Product Information
Full details
The Daler-Rowney Ox Gall Solution is an essential additive for watercolourists and mixed-media artists who struggle with paint beading or uneven application on difficult surfaces. By functioning as a natural wetting agent, it significantly improves flow, levels washes, and enhances paint adhesion on hard-sized or greasy surfaces. While it is an invaluable tool for smoothing out your workflow, users should be aware that it must be used sparingly to avoid making the paint film too water-soluble or difficult to lift during later painting stages.

FAQs
Can I use this with gouache?
Yes, Daler-Rowney Ox Gall is perfectly compatible with both watercolours and gouache.
How much should I add to my water?
A few drops are usually sufficient. Start with 1-2 drops and increase only if you continue to see beading on the paper.
Does this product change the lightfastness of my paint?
No, Ox Gall is a wetting agent and does not alter the chemical lightfastness of your pigments.
Is this product vegan or animal-derived?
As the name implies, Ox Gall is traditionally derived from bovine sources. Please contact the manufacturer for specific ingredient sourcing if this is a concern.
Will it make my painting permanent?
No, it is a wetting agent, not a binder or a varnish. It will remain water-soluble once dry.
Troubleshooting
Solution appears cloudy or hazy in the bottle
This is a natural occurrence; simply shake the bottle well to restore the solution to its optimal state.
Paint is not adhering even after adding the solution
Ensure the paper surface is not coated in excessive oils; try a light, clean water wash first, then add slightly more Ox Gall to your pigment mix.
Paint wash is too watery or loses intensity
You may have added too much Ox Gall. Use fewer drops in your mixing water to maintain the pigment's concentration.

Setup, Compatibility & Care
To begin using the solution, simply fill your water jar as usual and add two or three drops of the Ox Gall directly into the water. Stir gently. Because it is highly concentrated, start with a minimal amount and add more only if necessary.
Compatibility:
- Fully compatible with all water-based media.
- Best results when paired with the Daler-Rowney Aquafine range.
Care and Storage:
- Store the bottle upright in a cool, dry place away from direct sunlight.
- If you notice the solution appearing hazy or cloudy in the bottle, this is normal for a natural wetting agent. Simply shake the bottle vigorously to restore it to its active, consistent state before use.
