Concrete Sealcoating
Lock in the clean.
Sealcoating is the step after pressure washing that makes the result last. A professional-grade sealer protects your concrete from oil penetration, staining, UV damage and weathering — keeping it looking clean for years, not months.
Unsealed concrete is porous. Every spill — oil, paint, rust, organic matter — penetrates the surface and bonds to the concrete matrix. Once in, most stains are extremely difficult or impossible to fully remove. Sealcoating closes those pores, creating a barrier between your concrete and the world above it.
There are two categories of sealer: penetrating sealers and topical sealers. Penetrating sealers soak into the concrete and react chemically with the silica matrix, becoming part of the slab. They are invisible when dry and last 5–10 years. They are the right choice for most residential concrete.
Topical sealers sit on top of the surface and form a protective film. They can be matte, satin or gloss finish and enhance the surface colour — a popular choice after exposed aggregate cleaning. They typically last 2–4 years before recoating.
We always pressure wash before sealing. The concrete must be completely dry before sealer is applied.
What we work on.
How we do it.
The concrete must be freshly cleaned and completely dry. We check moisture content with a meter on the day of sealing.
We discuss the options with you — penetrating vs topical, matte vs satin vs gloss — and recommend the right product for your surface type.
Sealer is applied evenly using a roller for topical sealers or a pump sprayer for penetrating sealers. We work in systematic passes to ensure full, even coverage.
First coat is allowed to become touch-dry before the second coat is applied. Two coats are standard — single-coat applications are insufficient for proper protection.
We advise you on cure times and provide care instructions — what to avoid in the first 72 hours, and how to maintain the sealed surface.

We won't seal dirty concrete. Sealer applied to a soiled surface permanently traps the contamination.
We check concrete moisture content before sealing. Too much moisture and the sealer won't bond correctly.
One coat is not adequate protection. Two coats are standard on every job.
Exposed aggregate needs a different sealer than stencilled concrete. We specify the right product.
