79 Foam - Day 3.5

No, I didn't get any foam sprayed yesterday or today. Sometimes you just need a day off from the heat inside that Tyvek suit. Other days there's other work to get done before you can continue spraying.

Until now I have been doing all my spraying from a ladder. While there are advantages to using a ladder because it is easy to move around, there are also disadvantages. As my metal roof is over 2x4 purlins (that run at right angles to the roof trusses), when you stand on a ladder you can generally only "see" one side of the purlin, the side facing the ridge of the roof. You can't reach the "backside" of the purlin without moving the ladder.

I solved that problem today by setting up stands so I could work from the walkboard instead of the ladder. It's set up with one end higher than the other, such that the walkboard parallels the slope of the roof. Now, as I work my way up the roof, when I reach a purlin I can spray the lower side of the purlin and then inch forward just enough to spray the other (upper) side. I'm thinking this will make for a better appearance and more uniformity in the foam layer.

I should have done it this way all along, but sometimes we opt for an easier, even if less desirable solution. What's that old saying, if you don't have time to do it right, when are you ever going to find time to do it ...over.
