MM38 Acrylic Thickener (Rheology Modifier) 250ml
An alternative to adding gels and other impasto or building mediums to paint which work by imparting their own thicker bulk to a paint mix. This medium actually chemically thickens the paint. It is a rheology modifier, that is, it changes the flow and viscosity of the paint, it will thicken the paint without losing any colour. Some colours may show a reduction in sheen in the dried film which can be adjusted with a varnish once dry.
Application / Use
Just add a few drops to the paint and stir in - it will need to be stirred in very well - use within 24 hours of mixing in - in case too much medium has been used and the paint thicken beyond a usable consistency. As a general rule 2-3 % should be enough to thicken the paint - any more than 5-7% (depending on the original viscosity) will not continue to thicken the paint but possibly start to thin it down again.
Each consistent of paint will require a different amount to be added to reach the same consistency and even within the same range and consistency - different colours may require differing amounts of medium. Compatible with all Matisse acyclic colours.
The thickness of application of this product will determine the length of drying time. For a thin coat, a standard estimation is 48hrs, but prevailing atmospheric conditions upon application may influence drying time (humidity, heat, cold, etc.). WARNING do not force dry or use in temperatures above 30℃ as premature skinning may occur trapping water in the coating resulting in an opaque or cloudy finish.
