MicroPro Sienna® Treated Wood uses innovative micronized pigment technology to give the wood a warm natural tone that enhances its grain and natural characteristics. Designed to meet the style demands of indoor/outdoor living, it offers a rich, finished look that complements today’s deck furniture and furnishings with no initial staining.
In an exterior project, the colour of MicroPro Sienna will turn to warm tan and over time will gradually fade to driftwood grey. The length of time will vary according to the exposure to sunlight, the wood species and the application. To maintain the colour and surface of MicroPro Sienna Treated Wood it is recommended that a high quality water repellent be applied to the wood as soon as possible after construction of the project. Long term, the initial colour will provide a good foundation for staining to renew or change the colour. See Finishing for more information.
It is possible that on some MicroPro Sienna treated wood a green colour may appear along the grain of the wood and around knots. This green colour is due to the copper that is used in the wood preservative system. Over time the green colour will change to a tan colour that blends into the overall tone of the wood.
A colour-matched sealer for pressure treated wood, Cut-N-Seal® is available to cover cuts and holes above ground and to retouch any blemishes during construction of the project.
Products treated with the MicroPro Sienna pigment colouring system are resistant to fading but are not impervious to colour changes. Natural colour variations in the product are to be expected due to varying exposure conditions and the variation between different species of wood. In addition, colour variations may occur between heartwood and sapwood and knot areas from board to board or within the same piece of wood.
