The grey flour is a stone flour or filler. You can use it to make your own filler and create interesting structures and surfaces. Let your passion for experimentation run wild.
Make your own filler with acrylic glue
The products to be used are acrylic glue and grey stone powder in a ratio of 1:3. Our acrylic glue has a creamy consistency, extremely high adhesive strength and is snow white (but dries transparent). This means that the colour of the grey stone powder is retained. Other fillers such as ash, sand, etc. can also be used for this.
Take a tall container with a smooth side. Fill the container with acrylic glue and gradually add the grey flour. This mixture can be mixed very well with a spatula or a painting knife. Use the spatula to smooth the mixture onto the side of your container. You can mix the filler a little thinner or thicker as needed. It depends on how you want to express the filler on your work of art.
Homemade filler is often easier to work with and produces a nicer result, as ready-made fillers often have a plastic-like surface and no longer absorb color. They then appear like a foreign body in the picture.
Make your own filler with chalk paint
Instead of acrylic glue, you can also use white chalk paint. This has the advantage that the high chalk content in the paint means that cracks will appear more often after drying. The cracking can be increased by applying heat. You can use a conventional hair dryer for this. The thicker the filler (chalk paint and gray powder) is applied, the more cracks will appear.
tip for applying the filler with grey flour
Apply the filler in different thicknesses to achieve different effects. Contrasts always look good in a picture. Pay attention to the composition of the picture.
Apply grey flour loosely
A filler such as grey flour always needs a binding agent. Sprinkle this onto the still wet paint or your damp surface. Spray it again with water or gently brush it over with a spatula. Sweep away the loose material after it has dried and save it for your next work. Everything that sticks to the canvas is the basis for further processing. If you want, fix this area with a pastel fixative spray, but this is not absolutely necessary. If some grey flour comes off, it will mix again with the newly applied layer of paint. This technique is also often used when painting landscapes. Stone structures and landscape levels look very impressive with this technique.
