We are sorry you were disappointed with the coverage you obtained while using the 200 board foot foam kit.
It is very important to follow all of the preparation and application directions. Spray foam coverage is very dependent upon ambient, substrate and chemical temperatures. Application technique can also affect coverage.
The most common causes of reduced coverage are cold substrates and not allowing 2 - 3 days for the chemicals to warm up to a proper temperature prior to application. During the cooler months (October - March) the chemicals in foam kits will be below the minimum when purchased. So projects should be scheduled taking this 2 - 3 day warm up period into consideration.
Excerpt from the instruction sheet:
Cylinders and contents must be brought to between 70°–90°F (21°–32°C) for use. This normally requires 36 to 72 hours at room temperature. Application at higher or lower temperatures may reduce foam performance.
For best results, ensure that chemical, ambient and substrate temperatures are 60°–90°F (16°–32°C) before and during use.
If you have any additional questions, we encourage you to call Technical Services at 800-325-6180 ext 14064.
