Concrete as the finished floor
Grind and seal combines surface grinding with an applied sealer. It is a different finish from mechanically polished concrete, where a series of finer grinding and polishing steps develops the surface.
Start with the slab you have
Existing marks, aggregate, cracks and previous repairs influence the appearance. Photos help us discuss the options, but the achievable finish depends on the slab. A consistent colour or stone exposure cannot be assumed from a small sample.
Choose a finish for the space
Tell us how the floor will be used and whether it is indoors, outdoors or in a garage. Discuss the look you want, cleaning, slip considerations and sealer suitability before selecting the finish.
Plan for the floor to be clear
Grinding and sealer application need access to the floor. Drying and return-to-use times depend on the selected product and conditions, so timing is confirmed as part of the job rather than promised in advance.
Grind and seal or polished concrete?
- Grind and seal
- The slab is ground, then an applied sealer provides the finished surface. The selected sealer affects appearance, maintenance and return-to-use time.
- Mechanically polished concrete
- The concrete surface is refined through progressively finer grinding and polishing steps. The finish still depends on the slab and the agreed process.
These are different scopes, so compare quotes for the same system and exposure. See polished concrete floors if that is the finish you have in mind.
Common questions
Can an old slab be ground and sealed?
It depends on the slab and the finish you want. Previous coatings, repairs, cracks and contamination can affect both appearance and the preparation needed.
When can the floor be used again?
Timing depends on the chosen sealer and site conditions. Confirm the product’s cure and return-to-use requirements as part of the quote and schedule.
