Auro 303 High Grade Natural Silicate Paint is a thicker, more premium version of the Auro 327 Anti Mould Paint

The problem solver for interior walls prone to mould growth. It has a fungicidal and algicidal effect thanks to its alkalinity.

Auro 303 Anti Mould Paint is a breathable paint and the ultimate problem solver for alkaline walls prone to mould growth, especially concrete and rendering, as well as gypsum plasterboard, clay or woodchip wallpaper. Thanks to its natural alkalinity, this high quality silicate paint has a fungicidal and algicidal effect, making it ideal for outbuildings.

A combination of potassium water glass and the biogenic binder Replebin® ensures professional grade quality. Auro 303 Natural High Grade Silicate Paint is highly water vapour permeable, free of preserving agents, and has certified class 1 hiding power, and wet abrasion class 2. This durable, permanently white paint is easy to use on evenly absorptive and smooth surfaces, where it can be applied without a prime coat. Irregularly absorptive surfaces should be primed Auro Plaster Primer No. 301, and uneven surfaces with the Grip coat No. 505.

  • Highly water vapour permeable
  • Permanent white
  • Solidification of the substrate
  • COVERAGE: 10m2 per litre

Large orders of big tubs will need to be sent on a pallet, so may be +1 or +2 working days. ECO PACKAGING: Testers use bio degradable corn starch infill packing pieces (these are only suited to testers and very light weight items though); on larger products we either use recycled/recyclable brown paper or we’re just starting to use pulped cardboard inserts for 2.5l and 5l tins - these are recycled and can either be recycled with household cardboard, composted or several people use them as firefighters!
