Grounds & Varnishes
Surface Preps are products used to prepare a surface for painting. Effective grounds should have good adhesion to the painting surface. They should be flexible, have suitable “tooth” for overpainting and create a good sealing barrier between the painting surface and subsequent layers of paint.
A water-based acrylic emulsion, which can be used straight from the bottle or thinned with water 1:1 to seal most surfaces. Atelier Binder Medium can be used as a sizing on canvas or cotton duck to seal the surface and prevent absorption of paint into the fabric. Mix with paint to dilute colour without losing intensity. Use neat between dry paint layers to seal or mix with Atelier Interactive for fast drying acrylic techniques.
A flexible acrylic ground with a high grit content designed to provide a stable white surface on which to paint. Atelier Gesso may be used directly from the container for all over thick textural effects.
Has a thinner consistency which spreads more easily for a smoother painting surface.
Free Flow Gesso
It is always a good idea to prepare any “pre-prepared” canvas with a good Gesso before you start a painting. This new range of Free Flow Gessos has a particularly easy to spread fluid consistency. The surface is gritty when the Gesso dries and for a smoother finish it can be sandpapered but users might like to consider the gritty tooth unmodified. It is good for mixed media and easier to apply than less fluid Gessos.
The colours now available in the Free Flow Gesso are: Unbleached Titanium, Raw Sienna, Light Red Ochre, Indian Red Oxide, Carbon Black.
Final Varnishes are used to protect the completed painting and to adjust the surface quality of the paint. If your painting is too shiny or matte, you can correct the surface by choosing the appropriate varnish.
Chroma Solvent Finishing Varnishes
Solvent based, non-yellowing strippable varnishes which means paintings can be cleaned more easily at a later date by swabbing with mineral turps. Chroma Solvent Varnishes are available in Satin, Gloss and Invisible. Invisible Varnish provides a protective coating and does not alter the surface quality of a painting.
Matte, Satin & Gloss Varnishes
Low viscosity products made from hard acrylic emulsion. Can be used as an over-varnish for Atelier Interactive and other traditional acrylic paints. To use as a varnish over an Interactive painting, seal with 2 coats of Fast Medium/Fixer before varnishing. They are non-removable, however they can be over painted. The acrylic varnish may be mixed with acrylics as a low viscosity medium to change the sheen levels or to dilute for glazing. Atelier Interactive will dry fast and waterproof if used in this way.
