Wood Impregnator V33 Classique (Scandinavia) — protective wood treatment, interior/exterior use

V33 Classique (Scandinavia) wood impregnator is a protective treatment formulated for both interior and exterior timber. It penetrates into wood fibres to reduce moisture absorption and slow biological deterioration, providing a stable base for subsequent finishes. Suitable for untreated or previously coated softwoods and hardwoods, the product is intended for use on decks, fences, cladding, joinery and garden furniture where improved moisture resistance and substrate preservation are needed.

Advantages

The impregnator delivers deep penetration that helps limit water ingress and reduce swelling and shrinkage cycles in timber. It creates an effective preparatory layer for paints, stains or varnishes without altering the natural texture of the wood. The formulation improves resistance to rot and surface degradation while maintaining breathability, allowing wood to release trapped moisture gradually. Easy to apply by brush, roller or low-pressure sprayer, it supports long-term maintenance programmes for wooden elements.

Suitable for

• External decking and terraces
• Garden fences and gates
• Wooden cladding and siding
• Joinery, frames and doors
• Outdoor furniture and benches

Key specifications

• Application: interior and exterior protective impregnation
• Penetration: formulated for deep substrate absorption
• Finish compatibility: suitable as a base for paints, stains and varnishes
• Material compatibility: softwoods and hardwoods, untreated or previously coated
• Performance: reduces moisture uptake and helps limit biological degradation
• Application methods: brush, roller or low-pressure spray

How to use

Ensure the wood surface is clean, dry and free of dust, grease, mildew or flaking coatings before application. Stir the product well and apply evenly following the grain using a brush, roller or low-pressure sprayer. Allow sufficient penetration time and, if required, apply a second coat once the first coat has been absorbed and is touch-dry. After impregnation, allow the surface to dry fully before applying paints, stains or varnishes according to the coating manufacturer’s instructions.

Usage recommendations

For best results, test the product on a small inconspicuous area to confirm absorption and appearance. Maintain good ventilation during application and drying. Do not apply in temperatures below the manufacturer’s recommended minimum or in direct rain; protect newly treated surfaces from moisture until fully dry. Regular inspection and reapplication according to exposure conditions will extend the life of wooden elements.
