Empirical use of Lascaux 360 HV as a lining adhesive indicates that bonds vary significantly depending on the effects of sizing applied on the original canvas and/or lining material, and on the amount of time between application of the lining with the adhesives (1 hour to 24 hours). In this research, bond strengths of linings were quantitatively measured by peel and lap/shear tests. Results confirm quantitative changes in peel and lap shear tests depending on the parameters chosen. Tables, graphs, references.
