What is PolyWhey Exterior Wood Stain Made Of?
The name PolyWhey comes from the key ingredient: whey protein. Whey protein is a by-product of cheese making and acts as a binder. It’s a renewable resource that translates to fewer VOCs than other water-based stains.
The spec and safety data sheets for PolyWhey Exterior Stain will show that it is not considered hazardous to plant or animal life. However, you should still wear basic protective gear and use it in a well-ventilated area.


Can PolyWhey Exterior Wood Stain be used near gardens?
As a non-toxic stain with no biocides, PolyWhey Exterior Stain won’t harm your gardens, and vegetables will be safe to eat. The wrong stain has preservatives that can soak into your soil or get on your grass or gardens, preventing them from absorbing water, nutrients, and sun. You might notice discoloration or see your plants wither away.
Will PolyWhey Exterior Wood Stain change the color of the existing wood?
Even the clear finish of “Caspian Clear” will darken your wood slightly and make the grain pop. PolyWhey Exterior Wood Stain comes in over a dozen colors to achieve a dramatic or natural look.
This may seem like an odd question for folks who use a stain to color their wood, but many folks LOVE the color of their beautiful cedar deck and don’t want it to change.
