Concrete Floor Repair and Coating in Sacramento, CA

A coating is only as good as the concrete underneath it. Many Sacramento slabs — particularly in 1960s-80s garage construction, older commercial buildings, and basements reaching end-of-life — have surface damage that prevents a coating from bonding properly or looking right. Sacramento Epoxy Floor Pros does concrete repair and coating as one job: we repair cracks, fill divots, resurface spalled areas, and then apply the coating system over the restored surface. The result is a coating that bonds correctly, looks even, and is warranted as a complete system. Call (916) 619-2368 for a free on-site assessment.

Why Concrete Repair Before Coating Matters

Coating manufacturers don't warranty coatings applied over actively cracking or structurally compromised concrete. The reason: a crack in the substrate telegraphs through any coating applied over it within months. A divot or spalled area shows as a visible defect in the finished floor. Moisture vapor emission through cracks creates blistering. The coating fails not because the coating is bad — but because the substrate it was applied over is.

Concrete repair before coating is the standard professional approach. We don't try to coat over damaged concrete and hope for the best. We assess the substrate, identify what needs repair, document the scope, and complete the repair before the coating goes down. The repair itself is part of the coating warranty when done as one project.

Common Concrete Conditions We Repair

• Static and moving cracks. Sacramento slabs commonly develop cracks from shrinkage, settlement, or seasonal cycling. We classify cracks at assessment — static cracks get rigid epoxy filler; moving cracks (control joints, expansion joints) get semi-rigid polyurea.
• Spalled surfaces and chipped edges. Surface aggregate exposure, chip-outs at edges, and freeze-thaw damage from Sacramento's occasional cold snaps and freeze-thaw cycles in foothills areas.
• Divots and pop-outs. Localized depressions from rebar corrosion, embedded aggregate failure, or impact damage.
• Failed prior coatings. Existing peeling, blistering, or de-laminated coatings need full removal before any new coating goes down. Diamond grinding is the standard removal method.
• Joint failures and degradation. Control joints that have lost their filler, expansion joints with degraded sealant.
• Surface contamination. Oil stains, chemical penetration, prior maintenance products that prevent coating bond.

Project Details

Our Repair + Coating Process

1. 1Free on-site assessment. We inspect the slab and identify every condition that requires repair. We classify cracks, measure damage areas, and assess substrate moisture.
2. 2Written estimate with repair scope itemized. Linear feet of cracks, square feet of patching, prior coating removal, and the coating system to be applied.
3. 3Diamond grinding to expose substrate. Full grinding of the floor surface to remove failed coatings, contamination, and create the CSP profile.
4. 4Crack routing and filling. Each crack routed and filled with appropriate polyurea or epoxy. Static cracks: rigid epoxy. Moving cracks: flexible polyurea.
5. 5Patching and resurfacing. Divots and spalled areas patched with polymer-modified compound. Extensive damage gets full resurface with polymer-modified cementitious overlay.
6. 6Final substrate prep. Light grinding of patches to feather edges. Vacuum cleaning to remove all dust.
7. 7Coating system installation. Primer, basecoat, chip broadcast, topcoat applied per system specification.
8. 8Cure and handoff. Walk-on within 4-24 hours; drive-on within 24-72 hours. Full warranty documentation.

When Concrete Repair Is and Isn't Enough

Most slab issues that affect coating performance can be repaired before coating. What can't be repaired with the techniques above:

Active foundation movement. If the slab is actively moving due to foundation settlement or expansive soil behavior, surface repair is futile.

Severe substrate failure. Slabs with extensive surface delamination where the top inches are compromised may require full slab replacement.

Active moisture vapor emission beyond mitigation capacity. Slabs with MVE exceeding the rating of available vapor-block primers require more extensive mitigation.

Materials We Use

Warranty in Detail

When concrete repair is part of a coating project, the repair work is covered by the same workmanship warranty as the coating itself — typically 5 years on residential, varying by system on commercial. If a repaired crack reopens or a patch fails within the warranty period, we return and address it.

What the combined warranty does not cover: new cracks or damage from substrate movement outside the original scope, damage from operational conditions outside the rated load class, or chemical exposure beyond rated resistance.

Sacramento-Specific Considerations

The Sacramento metro has a wide range of slab ages and conditions. 1950s-60s central Sacramento, Land Park, and East Sacramento residential slabs are now 60+ years old, often unreinforced, exhibiting decades of settlement and shrinkage cracking. 1970s-80s East Sacramento and Citrus Heights construction has slabs at the age where settlement effects may be appearing. Newer Roseville, Elk Grove, and Rocklin construction generally has fewer slab issues but builder-grade concrete still develops shrinkage cracks within the first 1-2 years.

For Sacramento's older below-grade slabs — basements in Folsom, Granite Bay, East Sacramento, and the older established neighborhoods — concrete repair before coating is essentially universal because of decades of moisture and seasonal cycling.
