They can be used to repair rotting timber window sills and frames, or sash windows. They can be stained or tinted to match the existing wood, and then painted. This guide will help you choose the best type of filler to suit your needs.

Water-based wood-fillers tend to dry faster than solvent-based ones, and are simpler to remove because they do not require acetone.
Another option is to use regular acrylic latex caulk to fill the gaps between the frame of the window and the wall opening. This will work fine and is very easy to apply and will accept the majority of paints. It is essential to check the frame for rot before applying before sanding it, as excessive sanding can make the gap too large and the window vulnerable to leaks.

This filler can be sanded, or carved when it's hard, giving you greater control over the final outcome.

This is an extremely efficient method of splicing in damaged timber and is particularly useful in areas where it is cheaper to splice instead of replace the entire sill. This kind of repair is also a great option for replacing a small section of timber that is decayed but is not affecting the surrounding timbers and isn't in need of major replacement.
When performing repairs to a splice, it is essential to use high-quality timber which will hold the cement in place and withstand any movement of the splice. It is essential to remove all emulsions from the splice and to avoid using excessive amounts of film cement which can cause it to leak and damage the surrounding lining. It is recommended, once the splice has been completed, to tape the edges to hold the repair in the correct position. Then, apply the film adhesive starting from the center outwards (fig. 11.1 iv).
