Steve Law Posted: Sep 19, 2007 04:21 PM	Roofing overspray control. Hello, I am doing my first roofing job this week and it is an apartment block roof with other buildings faily close by. I am worried about overspray of foam and polyurea top coat. The job is not big enough to buy a mobile spray booth but I was hoping someone has some ideas for containing overspray as the chances are it will be windy. I thought of constructing a 10 feet by ten feet u shaped frame about 3 feet high, lined with that shadecloth /wind break mesh and having my guys move it around for me. Any ideas or links to photos would be appreciated. I realise proper tip selection and technique will help reduce overspray.

Spray screens of all shapes and sizes sure can make you look like a pro, but nothing is going to stop the fine mist from making a nice mess on the Beemer parked just across the street. Just as you can't spray in the rain or in high humidity or within a few degrees of dewpoint don't chance spraying if your not sure if its too windy. Weather certainly is the biggest obstacle to overcome with spf roofs. Its a shame, spf roofs don't have very many downfalls, the weather is certainly the biggest.
