LeFranc 12 Hour Size reaches tack in 12-14 hours depending on film thickness, temperature and humidity. After reaching the proper gilding tack, it will remain open for gilding with genuine gold leaf for 8-12 hours. Allow the gilded surface to cure one month before sealing or glazing. Always stir LeFranc size before use. The driers in LeFranc size settle to the bottom of the container and must be stirred to produce a blended product.
Oil sizes are ready to gild when you tap your knuckle against the surface without disturbing the size or coming away with residue. Oil sizes may be thinned up to 10 percent with mineral spirits. If thinned, the drying time may be reduced. A soft hair brush is a must as it will produce a smooth even surface. Brushes are best cleaned with mineral spirits.
Porous surfaces should be sealed to create as smooth surface for gilding. Shellac is recommended for sealing gilded surfaces on interior work.
