Brian, I am curious as to whether you are aware of any original documentation confirming the use of lime-based limewash in original construction in either the roundhouse or the fort. As you are undoubtedly aware, both the 19th century railroads and the Third System seacoast fortifications were designed by engineers who considered lime a cheap extender, relying almost entirely on natural cement for mortar, concrete, stucco and yes, even whitewash that wasn't white. I have heard that some of the forts have been messed up lately by use of historically inappropriate and poorly performing lime and/or hydraulic lime-based mortars. Also, we have seen analyses of early 20th century mortars and stuccos that everyone assumed were lime because they were white, but they were actually slag cement.

Since it is clearly a sacrificial coating that is a first line of defense, I don't think that any savy person would use whitewash with the intention of it lasting years like paint. > > At the Roundhouse Railroad Musuem complex here in Savannah there is residual whitewash from the early 20th century everywhere. In that sooty environment they would just slap on a new coat every year as part of annual cleaning. The facility is considering reinstituting the practice to improve the visual interpretation. It is low tech, easy to apply and virtually idiot proof. > > At Fort Pulaski they used whitewash in the casemates where the guns were housed. They are also considering going back to the practice once they remove the WPA era portland cement repointing that is destroying the forts 50 zillion bricks. > > Brian > > ----- Original Message ----- > From: [log in to unmask] > Date: Wednesday, April 4, 2007 2:20 pm > Subject: [BP] whitewash > To: [log in to unmask] > > > Do people use whitewash any more?
