It certainly can. As with paint, a quality stain will more than pay for itself by its longevity. After all, the labor component of a job — whether you do it yourself or pay someone else — is a much more important “cost” than the materials. A quality stain can last as much as twice as long as a cheap product — that means many more years without a re-do. Also, be sure to compare the spread rates between the higher and lower priced products. You may discover that the “high priced” product has a greater covering capacity than the cheap one and, therefore, isn’t really so much more expensive on a square foot basis.
