Mission Viejo is one of the largest master-planned communities ever built - and most of its concrete slabs were poured in the 1960s, ’70s, and ’80s. That means decades of cracks, spalling, and oil saturation that need expert remediation before any coating goes down. We do it right, so the finish lasts.

The Mission Viejo Concrete Challenge
Mission Viejo was developed primarily between 1965 and 1990, making it one of the largest and most deliberately planned communities in United States history. The trade-off for that legacy: a large share of its residential concrete slabs are now 35 to 55 years old. These slabs typically show significant cracking from decades of thermal cycling, moderate to heavy spalling at control joints, and deep oil saturation in homes that have been in the same family for decades.
Surface-level treatments and thin coatings fail on aged slabs. The cracks telegraph through within months. Oil-contaminated sections delaminate within a year. The ArmorClad approach - diamond grinding to a CSP 3 profile, full crack and spall remediation, and a 100% solids epoxy base that penetrates deeply into prepared concrete - is the only method that creates a permanent result on Mission Viejo’s mature slabs.
Mission Viejo also has one of the most active HOA landscapes in South Orange County. We provide written color compliance documentation ready for HOA board submission so the approval process doesn’t become a project-stopper.
Get a Mission Viejo QuoteProperties within the Lake Mission Viejo association carry strict architectural standards. We offer HOA-compliant neutral and warm-tone ArmorClad color palettes with written compliance documentation for your board submission.
The original Deane-built homes from the late 1960s and early ’70s have slabs that are now approaching 60 years old. These require the most thorough remediation - and reward it with a dramatic transformation that younger slabs can’t match.
Mission Viejo’s active adult community has its own HOA standards and many long-time residents looking to finally upgrade a garage floor that has never been coated. We’re experienced with Casta del Sol’s requirements and the unique slab conditions of its era.
Not all of Mission Viejo is older - newer sections built in the 1990s and 2000s have cleaner slabs with standard needs. We scale our remediation to what the slab actually requires, so you’re not paying for work that isn’t needed.
The System Behind the Finish
Mature slabs require a coating system engineered for deep penetration and permanent adhesion - not a surface-level product that looks good in photos but fails by year two.
Industrial diamond grinding opens the concrete pores to a CSP 3 profile - the only preparation method that creates true mechanical adhesion on aged, oil-contaminated, or previously sealed slabs. Learn why this matters.
Every crack, control joint, and spalled section is properly repaired before coating begins. We use structural epoxy injection and polyurea fillers matched to the concrete’s movement profile - not cosmetic patching that re-cracks.
Our base coat penetrates into properly prepared concrete at a molecular level. On aged Mission Viejo slabs, this creates an adhesion bond that surface-applied coatings simply cannot achieve - and it doesn’t shrink or leave pinholes on cure.
Our Process in Mission Viejo
For Mission Viejo’s older slabs, the preparation phase is everything. We invest the time in steps one and two so that the finished coating performs for a decade or more.
We inspect the slab for oil contamination, crack patterns, and spalling. Simultaneously, we review HOA color requirements and prepare compliant ArmorClad options for your board submission.
Full diamond-grind surface preparation, structural crack injection, and spall repair. For heavily contaminated slabs, we use specialized degreasing primers before the base coat to ensure adhesion.
100% solids epoxy base, decorative color chip or metallic broadcast, and UV-stable polyaspartic top coat. Most Mission Viejo garages are completed in a single day once prep is done.
Understand why diamond grinding is non-negotiable for aged concrete like Mission Viejo’s original slabs.
Pricing for a professional concrete coating depends on the condition of your slab and the total square footage. For most standard two or three-car residential garages in Orange County, our industrial-grade systems typically range from $5.50 to $7.50 per square foot. Heavily cracked or oil-contaminated slabs in older Mission Viejo neighborhoods may require additional remediation - we document all additional work transparently in your written quote before anything begins.
Learn Why We Do It This Way
Mission Viejo’s original slabs are some of the most challenging substrates in Orange County. Learn why acid-wash preparation fails on aged, oil-saturated concrete - and why diamond grinding is the only method that creates permanent adhesion.
