Whitson’s Universal Lacquer
Whitson’s Universal Lacquer is a specifically formulated semi-gloss lacquer. Developed using Cait Whitson’s expertise it is superb for protecting metal leaf. It works over many leaves, including precious metals like gold and silver, and also imitation gold and silver leaves. The lacquer has excellent film properties and dries to a hard, but flexible film. This film protects gilding and metal finishes from moisture and atmospheric gases, reducing the risk of tarnishing or oxidisation. It is suitable for application by brush, spray and roller and is touch dry in under an hour!
When using this lacquer the surface must be thoroughly cleaned and degreased. Failure to clean the surface can lead to cissing and the lacquer not adhering. This step is essential when applying the lacquer over metal leaf.
For cleaning we recommend using a clean and non-abrasive cloth dampened with a neutral cleaning agent.
Always ensure the Lacquer is well-stirred before application. Stir, rather than shake lacquer, to avoid introducing air and bubbles into the lacquer. Ensure all your tools and containers are as clean as possible. Any contamination while applying the lacquer can cause discolouration or a substandard finish!
When applying the Universal Lacquer on leaf we recommend laying the first layer very thinly (60 – 80 micrometre wet film thickness.) Over-application may result in discolouration of the finish.
For best protection it is highly recommended to apply two coats of the Lacquer, following the overcoat times in the TDS.
