Rublev Colours Underpainting Transparent Base

Not all painters use underpainting; it seems that those who do want it to dry fast so they can begin colouring in the overpainting. Underpainting Lead White and Transparent Base can be used with your standard oil colours and have them dry blindingly fast—usually within a few hours. Add the Underpainting Lead White or Transparent Base—from one third to one half—to your oil colour and your underpainting dries quickly to a matte sheen. Add less for slower drying.

Use Underpainting Transparent Base in the underlayers of an oil painting or as a fast-drying medium in alla prima (direct) painting.

Directions

Add Underpainting Transparent Base directly to your paint, mixing thoroughly 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 the Underpainting Transparent Base with mineral spirits and/or linseed oil.
