Painting on glass: Vitrea 160 and Vitrail : the Q&A Vitrail

Vitrail: How do you lighten Vitrail colours?
Use the Vitrail Lightening Medium to create lighter colours without reducing the quality of the colour, or making it more fluid.

Vitrail: How should I dry the finished object?
The object must be kept in a dry, dust free environment for the 6-8 hours required for drying.

Vitrail: What other products can be used with Vitrail colours?
Play the opposition between transparent and opaque colours by using Vitrail colours with the Ceramic colours and Cerne Relief Outliners. Also create amazing effects with the NEW Fantasy paint ranges of Prisme and Moon.

Vitrail: What is the bath technique?
This simple and funny technique allows for marbled effects. Pour a few drops of different Vitrail colours into a container of water. The drops fuse upon contact with water and give amazing effects. Then transfer the colour by dipping your object into the water to transfer the colors onto the piece.

Vitrail: Should I bake the decorated object once dry?
Absolutely not! Vitrail colours are not baked! Once dry, they become hard and enamel like and are resistant to hand washing in cold water without soaking, and to window cleaners.

Vitrail: Can the decorated objects be placed in contact with food?
No, only surfaces not intended for food contact may be decorated.

Vitrail: How do you thin the paint if it seems too thick?
Add a small quantity of Vitrail thinner or odourless mineral spirits and stir thoroughly.

Vitrail: Is the application of Vitrail colours carried out vertically or horizontally?
In order to apply our Vitrail product, we recommend using a horizontal surface. The product is actually very runny and horizontal application allows you to apply a thicker layer thus allowing for a greater depth of colour and no risk of dripping.
Vertical application is also possible. The best thing to do is to cut the plexiglas to the size of your windows to work with the Vitrail (stained-glass) colours horizontally on your table. After drying, place the plexiglas against your window on the inside, and then stick it onto the frame of your window. Putting the decoration between the glass and plexiglas is the best thing to do as the effect is superb. If you worked with cerne relief, it will flatten a little and give a nice effect (imitation lead strip).

What is the durability of applying Vitrail to a bathroom mirror?
We do not recommend the use of our Vitrail paint in damp rooms such as bathrooms.
We cannot guarantee you great durability in this case, the film may gradually lose its shine.

Vitrail: What should I do with a varnish applied on crimped stained-glass?
You should strip it all and start again.
Wait until the Vitrail is dry before painting with lightener (2.4.1.1.4.3)

Vitrail: Can you apply it to incandescent light bulbs?
Yes

Vitrail: Can you use the VITREA 160 instead of CERNE RELIEF?
No, the Vitrea 160 cerne must be baked.

Vitrail: How much matte medium should I add to get a nice matte effect?
The optimum effect is achieved with a 50/50 blend but the shade will be less concentrated.

Vitrail : What's the size of the lead strip?
2 times 3 mm in width, 10 m in length.

Vitrail : Can the lead strip be used with Vitrea 160?
Yes: The lead and adhesive are resistant to baking for 40 minutes at 160 °C and at least 2 washing cycles in the dishwasher.

Vitrail: How do you prepare the surface to be painted?
Carefully degrease the surface to be painted with soapy water or alcohol.

Vitrail: After applying the Cerne Relief outliners, how long do you wait before applying Vitrail colours?
It is better to allow the Cerne Relief dry at least 30 minutes prior to applying the Vitrail colours.

Vitrail: How do you prevent the colours from running?
In the case of a rounded object, work on the most horizontal part. Let dry a few minutes, turn the object and repeat. For vertical surfaces, add Vitrail No-Drip Medium to the paint to increase adherence and prevent the colours from dripping down the surface.

Vitrail: How do you correct a mistake?
If the colour is wet, use a cotton swab dipped in odourless mineral spirits to remove the Vitrail colours. If dry, scrape the colour off with a razor blade. Cerne Relief Outliners may be removed with water.

Vitrail: How can you get a straight line with the Cerne Relief Outliners?
Before starting, always wipe the excess paint from the nozzle of the tube. When applying, use the tube like a pencil and gently squeeze the tube to apply even pressure.
