Best deck staining pros near Porcupine, SD

In most cases, sanding an old deck before staining it is necessary to achieve a decent finish. If your old deck has a relatively new stain finish on it and you're only doing touch-ups, you can generally skip the sanding part. However, if your goal is to make the deck look and function better, sanding first is a must. 

Yes, it is generally a very good idea to seal your deck after pressure washing. Power washing removes not only dirt and debris but also a thin layer of wood, leaving the surface exposed and more susceptible to weathering. Sealing is almost always needed after this process. After a general cleaning, sealing isn't automatically necessary if the existing sealant is still intact. You can test the surface by placing a few drops of water on it. If the water beads up, the sealant is working. If it soaks into the wood, it's time to apply a new sealant. If it has been a few years, it's wise to remove the old sealant, wash the deck, and reseal for maximum protection.

Avoid using cleaning products that are abrasive or contain bleach or acidic components on composite decking to avoid discoloration. Early-generation Trex decking isn’t designed to handle pressure washer cleaning—and if you use them on second-generation boards, always use a low setting to avoid the risk of damage that can risk voiding your warranty.

Yes, beginners can use a paint sprayer, but there is a learning curve. It's important to go slowly, read the instructions thoroughly, and spend some time learning the technique. Watching tutorial videos for your specific paint sprayer model can be very helpful. Before starting your main project, practice on a scrap surface to get used to the sprayer and avoid common issues like overspraying, which can cause drips, bubbles, and other imperfections. For safety, always wear a mask and gloves, and be careful not to touch the sprayer's tip when it's in use, particularly with high-powered airless sprayers.
