Description

• Mildew-resistant, acrylic dispersion-based, matte hygienic coating for interiors. Solvent- and plasticizer-free, emission-free.

Use

For painting on surfaces prone to mildew and algae formation. Ideal for industrial environments with high atmospheric humidity, such as bakeries, breweries, abattoirs, industrial kitchens, etc.
Can be applied to common household and workplace surfaces such as plasterboard, plasterboard, masonry, concrete, decorative plaster, glass-fibre fabric and well-adhering old coats of paint.

Key features

• Optimum resistance to mildew and algae
• Free from solvents, plasticizers and emissions (VOC < 1g/l)
• Applicable in food companies (certificate)
• Class 2 washability to EN 13300 and washable to DIN 53 778
• High covering power
• Very easy to apply
• Water vapour permeable
• For interior use only

Coverage

• Practical: 7-8 m²/liter
  The practical yield depends on 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.

Substrate conditions

General:
For long-term remediation, it is important to identify and remedy the causes of mould formation.
Eliminate any mould, avoiding the spread of spores. Then, if necessary, treat surfaces with an authorized active product.
Take the necessary precautions (e. g. protective gloves and goggles, mask, etc.).

New (untreated) substrates
Must be sufficiently bonded, dry (green indication on protimeter) and clean, until a sound substrate is obtained.
For mineral substrates max. 4% moisture content. For gypsum-based substrates max. 1%.
Finishing on insufficiently dry and hardened substrates may cause clogging (due to alkaline efflorescence).
Carry out repairs using lime-free products such as Sigma Enduit Exempt de Chaux.

Pre-treat powdery substrates with Sigmafix Universal (dilution according to substrate, see data sheet 8205).
Pre-treat very absorbent or irregularly absorbent substrates with Sigma Wallprim or Sigmacryl Prim Opaque.
For further information on pre-treating and/or fixing walls, see data sheet FI1333.

Old water-based substrates
Adherent, sound, clean with ammonia water and then allow to dry thoroughly.

Old alkyd paints
Adherent, sound, clean with ammonia water and then allow to dry thoroughly.
Remove alkyd paints by matt sanding.
