Wood Impregnator V33 Classique — Colorless (transparent) wood preservative

V33 Classique Wood Impregnator — Colorless (transparent) wood preservative is formulated to protect raw or previously treated timber against biological degradation and weathering. This transparent preservative penetrates into the wood structure to limit moisture uptake, inhibit rot, mold and insect attack, and prepare surfaces for subsequent finishing coats. It is suitable for both interior and exterior wooden elements such as cladding, fences, garden furniture and joinery where a neutral, non-pigmented protection is required prior to painting, staining or varnishing.

Advantages

The product provides deep penetration without altering the natural colour or grain of the wood, ensuring a near-invisible first layer of protection. It reduces water absorption and increases the durability of timber by limiting conditions that promote fungal decay and insect infestation. Because it is colourless and transparent, it is compatible with a wide range of finishing systems and does not interfere with subsequent paint, stain or varnish adhesion when applied according to instructions.

Suitable for

• Exterior cladding and sidings
• Garden furniture, pergolas and fences
• Interior joinery and raw timber elements
• Preparation before painting, staining or varnishing

Key specifications

• Finish: colourless / transparent
• Protection: reduces moisture uptake and inhibits rot, mold and insect attack
• Application: brush, roller or low-pressure spray
• Suitable substrates: raw or previously treated softwood and hardwood
• Use: interior and exterior timber

How to use

Ensure the wooden surface is clean, dry and free from dust, grease or flaking coatings. Apply the impregnator evenly by brush, roller or low-pressure spray, working along the grain and allowing the product to penetrate. For highly absorbent wood, apply a second coat after the first has been absorbed. Allow sufficient drying time before sanding lightly if required and then proceed with your chosen topcoat system. Follow ventilation and safety instructions on the product label during application.

Usage recommendations

Apply on frost-free, dry days and avoid application in direct rain or strong sunlight. Test on a small, inconspicuous area before large-scale application to confirm compatibility with subsequent finishes. Store in a cool, well-ventilated place and keep out of reach of children.
