Glue paint mix
125g rabbitglue powder
Heat the water to 40 °C, boil slowly until the gluepowder is dissolved. Water must not boil. This is a so called 12% mix that can be used as a glue for new wooden surfaces. When fixing old furniture the mix should be a 5% mix so that the edges of the fix won’t be too rough and end up breaking the furniture. You can add a desired amount of chalk powder to the mix and add colors by using color pigments, Glue or gluepaint should be used straight from the boiler since it hardens once it cools. It dries fast so it requires quick work. The left over glue can be stored in the fridge for about a week. It is easy to heat up for new usage.
