Preparation
Strip any oxidized iron rods appearing on the surface of the reinforced
concrete until all rust has been removed. Use a sander to remove
the rust and apply immediately on the iron rods RIALTO UNIVERSAL,
an anti-rust protective product. Average covering capacity: 100
ml/m². Replace the iron rods whose section has been reduced
by more than 30% and weld new ones. Patch with the cement-based
mortar RIALTO WALLCEM, mixed with 10% of RIALTO MATONAL (max thickness:
0.5 cm). RIALTO WALLCEM average covering capacity: 1.2 kg/m²
per 1mm thickness. Allow the surface to dry completely before
proceeding. On friable and dusty surfaces, apply a coat of RIALTO
STABILIZER, a hardening and insulating primer based on acrylic
and petrol resins in a solvent. Average covering capacity: 160
ml/m². When the surface is completely dry, apply a coat diluted
to 25% with water of RIALTO FINISH, in the same color as the finishing
product.
Average covering capacity: 100 cl/m².
Finishing
Apply RIALTO UNIBETON, a leveling water-repellent non-yellowing
(as per UNI 8097 Regulations, no. 7 blue scale) product protecting
from the carbonation of reinforced concrete, based on water-based
terpolymer resins and UV ray-resistant pigments. Water vapor permeability
DIN 53122 Regulations: 55 g/m² - 24 hours, µ=2115,
Sd=0.42 m. Surface adherence not lower than 12 kgf/cm². Apply
two coats using a brush, a roller or a spray-gun, the first coat
diluted to 30-40% with water and the second to 20%. Allow at least
6 hours before applying the second coat.
Average covering capacity: 150 ml/m².
