Concrete Sealing in Los Angeles.
Sealing bare or ground concrete to lock out water, oil, and stains and to hold the color. We run both penetrating sealers (silane/siloxane that soak in and leave the surface looking natural) and topical sealers (acrylic or polyaspartic film with a matte, satin, or gloss sheen).
What concrete sealing actually is.
Sealing bare or ground concrete to lock out water, oil, and stains and to hold the color. We run both penetrating sealers (silane/siloxane that soak in and leave the surface looking natural) and topical sealers (acrylic or polyaspartic film with a matte, satin, or gloss sheen).
The system
- Penetrating silane/siloxane for a natural, non-film look
- Topical acrylic or polyaspartic in matte, satin, or gloss
- Resists water, road salt, oil, and efflorescence
- Re-coat schedule built into the written job spec
What it costs
Sealer type and coat count set it. Square footage and how much cleaning or stripping the slab needs before the first coat move it as well. We look at the concrete and give you a real number for your slab.
How long it takes
One working day for most floors. Walkable the next morning.
How long it lasts
3 to 7 years for acrylic topical; 7 to 10 for penetrating silane/siloxane; 10-plus for polyaspartic.
Where this fits
Garage floors, driveways, patios, decorative and stamped concrete, warehouse slabs, anywhere a bare slab needs stain and moisture protection.
How a concrete sealing floor actually gets poured.
01 Walkthrough
Owner on site. Moisture test of the slab. Photos of existing cracks. Palette options walked in person. Proposal in your inbox next morning.
02 Diamond grind
Surface prep to CSP-3 profile, HEPA vacuum, rapid-set polyurea on crack lines, re-grind. Where every floor lives or dies.
03 Pour
Resin mixed on site, broadcast or swirled to match the system. Signature work happens here. Notched-trowel finish before the working window closes.
04 Topcoat
Polyaspartic or polyurethane within the resin chemical window. Walkable 24 hours, full traffic 72 hours. Written job spec before we leave.
Where we install concrete sealing.
We pour concrete sealing across all of our service areas: Los Angeles County, Orange County, the Inland Empire, San Diego County, Ventura County, Kern County, and Santa Barbara County. The system itself is the same across cities. Substrate prep adjusts to local concrete age and moisture conditions.

Inland Empire & beyond
Three rules we do not break on a concrete sealing install.
Coatings that fail early usually fail at the prep, which happens before a single batch of resin is mixed. These are the steps we keep on every job, whatever the budget.
01. Calibrated moisture testing
Calcium chloride or relative-humidity sleeve test on every concrete sealing substrate before we order resin. If the vapor emission rate is above manufacturer spec, we apply a moisture-mitigation primer at our cost rather than gamble on the topcoat bond. Skipping this is the most common cause of the failed coatings we get called in to re-prep.
02. Diamond grind to spec
CSP-3 minimum for residential concrete sealing, CSP-4 for high-build commercial. Shot blasting and acid etching are cheaper shortcuts that fail the resin manufacturer’s adhesion spec. We grind, HEPA-vacuum, polyurea-fill every visible crack, and re-grind. The prep day is the day the floor lives or fails.
03. Spec sheet with the resin maker named
Every concrete sealing proposal we write names the resin manufacturer, the topcoat product, the substrate prep depth, the cure window, and the maintenance schedule. If a competitor’s proposal does not name these, you are buying on faith, not specs. Full liability and workers’ comp on every job.
Questions before the call.
What does concrete sealing cost in Los Angeles?
Residential pricing for concrete sealing in the Los Angeles market typically runs between the ranges quoted on our service pages, with the exact number determined by substrate condition, finish system, and square footage. Commercial pricing is always project-specific.
Every price we give comes after we have seen the slab. We come out, spend about 30 minutes on a free walkthrough, and send a fixed-price proposal the following morning. Nothing gets added by change order once the work starts.
How long does concrete sealing take to install?
Plan on two to three working days for a typical home, counting prep through the final topcoat. Commercial floors and bigger residential jobs take longer, anywhere from four to fifteen days, set by the system spec, the slab’s condition and the square footage.
The polyaspartic topcoat makes the floor walkable in 24 hours after the final coat. Full vehicle traffic returns at 72 hours.
How long will my concrete sealing last?
Properly installed resinous floor systems are not cosmetic. They are a chemical bond to the substrate. Residential floors are engineered for lifetime adhesion to the slab.
There are two answers, depending on the floor. Residential: the base resin holds, and the topcoat may need a refresh at 8 to 12 years with heavy use. Commercial: we spec the system to the traffic and chemistry it will face, and the resin layer typically lasts 10 to 25 years.
Can you match a specific color?
Metallic pigment can be mixed to any color you bring us. A few we have poured: deep teal, matte slate and mother-of-pearl.
Flake systems come in pre-blended color packs and unlimited custom blends. Quartz comes in 14 standard colors plus custom mixes. Decorative concrete colors are added integrally during the pour or applied as a topical stain post-cure.
How does the install process actually work?
We start by testing the slab for moisture during the walkthrough, so we know what is coming up through the concrete before we coat it. The second stage is grinding to a CSP-3 profile and fixing cracks. Third is the pour, where the broadcast and any signature work happen. Fourth is the polyaspartic topcoat, followed by an inspection with you and a written spec of what we installed.
What happens after the floor is poured?
Nothing much, which is the point. Once the cure window passes the floor is yours, and the base resin stays bonded to the slab for as long as the floor is there.
Day to day, the floor maintains with a damp mop. No waxing, no sealing, no annual service appointment. The system is engineered to live without us.
What makes Concrete 2 Coatings different from other contractors?
Prep. When a coating peels or looks wrong, the cause is usually a step somebody skipped before the resin went down. We diamond-grind every slab to CSP-3, HEPA-vacuum it and grind it again, and the owner is there for that work on every job. We are a local outfit, no franchise, licensed across coatings, decorative concrete and structural slabs.
