How often is maintenance required for thermally modified wood products?

Thermally modified wood products have increased dimensional stability which allow it to maintain its size. This ensures the products will not shrink or swell following the application of a protectant. When the product maintains its size it prevents the finish from cracking, which means less coats, less often.
However to ensure you are receiving the best results from your protectant please follow the directions on the products’ label.
