This viscus walnut liquid is perfect for wood stains. We have used it several times in our own home.
The photo to the left is a detail from the hearth we built last winter. We bought pine trim and applied the stain with a paint brush. The color is deep and unfading. The product is non-toxic, and even has a sweet nutty smell. It is a great alternative to chemical wood stains, which are harmful to breath in and use.
