A. New exterior stucco applied in Minnesota
new construction.
1. Upon positive exterior
sheathing inspection we begin by installing color
matching steel drip
edge over windows and doors, and should be 3/8 inch past the edges of each.
2. We install left and right hand
kickout flashings where rooflines meet an
exterior wall.
3. Next a 7/8 inch code-approved
weepscreed is installed at base of walls to have
stucco.
4. Application of 2 layers Grade”D”
felt paper overlapped bottom to top from the
weepscreed to the
soffit.
5. Installation of ¾ inch plaster
stop (casing bead) on bottom 3 sides of windows,
and sides of doorways.
6. Application of 3.4 psf
self-furring, galvanized, expanded metal lath installed
over paper.
7. Followed by corner aid.
8. Most
Minnesota cities require an inspection at this point.
9. Upon
approval our browncoat covers the lath. A mixture of Portland, mason,
fiber, acrylic additive, water and sand.
10. Installation of
cosmetic trim, keystones, quoins, etc. takes place now.
11. After 10-14
days of browncoat curing our selected finish coat can be applied.
B.
Restucco over existing stucco.
1. Usually
there is no inspection required for this process, although buying a permit is
still required.
2. First we
determine whether existing stucco is painted or not, there are several ways to
do this. One common way is to simply spray water on the wall. Stucco will
immediately darken, while paint tends to not change color. Also obvious
cracking and pealing is a very good clue. However, “whitewash” finish appears
darker when wet also.
3. After
careful viewing and preparing, sometimes patchwork is required where any damaged
stucco exists. Now is the time to address cracks.
4. The actual
restucco coating is a two coat process starting with a “brush” coat followed by
a dash coat. There are several color and texture varieties to choose from.
Usually determined on the start date of that coating.
C. Patching, crack repair and
color/texture matching
1. Visually
determine whether or not the cracking is worth fixing. If the crack is only
cosmetic and is not causing leaks/etc. we may recommend leaving them alone.
2. Some cracks
and patchwork need to be chopped out further into the existing stucco for a
solid adhesion of our new stucco.
3. If cracks
are caused by an addition to the existing home, we will install a manufactured
crack “expansion joint” to be visibly pleasing. ALL STUCCO AND CEMENT WILL
CRACK. Not all cracks are bad.
4. We will then
replace/repair the paper layer if needed for proper water shedding.
5. Application
of lath similar to above steps.
6. Application
of stucco basecoat. Generally flush with existing stucco unless the texture is
a “trowel texture”.
7. After
waiting 2 weeks a finish coat to match existing is applied.
8. It is very
common for the finish coat to appear much lighter for the first few months.
Slowly over time the finish will darken closer to the original picked color.
