Concrete floors in Minnesota face a year-round battle against drastic seasonal temperature changes. From negative-20-degree winter polar-vortex temperatures to 90-degree humid summer afternoons, concrete slabs constantly expand and contract. 

To help property owners address these temperature-related flooring problems, ACT Restoration offers professional grind and seal concrete floor services.

Grind and seal concrete floors are an increasingly popular choice for Minnesota commercial businesses and homeowners. This concrete restoration method provides a sleek, industrial, and customizable aesthetic that is uniquely equipped to handle 110-degree seasonal temperature swings. 

Let’s take a closer look at how Minnesota property owners can extend the life of concrete flooring with our grind and seal process.

Grind & Seal Restoration Combats the Concrete Freeze-Thaw Cycle 

The biggest problem that Minnesota concrete floors endure is the freeze-thaw cycle. Because concrete is naturally porous, an unsealed concrete floor acts like a giant sponge. When snowmelt, water, or rain seeps into the concrete pores and freezes, the trapped moisture expands by approximately nine percent. This internal pressure causes concrete spalling, pitting, and cracks.

A professional grind and seal application combats concrete spalling because the mechanical grinding phase removes the weak, porous top layer of the concrete to expose the stronger aggregate beneath. 

The subsequent sealing phase fills those open concrete pores with a protective barrier, preventing moisture from penetrating deep enough to cause the concrete slab to expand and break.

The Flexible Seal Adapts to Concrete Temperature Swings & Thermal Shock 

Extreme midwestern temperature swings frequently cause concrete slabs to physically move. 

For example, a 100-foot commercial concrete slab can move nearly half an inch between a hot August day and a freezing January night. 

This physical shift is called thermal movement, and thermal movement can cause rigid floor coatings, like DIY epoxy kits, to become brittle, crack, or peel off entirely.

The high-quality concrete sealants applied during ACT Restoration's grind and seal process are engineered with far greater flexibility than standard rigid epoxies. Premium concrete sealers act more like hard rubber than a sheet of glass, allowing the protective floor coating to move seamlessly with the concrete slab as temperatures change throughout the Minnesota seasons.

Professional-Grade Sealant Protects Concrete Against Winter Salt + Slush

In Minnesota, winter weather brings more than just snow and ice to commercial warehouses, schools, and homes. Corrosive deicing substances used to combat winter weather, such as rock salt, magnesium chloride, and sand, are constantly tracked indoors, causing severe concrete degradation.

Without a protective concrete seal, corrosive salt water penetrates the concrete slab and can eventually reach the internal steel rebar. Saltwater reaching the internal rebar causes rust and expansion, which will destroy the concrete floor from the inside out.

Our concrete floor restoration experts solve this winter salt problem by applying professional-grade concrete sealants to create a non-porous, hydrophobic floor surface. A hydrophobic grind and seal finish ensures that corrosive salt and winter slush sit on top of the concrete floor rather than soaking into the porous slab. 

Facility managers and homeowners can simply squeegee the winter mess and clean the area, leaving the concrete pristine underneath.

Top 3 Maintenance Tips for Concrete Floor Longevity 

To get the maximum lifespan out of grind and seal concrete floors, ACT Restoration recommends following these professional concrete maintenance tips:

1. The Concrete Water Test: Once a year, property owners should pour a small amount of water on the grind and seal concrete floor. If the water beads up, the concrete sealer is intact. If the concrete darkens and absorbs the water, the floor requires a professional reseal from ACT Restoration.

2. Remove Rock Salt Promptly: While a high-quality concrete sealer protects the flooring surface, heavy piles of rock salt left to sit for months can eventually pit and damage the protective finish. Property managers should sweep up and remove winter rock salt regularly.

3. Clean Concrete Regularly: Floor maintenance personnel should clean grind and seal concrete floors daily during the winter months. Using a broom or microfiber dust mop removes abrasive surface debris. Facility managers should then wet mop the concrete floors with lukewarm water or a pH-neutral cleaner to safely remove grime and dirt without degrading the sealer.
