The technical properties of acrylic primers
As a ground for acrylic paint, gesso can be coloured with acrylic paint in any proportion.
The fact that Gesso is visible on the reverse side is technically not a problem. It has to do with whether a fabric is tightly or loosely woven. In the latter case, it is more likely to occur. It is not so nice to see and can easily be remedied by first applying a layer of Amsterdam Acrylic Binder 005 before applying the Gesso. This seals the gaps in the canvas. Acrylic binder is completely transparent after drying.
Modelling paste can be seen as a thick Gesso. The paste can be applied under the paint to create relief but can also be mixed with acrylic paint in any proportion.
If a plastic surface is related in molecular composition to the paint's binder, adhesion is possible. Nevertheless, it is advisable to first treat non-absorbent grounds with an adhesive primer suitable for that material (industrial product) and then prepare the paint with Amsterdam gesso for good adhesion.
Technically, acrylic paint can be used to paint directly on a wall. However, due to the absorption of, for example, stone, plaster and stucco, a good preparation will give a better result because, with the paint, the intensity of the colour will also be absorbed, as it were, by the wall. If the colour of the wall is to be part of the artwork, suction can be reduced with Amsterdam Acrylic Binder 005 (Acrylic Binder is a pure unpigmented acrylic dispersion that dries colourless and transparent). If a white surface is desired, the wall can be prepared as follows: brush with thinned Amsterdam Acrylic Binder ± 20% water is sufficient dilution, for strongly absorbent surfaces apply pure. Apply two layers of pure Amsterdam Gesso, let dry for 24 hours in between.
Acrylic binder produces a more closed paint layer. That is why you get an even better result with Amsterdam Gesso. Amsterdam Gesso is available in three colours: transparent, white and black.
