Asphalt roof - how much cleaning do I need to do?
I am getting ready to apply a new elastomeric roof coating on top of the
existing asphalt membrane. Instruction says to thoroughly clean and let dry before application. The problem is the asphalt membrane has a lot of "loose" particles the size of sand. I think it's part of the asphalt that is coming loose? I am unable to clean them off totally. I can brush and brush and brush and more come out and it seems to never end. Any suggestions? May be I should just apply it as-is? Thanks, MC |

Any suggestions? New coating should be at least 3 times as thick as the largest loose particle. |

Thanks aem, I was using a push broom, and the more I pushed the more loose particles I got. So I didn't need to do all that? Oh well. MC |
