Auro High-grade Clay paint is the first ready-to-use clay paint on the market that has no preservatives at all (No MIT, BIT, thiazoles). It is highly breathable so especially suited for areas where moisture can be an issue.

Where to use it

The Auro High-Grade Clay Paint 331 is Auro’s most breathable matt finish and unlike most conventional paints the paint does not contain any synthetic ingredients or plastics. The Clay Paint can be used over all normal interior surfaces such as plaster, clay, concrete, sand-lime brick, gypsum plaster boards, wallpaper, brick, lime plaster, old coatings able of wetting. It is suitable for all rooms in the house especially suited to areas which are exposed to a lot of moisture. It is the very first ready-to-use clay paint on the market that has no preservatives at all.

This paint is available in white (slightly off white) if you want a colour in the clay paint check out the Auro High Grade Clay Paint 535 and choose from the largest range of ready mixed natural paints available in Ireland.  

Available in 100ml sample pots, 2.5 and 10 Litres

What it does

The Auro High-grade Clay paint is moisture-regulating and breathable which means it can hold moisture but will not trap it which makes it suitable for all living areas such as bedrooms, bathrooms and kitchens.

The Clay paint helps to regulate the indoor climate and thus contributes to a sense of well-being. This is great news for anybody who suffers from allergies or sensitivities.

It has an abrasion resistance (class 3, DIN 53778) and opacity (class 2).

Why we love it

It is rated as A+ by the Agbb (Health – related evaluation of Emissions of Volatile Organic Compounds). The use of organic, natural and plant-based ingredients means that allergy and asthma sufferers and people who are chemically sensitive are much more able to tolerate Auro products and all ingredients are disclosed.

This product is a vegan friendly paint and impressively the paint is fully compostable.

The finish is a fine and smooth coating because the light clay used in the product is not granular or sandy.

How it works

The paint does not trap moisture as it does not contain any plastics (acrylic, vinyl etc…). Paints containing plastics can trap moisture within your walls leading to problems such as damp and mould growth. Our paint enables your walls to breathe by allowing moisture to escape. Great for bedrooms where it can store the humidity during the night and then release it again into the air.

Can I get Clay Paint in Colours?

Certainly, please check out the Auro High Grade Clay Paint 535 or contact info@auropaints.ie to have a colour chart sent out or get more details. 

I am looking to use this paint on lime plaster walls but I also have internal gypsum plastered walls, can this paint be used on both?

Yes the Auro 331 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 331 directly onto plaster it must be thinned by 10% water.

Is the Auro Clay Paint safe to use in children's bedrooms?

Absolutely yes. All ingredients are declared on on the product and as you can see this is a safe paint, non toxic with zero VOC's. It is made from natural ingredients. The Auro paint range are all very safe to use. 

My child suffers from a lot of allergies and sensitivities and I am looking for a safe paint for her?

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.  

Is this product suitable for allergy sufferers?

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”.

Installation Guide

Suitable for all interior rooms, including kitchens, bathrooms and nurseries, older properties with potential damp problems, newly plastered walls and painting over previously painted surfaces. (We strongly recommend a test area to ensure compatibility prior to carrying out the job). The paint can also be used on wallpaper, plaster, clay plaster, lime plaster, concrete and brick. The paint can be used on new plaster by thinning the first coat of paint by 10% with water. Another option best suited for priming highly absorbent surfaces (like gypsum) is the 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 4 – 6 hours. The following coats should be applied unthinned. A previously unpainted wall will generally need one primer coat followed by two un-thinned coats. Painting over a previously painted wall two coats is generally desirable. When painting over a previously painted surface it is important to try a test area first to make sure it is compatible.

The paint has excellent coverage – 9sq/m per litre and is very easy to apply by brush, roller or by spraying.

All ingredients are fully declared on the tin and in the data sheet. It does not contain any oils so will not yellow and emits very little odour during the drying process.
