Keim Ecosil-ME Interior Air Purifying Paint


Keim Ecosil-ME is a water based, solvent free, low VOC, non-allergenic and odourless paint for indoor walls and ceilings. It is ideally suited for decoration of interior areas, in particular for people with allergies.

KEIM Ecosil-ME is an internal silicate paint which optimises air quality, making use of photocatalytic pigments to reduce noxious gases and odours by transforming them into natural substances. This interior paint  neutralises noxious gases and pollutants, including industrial and traffic pollution, furniture and carpet cleaning solutions, cigarette smoke, formaldehyde, acetaldehyde, fatty substances and stearates.

It requires sunlight (or natural light bulbs) to activate the paint pigment to neutralise organic pollutants and odours, transforming them into small harmless components.

It is almost odourless during application making it ideal for areas where the relocation of occupants during decorating is impractical.

Drying time: Quick drying. A minimum of 5 hours between coats. 2 undiluted coats required.
Approx coverage: 8m² per Litre

Please note:  For previously painted surfaces and dry-lined surfaces Keim Ecosil Grund should be used as the first coat. Please see the general application guidelines below for more details.

Indoor air quality

The average person spends over 80% of their time indoors, yet more often than not indoor air quality is many times worse than it is outdoors. Pollutants from outside find their way into our homes and get trapped. Traditional paints, furniture household hygiene products and other VOC's (Volatile Organic Compounds) then add to the air pollution which we then breathe in. Keim Ecosil-ME Paint is a great way to reduce these pollutants, making your home a safer place to live.
