Make effective and durable wood spatula yourself

Finished wood putty is usually expensive and in many cases brings no decisive advantage over the self-manufacture. Some special manufacturers offer bindable mixed bases, which are then produced by enriching their own wood putty. As a binder, other substances such as paint, glue and glue or shellac can serve.

Binder and filler

Aside from the price, making a wood spatula yourself can make for a more precise color match between the wood surface and backfilling. As an obvious filler grinding and saw dust is used, which is obtained from the workpiece to be spiked. Unlike the possible color variations with external fillers, the putty will hit the color perfectly after drying.

As a binder is transparent wood glue. White glue "dilutes" the color intensity of the mixed filler at the latest after drying. It must be considered whether the binder used picks up stain or grease if the wood is to be treated with one of these substances. Normal wood glue is not suitable in these cases.

Shellac, colorless polyurethane-based adhesive or nitro lacquer are used as alternative binders. In principle, self-mixing with synthetic resin are possible, but require disproportionately large effort and technical equipment due to heating need and health hazardous vapors.

When wood is spread on a floor, attention should be paid to the load capacity. Most proprietary blends have no stretchability or elasticity. This can lead to bursting of the fillings on heavily used wood surfaces.

Mix creamy and homogeneous mixture

When making the self-leveling compound from the binder while mixing a uniform creamy mass is mixed. The sawdust is stirred into the binder piece by piece. The technique should be that of a roux in the saucepan.

The sawdust is previously sifted through a fine sieve to remove coarse matter and debris. As a container and as a stirring tool, a plastic or rubber bowl and a plastic spatula should be used. Metal can influence the properties and color of the putty by chemical reaction.

Tips & Tricks

Note the relatively short pot life of your self-applied spatula. Consume it as soon as possible. You can gain a few minutes of processability by sealing in an airtight container.
