Buying Guide
Choosing the right clear sealer for your cedar fence can feel overwhelming, but here are a few key things to keep in mind:
- Climate: Consider your local weather conditions. If you live in a rainy area, prioritize water resistance. If you’re in a sunny area, look for UV protection.
- Type of Wood: Cedar is naturally resistant to decay, but it still needs protection. Make sure the sealer is specifically designed for use on wood.
- Ease of Application: Some sealers are easier to apply than others. If you’re a DIYer, look for a product that’s easy to use with a brush, roller, or sprayer.
- Desired Finish: Clear sealers come in different finishes, such as matte, satin, and glossy. Choose a finish that complements the natural beauty of your cedar fence.
- Longevity: Consider how long the sealer is expected to last before needing to be reapplied. Longer-lasting sealers may cost more upfront but can save you time and money in the long run.
