Such an awesome treat in so many ways!

What does it mean "Fat over Thin" or "Fat Over Lean"?

Ah, great question!  What does it mean Fat Over Thin, also often referred to as "Fat Over Lean" - when I first learned how to oil paint I thought it meant to keep the paint thin until you are ready to lay on the paint thickly.  It seemed logical, right?!

What fat over thin is referencing to is the amount of linseed oil or binding agent (aka Fat) that is in the paint.

Why should we keep it "Fat Over Thin"?

It is important to be aware of the amount of fat that is mixed with the pigment because the amount of "fat" to pigment ratio determines the speed the paint dries.

So let's chew on that fat for a minute 😁🎨 (painting pun intended); the paint dries at different rates due to the amount of oil to pigment ratio.

The more fat, the longer it is going to take to dry.  If you put the fat first (which you are not supposed to do), then the paint on top of the fat paint may dry faster than the paint below and BOOM! You have cracking and flaking of the paint over time!


Avoid cracking oil paint by adhering to the rule "Fat Over Thin" also called "Fat Over Lean".

Proper Oil Painting Technique to Adhere to the Rule "Fat Over Thin"

Here is what you want to happen to avoid cracking:

1st Layer = Thin the paint with Gamsol; this will reduce the amount of Fat (aka oil) in the paint and enable the paint to dry faster.  This is keeping the paint thin (aka lean).

2nd Layer = Increase the oil content by adding a medium like Galkyd fast-drying medium

3rd Layer (if needed) = Increase the oil content by continuing to add Galkyd and alternate with Neo Megilp when you need or want to glaze.

Final Layer - Increase the oil by adding Solvent-Free Gel to the paint and get a fabulous shine to the oil paint and thick, gorgeous brush strokes.

Here is a link to all the products that I use for my oil paintings and after 20+ years of painting, not a single one has cracked because I adhered to the rule of "Fat Over Thin"
