Wood stain for parquet – professional finish

Special Joint Stain: the art of invisible joints in parquet

The Special Joint Stain is designed for professionals and discerning DIY enthusiasts who wish to perfectly blend new and old planks on a repaired or renovated parquet floor. Ideal for localised repairs, it erases visible boundaries between existing and replaced wood, whilst enhancing the natural grain and texture of the wood. Compatible with all finishes (Blanchon, sealants, oils, waxes), it offers a practical and quick solution on site.

A uniform and natural finish

Unlike traditional stains, the Special Joint Stain:Key benefits:

• Penetrates quickly without blocking the wood’s pores.
• Allows for direct application of the finish without an intermediate step.
• Offers adjustable coverage to reveal the wood’s structure rather than mask it.

• Immediate blending between old and new boards.
• Enhances the natural grain without a ‘painted’ effect ".
• Can be overcoated with all finishes (water-based, solvent-based, oils, waxes).
• Fast drying (20 to 30 minutes).
• Odourless formulation, suitable for occupied interiors.

Instructions for use and professional advice

Preparation and application

1. Lightly sand the board to be joined (120–150 grit) and remove dust.
2. Carry out a colour test on a scrap piece or hidden area.
3. Apply the product precisely using a fine brush, pad or microfibre cloth, allowing it to extend slightly onto the adjacent boards.
4. Wipe off any excess after 2 to 5 minutes to even out the colour.
5. Leave to dry for 20 to 30 minutes before applying the chosen finish.
6. Adjust if necessary with a concentrate to mimic the shades of weathered wood.
