AURO 117 Special Primer is recommended for use on woods rich in tannins, such as oak, chestnut and cherry. This product can also be used as a primer for Auro's original water based (Aqua) wood finishes. AURO 127 water based primer is not recommended for use on woods rich in tannins, such as oak, chestnut and cherry – as drying times will be extended. 117 Special Primer, which contains some natural solvent, is recommended in these circumstances.
Note: If you are using Auro's newer (Colours For Life) generation of water based wood paints (516 gloss, 517 satin), choose the Auro 510 paint primer, not the Auro 117.
