Before applying them, take a small quantity of the chosen colour and mix it in a clean container using your gloved finger until the desired hue is achieved.

Add oil varnish in a 1:1 ratio and mix until a homogeneous colour is obtained, with Classical Amber Varnish being the optimal choice. Testing the colour on a transparent plastic or wood sample is recommended to ensure the expected hue is reached. 

Apply the mixed product by hand using vinyl or nitrile gloves, spreading thin and homogeneous layers as a glaze. For hard-to-reach areas, use a brush.

After applying, remove any excess product by wiping the gloves with a clean, lint-free cloth. If using a brush, follow the same steps, but note that more varnish and a small amount of solvent may be required.

Allow each layer to dry under UV light for at least 8-10 hours when applied by hand, with additional drying time needed for brush applications. Apply alternating thin layers of clear varnish without colours, sanding each dried layer with a linen cloth or micromesh paper to remove dust and improve adhesion.

Repeat this process 3 to 4 times to achieve the desired colour, finishing with 2 or 3 layers of clear varnish to seal the colour.
