Lascaux Retarder
Added to acrylics Lascaux Retarder extends open time without
altering the quality or the aspect of the colour. Not suited for works on absorbent substrates or outdoor use.
Video: how to use Lascaux Retarder
- doubles open time
- does not affect the quality and aspect of colours
- only minimal changes to viscosity
- lightfast and age-resistant
- pastose and very economical
Use & application:
- as an additive to acrylic colours on non-absorbent substrates
- only for indoor use
Lascaux Retarder Ultra
Added to acrylics Lascaux Retarder Ultra extends open time sixfold without altering the quality or the aspect of colours.* Not suited for works on absorbent substrates or outdoor use.
- extends open time sixfold
- does not affect quality and aspect of the colour
- only minimal changes to viscosity
- lightfast and age-resistant
- pastose and very economical
Use & application:
- as an addition to acrylic colours on non-absorbent substrates

Lascaux Thickener
Lascaux Thickener increases
consistency and viscosity of highly diluted colours, and preserves spreadability.* The thickening effect is displayed only in wet colours.
- increases viscosity of acrylic colours
- conserves the water balance of colours and extends open time
- ensures good brushability for glazes with highly diluted colours and prevents trickling
- colour depth and surface remain unaltered
Use & application:
- for thickening highly diluted colours
- only for indoor use
Lascaux Matting Agent
Adding Lascaux Matting Agent to acrylic colours will
increase their mattness level and covering power, similar to gouache or tempera colours.
- increases mattness and opacity
- dries to form a matt and water-soluble film
- lightfast and age-resistant
- free of binders
Use & application:
- acrylic colours and mediums
- for aqueous systems only
- only for indoor use
Lascaux Acrylic Emulsion D 498-M

Lascaux Water Resoluble Medium
Lascaux Water Resoluble Medium is a bonding agent designed for creating water-soluble
colours such as gouache or watercolours.* It dries to yield a water-soluble and matt finish and can also be used as a painting medium for Lascaux Aquacryl and Gouache.
- increases yield
- colourless
- dries to form a water-soluble and matt finish
- lightfast and age-resistant
- improves the brushability of diluted colours
- does not alter gloss levels when added to Lascaux Aquacryl or Gouache
Use & application:
- as a binder for the preparation of water-soluble colours
- as a medium for gouache and watercolours
- for retouching
The viscous, transparent Lascaux mediums allow changing gloss levels as well as increasing the transparency and yield of colours.
Lascaux mediums increase transparency of colours, and they increase the adhesion and film strength of strongly diluted colours. They also improve spreadability. Hue and viscosity remain unaltered. All Lascaux mediums contain pure acrylic dispersion and are therefore extremely lightfast and age-resistant. Lascaux additives increase the scope of colours.
