hard surface layer which is difficult to grind through & to polish.
  • The last top section of the pour should NOT BE VIBRATED (so that the stone remains near the surface)
  • The concrete should be CUT (straight expansion concrete saw cuts) to avoid cracking in preference to using “crack mates” which can result in uneven jagged cracks through the floor. Saw expansion cuts can be filled and then ground to give an even finish whereas “crack mates” cracks are difficult to fill and are uneven.
  • The concrete floor should be left to cure for 12 to 15 days before grinding starts to avoid the process pitting a soft concrete surface.

Step 2. Grinding and polishing

Grinding and polishing the concrete is a four grind process (4 passes over the complete floor) using grinding shoes of different diamond segments.

First course grind                                         Second grind 30 grit, exposes more stone process for polishing concrete 3 process for polishing concrete 4
Third Grid, removes scratches & surface pin holes     -    and the Final polish at 100 grit

Firstly the course grind 25 grit to remove top surface & expose the stone, next is the medium grind 30 to 40 grit taking out major defects and grinding the stone, followed by the third grind of fine 60 to 80 grit to remove scratches & circular scuff marks left from course grinds and the final scratch removal & smooth polish at 100 grit.

Options for sealed finish are high gloss, semi gloss or matt finish.
The gloss level depends on personal taste and final use of the room(s).
Three sealing coats are required for durability.

We can do the sealing for you, or you can easily do it yourself.

If you choose the DIY option, John will put you in contact with a reputable product supplier who will give you professional advice to help you select the most appropriate produce for your purpose with the added bonus of providing you the product at a competitive price!

If you give him the measurements of the floor area to be sealed, he can accurately calculate the amount of product you will need.

We understand DIY is not everyone's wish, and we do provide the full service so just let us know what you'd prefer.

Voila! The finished product – a high gloss – office floor!exposed concrete aggregate floor
