Kölner Aqua Size Thick

Kölner Aqua Size Thick (Anlegemilch) is the viscous size variant of Kölner Aqua Size, specially formulated for imitation gold leaf. The open time is up to 60 hours and enables large areas to be covered at once. The surface must be dust-free and, if possible, non-absorbent. The wait time after applying the size and gilding is about 30 minutes. The quick adhesive is water-based and water-dilutable. When applying with a foam roller, adding a few drops of defoamer is recommended. The Kölner Permacoll HA product is similar in application to the Aqua size, only further developed and enables a higher quality result.

Kölner Aqua Size Thick can only be applied as thinly as oil mixtion, so it is only partially suitable for gold leaf. It is ideal for imitation gold leaf and other metal leaf.

How to Apply Kölner Aqua Size Thick

1. The surface must be dust-free and, if possible, non-absorbent.

2. Apply the size with a soft and fine hair brush.

3. Wait for about 15 minutes till the size becomes tacky, not wet or dry.

4. You now have up to 60 hours to gild before the size becomes dry. The drying time is affected by temperature, humidity, and the gilding surface.

5. When gilding with imitation metal leaf, it is best to use Gilder’s Gloves to avoid leaving fingerprints on the metal leaf, as fingerprints will appear after you finish gilding.

6. To apply metal leaves onto the surface without scratching the metal leaves, use Gilder’s Gloves.

For gilding glass, metal, and plastic, Kölner Permacoll HA has the same application as the Kölner Aqua Size, but it is further developed to enable a higher polish on these types of surfaces.
