Traditional building elements<br />
should be maintained in order to<br />
preserve their integrity as characterdefining<br />
features. These elements<br />
could include, but are not limited<br />
to, masonry window sills, ornamental<br />
entry doors, cast iron storefront<br />
surrounds, masonry wall materials,<br />
window hoods and cornices. Surface<br />
cleaning should be undertaken with<br />
the gentlest means possible. Sandblasting<br />
and other harsh cleaning<br />
methods that may damage historic<br />
building materials are strongly discouraged.<br />
Waterproofing and graffiti<br />
proofing sealers should be used after<br />
cleaning and repair.<br />
<strong>Guidelines</strong><br />
v Abrasive methods such as sandblasting<br />
are inappropriate, as they<br />
permanently erode building materials<br />
and finishes and accelerate deterioration.<br />
v If cleaning is to be considered,<br />
use a low-pressure water wash.<br />
Chemical cleaning also may be considered<br />
if a test patch is first reviewed<br />
and negative effects are not found.<br />
v Repair deteriorated primary<br />
building materials by patching, piecing-in,<br />
consolidating or otherwise<br />
reinforcing the material.<br />
v Avoid removing damaged materials<br />
when they can be repaired.<br />
v If masonry has been painted,<br />
it may be preferable to continue to<br />
repaint it, because paint removal<br />
methods may cause damage to the<br />
building materials and finishes.<br />
