The field adhesion test is simply a hand pull test of a cut area of joint sealant. It is a very useful procedure for evaluating the effects of various cleaning methods and primers. It is also a good indicator of the fundamental adhesive properties of a sealant on a particular substrate.
We suggest that the contractor, or qualified specialist (see list below), perform this field test to assure that the proposed cleaning and preparation procedure is suitable for the existing conditions.
