Installation Guide

Key points for installing WANNABES WPC products. For large or special projects, please consult a professional installer or our technical support.

1. Base Requirements

The installation base must be level, solid and well-drained. A joist (keel) substructure is recommended to ensure air circulation beneath the boards. Joist spacing should be within 30 cm.

2. Expansion Gaps (Critical)

Side to side: whichever fixing method is used (clips or butt joints), leave an expansion gap of at least 3–7 mm between board sides.
End to end: leave at least 5–8 mm where board ends meet.
Perimeter: never fix boards tightly against any rigid structure (walls, posts, curbs). Leave at least 10 mm of expansion space on all sides.

3. Fixing

Always use WANNABES recommended stainless steel / aluminum clips and screws. Two boards must never share a single fastener.
All screw holes must be pre-drilled, with the drill diameter slightly larger than the screw shank. Never hammer screws in directly.
Do not over-tighten — boards must retain slight freedom of movement.

4. Cutting & Finishing

After cutting, sand the cut edges and, where applicable, apply the dedicated sealing glue to improve appearance and moisture resistance.

5. Cleaning & Maintenance

Routine cleaning with water, a neutral detergent and a soft brush is sufficient. Avoid strong acids, alkalis or corrosive cleaners. Stubborn stains can be wiped with alcohol or a dedicated cleaner.

Decking Installation Steps

Lay the joists

Level the ground, lay the joists at a spacing of 30 cm and fix them. Install the first board, fixing screws through the side groove.

Install the fasteners

After fixing the first board, install the plastic clips. Do not fully tighten the screws yet — this makes fitting the second board easier.

Lay the boards

Fix the second board, then repeat steps 2 and 3 across the whole area.

Finish the edges

Once all boards are installed, fit the edge trims with screws at a spacing of about 40 cm.

Please note: This guide covers general key points only. Specific installation plans should be adjusted to the actual project design and local climate conditions.
