Key takeaways
- Transparent finishes show grain but protect less from sun.
- Semi-transparent stains balance color and grain.
- Solid stains cover color but can peel if prep is poor.
- Cleaning and drying are the most important prep steps.
Types of finishes
Clear sealers keep the natural look and repel water, but offer little UV protection. Semi-transparent stains add color and block more UV while showing grain. Solid stains look like paint and hide imperfections, but they can peel and are harder to refresh.
Match the finish to the wood
Cedar and hardwoods look great in clear or tinted finishes. Pressure-treated pine takes semi-transparent and solid stains well. New wood may need time to dry before finishing. Read the product's directions.
Prep is everything
Clean the deck, brighten the wood if needed, let it dry fully and sand or strip any failing finish. Finishing over dirt or moisture leads to peeling and blotches.
Timing and care
Apply on a dry, mild day and avoid direct hot sun. Follow the recommended coats and dry time. Plan to refresh every one to three years.
