How do I seal Trex decking to keep it from absorbing grease from the grill that is spilled on the deck?

To protect your Trex decking from grease stains, sealing it is a good approach. While Trex decking is designed to resist stains and fading, it can still absorb certain substances. Here are the steps you can take: 1. **Clean the Decking**: Start by thoroughly cleaning your Trex decking. Use a mild detergent and a soft-bristle brush to scrub the surface. Rinse well with water and allow it to dry completely. 2. **Choose a Sealant**: Look for a sealant specifically designed for composite decking. These products are usually water-based and can help repel stains. Brands like Defy or Behr often have suitable options. Prices for sealants typically range from $20 to $50 per gallon, depending on the brand and features. 3. **Apply the Sealant**: Follow the manufacturer's instructions for application. Generally, you will want to use a paint roller or a sprayer for even coverage. Make sure to apply it on a dry, sunny day to ensure proper drying. 4. **Reapply as Needed**: Depending on the product, you may need to reapply the sealant every couple of years to maintain its effectiveness. For the best results, consider hiring a professional who has experience with composite decking. You can get 2–3 local quotes on Handyman.com to find someone qualified. — Assisted answer
