Consolidation process is considered one of the most important step in wood conservation treatment, and there are different materials used as a Consolidant materials such as Nano-restore is a highly compatible with carbonate based materials such as calcareous substrate, plasters, wall paintings and carbonatic stone, Nano-restore also achieving a good results and good re-adhesion of detached pigment flakes without any side effects. Klucel E, furthermore, is one of cellulose ethers (CE) which are widely used as a adhesive materials for wood and paper artefacts. Wherefore this study stablished to evaluate the effect of both on the consolidation of painted wood. different analytical methods such as FTIR and Color meter have been used in the assessment to determine the Chemical alteration which accrue to painting layers, plasters of lime and gypsum and to the wooden base.

the two consolidant materials, klucel E and Nano-restore didn't effect on the visual appearance and chemical composition of the wood, ground layer and colors and also didn't caused any color change.
