What are Paint Binders?

Oil paint, acrylic paint, and watercolour all have one thing in common: they are all types of paint. But what sets them apart is the type of binder used. The binder is responsible for holding all the other ingredients together and giving paints their desired consistency. Oil paint uses oil as its binder, while acrylic paint uses a synthetic polymer. This difference in binders results in different properties for each type of paint. For example, oil paints take longer to dry than acrylics, and watercolours are more transparent. Knowing the characteristics of each type of paint can help you choose the right one for your project. Also, take a look at this Flux Pumps resource if you’re looking for that information.

What are Pigments?

Pigments have been used by humans for thousands of years, and the earliest examples were made from coloured earth. These pigments, known as earth colours, typically have a muted hue and are derived from minerals such as iron oxide. Yellow ochre is one of the most well-known earth colours, and it was used extensively by prehistoric cultures for paintings and cave art. While earth colours are still used today, modern pigments are often made from synthetic compounds that can produce a wider range of colours.

Should Beginners Use Artificial Pigments?

Many beginners who are just starting to get into painting make the mistake of thinking that using artificial pigments will help their painting to last longer. However, nothing could be further from the truth. In fact, artificial pigments can actually cause a painting to degrade much more quickly than if only natural pigments were used. The reason for this is that artificial pigments are not as stable as natural pigments, and over time they can break down and bleed into the paint, causing it to become discoloured and muddy.

Additionally, artificial pigments often contain chemicals that can be harmful to the paint, causing it to crack and flake over time. For these reasons, it’s always best to stick with natural pigments when starting out in paintings. Not only will your painting look better in the long run, but you’ll also avoid any potential damage that could be caused by using artificial pigments.

What are Oil Paints and How Long Do They Dry?

Oil paints are made from a combination of pigments and binders. Pigments are the coloured particles that give paints their colour, while binders are the substances that hold the pigments together. Oil paints have been used for centuries, and their popularity lies in their ability to produce rich, velvety colours. They are also slow-drying, which gives artists ample time to work on their paintings. However, this property can also be seen as a downside, as oil paintings can take months or even years to fully dry. Despite these drawbacks, oil paints remain a popular choice for artists who want to create high-quality artwork.

What are Acrylic Paints and How Long Do They Dry?

Acrylic paints are a type of water-based paint made with pigments suspended in acrylic polymer emulsion. Since their introduction to the market, they have become a popular choice for artists of all levels due to their versatility and ease of use. Acrylics can be used on a variety of surfaces, including canvas, wood, metal, and glass. They can also be blended together to create an infinite number of colours, making them ideal for both amateur and professional artists alike.

When it comes to drying time, acrylics fall somewhere between oil and water-based paints. Unlike oils, which can take weeks or even months to dry completely, most acrylics will set in just a few hours. However, they will remain slightly flexible even after they’ve dried, which means they won’t crack or chip as easily as other types of paint. And while they’re not quite as fast-drying as watercolours, they’re still much quicker than oils. So if you’re looking for a versatile paint that dries quickly and won’t damage your surfaces, acrylics are a great option.

What is Watercolour and How Long Does It Dry?

Watercolour is a type of paint made from pigment suspended in water. Unlike other types of paint, watercolour can be reworked while it is still wet, allowing for a greater degree of control and flexibility. When applied to paper, watercolour spreads out evenly, resulting in a smooth, even finish. Depending on the amount of water used and the absorbency of the paper, watercolour can take anywhere from a few minutes to several hours to dry completely. While it is possible to speed up the drying process with a hairdryer or fan, this can also cause the paint to become streaky or blotchy. For best results, watercolour should be allowed to dry naturally.
