Incising

On treated wood used for structural applications (joists, beams, posts), you’ll see fine incisions on the surface of the wood that allow for better preservative penetration. Incising is the process of piercing the surface of wood with small slits, before treatment, to allow more preservative to consistently penetrate beyond the surface of the wood. Incising improves protection and lengthens the service life of treated wood. It also helps to reduce surface splitting by decreasing the surface tension. Incising is required to meet treating penetration requirements to provide sufficient preservative performance of structural materials.

For more information on which products should be incised see the MicroPro Sienna Residential Treated Wood Use Category Guide.
