Polished to 800
The honed floor taken further through resin polishing steps to a satin sheen, with densifier applied between stages.
What you see. A low, even lustre. Light reflects but objects do not mirror. Aggregate reads crisply.
Where it suits. The default for interior living areas. It gives the depth people want from polished concrete without the upkeep of high gloss.
What to know. This is where slab flatness starts to show. Undulations that are invisible at matte become visible as the sheen rises.
The numbers
- Gloss (DOI)
- 40-69
- Grit sequence
- 20-150 metal, grout, resin 50-800, densify, seal, burnish
- Removal depth
- 2-4 mm
- Slab flatness
- FF 35-45
Removal depth depends on the aggregate exposure you choose as much as the finish. Full stone exposure takes 5-6 mm.
Who it is for
- Open-plan living, kitchen and dining
- New builds with a slab poured for polishing
- Renovations over a sound existing slab
Included
- Grinding to your chosen aggregate exposure
- Metal grits to 200, then resin 100, 200, 400 and 800
- Densifier between stages
- Penetrating sealer and burnish
- Edges by hand to within 3-6 mm of walls
Not included
- Removing tiles, carpet, glue or old coatings - quoted separately after we see them
- Structural crack repair or slab levelling
- Moving furniture and appliances
How it runs
- 1
Plans or inspect
From the plans, or on site: flatness, strength, and whether set-downs allow the removal depth.
- 2
Sample area
The first step of the job: a small area finished on your own slab and signed off before we do the rest.
- 3
Grind and polish
Metal grits to the exposure you chose, then resin grits up to 800.
- 4
Seal and burnish
Penetrating sealer, then a burnish to lift the sheen.
Time on site. Usually six to seven days on site for a typical house.
Price. Quoted per job, from plans or a site visit. Area is one factor; finish, stone exposure, edges, access and slab condition matter as much.
Questions
Will a polished floor show scratches?
All polished floors scratch eventually. Satin hides wear far better than high gloss. Felt pads, doormats and a pH-neutral cleaner make the biggest difference.
Do I need to tell my builder before the slab is poured?
Yes. The best polished floors are planned before the pour - slab strength, flatness, finishing and protection during the build all matter. We can talk to your concreter directly.
How much height does polishing take off the slab?
Between 2 and 4 mm at this finish, more for full stone exposure. Set-downs and door clearances need to allow for it.
