Final answer:
When drymounting, the material being adhered should always be larger than the adhesive to prevent seepage and allow for adjustments.
Step-by-step explanation:
When drymounting, the paper or material being adhered should always be larger than the adhesive being used.
This ensures that the adhesive does not seep out from the edges and onto the artwork or document being mounted.
Having the paper or material larger than the adhesive also allows for any trimming or adjustments that may be needed after the mounting process.
