Lascaux Medium for Consolidation is an acrylic dispersion with excellent penetration ability. Developed with the Swedish Heritage Board for the consolidation of paint in medieval polychromy on wood. Wide variety of uses.
Finely dispersed, aqueous dispersion of an acrylic copolymer.
●dries to a clear and flexible film
●light and resistant to age
●excellent penetrating power
●solids content: 25%
●MFT (Minimum filmformation temperature): approx. 4°C
●pH approx. 8.5
Dispersion dilutable with water. Film soluble in esters, aromatics, acetone, ethyl methyl ketone.
The Medium for Consolidation has been developped in cooperation with the Swedish National Heritage Board for the consolidation of paintlayers in medieval polychromy on wood.
The Medium for Consolidation has excellent penetrating power due to is low viscosity. This allows for the safe and efficient consolidation of loose and chalking paint layers, even on water sensitve surfaces such as gilding or thin layers of distemper. These can be consolidated without swelling or spotting on wooden or textile supports.
The concentration of the medium can be adjusted by addition of distilled water. Prior to application of consolidant white spirit can be used as wetting agent.
Excess medium of consolidation can be removed completely with aceton or yxlol after a drying time of approx. 24 hours.
The Medium for Consolidation has been succesfully used on various objects in numerous swedish restoration studios.
Keep containers closed, when not using the product. Store at constant temperature between 5°C and 25°C.
Undesired sediments which might appear during storage, can be strained with a filter before application.
