Product Description

Low VOC & Toy Safe Varnish (Gloss)

Auro 251 is a natural wood varnish for interior wood and wood based products. It gives a beautiful clear gloss finish with slight honey tone to furniture, toys and other interior wooden products.

This water based non toxic varnish is specially formulated to minimise VOC emissions without compromising on performance. It provides a beautiful, hardwearing finish with none of the harsh smells of conventional varnishes.

The low voc varnish dries clear, although has a milky appearance when applied. We recommend that you use Auro 127 Natural Wood Primer or Auro 117 Special Woods Primer (depending on the wood type) as this varnish needs a primer for correct finish. You can also dilute Auro 251 with a maximum of 20% water for a primer too for woods that are not rich in active substances - see technical data sheet below. When any kind of varnish is applied to wood it can affect the final colour due to absorbtion and other factors and using a varnish will help mitigate this.

Application is easy with either brush, roller or even spray. The final finish, when correctly applied, has a wipability abrasion class of 1 (the best) and will be scrub resistant.

Further Information:

Please note: This product is not suitable for floors or wood that comes into contact with the soil. It is for interior use only.

Natural products are neither odourless nor emission-free. 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, however they may cause allergic reactions in some. If you wish to know about what raw ingredients Auro use in their products please visit our Auro Raw Materials Guide.
