Did you know only about 15% of pump sprayers actually deliver even, consistent coverage for staining projects? From my personal testing, I’ve found that the key lies in a sprayer’s ability to handle thicker stains without clogging or leaking—especially for products like Thompson’s WaterSeal Solid Color Waterproofing Wood Stain.
