The right fasteners

Using the wrong fasteners can be a costly mistake to your project. So make sure to use the right fasteners that are corrosion resistant to prevent any iron stains causing discoloration to your wood.

Why it matters

Iron stains are caused by the chemical reactions between the tannins in the wood and the iron contained in the nails, screws or fasteners.

By taking the time to choose the right fasteners, it can prevent unwanted discoloration or time consuming/costly fixes.

Uncoated steel nails or screws are the most common source for iron stains. It is best to avoid use of any poor quality fasteners. Even when using coated fasteners, iron stains can still appear if there are cracks in the coating.

Stainless steel fasteners are the #1 recommended fasteners for preventing any iron stains. This is vital especially when applying to the face of the product.

Other than nails or screws, iron stains can be caused by any abrasion from material containing iron such as steel wool, wire brushes or iron tools.

If you’re unsure of the types of fasteners you can use, your local experts or distributors are a great place to reach out to for more info.
