Frequently Asked Questions (FAQ)
Q: What is the main difference between a sealer and a stain?
A: A sealer’s main job is to protect the wood from water and UV rays. A stain adds color to the wood and also offers some protection.
Q: How often do I need to reapply outdoor wood sealer?
A: This depends on the sealer and the weather. Usually, you’ll need to reapply every 1-3 years. Check the wood for signs of wear.
Q: Can I use any sealer on any type of outdoor wood?
A: It’s best to check the product label. Some sealers work better on certain types of wood, like cedar or pine.
