Preparation
On a new sound plaster or on old surfaces leveled with RIALTO
WALLCEM, apply one coat of the absorption-regulating, water-repellent,
anti-saline efflorescence RIALTO ISOCAL primer, based on an oligomeric
organosiloxane. RIALTO ISOCAL average covering capacity is 0,4
l/m². On a new dusty or friable plaster, apply one coat of
the water-repellent, anti-saline efflorescence RIALTO DURASIL
single-can hardening primer, a colorless solution, based on water
and an alkysilane emulsion. RIALTO DURASIL average covering capacity
is 0,3 l/m².
Finishing
Apply, using the technique for stucco with spatula effect, three
coats of RIALTO EPOCA SPATOLATO, a mineral coating based on seasoned
slaked lime and mineral oxides. The first coat should be a thin
layer applied using a stainless steel trowel, so that the speckling
effect of the sand remains visible. Allow at least 24 hours before
applying the second coat. Water vapor permeability: 430 g/m²
- 24 hours (DIN 53122 regulations), µ=80, Sd=0.05 m. Surface
adherence not less than 30 kgf/cm².
Average covering capacity: 1 kg/m² for three coats. Protect
from rain for at least 48 hours.
