Winter Blends
Anybody tried spraying winter blends in the summer. What might be the repercussions’ hard to spray, can't be sprayed, bad foam that might have to be removed, etc.Thanks |

Winter blends have a faster reaction time. Typically results would be a lower density foam, blowholes and pinholes in the foam, rough, popcorn type surface profile and a pattern that is very hard to adjust. Also the foam would have a higher exothermic heat reaction within the foam during its rise and initial cure time, could lead to problems down the road (poor cell structure, cracks, fissures and foam shrinkage) |

thanks for the info, looks like a gamble not worth taking. I'd hate to have to dig bad foam out of a roof 25' up. thanks again. |
