To protect your Trex decking from grease stains, you can consider applying a sealant specifically designed for composite materials. While Trex decking is engineered to resist stains, it can still absorb substances if not properly maintained.
First, clean the decking thoroughly to remove any existing grease or debris. You can use a composite deck cleaner or a mixture of soap and water, followed by a rinse with a hose. Allow the deck to dry completely before applying any sealant.
Next, choose a high-quality composite deck sealant. Look for products that are water-based and UV-resistant to ensure they won’t damage the Trex material. The cost for sealants typically ranges from $20 to $50 per gallon, and one gallon usually covers around 200-250 square feet, depending on the product and application method.
Apply the sealant according to the manufacturer's instructions, usually with a brush or roller, and allow it to dry fully before using the grill again.
For the best results, consider consulting with a local professional who has experience with composite decking. They can provide specific recommendations and ensure proper application. A good next step is to get 2–3 local quotes on Handyman.com for deck sealing services.
