Leaf & Foil Size is a clear no VOC water based medium with a long open time to be used for all foil and leafing projects. Once applied it provides a flawless tacky surface for the application of metallic leafing and foils.
Leaf & Foil Size only needs one pass and has an easy release. It will not discolor your treated surface and has been formulated for a smooth and easy application. Size can be rolled or brushed on, will tack up within 45 – 60 minutes (it will take longer on a wall) and will remain tacky until the Clear Topcoat is applied.
