I give the Wagner 590 Power Sprayer an 8.5 out of 10. Here’s a review and walk through on how to use. Overall, I really enjoyed using it. I was able to save a lot of time and achieve a good result. I have since used it to stain cabinets and it did a great job there as well. My only gripe is that it takes a long time to clean; I assume most sprayers do. Also, the power cord is too short. I recommend this product. Check out my YouTube channel for more DIY videos. I have every step of fully renovating this condo. Enjoy!
