Wood preservative impregnation primer Drewnochron Impregnat Grunt 2.5L

Drewnochron Impregnat Grunt 2.5L is a wood preservative and primer formulated to penetrate timber and improve the durability of subsequent coatings. Designed for both exterior and interior wooden surfaces, this 2.5-liter primer protects against biological degradation while creating a stable base that enhances adhesion of paints and stains. The product is suitable for preparation of new or weathered wood before finishing.

Advantages

This wood preservative primer penetrates deeply into the substrate to reduce the risk of rot, mold and insect damage. It evens out the absorbency of wood, which helps to prevent uneven drying and blotchy final finishes. As a primer, it improves adhesion of paints and stains, extending the performance of topcoats and reducing the need for frequent maintenance. The water-based formulation allows for easier application and cleaning.

Suitable for

• Exterior timber elements such as fences, posts and cladding
• Garden furniture and outdoor wooden structures
• Interior woodwork where protection and priming are required
• Preparation of new or previously painted/stained wooden surfaces before finishing

How to use

Ensure surfaces are clean, dry and free of dust, grease, loose paint or rot. Stir the product thoroughly before use. Apply evenly with a brush, roller or low-pressure spray, allowing the primer to penetrate the wood. For highly absorbent or weathered wood, a second coat may be applied after the first coat has dried. Allow the primer to dry fully before applying paint, stain or other topcoats, following the topcoat manufacturer's instructions.

Usage recommendations

Use on well-ventilated areas and protect nearby plants and materials from overspray. Store and apply at temperatures recommended on the product label. Test adhesion and appearance on a small inconspicuous area before full application.
