Thinning her initial layers through a solvent method you don"t need to worry about violating the fat over lean ascendancy when adding subsequent layers of paint. The fat end lean ascendancy says that any kind of subsequent class of paint need to have actually at the very least as lot or much more oil content 보다 the previous great in bespeak to protect against sinking in. Sinking in is once dull spots show up on your painting after it has dried. Click here to check out my article on exactly how to fix sinking in problems.

The over consideration way that you have to only thin with mineral soul on her first couple layers that paint. Each additional layer should have actually less solvent than the ahead layer to ensure there is an ext oil in that new layer.
