Winsor & Newton Professional Acrylic Medium, Slow Drying, 250ml (8.5-oz)

This slow drying medium is definitely effective and doesn’t require much to do the job. The small bottle lasts a long time and keeps paint from drying too fast. If initially liquidy the paint will change consistency as it’s exposed to air. It’ll become thicker, but still perfectly useable. 10/10

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.

This stuff is comparable to "Golden" mediums, it works incredibly well. 10/10

Love Winsor Newton! Really great product!

It gives you some more working time for acrylic. I found it itself needs a bit of water to be useful. The one detraction I have it that using the medium on an already dried surface will loosen the color, even though theoretically acrylic has dried into a plastic. I've open up some "holes" in pieces where multiple layering and blending is why I wanted the product. Perhaps mixing it with some glazing medium would help- but might as well just use glazing medium.

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

Easy to use, blends acrylics.

I got this for my painting by numbers, ceramics, models, canvases, etc. This is a game changer too me! I was worried it would mess up color etc. I also use it in my brush before loading paint to keep paint from drying on brush.

I bought this extender to use with my acrylics to enable better blending. So far I have used it once and I am very pleased with the results.

I use this to slow the drying of my acrylic paints when shading skin tones on my paint by numbers. The gel like consistency goes a long way, with only a small drop needed. I'm still mastering my technique of shading, but do find this product helps.

Excellent quality, very recommended.
