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 a stainless steel trowel, RIALTO ANTIQUA type "2",
a colored mineral plaster based on selected seasoned slaked lime,
mineral aggregates with different granulometry and alcali- and
UV ray-resistant pigments. Finish off with a wet sponge trowel.
Water vapor permeability: 582 g/m² - 24 hours (DIN 53122
regulations), µ=45, Sd=0.06 m. Surface adherence not lower
than 10 kgf/cm².
Average covering capacity on leveled coarse plaster: 2.5 kg/m².
After 24 hours, using a brush and starting from the bottom and
working upward, apply to fully saturate the surface a coat of
RIALTO SILAN, an absorption-regulating, colorless, transparent,
breathable water-repellent treatment based on oligomeric siloxane
alkylates.
