There are a few differences between these paints: 

• The Classic Wall paint no. 321 is wipeable (Class 3 abrasion resistant) whereas the Plantodecor 524 is highly washable (Class 1 abrasion resistant). Wet abrasion resistance is defined in DIN EN 13 300 and divided into 5 classes. Class 1 represents the highest rating of wet abrasion, class 5 the lowest degree of wet abrasion resistance. Busy areas which can get marked easy and require regular cleaning would be best to choose the Plantodecor 524.

• Both paints are very breathable but the Plantodecor 524 is more breathable as it has an sd value of 0.05 compared to the 0.1 of the Classic 321 Paint. When the term breathability is referred to with reference to paint it does not mean air, it means water, in liquid and gas form. Paints with high breathability enable moisture contained in building structures to be quickly released unhindered into the environment, avoiding things like flaking, dampness, and mould leading to a much healthier atmosphere.

• The hiding power or opacity is better with the Plantodecor 524 (Class 1) versus the Classic 321 (Class 2). This means the covering power is stronger with the 524.

Generally, there is no problem here. We do strongly recommend trying a sample area first just to be sure they are compatible as we do not know what paint was used previously. Tester pots are available on the website! A good option for difficult or unknown surfaces is to prime with the Grip Coat Primer 505.

Yes the Auro 321 can be used on all common plasters. Some plasters can be very absorbent therefore priming with the Auro Plaster Primer 301 can be a good option to go with to stop the new plaster soaking in all the paint. If using the Auro 321 directly onto plaster it must be thinned by 10% water. 

No. Auro paints do not have any plastics in their paints, Auro have developed their own plant based natural binder to use in their paint called Replebin. 

Replebin® is an innovative, biogenic binding agent, developed by Auro in a sophisticated research project that lasted over several years. Replebin® consists of plant alcohol ester with organic acids. The innovative binding agent is legally protected and available exclusively from AURO. 

Yes, this is certified as 'suitable for allergy sufferers' 

This product was tested by the Institute for Environment and Health (IUG). After an extensive analysis, all submitted products were positively evaluated because no allergens were found and the binding agent used constitutes no risk to human health. As a result, the IUG institute authorised Auro to use the product label ''suitable for allergy sufferers”.

Auro is a great option for anyone who has skin sensitivities, allergies, asthma etc... because Auro paints are made from natural materials with all the ingredients displayed you can see exactly what the paint is made from.
