Today, Winsor and Newton remain the premier choice for artists, offering a wide variety of fine art supplies including: oil, water colour, acrylic and alkyd paints, pastels, artists' brushes, canvases, papers and portfolios. Our varnishes offer physical protection from knocks and dirt, plus an extra layer of UV-light protection. It’s only a bad idea as a final covering as they aren’t tough enough to provide long-term protection. If so it might simply be unrealistic for a painting (again, texture in the work will be hard to conceal without a pretty thick coat) but if you paint on a rigid support and permanence isn’t an issue you might consider using what they use on bartops, I’ve seen it used over decoupage so I’m sure it would work over acrylic paint and the finish is incredible.

The more you disturb it by brushing over the same area the more likely you are to form bubbles or lift partially-dried varnish. Seal your acrylic work with a transparent, gloss acrylic layer which is breathable, permanent and protects against UV damage. The only difficulty I experienced doing it the second way was occasional really tiny bubble forming.Each brushstroke should slightly overlap the previous so that you don’t leave thin spots or narrow bands uncovered but if these do occur don’t overwork the surface trying to rectify it, leave it for the next coat to even out. Please keep all directions of strokes the same to help keep the varnish looking flat, and when varnishing and drying be sure that your workspace is at room temperature, or you may run the risk of your varnish drying slightly cloudy. Please note- Varnish should not be transferred into plastic containers, as it may damage the plastic. From Winsor and Newton, an excellent range of aerosol varnishes (seven in all) covering most of the key media areas where artists are involved.

Most people don’t realise that your typical water-based acrylic varnish is not really removable from an acrylic painting, Liquitex at least acknowledge this fact by stating their acrylic varnishes are permanent. Suitable for application over acrylic paints both interior and exterior, the coating will also protect against UV damage.
