Sorry you did not obtain the desired results you were looking for with this product's use. The adhesive is intended to be applied to new asphalt membrane or properly prepared and cleaned asphalt membrane. I would recommend checking to make sure the substrates were prepared and clean prior to using. KARNAK

          That is the nature of asphalt modified bitumen adhesive. The adhesive will get more firm over time as it is exposed to UV and heat. Asphalt gets pliable when heated as you have noticed, when the temperature goes us. It gets more firm as the temperature goes down. These are characteristics of asphalt roofing materials, and what makes them good products for keeping a roof water tight. Modified asphalt roofing products have very good expansion and contraction properties which helps them to adapt to weather conditions and stay monolithic to function as a roofing system. KARNAK
