In most cases, you can do this at home yourself. A valuable book that you have had for years you might want to take to a professional for repairs. Other basic tools include a square or a straightedge and a triangle, scissors, and brushes. Materials you will need include adhesives, cheesecloth, scrap paper for a gluing surface, and wax paper. Two types of adhesives are used for book repair, quick-drying white glue and slower drying flour paste.
White glue is used where permanent flexibility is desired.
Before using, thin with water until glue dripped from a brush back into container blends into the surface smoothly. Flour paste is used where flexibility is not required. Use unenriched wheat flour of fine pastry grade. Commercial wall paper paste is also recommended. Glue quickly, using largest practical brush for the job.
