Description and properties

Wood Bioprotective Concentrate "Concentrat 1:9". Green by Bayris is intended for the protection of structural timber elements (attic structures, timber frames, log constructions, roof truss systems, etc.) and construction timber (flooring, fences, gazebos, decking boards, posts, etc.) against biological deterioration. It prevents the development of algae, lichens, mosses, mould fungi and blue stain fungi. It is also used for protection against and prevention of wood-destroying insects. Suitable for domestic, professional and industrial use under Use Classes 1–4.1 in accordance with EN 335-1:2010 (the use class depends on the application method).

Wood Bioprotective Concentrate "Concentrat 1:9". Green by Bayris is a concentrated treatment containing fungicides, algicides, insecticides and performance-enhancing additives, with a green identification pigment. It changes the colour of the timber after application (light green), remains resistant to leaching during service life and provides effective timber protection. The colourant serves only as an application indicator, has no biocidal properties and may gradually leach out over time.

Characteristics

Wood Bioprotective Concentrate "Concentrat 1:9". Green provides long-lasting protection against a wide range of biological threats. Suitable for both deep and surface impregnation of timber species with moderate to high absorbency. Does not alter the timber structure, does not cause chemical degradation of cellulose in the surface layer and does not form a polymer film or salt deposits. Classified as having low corrosive activity towards ferrous metals.

Application

Application should be carried out at substrate and ambient temperatures between +5°C and +25°C and at a relative air humidity of 50% to 75%. Stir thoroughly before use. The working solution should be prepared on site at a dilution ratio of 1:9 (1 litre of concentrate to 9 litres of clean or distilled water).

Surface preparation
The substrate must be visually clean, free from dust, signs of biological activity, stains and decay, and suitable for treatment (mechanically clean if required). The moisture content of the timber must not exceed 25%.

The application method depends on the required use class.

Timber protection should be carried out as follows:
- for Use Class 1 or 2: apply one or two coats using a brush, roller or spray application. A second coat should be applied after an intermediate drying period of at least 4 hours at 20°C;
- for Use Class 3: apply by immersion for a minimum of 6 hours. Double treatment requires an intermediate drying period of 24 hours at 20°C under cover;
- for Use Class 4: treatment should be carried out in autoclaves.
Immediately after use, clean tools with water. Areas where timber has been treated may be used after three days of intensive ventilation. Fixation time: under normal conditions, the treatment is fully fixed within the timber after 48 hours for Use Classes 1 and 2, and after at least 14 days for Use Classes 3 and 4. Once fully dry, the timber may be coated with any decorative or protective finish.

Coverage

220–350 ml/m² depending on timber species, application method, timber absorbency and the dimensions of the treated surface. Actual consumption may increase depending on the complexity of the timber elements, associated losses and timber moisture content.

Drying time: 4–6 hours depending on timber species and moisture content.
