Grinding
A walk-behind grinder with coarse metal-bond diamonds removes coatings, glue and surface laitance and gives the sealer a clean, even surface to grip. This is the coarse stage of a polish, and it stops there.

Owners who want a tidy, finished slab but not the cost of a full polish are who this service is for. We grind the concrete with coarse diamond tooling to clear old coatings and open the surface, and then apply a sealer that protects the floor and sets its sheen, here in Casa Grande.
It suits garages, workshops, small shops and plain rooms, in Casa Grande and in nearby Maricopa and Coolidge. Where a floor does need a full polish, the home page explains the difference.
What a grind-and-seal floor includes
Crack and joint repair
Cracks and control joints are filled before sealing. Filling makes them less obvious and keeps debris out of them, but they remain part of the floor.
Sealer
A topical sealer goes on the ground slab and sets how glossy the floor looks. It is a film on the surface, so it can wear where traffic is heaviest and can be recoated.
Optional color
A dye or stain can go on after grinding and before the sealer, and our stained and dyed page covers those choices.
What grind and seal means
Contractors describe grind and seal as grinding the concrete and then applying a protective sealer instead of working through every polishing step. No building standard defines the term, so the quote you receive should list the steps rather than rely on the name.
The difference from a polish is where the finish comes from. A polished floor gets its shine from the concrete, hardened with a densifier and cut with finer and finer diamonds. A grind-and-seal floor gets its sheen from the sealer on top.
Grind and seal or polish
Three things decide it: budget, how the floor is used and what the slab is like. A garage, a workshop or a storage room may not need the look of a full polish, and a ground and sealed floor costs less effort because it has fewer steps. A living area with strong daylight or a floor you want to look deep and reflective may point to a polish.
A badly pitted or patched slab can look better with a sealer than with a high polish, because gloss shows flaws. If you cannot tell which fits, a trial spot on the actual floor answers it faster than a description.
Sealer finishes
Sealers range from matte to glossy. A matte sealer hides marks and gives a quieter look, and a glossy one brings out color and reflects more light. The finish is chosen with the floor and its use, and the product is picked to suit the slab.
Grind and seal questions
How much does grind and seal cost? It depends on the size of the floor, the condition of the slab and how much covering has to come off, so the quote follows a look at the floor.
How long does a sealed floor last? There is no single number. A sealer wears with traffic and cleaning, and it is recoated rather than polished back.
What is a cheaper alternative to polished concrete? Grind and seal is one: it keeps the concrete and drops the later polishing steps.
Sealer needs bare concrete underneath, which means a floor hidden under carpet or tile begins with concrete floor restoration. A garage owner weighing this finish against a full polish can compare notes on polished concrete garage floors. The rest of the range is on the Casa Grande Polished Concrete home page.
