Thank you for your posting your feedback and for your interest in the DAP Touch ‘n Seal/Touch ‘n Foam products. The Touch ‘n Foam Pro System 15 Kit, as with all two components spray polyurethane foams must be used within narrow temperature ranges: "CHEMICALS (70° - 90°F/21° - 32°C), SURFACES (60° - 90°F/16° - 32°C), AIR (60° - 90°F/16° - 32°C). Achieving the full product yield is predicated on proper application ratio, temperatures and application technique. Even small variations in these factors can significantly impact the product's coverage rate. While one component spray polyurethane foams can be applied in a wider temperature range, they are not appropriate for large void/cavity filling and do not offer the same R-Value or vapor barrier performance. Because you did not provide any background on your application technique, application conditions or project background, it is not possible to provide a more detailed response in this format. At your convenience, please contact DAP’s Technical Customer Service Department at 888-327-8477 so that we can obtain some additional information regarding your experience.
