Both products, Eco-Safe Wood Treatment and Weathered Wood Finish are non-toxic and VOC-free. They both provide a stain effect that interacts with the wood to weather it naturally, while also leaving a patina, silvery sheen. They also both provide protective treatment.
So they are similar formulations tweaked specifically for their differing purposes.
Weathered Wood Finish contains more colour-enriching elements, allowing artists, designers, and crafters to be able to play with layering and deepening the stain, and also with detail work, while Eco-Safe Wood Treatment contains a greater ratio of protectant elements to colour-enriching elements, for larger projects like fences and decks that will have more exposure to the outdoors, because the Eco-Safe Wood Treatment is enhanced with UV and rain, which help with deepening colour and unifying coverage.
