Concrete Sealers — Penetrating & Film-Forming, BC Stocked
Professional Concrete Sealer Systems | Penetrating · Film-Forming · Acrylic · Polyurethane
Concrete sealers protect horizontal and vertical concrete surfaces from moisture, chloride ingress, freeze-thaw damage, and surface wear. Canopus Supply carries both penetrating sealers — which chemically bond with the concrete substrate — and film-forming sealers that provide a surface barrier with varying sheen levels. Suitable for driveways, warehouse floors, exterior slabs, and architectural concrete. Available in North Vancouver for contractors across the Lower Mainland and BC.

| Penetrating / Silane-Siloxane | Chemically bonds within substrate; invisible finish | Exterior slabs, driveways, freeze-thaw exposure |
| Acrylic Film-Forming | Surface film; gloss or matte finish | Decorative concrete, stamped concrete, interior floors |
| Polyurethane Sealer | Durable surface film; high chemical resistance | Commercial floors, warehouses, high-traffic areas |

Frequently Asked Questions
Do I need to prepare the surface before sealing?
Yes. The concrete must be clean, dry, and free of contaminants, existing coatings, and curing compounds. Light grinding or acid etching may be required depending on the sealer type and substrate condition.
How long does a concrete sealer last?
Penetrating sealers typically last 5–10 years. Film-forming sealers may require reapplication every 1–3 years depending on traffic and exposure. Confirm expected service life with the specific product data sheet.
Can I apply a sealer over an existing coating?
Compatibility depends on the existing coating and the sealer type. Contact us before applying a sealer over any previously coated surface.
