Wood preservative Drewnochron Impregnat extra film-forming mahogany 2.5L

Drewnochron Impregnat extra film-forming mahogany 2.5L is a pigmented wood preservative designed for interior and exterior wooden surfaces. The product combines active protection against moisture, fungal decay and UV-induced colour changes with a decorative mahogany-coloured coating. Supplied in a 2.5-litre container, it is suitable for use on fences, doors, windows, garden furniture and wooden cladding, providing both a protective layer and a finished appearance.

Advantages

The film-forming formula creates a continuous pigmented layer that reduces water penetration and slows down degradation caused by fungi and weathering. The mahogany tint evens out natural colour variations in wood and provides a uniform finish while allowing subsequent maintenance coats. Being suitable for interior and exterior use, the product simplifies treatment of a wide range of wooden elements and reduces the need for frequent repairs.

Suitable for

• Exterior wooden fences and gates
• Wooden doors and window frames
• Garden furniture and outdoor decking
• Wooden cladding, facades and siding
• Interior wooden elements where a pigmented protective coating is desired

When it may not be suitable

This film-forming preservative may not be suitable where a fully transparent, oil-like soak-in finish is required, or when a natural, untreated wood look is specifically desired. It is not intended for use on non-wood materials and should not be applied to wet or heavily decayed timber without prior preparation.

Key specifications

• Type: film-forming wood preservative
• Colour: mahogany (pigmented)
• Volume: 2.5 litres
• Application areas: interior and exterior wood
• Main protective properties: moisture resistance, fungal decay protection, UV protection

How to use

Ensure the wood surface is dry, clean and free from dust, grease and loose fibres. Stir the product thoroughly before application. Apply evenly with a brush, roller or low-pressure sprayer following the grain of the wood. For new or highly absorbent surfaces, apply a primer coat if recommended by the manufacturer, then apply one or more finishing coats until the desired coverage and colour depth are achieved. Allow adequate drying time between coats and before exposure to weather or heavy use.

What to consider before purchase

• Colour change: mahogany pigment will alter the natural wood tone; test on a small area first.
• Coverage: depends on wood porosity and number of coats required.
• Surface condition: heavily decayed or wet wood requires repair and drying before treatment.
• Intended finish: film-forming coating gives a pigmented layer rather than a fully transparent effect.

Usage recommendations

For best results, apply at temperatures recommended by the manufacturer and avoid treatment in direct rain or extreme humidity. Regular inspection and maintenance coats extend protection — reapply when the coating shows signs of wear or fading. Store the container tightly closed in a cool, dry place away from frost and ignition sources.
