Sadolin Wood Filler

Sadolin Wood Filler has been designed for small repairs and should not be applied at depths in excess of 5mm. Quick and easy to apply, provides excellent adhesion. Made from nitro-cellulose resin.

• For larger holes, consider an alternative filler such as Sadolin Stainable Wood Filler

Timber surfaces must be suitably prepared, clean, sound and dry. The moisture content should not exceed 18% prior to filling.

1. Any existing paints, stains or varnishes must be totally removed from the area to be filled
2. All timber exhibiting signs of decay must be removed and cut back 25mm into sound material, and made good
3. Smooth areas should be slightly abraded to ensure a good key is obtained
4. When filling larger areas, consideration should be given to splicing in new timber sections
5. After cutting back, treat the area to be repaired (and any new timber) with Sadolin Quick Drying Wood Preserver and allow to dry fully prior to repairing with Sadolin Wood Filler
6. Timber treated with Sadolin Quick Drying Wood Preserver can be repaired after 24 hours

Please Note: Failure to provide a suitable substrate may result in poor adhesion and performance of the repair. When used in accordance with the manufacturer's recommendations, and the repaired area is sanded flush, excellent results are achievable.

Applying Sadolin Wood Filler

Always do a small test area before beginning any project and follow the manufacturer's instructions on the container at all times. Sadolin Wood Filler is supplied ready for use.

Conditions

Do not apply if there is a risk of rain, or when air / substrate temperatures are below 8°C or the relative humidity is above 80% during application or drying periods. Protect from frost and rain until dry. Failure to meet these requirements may adversely affect the curing, visual quality and durability of the filler. The filler remains workable for up to 2 minutes at a temperature of 20°C.

Application

1. The wood filler should be applied with a plastic spatula, filling knife or similar implement and left slightly 'proud' of the surface to allow for subsequent machining or sanding
2. Apply the filler carefully to ensure all air is displaced and good contact is made between the filler and the timber
3. Do not smear the filler around the area to be filled as this will affect the absorbency of the timber and may result in a poor visual appearance when subsequently stained or varnished
4. Consider using masking tape to protect surrounding areas if practical - remove whilst product is still workable
5. The filler can be sanded after approximately 30 minutes and coated after 2 hours
6. Carefully sand the filler flush to the timber surface using a medium grade abrasive paper
7. Remove any sanding dust with a vacuum cleaner

Please Note: After storage a small amount of liquid may form on the surface of the material. This can easily be remixed into the material by stirring and does not affect performance.

Always choose a colour of filler that is similar to the colour of the substrate (i.e. either that of the timber or of the stained timber that is to be filled). Alternatively choose Sadolin Stainable Wood Filler and use with your chosen wood stain or dye.

Cleaning Equipment

Filling knives and other equipment should be cleaned with warm water before the product hardens.

Sadolin Wood Filler can be over-coated with most types of interior and exterior timber coating systems. When over-coating with translucent products, as with all such products, the final appearance is dependent on a number of factors, including the timber species, the relative absorbency of the timber and the filler, and the presence of any existing coating.

If the timber that is filled is much darker than the filler, or if the surrounding timber has been stained, apply a little stain to the filled surface using an artist's brush to bring it to a similar colour before coating the whole surface. More permeable timbers will absorb stain to a greater extent than the filler and 2 or 3 applications of stain to the filled area may be required to achieve the desired result.

Always carry out a test application, especially when accurate colour matching is important. It is essential to ensure that the colour match between the substrate and filler is acceptable in terms of colour, density and workmanship before over-coating with clear or translucent finishing coats.

In exterior locations the decorative / protective finish should be maintained in the usual way. If the timber is left unprotected it will move excessively and this may result in a breakdown of the bond between the timber and filler.
