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 two coats of RIALTO EPOCA OTTOCENTO, a decorative mineral
coating based on seasoned slaked lime, diluted to 20% with water,
repeatedly criss-crossing the brush strokes. Allow at least 24
hours before applying the second coat. Water vapor permeability:
430 g/m² - 24 hours (ASTM-E96 regulations), µ=140,
Sd=0.05 m. Surface adherence not lower than 30 kgf/cm².
Average covering capacity on fine plaster: 400 g/m².
