A trick I used for many years thinning oil paint for landscape painting.
Thinning Oil Paint for Landscape Painting
Thinning paint for landscape painting so it is all of the same consistency
The paint should flow of the brush in a thick layer.
When painting landscapes wet on wet it is necessary to have all your colors at the same consistency ( viscosity ) or runnyness.
The method shown here for thinning oil paint for landscape painting is very useful if you intend to paint a lot using oil paints.
The messy and boring job of thinning oil paint is not always necessary.
A lot of oil paints are creamy and ready to use but if they are ‘stiff’ then that color will cause problems and should be thinned before you start a painting.
Acrylic paint in the student quality is usually at a good consistency to work with when it is new and fresh out of the tube.
Oil paint can be thick in some colors and just right in other colors.
Burnt umber is often at the right consistency when it comes out of the tube.
Different consistencies in your paint will cause endless problems with things like the brush picking up paint from the canvas instead of laying new paint down. The paint will not come of the brush.
Having the paint too thin can also cause problems. So think of the paint as a cream and not a liquid and it is placed onto the canvas in a creamy layer and not as a wash.
When thinning oil paint for wet on wet landscape painting do not use linseed oil
I don’t know why people buy linseed oil when painting.
To me it is useless, makes the painting blotchy with shiny spots and it is so slippery that the paint sometimes slips over the canvas and stays on the brush.
If you are dabbling the foliage onto your painting and it is doing nothing then you are possibly using a thinning medium which is linseed oil based.
The slippery linseed oil does not allow the paint on the brush to stick to the paint on the canvas.
So! it might seem unprofessional but kerosene is a great choice for an oil paint thinner. Try it.
Before attending a market and painting in public areas I always thinned my oil paint into plastic bags as shown here.
Two plastic bags, one inside the other is a good idea if the bags are of thin plastic.
Do take time to mix the paint in the bags well.

Here is the transcript from this video lesson about thinning paint for landscape painting.
If you intend to use oil paint then you need to prepare the paint using the technique of thinning.
You will not successfully learn to paint wet on wet with unprepared oil paint so please take the time to ensure that your paints are not too thick.
(the tube of paint shown in this video is a 45ml. sized tube)
I’ll show you a method now of preparing your oil paint ready for painting wet on wet.
Oil paint, is usually too thick when it comes out of the tube, and therefore we need to thin it.
A simple way to do this is use plastic bags.
You cut the bottom out of the oil paint tube and squeeze the paint into the plastic bag and you add your thinners, I’m adding fifteen mill of kerosene here.
You seal the bag and then mix your paint by rubbing it between your hands, you do need to mix it very well, if you don’t mix it well enough you’ll find that you have lumpy paint, which is okay but does cause some problems.
Then you snip the corner out of the bag with a pair of scissors.
When you mix it well your paint will be very creamy and that’s what we want.
If your paint is very thick and you try to use it with paint that is thin, you’ll find when you pick up the thick paint and try and brush it over the thin paint it will pick up the thin paint rather than lay the thick paint down.
So we need to have all our paints at a similar consistency, so they’ll flow off the brush.
Store these plastic bags of paint into a sealed container, a light proof container, don’t put them in a glass jar.
