Our Extender is great for those who want a longer open time with the paint, to help minimize the look of brush strokes and to extend drying time.
Painting in a dry climate or a space with low humidity? You may find your paint dries too fast. Buy yourself time with our uniquely formulated non-toxic extender – simply add it to the paint and you’ll have more time to brush back and forth to get the look you’re after!
The recommended ratio of 15 mL per pint (500 mL) of paint.
Using too much of this product will increase drying time substantially, but also increases cure time. Add a maximum of 10% of the original paint volume.
