3 brush sizes offer the flexibility to cover large and small areas, depending on the size of your project. Use your chosen brush to apply a generous layer of adhesive, 3 mm thick, onto your desired surface. Allow to dry 1-2 hours or until adhesive dries clear. When dry, adhesive will be tacky to the touch and form a strong bond with the dotz. Clean up with mild soap and cold water after each dotting session. 3 pc.
