3M Spray Mount is a hugely popular choice of adhesive for professional artists and designers, most likely due to its adaptability. Spray mount is repositionable until dry – allowing for layout changes to be made and mistakes to be corrected a long time after the glue has been applied. Spray Mount can be repositioned for up to 12 hours when the adhesive has only been applied to one surface you wish to bond, and up to 2 hours when it has been applied to both surfaces being stuck together. Once dry, the glue forms a secure, long-lasting bond that will not brittle with age. This adhesive is transparent, so it can be applied without the worry of discolouring or staining your work. Spray adhesives offer a very convenient and tidy way of applying glue, but must be used with care – this product cannot be purchased by under-16s.
