Installation guide

The essentials for handling and installing Crisp material. Everyone on the project should read the full installation manual before starting.

Before you order

Wood is a natural material. Small differences in size, colour and grain between boards are normal, and wood moves with humidity and temperature. Allow 15% extra for waste and board selection.

The essentials

1. Inspect on arrival. Report freight damage at delivery, and any other shortages or concerns within 10 days. Installation is final acceptance of colour and quality.
2. Store dry and ventilated. Keep bundles covered, at least 6 in off the ground, with the wrap loosened for airflow.
3. Acclimate. Let the wood reach a stable moisture content before installing, and check it with a moisture meter. Western Red Cedar and Western Hemlock may need up to 2 weeks.
4. Seal every field cut before installation.
5. Fasten with stainless steel. Nails must go at least 1.25 in into solid wood. No staples, T-nails or interior finish nails.
6. Install on a rainscreen. Use furring strips over a weather barrier, never directly on sheathing or house wrap.
7. Keep clearances and gaps. 8 to 12 in from the ground, 2 in from the roof, 1 in from decks. Leave 1/8 in at trim and corners, 1/4 in at metal, and 1/16 in at butt joints.

All construction is subject to local building codes. Mock-ups and installers experienced with coated architectural wood are strongly recommended.

Touch-up instructions

Every order ships with a gallon of touch-up stain matched to your colour.

• Surface clean, dry and dust-free. Stir the stain well before and during use.
• Apply between 5 °C and 25 °C (41 °F and 77 °F), ideally 21 °C (70 °F). Not in rain, frost, direct sun or on warm wood, and keep above 1 °C (34 °F) for 48 hours after.
• Brush on with a natural bristle brush, working the stain in to blend with the surrounding surface.
• Touch dry in 2 to 8 hours and recoat after 12 to 48 hours, depending on temperature.
• Clean brushes with warm soapy water. Store the can between 10 °C and 30 °C, sealed and protected from freezing.

Lunawood installation

Lunawood publishes its own installation guides. Where they are stricter than the guidance above, follow Lunawood. Key points from the Lunawood facade guide:

• Screws of at least A2 (AISI 304) stainless steel, at least twice the cladding thickness, heads flush.
• Pre-drill at 0.5 to 0.8 times the screw diameter, and always within 50 mm (2 in) of a board end.
• A ventilated cavity of at least 25 mm (1 in) behind the cladding.
• At least 300 mm (about 12 in) between the bottom of the cladding and the ground.
