Pressure-treated wood is a staple of the Canadian backyard. But there a few need-to-knows when working with it.
1. New pressure-treated wood is corrosive to steel. This means special fasteners should be used- stainless steel or copper are ideal. Galvanized steel fasteners can be used but be sure they are labelled - for use with pressure-treated wood.
2. Before you buy, be sure the wood has the preservative treatment that matches how you'll use it. Some pressure-treated wood is tagged for above ground use only.
3. Wear protective gear - the wood is chemically treated so slivers or sawdust can be dangerous.
4. Never burn pressure-treated wood, it's toxic. Dispose of it properly.
Before you begin an outdoor project, "yes" -even a deck, check if building permits are required.
