(a) A term used to describe the thickness of a paint in the can.  While paints of thick consistency are usually expected to be difficult to spread, this will not be the case with ‘Gel’ and ‘Thixotropic’ paints.  Paints can be brought to a lighter consistency by thinning.(b) The resistence of a paint to flow.  A paint with a high consistency flows slowly; with low consistency it flows readily.
