Texas sun is hard on outdoor wood. In San Antonio, long summers, strong UV rays and sudden storms break down a deck's finish faster than most homeowners expect. UV light fades the color, dries out the boards and lets water soak in, which leads to graying, cracking and splintering.
Wood versus composite matters here. Real wood such as cedar, pine or redwood needs a protective stain or sealer on a regular schedule. Composite decking does not need staining, though it still benefits from cleaning, and some older composite boards can fade in direct sun.
Signs your deck needs restaining are easy to spot. Water no longer beads on the surface and instead soaks in. The boards look gray, faded or blotchy. You see cracks, rough patches or raised splinters in high-traffic areas like stairs and walkways, where the stain is peeling or worn away.
A good rule of thumb for San Antonio is to restain every 2-3 years. Decks in full afternoon sun, or with heavy foot traffic, may need attention closer to every two years, while shaded decks can often stretch toward three. Do the water test each spring to decide.
When you restain, clean the deck first, let the wood dry fully, and apply a quality UV-resistant stain in even coats. Skipping prep is the most common reason a new stain fails early.
