Technical Qualities
MATERICO RILIEVO/RUSTICO by OIKOS is an exterior
coating formulated with both a medium grain as well as
a fine grain variation giving a gravelly plaster finish. The
product is composed of special acrylic resins in water
dispersion that give the product an exceptional resistance
to atmospheric agents, to acid pollutants, to UV rays and
to frost-thaw cycles. Grains of marble and sand in selected
grain sizes and high coverage, titanium dioxide based
fillers give the product great coverage and an elegant
aesthetic effect.
MATERICO RILIEVO/RUSTICO has excellent in-filling
properties and water repellence and maintains a good
level of vapour permeability of the support. Further to
this the product prevents the formation of mould and
algae; it is therefore indicated for the protection and
rennovation of all types of wall surface as well as for use
on thermal insulation facade systems. Should a greater
level of preventative action be needed with regard to the
formation of mould and aolgae, it is recommended to add
the indicated additive STERYLPLUS. The product has a low
odour level, is non inflammable and is friendly to both
humans and the environment.
Ideal Use
Exterior walls.
Surface Preparation
Surfaces must be thoroughly dry and mature, new plaster
should be left to mature for at least 30 days to allow
for the complete carbonatation of the support. Brush or
strip the surface in order to remove any loose or flaking
material; In the case of restoration works, water infiltrations
or leakages must be repaired before application.
Apply the indicated primer BLANKOR by OIKOS.
Wait 6 ÷ 8 hours before applying the finish product.
Application Method
Using an inox steel trowrl, apply an even coat of
MATERICO RILIEVO/RUSTICO with the thickness of the
coat dictated by the size of the grain of the product.
Following this, using the same tool, proceed to smooth
over the surface in circular motions.
