Product Description

Internal and External Wood Primer for Oak, OSB and Hardwoods

Auro 117 is a solvent based wood primer and undercoat for internal and external tropical, hardwoods, osb and wooden garden furniture. It is biocide free and made from natural materials and minerals. Perfect for use throughout the home and garden.

Auro Special Woods Primer forms a slight film over the wood surface to reduce the likelyhood of bleeding and discolouration of subsequent coatings from active substances within the wood like tannins, glues, natural oils and dark pigments.

It is suitable for tropical, hardwoods and woods rich in active substances like Ash, Bangkirai, Red Cedar, Oregon Pine, Hemlock, Chestnut, Larch, Bamboo, Meranti (Dark Red), Merbau, Niangon, Pitch Pine, Framiré, Almendrillo (Cumaru), Jatoba (Paquio) and Teak.

Also suitable for OSB, MDF and Cork.

Certified as Toy Safe.
