Water-based varnish

Use method

Applied to reactivate the adhesive power of the base (component 1, sold separately, Kolner base size mettiamo link!) if it dries during excessively long size to gold leaf application time frames. Apply the activator across the surface with a brush or pad in as thin a layer as possible. Before applying the leaf check that the activator is dry or the gilding may be opaque or patchy. It only takes a few minutes to dry. The activator can be used a long time after size application, too. Once the first portion is gilded, move on to the next section, applying activator to the edges, too (approx. 1mm) of the area already gilded to allow homogeneous leaf adhesion. For a uniformly gilded result, rub the gilt surface with a cotton cloth.

Additional information

Dilution percentage, application method and quantities applied may significantly affect workability time frames. The most suitable application methods should be determined experimentally on the basis of support used and desired result.
