Montana UV-EFFECT is a transparent effect paint that is only visible under direct UV light. Able to be sprayed on nearly any substrate, the colorless and semi-gloss paint is not visible in sunlight rather illuminates when exposed to UV light with a glowing, blue-purple colour. Ideal for indoor use, the luminous spray can be a great tool not just for making art or art happenings, but also in practical contexts such as Guerilla Marketing, night clubs, venue and property marking. The Montana UV effect Spray can be applied to numerous substrates such as coated and uncoated screens, masonry, wood, glass and more. The UV light effect becomes more prevalent, the more coats are applied particularly when applied with a stencil. *Visibility: Due to the UV EFFECT’s semi-gloss finish, the UV EFFECT spray can be slightly visible if painted on a matt substrate. The application of the Montana GLOSS Varnish can be used to create an all over gloss finish which discretely hides the UV spray under one gloss coat. The UV EFFECT spray is compatible with other colour and effect coatings within the MONTANA CANS range as long as total curing time has occurred. (24-48 hours). Applying in thin, multiple layers will enhance and increase the UV EFFECT sprays ability to produce a vibrant glow effect. To add durability and protection, the fully dry and cured surface can be sealed with Montana VARNISH Spray in Matt, Semi-Gloss or Gloss. Always test spray on a non-visible area to check compatibility of lacquer or paint. 400ml. UK shipping by road only. Not available for International or Northern Ireland delivery.
