What is Montana VARNISH?

Montana VARNISH is an acrylic based clear coating that can be used to seal and protect surfaces from oxidation and damage from UV light exposure. It is quick drying and ideal for art, hobby, crafts and DIY projects.

What surfaces can I use Montana VARNISH on?

Montana VARNISH can be used on many surfaces including paint (with the exception of synthetic based paint), canvases, paper, charcoal, drawings, various fibres, wood and photos.

Does it come in different finishes? And when do I use which one?

Yes. Montana VARNISH comes in three different finishes. Gloss Varnish, Semi Gloss Varnish and Matte Varnish. Each varnish enables users to achieve a finish as desired. Gloss levels are as depicted on the donuts on top of the cans. As the function of all three is the same, deciding which one to use when is a subjective to the finish that is desired for the project.

Is the Montana Varnish archival?

Yes. Montana VARNISH is acid free and non-yellowing. It does not desaturate your artworks and can be used for interior and exterior use. All varnishes contain UV blockers to protect your projects. The more coats applied, the greater the UV protection.

How do I start using my Montana VARNISH can?

Remove the spray nozzle and turn the can upside down. Strike with your palm allowing safety ring to fall out. Shake vigerously for 2-3 minutes ensuring you can hear the mixing balls moving freely. Replace the cap back onto the top of the can valve and trigger away from substrate to test. If flowing freely you can start painting.

Is Montana VARNISH acrylic?

Montana VARNISHES are solvent based, nitro-acrylic paint. The solvents evaporate rapidly once applied leaving a clear protective, acrylic coating behind once dry.

Is Montana VARNISH Low Pressure?

Montana VARNISH is low pressure, meaning the gasses in the can allow the varnish to be ejected slowly and smoothly. This can reduce spray dust, improve precision and increase how accurately users can apply varnish.

How far should I hold the can away from the substrate while painting?

Optimum distance from substrate is normally beween 15 and 25cm depending on your task. The closer you hold the can, the more paint is applied to a smaller area. The further away you hold it, the thinner the paint film applied will be.

How long does Montana VARNISH take to dry?

Drying time is usually 10 minutes to be touch dry. This can vary depending on substrate, ambient temperature, humidity levels and thickness of coats applied. The three stages of drying are apx: touch dry in 10 mins, working dry in 60 mins and chemically cured in 24 hours.

My Montana VARNISH has wrinkled. Why is this?

To gaurantee no wrinkling, you need to apply the varnish in thin coats and ideally allow the varnish time to cure before applying further coats. As all coatings shrink to some degree when drying, wrinckling occurrs when one layer of varnish is drying and pulling the level below it that has not yet cured. A cured layer can with stand this movement.

Can I paint over Montana Varnish with other paints?

You can paint over Montana Varnish with oil based paints once the varnish has cured. Painting over with acrylic paints can work, but may result in cracking at a later stage subject to the quality of the acrylic paint. MONTANA VARNISH is NOT compatible with synthetic based lacquers!

How do I get the smooth coverage?

It is very important to shake well and apply all coats thinly. Changing your application direction (horizontal and verticle) after each coats is also benefitial.

What kind of packaging materials can I use to transport / store my painted objects?

When transporting or storing painted objects, it's crucial to steer clear of air bubble wrap or similar packaging materials. These films may contain plasticizers that can gradually evaporate, resulting in unsightly marks or discoloration on the painted surface. Additionally, they can harbor silicone residues, oils, or fats from production, leading to imprints on the paint.

To safeguard your painted surfaces, it's advisable to utilize alternative packaging materials such as foam sheets, soft blankets, cardboard, or other suitable options. These alternatives provide effective protection without the risk of damaging the paintwork.
