On the spot treatment prevents metal staining on wood during construction.

Vancouver, February 7, 2011 - Metal staining is a reaction on the surface of wood to the presence of ferrous metal residue from tools, handling and construction. It can appear as dark spots, often under the surface of the final finish, which clients sometimes report as a fungal attack.
 
Metal staining can happen at any time during log or timber construction, when minute metal particles are deposited by bandsaws, chainsaw sharpening or metal blade cutting or grinding elsewhere on the jobsite. It can even be something as small as handling the wood after you’ve worked with metal, or laying a chisel on the surface. The metal then reacts with the wood, or the finish, creating dark grey, bluish or black spots.
 
Before proceeding with any kind of stain, especially a water-based or water-borne finish, it is important to reduce the chance of metal staining occurring.
 
We recommend a 3-step process, to remove existing staining and /or to greatly reduce future staining, prior to shipping the shell or frame:
 
  1. Refresh the surface of the wood with a wood restorer, such as CBR Products X-180, or sanding. This will remove any oils, dirt or residue and opens up the wood cells for better penetration..
  2. Apply an application of CBR IronShield, or an equivalent. IronShield reduces the chance that the metal particles that are in the wood or may land on the wood will oxidize and leave a black stain.
  3. Apply a coating of BRODA® Yard Treatment or an equivalent for water repellency, UV resistance and fungal protection.
 
This process works well as the last step before packaging or shipment.
Now you or your clients will be able to use any low-VOC coating to protect the wood, such as our BRODA® PRO-TEK-TOR water-borne natural oil or BRODA® CLARITY water-based acrylics, with a greatly reduced risk of metal staining.
