Winsor & Newton's Artists' Acrylic modelling paste is lightweight and flexible so it doesn't shrink or crack. It thickens the consistency of the colour, building body and structure and accentuating texture, brush marks and palette knife marks. It also increases the opacity of the colour. It is ideal for carving, sanding and creating extreme textures. It can be used to easily and quickly build up depth in layers, and either overpainted when dry or mixed with colour. Due to the high level of solids in the paste which gives its thick structure, it is opaque and therefore may lighten certain colours. It provides an even matt finish.
I bought this paste for my project where I needed to achieve a 3D texture on the paper. The layer of the paste dried in couple of hours which is pretty fast and I could add some colour on top. Enjoyed using it! Alina Girdhar (Ashby-de-la-Zouch, UK) on 25 Jun 2016
Great for applying an interesting texture. Firms up overnight. John McBrien (Worthing, United Kingdom) on 31 Jan 2018
I use this to turn Windsor and Newton canvas boards from medium to fine surface. I buy the W&N boards because the card the canvas is mounted on is heavier and stays straighter than others I have purchased.
I also use modelling paste with my paint but this particular product has a lot of additive in it, presumably to make it lightweight, and that makes it feel gritty for painting. So I use the Galeria modelling paste to mix with paint. Peter Colby (Liverpool, United Kingdom) on 1 Mar 2019
