It is very difficult to flush out polyurea from your pumps and hoses sufficiently enough to run you foam through it. When I was General Manager at UCSC in the early 90s, we had a demo foam rig that we would use for both foam and polyurea. Eventually we got a dedicated unit for the foam and the polyurea because the flushing process was such a pain. With material costs so high for both materials, it is best to go with a 2nd rig unless it is a once or twice a year type of situation. As always contact your supplier for their recommendations on flushing the unit. |

Ok thanks. What proportioner would you recommend for small to mid size polyurea? |
