(a). Substrate must be Brown Coat Stucco or Base
Coat Stucco
with a minimum cure period of 48 hours. Irregularities should
be less than 1/8 thick and surface should be clean, dry, and
free of oil, grease, dirt and loose materials.
(b). ResinKast® architectural elements are manufactured using a
proprietary high-density resin system. Elements can be
designed solid or hollow, depending upon size. A reinforcing
fiberglass mesh flange (patent pending) extends along the
edges of each element. This reinforcing mesh is an open
weaved treated glass fiber, with a weight of 4.3 oz / square
yard and tensile strength of 150 PSI. One side of the mesh is
continuously embedded into the resin with 4 minimum
penetration; the other anchor extends out by at least 4
along the edges. Embedded anchor tabs every 16 allow for
weight support distribution to accommodate adhesive curing.
(c). ResinKast® products are shipped with a primer base coat
finish that will accept any final coat of paint.
(d). Apply a PL Premium Polyurethane adhesive manufactured by
OSI or equivalent to the entire area of the ResinKast® element
that will come in contact with the wall for hollow trims, and
apply a minimum 1/4 bead every 2 for solid trims.
(e). Connect ResinKast® elements to wall surface by pressing
glued surfaces of the trim to wall surface. Hold in place for 1
to 2 minutes. If the adhesive is insufficient to support the
ResinKast® element, use mechanical fasteners inserted
through anchor tabs for support until adhesive is cured.
Mechanical fasteners shall be 3/16 or 1/4 tapcon anchors
with corrosion resistant coating or equivalent and with 1 1/4
minimum penetration. Allow a minimum of 24 hours to cure.
(f). Thoroughly mix 1 to 1 by weight of Portland cement Type I or
II and a polymer based product. Allow the mixture to set for 5
minutes.
(g). Apply one coat of the Portland cement mix on wall surface
underneath reinforcing mesh using a stainless steel notched
trowel. Fully embed the reinforcing mesh in the wet mixture,
troweling from the trim to the edge of the reinforcing mesh
so as to avoid wrinkles. The overall minimum Portland
mixture thickness shall be sufficient to fully cover the mesh,
with an approximated minimum thickness of 1/4.
(h). After the Portland mixture is cured a minimum of 24 hours,
apply a coat of stucco finish over adjacent wall and over the
reinforced mesh area previously covered with the Portland
mix up to the edge of the ResinKast® trim using a stainless
steel trowel and floated to a desired texture. Air and surface
temperature for application of mixture must be 40 degrees or
higher and must remain so for a minimum of 24 hours.
(i). When joining two pieces of ResinKast® products, 1/8 to
1/4
space should be allowed between items to accommodate
expansion. The joint to be sealed to a depth of at least 1/4
using, as necessary, backer rod and H2U Acrylic Urethane
Sealant, manufactured by OSI or equivalent.
