Clear Finish & Stain Information

StairSupplies™ offers several premium stain and finish options for our products, depending on the product’s use. For Winder Stair Treads, 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 Winding Treads.

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 applies this specialty product onto each stair tread using a spray applicator for even, flawless coverage to protect your treads 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.

Product Q&A

I want to replace a 38.6-in. landing with a 3-pc. winder. The steps coming down to the landing are 28-in. but the one step below the winder can be wider. I am assuming that the 42-in. winder would work best, as I think we need to allow for a 1.3 overhand on each of the three winder treads. Am I correct?

Could you please tell me what size winder should I order?

Hi Carol,
We always recommend that you oversize the winders in order to cut them down on the job site. If you’re replacing a landing tread that is 38.6″ square, we’d definitely recommend you purchase the 42″ winder, as that will give you plenty of material to work with.
Please let us know if you have additional questions.

I’m building my stairwell and putting in a 3-piece winder. my stairwell is roughly 36 inch wide, but the way I’ve designed the winder the tread will be 5-1/2 inch on the inside corner with the middle tread having a notch in it. So, I wonder if I should consider 48 inch treads so I’ll have sufficient stock to work with. What do you think?

We can definitely provide you with exactly what you need, but in order to make sure we get all the dimensions and details correct, I would recommend calling one of our design experts at (866) 226 6536 to make sure we get it right.
