Clear Finish & Stain Information

StairSupplies™ offers several premium stain and finish options for our products, depending on the product’s use. For Stair Trim, we offer both clear finishes and stains. Select a clear finish if you want to draw out the natural beauty and colors of the wood. If you prefer deeper, richer tones, our custom-mixed stains are the ideal choice for your Stair Trim.

All tread materials and products that are used underfoot are finished with a Conversion Varnish. Strong and resilient, this varnish is standard in the hardwood flooring industry. Our team of experts apply this specialty product onto each stair tread using a spray applicator for even, flawless coverage to protect your treads and trim against heavy wear and tear.

Wood Grain & Color Variation

At StairSupplies™ we believe that natural wood colors and visual textures add character to our products. With that in mind, we strive to match the grain and color of all of our wood products as closely as possible. However, due to the natural variation of wood products, there may be instances in which a perfect grain and color match is not possible. By ordering from StairSupplies™, you acknowledge that you are receiving a uniquely crafted product and there may be some variation in the grain and color of your wood products.
