The UVLS system provides increased resistance to the harmful effects of ultraviolet radiation, making the product suitable for exterior as well as interior applications. For restoration purposes, the varnish may be removed with MSA Solvent, full-strength commercial mineral spirits ( i. e.: paint thinner or white spirits ), or distilled or rectified turpentine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMSA Varnish can be used over a wide variety of paints, including acrylic, oil, alkyd, watercolor, and casein. \u003c\/strong\u003eAs a topcoat for acrylics, it provides a harder, lower tack surface that is much less susceptible to dirt and is more mar resistant.\u003c\/p\u003e\n\u003cp\u003eMSA Varnish (Gloss) dries to a highly reflective finish. MSA Varnish (Satin) offers moderate reflection, similar to most matte varnishes. MSA Varnish (Matte) finish is exceptionally flat. The different finishes can be intermixed to achieve the desired sheen. Note that the matte and satin MSA varnishes will lighten dark value colors, which is typical of reduced sheen varnishes.\u003c\/p\u003e\n\u003cp\u003eAs a solution polymer, MSA Varnish is clear when wet. Compared to aqueous varnishes, this allows for better visual properties during application. It also suffers significantly less from foam generation and pinholes that can detract from the clarity and appearance of the finish. The varnish produces an extremely level finish and is able to coat slick supports including glass and most plastics and metals.\u003c\/p\u003e\n\u003ch5\u003e\u003cstrong\u003eMSA Varnishes must be thinned before use\u003c\/strong\u003e\u003c\/h5\u003e\n\u003cp\u003eThe varnishes are supplied thicker than meant for application in order to keep the matting solids in the Satin and Matte finishes from settling to the bottom, which can result in a streaky, uneven appearance when applied.

For best results, apply to a test piece that is similar in composition as the artwork to be varnished. This will help ensure that all variables are accounted for, and a successful varnish application will be achieved.\u003c\/p\u003e\n\u003ch4 id=\"iso\"\u003e\u003cstrong\u003eISOLATION COAT\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003eApplying an isolation coat before varnishing is only recommended for acrylic paintings. \u003cstrong\u003eDo not use an isolation coat on oil paintings.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eOn acrylic paintings, an isolation coat is helpful if future conservation or varnish removal is ever needed. It is a permanent, non-removable coating that serves to physically separate the paint surface from the removable varnish. This will help protect the surface if the varnish is ever removed and make future cleaning and conservation easier to avoid working directly on top of the pigmented part of the work. Therefore, even if painted with delicate washes or large areas of colors that could potentially bleed, a clear barrier would safely cover the painted surface. It will also seal absorbent areas, which will result in a more even application of the varnish. In the event that no varnish gets applied, the isolation coat serves to decrease the water sensitivity of the paint surface, affording protection during routine cleaning\/dusting.\u003c\/p\u003e\n\u003cp\u003eGiven the current state of conservation science, we feel the use of an isolation coat provides the most protection. However, isolation coats are also significant and permanent additions to a painting and inevitably will cause changes in the painting\"s surface qualities. Whether these changes are acceptable is an aesthetic decision that each artist needs to make after sufficient testing. In addition, since it is non-removable, any mistakes or problems during this procedure cannot be easily corrected and there is always an element of risk that needs to be considered. We strongly encourage the artist to practice these procedures thoroughly so they feel confident and become familiar with any unforeseen problems. \u003cstrong\u003eIf you have any questions or concerns regarding the proper use or application of an isolation coat, please call or email Golden's Materials and Applications Department: help@goldenpaints.com \/  (800) 959-6543.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eFor brush application, the appropriate isolating medium can be made by diluting Golden Soft Gel Gloss with water (2 parts by volume Soft Gel Gloss to 1 part water). If a spray application is desired, a 2:1 mixture of Golden GAC-500 to High Flow Medium can be applied with an airbrush, touch-up spray unit or commercial spray equipment. The absorbency of the surface will dictate the number of isolation layers required. For relatively non-absorbent surfaces, as is the case with a uniform paint layer, one coat brush applied or two coats spray-applied are recommended. For more absorbent surfaces, which tend to be very matte, it is recommended to apply sufficient isolation coats to achieve a satin sheen on the surface. This may require two or more brush applied coats or three or more spray applications.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe isolating layer is of critical importance when applying a matte varnish over an absorbent surface to prevent a cloudy or \"frosted\" appearance from occurring. \u003c\/strong\u003eThis frosted appearance results from the varnish and solvent being absorbed into the support, while the matting agent remains exposed on the surface. While we have carefully selected the matting agent that is in Golden varnishes to be as transparent as possible, it is still a dry particulate material. When the matting agent is deposited onto the surface and is not a part of a continuous varnish layer, it appears as a white solid. If varnishing water-soluble paints, including watercolor, gouache, and tempera, the isolation coat must be sprayed on in very light layers to avoid solubilizing the paints, which could cause loss of distinctness of the underlying image.\u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003ePRODUCT APPLICATION\u003c\/strong\u003e\u003c\/h4\u003e\n\u003ch5 id=\"GeneralGuidelines\"\u003e\u003cstrong\u003eGeneral Guidelines\u003c\/strong\u003e\u003c\/h5\u003e\n\u003cp\u003eDO NOT apply Matte or Satin varnishes to an absorbent, unsealed surface as frosting or streakiness can occur.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eACRYLICS: The use of an isolation coat is recommended.

The Da Vinci Cosmotop Spin brushes are an example of this type. The size of the piece to be varnished will determine the size of the varnish brush. Work from a shallow container to help control brush loading. The varnish solution should wet only the lower 25-30% of the length of the bristles. \u003cstrong\u003eIt is always best to apply the varnish on a horizontal surface in order to minimize running or sagging. \u003c\/strong\u003eIf vertical application cannot be avoided, as with a mural, it is extremely important that the varnish be thinly applied. In either case, it is better to apply two or three thin coats with sufficient drying time in between, rather than one thick coat of varnish. The latter will take longer to cure, staying soft for some time, and could result in drips or a cloudy film. Apply the varnish in a manner that allows it to be brushed out to the most uniform, thinnest film possible. Mentally divide the work into regions to be covered by each loading of the brush. These may be based on a systematic grid-like sequence or may follow natural boundaries of the piece. Maintain an even application by working from the center of each region outward. Lightly overlap into still wet, adjacent sections. When applying a satin or matte varnish, never apply more than two coats. A thick film of these reduced sheen varnishes will result in film cloudiness, and loss of clarity.\u003c\/p\u003e\n\u003ch5\u003e\u003cstrong\u003eSpray Application\u003c\/strong\u003e\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eThe best way to achieve an even coating of varnish is to spray apply. \u003c\/strong\u003eThis is particularly true for impasto surfaces. Spray application is required for any surface where the paint film is fragile, such as gouache, and should not be touched by application tools. Spraying is also a useful technique for creating a matte surface. The size of the surface to be sprayed will determine the best type of spray equipment to use. These varnishes can be sprayed from an airbrush, airless or air pressured spray equipment, or refillable aerosol equipment. In preparation for spraying, make sure all equipment is free of dirt. Work in an area free of dust and dirt and keep work off the ground when spraying. \u003cstrong\u003eSpray three to four light even coats instead of one or two thicker applications\u003c\/strong\u003e, allowing enough time for drying between coats (1-4 hours, until surface is tack free). Release the spray trigger if the motion of the airbrush is stopped during application in order to avoid an uneven build of varnish in one spot. \u003cstrong\u003eMaintain uniform distance from the surface\u003c\/strong\u003e, and avoid the tendency to use an arcing motion. Make straight passes across the work, changing direction once the spray has cleared the edge of the piece being varnished. Slightly overlap the spray pattern with each pass, until the entire piece has been covered. To aid in achieving a more even application, turn the painting 90 degrees in order to apply the subsequent coat perpendicular to the previous one. A typical spray application lays down a film only 1\/6 to 1\/4 the thickness of a brush coat application. \u003cstrong\u003eIf maximum protection is required of the varnish layer, apply multiple coats. \u003c\/strong\u003eThis is especially important when protecting colorants that are not inherently lightfast, as the thicker the total varnish film, the greater the protection from ultraviolet radiation. \u003c\/p\u003e\n\u003ch5 id=\"MuralsAndArchitecturalApplications\"\u003e\u003cstrong\u003eMurals and Architectural Applications\u003c\/strong\u003e\u003c\/h5\u003e\n\u003ch6\u003e\u003cstrong\u003ePLEASE NOTE the Following Restrictions\u003c\/strong\u003e\u003c\/h6\u003e\n\u003cul\u003e\n\u003cli\u003eGallon sizes of our standard MSA Varnishes and Acrylic Glazing Liquid cannot be used for architectural applications, including interior and exterior murals painted directly onto walls and ceilings.\u003c\/li\u003e\n\u003cli\u003eQuart containers of our standard MSA Varnish and Acrylic Glazing Liquid are allowed and can be used.
