We had big problems of the water drying on the glass today for some commercial work where the windows were in the sun.
I did the windows inside of one place and no matter how wet the mop, it was dry in under 10 seconds.
One place we do is hundreds of 6 inch square paines on a large flat roof ( and it cannot be done with wfp) and I was hopping from foot to foot because the roofing felt was so hot. Mix that with a white wall reflecting the sun and it was hell.
At 2.30pm we just gave up. I cannot remember us stopping work before because of the heat.
Also, I have never ever drunk 6 ltrs of water in a day before and I can never remember getting my face sunburnt. I'm also knackered.
Trouble is with starting very early is for us at least, we are dependant on getting access for some jobs and for a number, it's important that the various managers or who ever see the work being done. Mix that with the logistics of getting around to all the work.......
Cheers
