Winsor & Newton Professional Acrylic Medium, Glazing Medium, 125ml (4.2-oz)

Love Winsor Newton! Really great product!

This is great stuff forslow drying your paint so your can work it more. It is fairly pricey though.

As described

Expensive if not for a sale deal. I like that it's clear a gesso. It's goes on white and dries clear. Seems to work well on canvas

I am not professional but have considerable experience with W&N matte varnish at least when airbrushing. In August 2021 I completed preparation of a middle earth poster (also purchased from Amazon) that came with a very glossy finish. After mounting but before framing I airbrushed the poster's surface with W&N matte varnish. The varnish removed the gloss making the map look more realistic. I took a photo with my cell phone (without flash) to show the effect. The left side of the map is how the entire poster actually looks to the eye. The right side of the map is a natural light bloom in the room . The important thing to note is how this skimming light is effectively scattered as it should be with a matte finish.I use this W&N varnish whenever I want a truly matte finish as was also done on this large model airplane. The photo was taken in bright sun and the matte varnish provided the desired dull military like finish while also eliminating any bright reflections.Again I only have airbrush experience with this varnish. When using it in this way a flow improver (also W&N) is - I believe - necessary. The varnish's viscosity and fast drying capability will clog up the airbrush without the flow improver. Also the varnish needs to be properly atomized for application and the flow improver does the job here as well. I add the improver to the airbrush cup in a mix with the varnish. The amount is best learned through experience. I set the airbrush pressure at about 30-35 psi. When airbrushing a little varnish goes a long long way.One additional note is that I have found the varnish to dry "clear" - that is not yellowing or changing the color of the underlying acrylic. (My experience seems to conflict with some other observations.)

Easy to use, blends acrylics.

Before buying, I was wondering what type of sheen this product has (gloss, satin, matte, etc.), and is it truly clear? I would say it’s a matte finish because of the fine grit suspended in the gel. There is a haze of milky white when you first apply, which fades to nearly clear. It produces a very workable surface for opaque media. It’s very smooth to apply and dries quickly. Overall, it’s very helpful.

Great product for painting. Does exactly what it is suppose to do. Extends the drying time and makes a really lovely painting when you blend with it. Smooth on the brush, My only complaint is that the bottle is tough to squeeze. I would still purchase this product repeatedly.

Passed onto an artist who works with wood, she loves it.

So glad I got this. Works wonders

Everything was ok and on time.

Isolation coats
