Grind & Seal/Concrete Sealing in Southern New Hampshire
A grind-and-seal finish is a clean, modern, and durable way to enhance concrete floors without the thickness of an epoxy coating. This system combines mechanical grinding with a protective sealer to create a smooth, low-maintenance surface that looks great and performs well in many areas of the home.
What Is a Grind & Seal?
A grind-and-seal system removes the top layer of concrete through mechanical grinding and then applies a protective sealer. The result is a polished, matte, or satin finish that showcases the natural concrete while adding resistance to moisture, staining, and everyday wear.
This flooring option is perfect for homeowners who want a clean, durable surface without the full build of an epoxy coating.
Clean, Natural Concrete Look
Enhances the existing concrete rather than covering it, giving basements, garages, or utility areas a modern, industrial aesthetic.
Durable & Long-Lasting Surface
Withstands foot traffic, storage, seasonal temperature changes, and minor moisture exposure.
Lower Maintenance
Easy to clean and doesn’t produce concrete dusting. A simple sweep or light mop keeps the floor looking fresh.
Resistant to Stains & Moisture
The sealer protects against spills, humidity, and moisture absorption—ideal for Southern NH basements and garages.
Grind & Seal Installation Process
A grind-and-seal installation follows a detailed, step-by-step process designed to create a smooth, clean surface and a long-lasting sealed finish.
1. Surface Inspection
The concrete is evaluated for cracks, moisture, or weak areas that may need repair prior to grinding.
2. Mechanical Grinding
The surface is ground to remove the top layer, old coatings, stains, and imperfections, creating a clean, even base.
3. Crack Repair (If Needed)
Any cracks or damaged areas are repaired to ensure a smooth finished surface.
4. Cleaning & Prep
The floor is vacuumed and cleaned using dust-controlled equipment.
5. Sealer Application
A high-quality concrete sealer is applied to protect against stains, moisture, and daily wear.
6. Optional Additional Coats
Depending on the finish chosen, extra coats can be applied for added sheen or durability.
Matte Sealed Concrete
A soft, low-sheen finish that blends well with any interior or utility space.
Semi-Gloss Finish
A polished appearance that reflects light and brightens the room.
Lightly Polished Concrete
A cleaner, smoother surface achieved through additional grinding passes before sealing.
