What is the best decorative concrete finish for a front porch in NB?

For a front porch in New Brunswick, the most durable decorative concrete finishes are exposed aggregate and textured broom or brush finishes — both provide slip resistance, stand up well to freeze-thaw cycling, and require less intensive maintenance than stamped concrete in NB's climate. Stamped concrete is beautiful but demands more upkeep, which is why many NB homeowners and contractors recommend exposed aggregate for porches specifically.

Exposed aggregate is achieved by seeding decorative stone into the surface of freshly poured concrete and then washing away the surface paste to reveal the stone. The aggregate choices available in NB include natural river pebbles, crushed granite, and various coloured stones that can complement your home's exterior. The result is a naturally textured, slip-resistant surface that looks attractive year-round. Exposed aggregate hides surface wear well as it ages — minor weathering actually enhances the stone-in-concrete look rather than detracting from it. It costs $10 to $16 per square foot for a porch application.

Stamped concrete for a porch offers the most dramatic visual impact — patterns like flagstone, slate, cobblestone, or tile can transform the appearance of a plain concrete porch into something that looks custom-built. The trade-off in NB is maintenance: the sealer must be refreshed every 1 to 2 years on a porch that faces the elements, and the stamped texture requires more care in winter. A porch that is under a covered overhang is a better candidate for stamped concrete than a fully exposed one. Expect $14 to $22 per square foot.

Troweled concrete with integral colour is an underrated option for NB porches. A smooth steel-troweled finish with integral colour pigment (added directly to the mix) gives you consistent colour throughout the slab — so scratches and chips do not expose grey concrete beneath. The smooth finish is easier to clean, and integral colour is more durable than colour hardener applied to the surface. Add a broom or broomed-slate texture for slip resistance. This runs $12 to $18 per square foot.

Whatever finish you choose, two things are non-negotiable for an NB porch. First, the concrete mix must be air-entrained (4 to 7% air content) at 32 MPa minimum — porches see direct weather, road salt splash, and snow shovelling. Second, proper drainage slope (minimum 1/8 inch per foot away from the house) must be designed into the porch from the start — water pooling on a porch surface accelerates deterioration of any finish.

For front porches in exposed locations in Moncton, Fredericton, or Saint John, exposed aggregate tends to deliver the best combination of durability, low maintenance, and visual appeal over the 20 to 30 year life of the slab.
