Sadolin Stainable Woodfiller - 350 ML

Sadolin Stainable Wood Filler is the go-to solution for wood imperfections, especially corner work and holes up to 50mm deep, such as knots. Packaged in a 350ml container containing base and hardener, it's specially crafted to accept wood stains, ensuring a seamless match to your wood or woodstain.

For smaller repairs, consider Sadolin Wood Filler.

Before filling, ensure timber surfaces are appropriately prepared, clean, stable, and dry, with a moisture content not exceeding 18%.

• Remove any existing paints, stains, or varnishes completely from the area to be filled.
• Take precautions when preparing pre-1960s painted surfaces due to potential lead content.
• Remove decayed timber and cut back 25mm into sound material, making necessary repairs.
• Consider splicing in new timber sections for large areas.
• Treat the area to be repaired (and any new timber) with Sadolin Quick Drying Wood Preserver or Sadolin Wood Preserver, allowing it to fully dry before filling with Sadolin Stainable Wood Filler.
• Timber treated with Sadolin Quick Drying Wood Preserver can be repaired after 24 hours, while Sadolin Wood Preserver requires 72 hours drying time.
• For enhanced adhesion, insert clean, non-ferrous nails or screws just below the level of the finished surface and fill with Sadolin Stainable Wood Filler.

Note: Failure to provide a suitable substrate may compromise adhesion and performance. Following the manufacturer's recommendations and sanding the repaired area flush can yield perfect results.

Before starting any project, conduct a small test area and strictly adhere to the manufacturer's instructions on the container.

Avoid application in rainy conditions or when air/substrate temperatures are below 8C or the relative humidity exceeds 80% during application or drying periods. Protect from frost and rain until dry to maintain the filler's curing, visual quality, and durability.

Sadolin Stainable Wood Filler comes in two parts: a can of filler and a tube of hardener. Both components must be combined for use.

• Place filler, approximately the size of a golf ball, onto a clean, non-porous board. Squeeze about 3.5cm of hardener from the tube and thoroughly mix with the filler until a consistent colour is achieved.
• Once mixed, the workable life is around 5 minutes at 20C. At higher temperatures, this time will be reduced, so only mix a sufficient amount for immediate use.
• Apply the mixed material with a plastic spatula or similar implement, leaving it slightly raised above the surface to allow for subsequent machining or sanding.
• Ensure thorough application by forcing the filler into the area to be filled, eliminating any trapped air and ensuring good contact with the timber.
• To prevent a 'halo' effect on bare wood and facilitate isolation of the working area, use masking tape to protect the surrounding area during the fill. Remove the tape immediately after completing the fill while the product is still workable.
• For deep fills, consider building up the product in layers.
• Remove excess filler after the initial 5-minute curing period using a sharp chisel.
• Allow a minimum of 15 minutes before sanding, depending on the thickness of the filler applied.
• Coatings can be applied after 30 minutes drying time when the filler achieves full hardness.
• Lightly abrade the surface of the filler to enhance the uptake of wood stains or dyes.

Immediately remove or scrape off excess filler from spatulas and filling knives, and clean with cellulose thinners.

Once the wood filler is dry, it can be coated with a suitable top coat from the Sadolin range.

When overcoating with translucent products, the final appearance depends on factors such as timber species, absorbency, and existing coatings.

For darker timbers like walnut, mahogany, or teak, or if surrounding timber is stained, apply a little stain to the filled area with an artist's brush to match the colour before re-staining or varnishing the entire surface. Some timbers may absorb differently than the filler, requiring multiple stain applications for desired results.

Always conduct a test application for accurate colour matching. Ensure the colour match between the substrate and filler is satisfactory before applying clear or translucent finishing coats.

In exterior locations, maintain the protective finish as needed. Leaving the timber unprotected may lead to excessive movement, potentially compromising the bond between the timber and filler.
