You can use pressure treated wood in the making of furniture like kitchen tables and chairs , areas with high humidity. If you use them in the kitchen, for example, they will likely come into contact with utensils and so much more.
Pressure – treated wood should not be burned under any circumstances. The fumes can be toxic and the ash is very toxic . Do not use pressure – treated wood for making cutting boards, or for any food preparation surface.
Pressure treated lumber is no stronger than untreated lumber . The difference between the two is that pressure treated lumber will resist the elements better than untreated due to chemical preservatives added, and so will maintain its integrity in conditions that would cause normal wood to rot.

In addition, it also suggests that you not walk barefoot on a pressure – treated deck, and that children should not be allowed to climb on the treated lumber . Although the EPA maintains that CCA does not leach out of the wood , a recent study shows different results.
A: The safety of pressure treated lumber for raised bed gardens has been examined by several researchers. From what I’ve seen, the consensus is that the chemicals do leach out of the wood into the soil and are uptaken by the plants in very small amounts.
Because of the pressure -treating process, exterior paint is less likely to adhere to pressure treated wood and more likely to peel. Some experts advise staining or sealing over painting , but paint can be successfully applied by following extra precautions.
Pressure – treated wood is infused with chemical preservatives to help protect the material against rotting and insects. Termites can damage pressure – treated wood . This typically happens if the wood gets damp and starts to decay, or during construction.
A very safe process does exist to treat lumber , so it’s not so tasty to bothersome insects and wood -destroying fungi – although it’s rapidly being forgotten. You simply soak the lumber in the borate solution. Most people just build a trough using 6-mil plastic sheeting.
The National Tile Contractors Association and the Resilient Floor Covering Institute both recommend plywood for subflooring and underlayment , because it doesn’t have the risk of swollen edges that OSB does. Plywood also has a slight advantage in stiffness, which means that subflooring panels need not be quite as thick.
Poplar or Birch Plywood with a fully sanded face and exterior glue. Lauan Plywood, when used as an underlayment, should be Type 1 ( Exterior ). The best grade is BB and the next best is CC, while OVL (overlay grade) is the minimum acceptable face grade.
