Golden Polymer Varnish with UVLS (Ultra Violet Light Stabilizers) is a water-based acrylic polymer varnish formulated to provide additional protection from ultraviolet radiation. This helps delay the inevitable fading that occurs in materials that may be fugitive in nature.
Polymer Varnish is designed as a topcoat for acrylic paints and offers a removable protective surface to the relatively soft acrylic paint layer. It has a harder film than most acrylic paints, which diminishes the susceptibility of the surface to dust and dirt, and provides increased protection from scratching, marring and moisture. It has adequate flexibility to withstand normal handling conditions, including loose rolling. Do not use for oil paintings. For interior use only. The product is not recommended for use on furniture or other surfaces subject to physical contact during use.
Polymer Varnish remains soluble in alkaline solvents, such as ammonia. This means the varnish can be easily removed; taking with it any accumulated surface contamination without damaging the painting surface. The use of such a removable varnish provides a valuable tool to anyone trying to restore or clean a painting.
Polymer Varnish (Gloss) dries to a highly reflective finish. Polymer Varnish (Satin) offers moderate reflection, similar to most matte varnishes. The Matte is exceptionally flat. The different finishes can be intermixed, or used sequentially, to achieve the desired sheen. Note: Polymer Varnish (Satin) and (Matte) will lighten dark value colors, which is typical of non-gloss varnishes.
Prior to actual use, it is very important to experiment with Golden varnishes on test pieces to become aware of how they perform and how they alter the surface appearance of paintings. 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.
Polymer Varnishes must be thinned with water before use. Start with 4 parts varnish to 1 part water for brush, 2 to 1 for spray. Adjust as needed. The 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. Thinning the varnishes beforehand will also minimise the risk of foam by allowing any bubbles to release before drying.
It is preferable to brush or spray apply Golden varnishes. Other methods, such as sponging or rolling, are not recommended, as they may result in problems such as: foaming, loss of film clarity, non-uniform coverage, excessive film build, sagging, or deposition of materials from the application tool.
