The Auro Ecolith 343 is a purely mineral paint suitable for interior and exterior use. It is a premium quality lime paint which is highly washable and can be used on numerous surfaces including over conventional plastic paints. Due to its high alkalinity and breathability it is particularly resistant to mould. It has zero VOC emissions.

Please note it is not suitable for use over natural resin based paints. It is very easy to apply and it has excellent coverage, it can cover approx 16sq/m per litre on smooth surfaces.

What it does

It provides a very hard wearing surface for your walls and ceilings. It is a beautiful matt finish which is extremely abrasion resistant and breathable.

Installation Guide

The product must first be diluted with 10% water. It is not ready to use until this is done.

Suitable for all interior rooms, including kitchens, bathrooms and nurseries, older properties with potential damp problems. The paint can also be used on plaster, clay plaster, lime plaster, concrete, reworkable old coatings, e.g. dispersions, lime, mineral paints, also plastic- based dispersions. The paint cannot be used over natural resin-based paints.  We recommend a test area to ensure compatibility prior to carrying out the job

Highly absorbent interior new plaster should be primed using Auro Plaster Primer 301.

If unsure what the surface is or it is a poorly absorbing or difficult surface, we would recommend priming with Auro Grip Coat 505 It is re-coatable after 6 hours.

For unpainted exterior surfaces we recommend to prime with the Auro Grip Coat 505 before applying the Ecolith. It can be used directly onto intact, plastic based paints without priming. When using externally, the painted surface should be protected from heavy rainfall for 4 days after painting. 

The paint has excellent coverage –  up to 16sq/m per litre and is very easy to apply by brush, roller or by spraying.
