How do you apply gesso?

Its to coat with a substance, Generally with metal leaf. To gild; make sure your substrate is clean and dry "Free of contaminates", apply sizing (glue)allow to set up for 30 to 60 minutes,it must be tacky not gooy,then take a very fine brush and apply the leaf and brush lightly over the leaf, once your gilded area is covered lay wax paper over gilded area and burnish lightly. I recommend using only gilding size and sealer. You can pick-up the "Right" supplies at Craft Stores, OR eliminate all guess work and get on-line to www.houstonart.com Good-Luck
