Get matched with top deck staining pros in Harold, KY

Yes, you can stain your wood deck over old stain, but proper preparation is the key to successful results. Begin by thoroughly cleaning the deck to remove dirt, debris, and loose or flaking old stain. Sanding or stripping may be necessary to smooth the surface and ensure proper adhesion of the new stain. Test a small area to ensure compatibility between the old and new stain. Also, choose a stain compatible with the existing stain type and color. By following these steps meticulously, you can achieve a refreshed appearance while preserving the integrity of your deck.

Ultimately, overapplication of stain can compromise the deck's appearance, durability, and longevity. It may result in an uneven finish, with excess stain pooling, dripping, or drying into thick patches. It can also obscure the wood's natural grain and texture, detracting from the desired aesthetic. Moreover, excessive staining may not fully penetrate the wood, leading to poor adhesion and premature wear. Additionally, thick layers of stain are prone to peeling, cracking, and blistering as they struggle to bond with the surface. 

Acrylic paint is one of the best types of paint to use on your home's exterior. It's a durable paint that is also heat- and cold-resistant. While oil-based paint is also durable, it's prone to fading,  making it not as good of an option if you live someplace with extremely high heat. In colder regions, oil-based and alkyd paints become more viscous, which makes it harder to apply the paint.

You can apply stain over peeling stain, but it’s not a good idea. Your old stain will get in the way of your new stain bonding to the wood, so you’re likely going to see the same issue again shortly after application. Your best option is to sand off the old stain and clean the surface thoroughly before applying new stain.
