STUCCO is a skin of the house. It must breath, but it shouldn't leak and crack.
KALMATRON® KF-A is an admix to the stucco mix which produces zero shrinkage
cracks and is impermeable to liquids of one step applied coat.
It takes 2% of KALMATRON® KF-A admixture from the weight of cement to get
one-step applied coat benefited by:
Proven economy per 1 SF is at 40% of shotcrete and gunite applications
comparing to the standard stucco coat installation will benefit any project.
Largest repair project in California is still going on from 2005 by coating of inner walls of famous 100 years old Mojave
Aqueduct (www.shieldcrete.com). Los Angeles Water & Power Department is very satisfied with conformity of non-
shrinking performance and water/crude oil impermeability by ¾” plaster layer based on Kalmatron® KF-A.
Slump is at 2 1/2" with pumpability up to 500' without Plasticizer.
Vertical shotcrete spay with KF-A has no rebound
with immediate adhesion to the ceiling.
Stucco batch with KF-A performs Creamy Effect at W/C = .42 or less
Finishing by the screed without trowelling after.
Fresh cut of 2 1/2" deep coat applied by one pass.
Batch Creamy Effect results in higher viscosity of fresh
coat surface. Left trowel on a wall and it stays on it.
It is a vivid indication that coat doesn't need to be water
sprayed or covered by film for curing.
One step applied stucco has higher density and much
more durable than traditional multi coats hiding
shrinkage cracks being triple more expensive per S.F.
Plastering in California means working under ambient temperature at 100 F and dry winds where
KALAMATRON® KF-A is only the solution. It reduces exothermic heat and speed of moist evaporation
from the coat surface to guarantee zero shrinkage cracks to the customers. And of course, to save
money on scratch and brown coats, cracks patching, curing, labor and transportation back and forth.
