PRIME Series PVC Stair Nosing

Add a safe, finished edge to your deck stairs with IPATIO PRIME foamed PVC stair nosing boards. Available in 12-foot lengths and colours matching our full PVC decking line — Teak, Stone, Chocolate, and more — these nosing boards provide a rounded, slip-resistant profile for each step.

Manufactured from closed-cell foamed PVC, our stair nosing resists moisture, rot, and UV degradation without painting or sealing. The durable, low-maintenance material withstands Canadian freeze-thaw cycles and heavy foot traffic season after season.

Which part do you need? Stair nosing finishes the front lip of each step, and the same board works as deck edging. Deck boards are the walking surface, and fascia boards cover the exposed framing and joist ends. Most decks use all three, in one colour.

How much to order: multiply the width of your stairs by the number of steps, divide by 12 feet, and round up. Add one board for cuts, and order it with your deck boards and fascia so the colour matches from batch to batch.

Coordinates with IPATIO PRIME fascia boards and PVC deck boards for a unified look. Free shipping on most orders over $88*.

Stair nosing FAQ

Which colours is IPATIO PRIME stair nosing stocked in, and will it match the deck boards?

Six, all in 12 ft boards: Teak, Stone, Chocolate, Mahogany, Espresso and Milk Tea. The PVC deck boards are stocked in four of those — Teak, Stone, Chocolate and Mahogany — and the fascia boards in those four plus Milk Tea. So if you want the step nose, the walking surface and the fascia to read as one colour, choose from the four; Espresso and Milk Tea are nosing colours without a matching deck board.

Can stair nosing be cut on site, and does a cut end need finishing?

Yes. The boards come 12 ft long and cut with ordinary woodworking tools — use a fine-tooth blade and support the board close to the cut so the edge stays clean. Nothing is needed afterwards: the colour runs right through the foamed PVC, so a cut end takes no paint, stain or sealer, and with no organic content in the board there is nothing to rot or splinter. The hidden fasteners and starting clips on our decking accessories page are made for grooved deck boards, not for nosing.

Is PVC stair nosing slippery, and how does it handle a Canadian winter?

The profile is rounded with a non-slip, splinter-free surface, and the foamed PVC stays cooler underfoot than wood in summer. Because the board is waterproof the whole way through and holds no organic content, freeze-thaw cycles do not swell, rot or check it, and it never needs annual painting or sealing — its own specification puts the lifespan beyond 50 years with minimal care. Clear snow and ice off the steps as you would on any deck; the material itself asks for nothing special.
