Permacoll Gilding Size is a permanent, acrylic-based adhesive for indoor use. It provides stronger adhesion than Instacoll Size, making it well-suited for gilding with imitation gold, copper, and silver. This adhesive delivers a bright, reflective finish on all types of metal leaf, including imitation gold, silver, copper, and variegated. The red Permacoll variant can replicate the look of traditional poliment gilding.
Kölner Permacoll HA (High Active) is formulated specifically for imitation metal leaf. While standard Permacoll Size suits thin, genuine gold and silver. Imitation metal leaf is thicker and heavier than genuine gold leaf, so it needs a stronger adhesive. Permacoll HA offers enhanced grip, ensuring secure application and a bright finish.
Extended open time: Permacoll dries to a permanent, tacky surface within 15 to 30 minutes, giving you several hours, or even days, to apply metal leaf. This flexibility removes the strict timing required by traditional oil sizes and helps achieve the depth and appearance of traditional clay bole gilding.
