Characteristics of a good quality mastic sealant:

- May be multicomponent (mixing required) or single-component (no mixing required)
Typical uses for mastic sealants include, but are not limited to:

Natural or inherent problems:
Staining: Staining on the adjacent masonry where the sealant’s plasticiser has moved into the substrate.
Cohesive failure: deterioration of the intrinsic integrity of the sealant; cracking parallel to the surface of the joint is an indication of this type of problem.
Weathering: The deterioration of mastic sealants can be caused by lengthy exposure to ultraviolet light, water, and freeze-thaw cycles. Manifestations of weathering appears in the form of discolouration, chalking, softening or cracking.
