Product Description
Underpainting Transparent Base is a fast-drying, alkyd paste medium, similar to Velázquez Medium in handling properties, but much faster drying. This alkyd paste medium consists of finely ground calcite (ground calcium carbonate) and wollastonite in an alkyd vehicle with mineral spirits. Add Underpainting Transparent Base to any oil color to extend it for fast drying underpaintings. The paint layer usually dries within an hour or two. Adding it to oil colors makes them slightly transparent allowing greater control over tints without using whites. Dries to a matte finish. Underpainting Transparent Base does not contain driers.APPLICATIONSUse Underpainting Transparent Base in the underlayers of a painting or as a medium in alla prima (direct) painting.
Not all painters use an underpainting, it seems that those who do want it to dry fast so they can begin coloring in the overpainting. Natural Pigments has a simple solution that does not require buying a whole new set of colors just for the underpainting. Introducing two new products: Underpainting Lead White and Transparent Base. With either or both products, you can use any of your standard oil colors and have them dry blindly fast-usually within an hour or so. Add the Underpainting Lead White or Transparent Base-from one third to one half-to your oil color and your underpainting dries quickly to a matte sheen. Add less for slower drying.
DIRECTIONSAdd Underpainting Transparent Base directly to paint, mixing well on the palette. Do not apply Underpainting Transparent Base over slower drying oil paint, as this may lead to cracking or wrinkling of the layer. You can thin Underpainting Transparent Base with mineral spirits and/or linseed oil.
