About Amsterdam mediums

Use your paint to its full potential with Amsterdam mediums. Painting mediums are incredibly useful because they allow you to adjust the properties of the paint to your preferences. Whether you want to make your paint thicker, glossier, thinner or more matt, everything is possible with Amsterdam’s extensive assortment of mediums, ranging from slow drying and glazing to thickening and pouring mediums in different variations and sizes.

What is the difference between Amsterdam slow drying medium and acrylic retarder?

The biggest difference being that the slow drying medium is a pre-mixed, ready-to-use medium that also contains acrylic resin, which makes it much easier and safe to use in any quantity. Like with any medium, adding a large amount will make the paint thinner and more transparent.

The acrylic retarder, on the other hand, has little effect on the viscosity and opacity of the paint. You should be careful adding the acrylic retarder to your paint, though, and only add a maximum of 5%. If you add too much, your paint will turn rubber-like and become unusable.

Both products delay the drying time of acrylic paint with a maximum of 20%.

What medium can I use for acrylic pouring?

For acrylic pouring, we recommend adding Amsterdam pouring medium to your acrylic paint or ink. This medium is specifically developed to be self-leveling and increases the flexibility of the paint film to prevent cracking. Depending on the desired flow, you can adjust the mixing ratio to your liking. You can also add water to make the mixture even more fluid.

Can I use glazing techniques with acrylic paint?

Amsterdam glazing medium allows you to add even, transparent layers to your work. This medium makes your paint smoother, easier to spread and more even (without visible brush strokes).

The medium is self-leveling, so it helps you create those beautiful glazing layers to achieve an optical color mixing effect with the colors of the underlying layers. Glazing works especially well with transparent colors in the final layers of your painting. Adding a medium also makes the paint film even more elastic and flexible.

How can I add printed images to my work?

Amsterdam photo transfer gel has been specially developed to allow you to include laser-printed images in your work. The gel only works with laser-printed images, photographs and inkjet-printed images are not suitable.

How can I add more volume to acrylic paint?

If you’re looking for some extra volume and dimension, try mixing your acrylic colors with one of the Amsterdam gel mediums: gelheavy gel and extra heavy gel. These mediums offer a sharper, pastier texture and give your work, depending on the selected gel, a glossier or more matt finish.

Due to their adhesive properties, these gels also work well for different mixed media techniques. Keep in mind that these mediums contain water, so they will lose volume during the drying process when the water evaporates.

How do I thin acrylic paint?

Thin your paint using Amsterdam acrylic medium. Amsterdam acrylic medium adds acrylic resin to your paint to optimally protect the pigments and to help you easily spread your paint, while retaining the durability of the paint film. Your paint will last longer since it’s easier to distribute, so you can cover more of your surface with the same amount of paint. Adding more of this medium will result in higher transparency of the color.

Can I thin acrylic paint also with water?

Acrylic colors can easily be thinned using water. If, however, you use large amounts of water, only a small amount of acrylic resin will be left on your work. The pigments will not be properly protected and might smudge once the water has evaporated. It also makes the paint film thinner and more fragile, which increases the risk of damage during transportation or when being wrapped up. Very thin paint may also have trouble adhering to certain surfaces. To prevent this from happening, thin your paint using Amsterdam acrylic medium.
