Abstract
Some embodiments of the present disclosure relate to a method comprising: obtaining a base formulation, obtaining an activator formulation, mixing the base formulation with the activator formulation, so as to result in a liquid applied roofing formulation, applying the liquid applied roofing formulation to at least one steep slope roof substrate, and solidifying the formulation, so as to form at least one coating layer on the at least one steep slope roof substrate. Some embodiments of the present disclosure relate to a liquid applied roofing formulation comprising a first part and a second part. In some embodiments, the first part comprises the base formulation and the second part comprises the activator formulation.
