Matte medium acrylic paint additive.
Shake before use. Mix 5% Duller with The Footwear Care acrylic paint to give more it of a matte look. Adjust the amount of Duller to suit your requirements. Apply paint with thin even coats. Test on an unseen area before use. We advise not to mix over 10% of Duller as it may overpower the acrylic paint by leaving white streaks.
