Grind & Seal
Concrete Grind & Seal Illawarra & South Coast
Looking for a high-performance concrete floor system? A professional concrete grind and seal is the ultimate high-utility flooring solution for residential homes, retail spaces, and commercial properties across Wollongong, Shellharbour, Kiama, and Nowra.
Residential Grind & Seal (Premium Home Comfort)
Our domestic system utilizes a dedicated 50-grit diamond hone and a premium 4-coat topcoat sealer system to deliver the ideal balance of durability, style, and cost-efficiency for modern living areas, garages, alfrescos, and extensions:
- Family & Pet Friendly: The 4-coat topical barrier provides a highly scratch-resistant, pet-proof, and stain-resistant surface.
- Easy Maintenance: It creates a seamless floor that is incredibly easy to mop and never traps dust, pet hair, or allergens like carpet or tile grout lines do.
Commercial Grind & Seal (Heavy-Duty Performance)
Engineered for commercial fit-outs, industrial facilities, and high-traffic tenancies where strict functional and chemical requirements must be met:
- 100% Non-Porous Barrier: The premium topcoat sealer system creates a completely impermeable surface essential for commercial hygiene. Penetrating sealers are often unsuitable for high-spill zones because chemicals, oils, and heavy foot traffic can break down the unprotected concrete matrix over time.
- The “Bad Slab” Fixer: If a renovation or commercial floor is structurally uneven, damaged, or poorly poured with footprint dips and rough screed ridges, a high-build topcoat sealer system shaves down the high spots and buries underlying imperfections beneath smooth, self-leveling topical clear coats.
- The “Rustic Industrial” Cafe Look: Highly sought after for trendy modern spaces and retail venues. Instead of hiding the slab’s unique history, this system seals away concrete dust while intentionally highlighting natural cracks, trowel burns, and unique color shading as raw architectural features.
Concrete Grind & Seal Process
- The Coarse Metal Cut: Aggressive metal-bond diamonds level out high ridges, flatten uneven tamps, and reveal the aggregate.
- The Double Grout (Optional): Depending on if you want grout or not, a heavy-duty polymer grout is applied to patch micro-pinholes, voids, and surface fissures.
- The Resin Hone (Optional): The slab is refined using flexible resin pads to eliminate scratch marks and create a smooth profile.
Frequently Asked Questions
Answer: A Grind and Seal is a highly popular, two-step flooring system. First, we use planetary diamond grinding machines to mechanically shave the surface of your concrete slab, removing defects and exposing your choice of light or full stone aggregate. Second, we thoroughly clean the slab and apply a premium, clear topical protective coating—such as an industrial polyurethane, polyaspartic, or epoxy sealer. This clear coating seals the floor from the top down, giving you a beautiful glossy or matte finish that protects the concrete underneath.
Answer: For a standard residential living space or retail shop fit-out, a professional Grind and Seal installation typically takes 2 to 3 days from the initial diamond grind to the final topcoat application. The surface is ready for light foot traffic within 24 hours of completion, and you can safely return heavy furniture or vehicles to the floor after 5 to 7 days.
Answer: No. While budget DIY clear sealers scratch and wear thin quickly, ProSand uses premium, commercial-grade polyurethanes that are highly scratch and abrasion-resistant. For high-traffic retail spaces or homes with busy pets, we apply specialized, hardened topcoats that easily resist micro-scratches, scuff marks, and household chemical spills, keeping your floors looking pristine for years.
Answer: Sealing creates a completely non-porous surface, making maintenance incredibly easy. Dirt, dust, and liquids cannot penetrate the concrete, so regular maintenance requires nothing more than a quick sweep or a microfiber dust mop. For washing, simply use a damp mop with warm water and a splash of a mild, pH-neutral floor cleaner. You should strictly avoid harsh chemical bleach or abrasive scrubbing pads, as these can dull the clear protective topcoat over time.
