Thixatropic paints must not be stirred; unlike most other paints they do not settle in the same way. When using liquid paints. However, always stir them thoroughly first so that the particles settled in the bottom of the tin are distributed evenly.
If using a paint-stirring attachment on an electric drill, use it at a slow speed and remember to switch the drill on and off while the stirrer is still immersed in the paint. If stirring paint by hand. Use a length of clean hardwood batten, turning it in a circular lifting motion. Make sure, too, that the stirring-stick is pushed well down into the edge around the bottom of the tin.
When finished, replace the lid firmly and stand the tin upside-down. The next time the paint is needed the skin will be at the bottom of the tin.
