Wood protection impregnation SADOLIN Classic HP clear 2.5 L

SADOLIN Classic HP clear 2.5 L is a clear wood impregnation for surface protection that soaks into timber to provide basic moisture and wear resistance while keeping the natural grain visible. Designed as a preparatory treatment, this pore-forming impregnation improves the substrate for subsequent finishing coats and is suitable for both interior and exterior wood surfaces where a transparent base is required before painting or varnishing.

Advantages

The impregnation penetrates the wood structure to reduce moisture uptake and slow surface deterioration without forming a film that hides the texture. Its clear formulation maintains the natural appearance of timber and enhances adhesion of paints and varnishes applied afterwards. The product is formulated to be compatible with common finish systems and to support long-term durability when followed by appropriate topcoats.

Suitable for

• Interior wooden panels, doors and trim requiring a clear base treatment
• Exterior cladding, fences and garden wood prepared for painting or varnishing
• New or previously untreated softwood and hardwood surfaces
• Areas where pore-forming protection is preferred before applying decorative or protective topcoats

Key specifications

• Type: clear, pore-forming wood impregnation for surface protection
• Volume: 2.5 litres
• Application: brush, roller or spray
• Finish effect: transparent, preserves natural wood grain
• Use: suitable for interior and exterior wood substrates
• Purpose: reduces moisture penetration and improves adhesion of subsequent coatings

How to use

Ensure the wood surface is clean, dry and free of dust, grease or loose material before application. Stir the product thoroughly and apply evenly using a brush, roller or appropriate spray equipment, working along the grain. Allow sufficient penetration time and wipe off excess if necessary. For porous or heavily absorbent wood, a second coat may be applied after the first coat has been absorbed and surface is touch-dry. After impregnation has dried, apply compatible paints or varnishes following their own instructions for best performance.

Usage recommendations

Apply at temperatures recommended by the manufacturer, avoid application in direct rain or strong sunlight, and use suitable personal protective equipment during handling. Test on a small inconspicuous area if uncertain about compatibility with the chosen topcoat or wood species.
