(not required for dry stack applications). The
following subparagraph will be kept depending on your choice from above.
*********************************************************************************************************
B.
Pigments:
Meeting ASTM C 979, mineral oxide type. Do not exceed color manufacturer’s limitations.

Moisture
Barrier:
*********************************************************************************************************
Select one of the following two subparagraphs.
Moisture barrier over sheathing is required by most codes. Option “a” is recommended by manufacturer as a positive means of stopping moisture migration
through wall and diverting free moisture to base of wall. Option “b” is a less
expensive product, yet still meets code requirements.
*********************************************************************************************************
a.
[Tyvek
Stucco Wrap, by E.I. Dupont, or comparable product as approved by Architect. Provide tape to seal joints, seams, and tears, of same permeance as membrane.]
b.
[ASTM
D 226, No. 15 non-perforated asphalt saturated organic felt.]
*********************************************************************************************************
Metal lath is recommended by manufacturer as a
base upon which to apply all stone products, regardless of substrate. Should installer wish to omit lath over
masonry and concrete substrates and use a bonding agent additive to the mortar
mix, consult manufacturer for recommendations on additives and mix proportions.
*********************************************************************************************************
2.
Metal Lath: ASTM C 847; 18 gage, galvanized, flat diamond mesh, self furring, stamped
a.
Attachment: Galvanized nails, screws and other metal
supports, of type and size to suit applications; to rigidly secure materials in place.
3.
Joint Sealant: Refer to Section 07920.
4.
Fasteners:
Coated 1-1/2 inch nails, staples, or screws of type and for spacing as
recommended by simulated stone manufacturer.
5.
Cleaner:
Nonacid cleaner as recommended by simulated stone manufacturer.
*********************************************************************************************************
Check
here if sealer will be necessary. Not required. However, if
installed on an exterior exposed to excessive water from runoff or improper
drainage, we suggest the product be sealed in that particular area to protect
it
from staining or spalling during freeze-thaw cycles. If sealer is necessary,
make sure to not only check the box, but also choose one of the options.
