To thin water-based oil paint, add a few drops of linseed oil at a time until you reach your desired consistency.
Understanding Water-Based Oil Paints
Water-based oil paints, also known as water-mixable oil paints, are designed to be thinned and cleaned with water, unlike traditional oil paints that require solvents. However, sometimes you might want to adjust the consistency further for specific techniques.
Thinning Methods
While water is the primary thinner, other options can fine-tune the paint's properties:
-
Linseed Oil: Adding a tiny amount (1-2 drops at a time) of linseed oil can improve the flow and blendability of the paint. This is particularly useful if the paint feels too thick or sticky straight from the tube. Be careful not to add too much, as it can make the paint more transparent and increase drying time.
-
Water: This is the most common and recommended thinner. It's readily available and keeps the paint water-mixable. Add small amounts of water gradually, mixing thoroughly, until you achieve the desired consistency.
-
Water-Mixable Oil Painting Mediums: Many brands offer mediums specifically designed for water-mixable oils. These can enhance flow, transparency, gloss, or drying time, depending on the specific medium. Always follow the manufacturer's instructions.
Precautions When Thinning
- Thin Sparingly: Over-thinning can cause the paint to become weak, lose its color intensity, and not adhere properly to the canvas.
- Mix Thoroughly: Ensure that any thinner you add is fully incorporated into the paint before applying it.
- Consider the Effect on Drying Time: Adding excessive amounts of linseed oil can slow down the drying process.
- Follow Manufacturer's Recommendations: Always consult the paint manufacturer's instructions for specific guidelines on thinning their products.
Summary
Water-based oil paints are typically thinned with water. For minor adjustments to flow and consistency, a very small amount of linseed oil can be added. Always thin sparingly and mix thoroughly to avoid compromising the paint's quality and adhesion.
