Sansin WoodForce™

Sansin WoodForce is a high-performance, ultra-low-VOC (volatile organic compound) water-borne penetrating exterior wood coating system that provides a naturally weathered look. Over a short time, the wood will weather uniformly to a beautiful silver-grey tone.

Silva offers two WoodForce systems for a weathered appearance: Wood Force Clear and Wood Force Accel.

Wood Force Clear is virtually invisible once applied and allows the wood to develop the weathered wood look gradually over time*. This system requires two coats of Wood Force Clear.

Wood Force Accel creates the naturally weathered wood look more quickly. This system requires a base coat of Wood Force Accel followed by a second coat of Wood Force Clear. An optional 3rd coat of Wood Force Clear can also be applied.

WoodForce is also available in two stylish grey colour tones: Pearl Grey and Sky Grey.

* Weathering is subject to factors like location, climate, exposure, wood species, and building design.

How it Works

Sansin WoodForce allows exterior wood to naturally weather while offering exceptional water repellency and protection from UV, moisture, and blackening. It aggressively repels water while allowing the wood to breathe.

WoodForce reduces water absorption by up to 74% during wetting periods, reducing swelling to keep the wood dimensionally stable. This high-performing coating system provides exceptional protection and will not break down with exposure to sunlight, retaining its water-repellency and protecting against weathering and wood rot. Wood Force erodes gently over time, so long-term maintenance is easy – the end-user can apply a fresh coat of WoodForce, as needed.

Sansin WoodForce will not peel and can be used for a wide range of interiors and exterior applications, including cladding, decks, fences, shingles, garden structures, and garden furniture.

Approximate Coverage

A 11.35l tin will cover approximately 27.9 - 55.8 square metres for a single coat depending on the type of wood, texture and porosity.
