Did you know that Winsor & Newton is a famous brand for manufacturing oil painting supplies? On the other hand, Liquitex is famous for Acrylic painting supplies. All the mediums including paints, gesso, selaers, etc. are manufactured by Liquitex.

Liquitex Professional Gloss varnish comes in 237 ml plastic bottle packaging with a gloss finish. It is also intermixable with Liquitex acrylic paints. The item is slightly lightweight, nontoxic, and water resistant. Once the varnish dries, it becomes permanent and non-removable.

The best way to apply the varnish is by using a soft sponge. In case you use a brush, the painting could get brush marks that will be non-removable after drying of varnish. To use the selaer, just take a soft sponge and apply a thin layer of gloss varnish. Make sure you don’t touch the painting surface once the varnishing is completed.

This varnish is officially made by Winsor & Newton and comes in a 225 ml plastic jar with a labeling of Winsor & Newton. However, the price of UV satin varnish is 25% more than other varnishes but the quality of protection is really extended in this item. It is designed for professionals only.

Instead, there are variants that suit multiple situations such as UV-resistant varnish will protect the painting from sunlight, dust, and dirt. But this is a choice of artist whether he likes glossy, satin, or matte varnish.


Can Mod Podge be used to seal acrylic paint?

Mod Podge is a glue-like sealer that is non-toxic in nature. It comes in a jar made in the USA that can be used to seal acrylic paintings as well as other art projects. However, it is nontoxic in nature which also makes it a favorable choice for artists to seal acrylic paintings.

What is the difference between Mod Podge and acrylic varnish?

Mod Podge was basically created for adhesion and sealing that dried between 15 to 30 minutes and was used for craft projects. On the other hand, acrylic varnish was only designed for sealing acrylic paintings. It dried for a few hours and cannot be used for adhesion.
