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. 

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. 

Composite decking boards aren't your only options for building a deck. There are several other types of materials for decks, including wood and aluminum decking. Wood decking comes in many different wood species, offering natural beauty and classy timelessness to your yard. Aluminum is a lightweight, water-resistant, and low-maintenance material that is also non-slip.

While eco-friendly decking, also called composite decking, is a win for the environment because it consists of recycled materials, it has trade-offs. These sustainable options often come with steeper price tags, lack natural wood's warm look, and can become uncomfortably hot under full sun. Some composite materials can also become slick when wet, posing a potential hazard.
