Yield

Practical
6 - 7 m²/liter
Practical yield is a function of various factors, such as the structure of the substrate, the condition and shape of
the object, the application method, the experience of the applicator, as well as atmospheric conditions.

Systems

Pretreatment: see "Substrate conditions"
System with opaque primer for facades
One coat Sigma Façade Prim Aqua or Sigma Façade Prim Syn
One coat Sigma Façade Topcoat Matt
System with pre-treatment, Sigmafix Universal
Pretreat with Sigmafix Universal or Sigma Unigrund S
Two coats Sigma Façade Topcoat Matt
The number of finishing coats depends on quality requirements, the chosen shade, the existing shade and
the nature of the substrate.

Substrate conditions

Untreated substrates
Neutral, dry and cleaned to a sound, consistent substrate.
Pretreat absorbent or irregularly absorbent substrates with Sigmafix Universal (dilution according to
substrate, see data sheet 8205)
On porous, fragile and/or powdery substrates, fix first with Sigma Unigrund S (dilution with WhiteSpirit according to substrate, see data sheet 6020).
For further information on pre-treatment and/or fixing of walls and facades, see data sheet FI1333
Finishing an insufficiently dry substrate (still alkaline reaction) can cause clogging and in
extreme cases alter the paint.
Old coats of paint based on an acrylic resin dispersion
Good adhesion, sound and cleaned.

Application conditions

Ambient temperature and substrate temperature must be between 2°C and 35°C during
application and drying.
Relative humidity of max. 90%. Substrate temperature must be at least 3°C above the
rosing point.
Good ventilation during application and drying.

Instructions for use

Mix paint well before use.

Additional data

Adhesion
The adhesion of Sigma Façade Topcoat Matt is excellent both on mineral substrates and on high-quality
dispersion facade paints. Pre-treat very absorbent or irregularly
absorbent and/or slightly powdery substrates with Sigma Fix Universal (dilution 1:4).
Capacity
If matt wall paint is applied to easily accessible surfaces, scratches may be
produced by touch, or glossier marks may be occasioned by wash-off, flakes may
also remain. Mainly visible in darker shades.

Storage

12 months minimum in a dry, cool, frost-free place between 5°C and 30°C in its original
unopened packaging. Do not store in direct sunlight.
