Artcare - B72 Retouching Gels

Painting large scale reconstructions using simple solutions of retouching media is a very difficult task. The applied paint thickens and dries too fast, making it impossible to work wet-in-wet or to apply glazes evenly over large surfaces.

The use of slower evaporating solvents for simple solutions of Paraloid B72 or PVAc helps only to a limited degree. Shellsol 100 used as a solvent for retouching/inpainting media evaporates at the same rate as Dowanol PnP (1-propoxy-2-propanol) used in the Slow B72 Retouching Gels. It is however easier to work with the Gels than with media based on simple solutions. The liquid crystal B72 Retouching Gels thicken more slowly as they tend to retain solvent for longer.

Very Slow - Light 10 Slow - Heavy 20

Very Slow - Light 10 gel with Dowanol DPM (dipropylene glycol monomethyl ether; 1-(2-methoxyisopropoxy)-2-propanol) has been especially developed to facilitate the painting of large scale reconstructions. It allows both painting wet-in-wet for a long period of time and glazing over large areas. It remains wet on the palette for many hours and so gives a similar experience to that of working with oil paint. If a higher concentration of resin is required it can be mixed with Slow - Light 20 gel and act as a drying retarder.

Paint containing Very Slow - Light 10 gel should be left for a few days to dry completely before overpainting, glazing and varnishing.
