DIY Correx Sign Installation

Correx (corrugated plastic) signs are light, cheap, and tough — but only if they're installed so the wind doesn't turn them into kites. Here's how we recommend putting them up.

Choose your mount

• H-stake (wire frame): the standard for lawn/estate-agent signs. Slides into the flutes on the back; pushes into soft ground.
• Ground spike: a single steel spike for heavier boards in firm soil.
• Screw/wall fix: for fences, walls, or shopfronts — use stainless screws and washers.
• Sandbags/water base: for pavements where you can't stake (check local bylaws).

Lawn / soft ground (H-stake)

1. Push the H-stake into the ground at the spot — avoid rocks.
2. Slide the sign's vertical flutes onto the stake's arms.
3. Press down until the board sits flush; the stake should disappear behind it.

Firm ground (ground spike)

Drill a pilot hole if the soil is hard, then hammer the spike through the board's flute. Don't hammer the board directly — you'll crush the flutes.

Walls and fences (screw fix)

Pre-drill through the board (drill bit slightly larger than the screw shank), then fix with stainless screws + washers so wind can't lever the head through.

Wind-loading reality check

A 600 × 900 mm Correx board is a sail. In open, windy spots:

• Use two stakes or a wider base.
• Lower the board (shorter = less leverage).
• For semi-permanent outdoor use, consider rigid ABS or composite boards instead of Correx.

Keep it legal

Don't block sightlines at intersections, and check municipal rules before roadside placement.
