HOLZ BIO INDUSTRIAL

Holz Bio Industrial is a ready-to-use, water-based chemical agent to modify wood into a durable material with extended service life.

The technology is respectful to the environment: it does not contain biocides, solvents, and other hazardous components.

Holz Bio Industrial penetrates deeply into the wood and chemically combines with its structure without preventing air circulation and forming any superficial layer.

Holz Bio Industrial is available in different colour solutions or colorless. You can order Holz Bio Industrial according to the color cards for individual orders. The product can be used independently or as a primer. If required, it can be over-coated with paints, varnishes and other decorative materials.

The efficacy is tested and approved internationally by accredited laboratories and in practice. According to the tests performed, Holz Bio Industrial modified timber is resistant to:

• Basidiomycetes (EN 113 + EN 73 & EN 84)
• Woodboring beetles (EN 47 + EN 73 & EN 84)
• Termites (EN 117 + EN 73 & EN 84)
• Blue stain fungi (EN 152)

Holz Bio Industrial treated timber meets the requirements of the following Use Classes defined in EN 335:2013 (Durability of wood and wood-based products):

• UC1: Internal use, not exposed to weathering.
• UC2: Internal use or undercover, risk of weathering.
• UC3: External use, above ground, exposed to weathering.

Based on laboratory and field tests, it is expected as follows after the treatment:

• 15 years as the default service life for decking exposed to weathering.
• 30 years as the default service life for cladding exposed to weathering.

Holz Bio Industrial is ready for use and cannot be diluted or mixed with other products. Holz Bio Industrial works based on absorption, not on the number of coats.

Both superficial and vacuum application methods are suitable for the correct treatment. The certified performance requires full timber impregnation.

The application method chosen must ensure the absorption required:

• Most wood species have a minimum absorption rate of 200 gr/m2, usually 300 gr/m2 (approx. 3,7 m2 per 1 litre).
• The absorption rate depends on a number of factors, i.e., wood species, rough-sawn wood, planed all round (PAR) wood, and moisture content.

Holz Bio Industrial treated timber does not require any additional protective coat. It can be over-coated where a final decorative finish is required. Before overcoating, the substrate must be dry and stable and meet the moisture content requirements of the chosen finishing product. A minimum of 7 days should pass before applying any further paints or finish coatings.

The drying times are dependent on absorption of the substrate and drying conditions (temperatures and humidity). Climate conditions like low temperatures and/or high relative humidity can lengthen the drying time.
