Auro 301 Plaster Primer
Low VOC Primer
Auro 301 Natural Plaster Primer is designed for priming absorbent or uneven bare plaster before painting. Ideal for use on gypsum plasterboard and gypsum fibreboard and mineral interior plaster.
Materials which are highly or unevenly absorbent, such as gypsum plasterboard, should be pre-coated to achieve a uniform painting result. This avoids uneven, dull patches on the walls.
The best primer to use before applying dark colours onto new plaster. Auro 301 is a highly breathable primer, so ideal in older buildings or and before painting with lime based or other breathable paint products.
This non-toxic primer has a milky appearance that dries transparent. This is a concentrate that you dilute 1:1 with water before use.
People with allergies or who are MI sensitive will be happy to know that, thanks to Auro's ecological choice of raw materials and compliance with the strict AgBB criteria on emissions (a German evaluation scheme for VOC emission from construction products), this product is a designed to be suitable for allergy sufferers.
Apply with a brush, roller or spray.

Please note: For an interim period, the older version of the Plaster primer no. 301 may still be available in retail. The new formula product can easily be identified by the REPLEBIN® icon on the label. Due to the different binding agents, the two versions must not be mixed together.
*Replebin is an innovative, biogenic binder. It has been developed by Auro throughout a long term and complex research process. Replebin consists of plant alcohol esters with organic acides. This modern binder is legally protected and only available at Auro.
Natural products are neither odourless nor emission-free. The use of 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, however they may cause allergic reactions in some.
