How much will the open time be altered by the retarder?

How much retarder can I add to the paint?
You can add between 10-30% of retarder which will also improve flow of your paint and reduce brush marks. Use maximum 1 drop of retarder per 2 drops of paint (30%).
Paint is drying too slow I want to paint another layer!
Use hair drier to speed up the process. Just remember to keep up a distance of 20-30 cm and use low setting.
Is the retarder compatible with my paint?

Can I use this product as an airbrush extender so as to mitigate tip drying?
Yes, you can add some retarder along your usual paint thinner to slow drying time and make airbrushing more comfortable but Slow-Mo Retarders were formulated with painting with a brush in mind (brush icon on the label). For best results please use our newly formulated, airbrush-dedicated Slow-Mo Extender which is a concentrated product with twice the potency (airbrush icon on the label).
