3-in-1 Medium

The Gamblin 3-in-1 Medium is a verstile oil medium that is intended to provide support at every stage of painting. It is the leanest oil painting medium that Gamblin offers and is recommended for everything from underpainting, to preparing panels for oil painting, as well oiling out between layers and before varnishing. The 3-in-1 Medium also restores saturation and depth of color in dry paintings.

Underpainting

• 3-in-1 is designed to be used for fluid washes and tonal layers of color. You can use as much (or as little) 3-in-1 as you prefer with oil colors to extend flow and increase transparency. 3-in-1 does not impart high-gloss and dries to a subtle, semi-gloss/satin finish.
• When used with iron oxide underpainting colors like Raw Umber, thin washes and tonal layers of colors typically dry to the touch within approximately 24-48 hours. Cold temperatures, increased humidity and using colors not commonly associated with underpainting can prolong dry time rates. If one wants an even faster dry time result for their underpainting, a 1:1 mixture of Galkyd + Gamsol is suggested.
• 3-in-1 is compatible with the entire Gamblin range of oil painting mediums and other brands of painting medium.

Panel Prep

• 3-in-1 is useful for preparing wood panels and other substrates for oil painting and before application of Gamblin Oil Ground. The main purpose of this step is to stop the panel from taking on moisture, which helps prevent warping over time.
• In comparison to utilizing PVA Size for prepping, 3-in-1 is preferable for preparing panel substrates for oil painting or Oil Ground as the chemical bonding between 3-in-1 and Oil ground makes is superior for panel preparation.

Oiling-Out

• Oil paintings sometimes develop an uneven variation where certain areas may appear dull while other areas appear more glossy. Oiling-out with 3-in-1 is an easy way to fix this.
• Oiling out, brushing on and wiping off oil medium, may be used throughout the painting process and prior to varnishing.
