This is most likely the most crucial rule in oil painting, especially if you're painting wet on wet (a technique where you do not let the paint dry in between layers). If you don't, all your hard work will be ruined when you go to apply another layer. So yes, you should wet your brush before use.
The reason why you need to wet your brush is that oil paints are viscous materials that are thick when they first come out of the tube and will thin out as they warm up to room temperature. Therefore, it's important to keep them moist so they'll blend better with other colors and not look like they were applied with a knife.
Wetting your brush also prevents your hair from drying out too quickly which could lead to problems such as breakage or dullness. Finally, water makes the bristles softer which helps oils flow more easily.
You should wet your brush by dipping it into a bowl of water and then shaking off any excess water before using it to avoid contaminating your paint. However, some people say this can damage your brush by shrinking its hairs too much which would make it difficult to get an even coat of paint on your canvas.
Some artists say you shouldn't wet your brush at all while others do so occasionally.
Always begin your painting with a tiny layer of medium in your oil paint, if required, to produce a thin layer for a rapid blocking in stage. You may either let this initial coat dry or go over it with a thicker, oilier layer wet into wet. It does not matter which method you choose as long as you get enough layers down.
As you work on your painting, more and more medium will be needed to keep the paint from being too thick or too thin. As it gets darker, you will need less medium until finally, at some point during the final stages of your painting, you will want quite a thick coating of medium to absorb any underlying colors or tones that might show through.
The type of medium you use will depend on what effect you are trying to create. If you want your painting to be transparent, use water; if you want it to be opaque, use white lead (or a similar product). You can make your own media by combining different proportions of water and white lead. The more water you add, the thinner the resulting mixture will be. See how it affects your painting.
There are two types of medium: diluting and thickeners. A diluent reduces the amount of pigment in your paint by increasing its volume. Thickeners do the opposite - they increase the viscosity of your paint - so more of them is needed to achieve the same result.
Many layers of thick paint are used to create oil paintings. They do not dry like other paintings because oil paints react to air and oxidize and cure. As a result, they tend to dry from the top layer down, which takes significantly longer. Also, the more layers you add, the slower it will dry.
Oil paints are very durable. They can withstand heat, light, and moisture. This is why they have been popular materials for painting landscapes and historical subjects for centuries. Modern versions of these oils still use many of the same ingredients as their ancient predecessors. They just mix them in different ways than the old masters did.
When you roll over a ball with your foot, it's called "treadling" - preparing the surface by rolling it in a fine mesh sandpaper to remove any loose particles or gum from its previous application. This prepares the surface for the next step: mixing your own colors. There are two types of oil paint: tube paint and flat or panel paint. Tube paint is mixed at the source by adding pigments to a liquid resin base inside the container. Flat or panel paint is mixed on the canvas itself before it is put into the frame. Either type can be mixed in many different ways to create new colors that no one else has ever seen before!
As long as there is oxygen, oil will remain saturated with water.
Wet-on-wet oil painting is exactly what it sounds like: painting immediately on top of wet paint without letting the lower layer dry. As a result, the wet-on-wet process is often known as "direct painting." There are several advantages to this method include the ability to combine colors directly from the tube, minimize mistakes because you can't see the underlying color, and create new effects or changes in direction when working with thin layers of paint.
Some artists feel limited by the fact that they cannot mix colors on their palette before starting a painting. With wet-on-wet painting, they can simply add color to existing wet paint layers rather than mixing new colors for each painting. This method allows them to explore different combinations of colors and achieve looks that would be difficult or impossible with other painting techniques.
Another advantage of wet-on-wet painting is its durability. If you make a mistake while painting over wet surfaces it is easy to fix; just brush some more paint onto the area to cover up the defect. When using other painting methods, if you make a mistake you must either cover it up or start over completely. Wet-on-wet paintings can also be used as underlays - - another reason why this technique is popular among landscape painters. The image shown here was done using this method.
