Writer's picture: JCSJCS

Applying end seal to decking is a crucial step in preserving and protecting the wood. Here's a detailed guide on how to apply a seal to your hardwood decking:


1. Choose the Right End Seal:

- Select an end seal product specifically designed for the type of decking material you have. Different wood species may require different formulations.


2. Timing Matters:

- Apply the end seal as soon as possible after cutting the decking boards. This helps prevent moisture from penetrating the freshly cut ends, reducing the risk of splitting or checking.


3. Clean the Ends:

- Ensure the ends of the decking boards are clean and free of any dust or debris. Use a brush or compressed air to remove loose particles.


4. Shake or Stir the End Seal:

- If the end seal comes in liquid form, shake or stir it well before application to ensure an even distribution of protective agents.


5. Application Method:

- Use a brush, sponge, or roller to apply the end seal. Ensure even coverage on all exposed end grain surfaces.


6. Concentrate on the Ends:

- Focus the application on the cut ends of the decking boards. Apply the end seal generously to create a protective barrier against moisture.


7. Follow Manufacturer's Recommendations:

- Adhere to the manufacturer's guidelines regarding drying times and reapplication intervals. Some products may require multiple coats for optimal protection.


8. Avoid Overlap:

- Be mindful not to overlap the end seal onto the decking surface. Wipe off any accidental spills promptly to prevent an uneven appearance.


9. Allow Sufficient Drying Time:

- Let the end seal dry completely before exposing the decking to foot traffic or adverse weather conditions. Follow the recommended drying times provided by the product manufacturer.


10. Regular Maintenance:

- Periodically inspect the decking ends and reapply the end seal as needed, especially after any additional cutting or alterations.


11. Dispose of Materials Properly:

- Dispose of used brushes, applicators, and any excess end seal in accordance with local environmental regulations.

​

By following these steps, you'll help protect your decking investment, ensuring longevity and maintaining the aesthetic appeal of your outdoor space. Always refer to the specific recommendations provided by the end seal product manufacturer for the best results.

Want to go Eco-Friendly?


Opting for eco-friendly sealants for hardwood decking is a great way to minimize environmental impact while protecting your decking boards. Here are some options:

  1. Plant-Based Oil Finishes: Plant-based oils, such as linseed oil, tung oil, or soybean oil, are eco-friendly alternatives to traditional sealants. These oils penetrate the wood fibers, nourishing and protecting the wood while enhancing its natural beauty. Look for products labeled as eco-friendly or sustainable.

  2. Water-Based Sealants: Water-based sealants are typically lower in volatile organic compounds (VOCs) compared to solvent-based sealants, making them a more environmentally friendly option. These sealants provide protection against moisture and UV damage while emitting fewer harmful chemicals into the environment.

  3. Eco-Friendly Stains: Some stains are formulated using natural, non-toxic ingredients that are safer for the environment. Look for stains that are labeled as low-VOC or VOC-free and made from renewable resources. These stains provide color and protection to hardwood decking while minimizing environmental impact.

  4. Natural Waxes: Natural waxes, such as beeswax or carnauba wax, can be used as eco-friendly sealants for hardwood decking. These waxes create a protective barrier on the surface of the wood, helping to repel water and prevent moisture damage without emitting harmful chemicals.

  5. Bio-Based Sealants: Bio-based sealants are made from renewable resources, such as plant oils or natural resins, and are designed to provide long-lasting protection for hardwood decking while minimizing environmental impact. Look for products certified as biodegradable or made from sustainable sources.

  6. DIY Options: For a truly eco-friendly sealant option, consider making your own using natural ingredients such as beeswax, linseed oil, or citrus solvents. There are many DIY recipes available online that allow you to create custom sealants tailored to your specific needs and preferences.

Before applying any sealant to your hardwood decking, be sure to carefully read the product labels and instructions to ensure it meets your eco-friendly criteria and is compatible with your decking material. Additionally, consider factors such as durability, UV protection, and maintenance requirements when choosing the best eco-friendly sealant for your decking project.
