Advanced PVC vs. Capped Composite for Pool Areas
TimberTech's product lines are divided into two main technologies: Azek, which is full PVC, and Pro and Edge, which are capped composites. The choice between these two is particularly important for pool surrounds due to their differing reactions to moisture.
TimberTech Azek advanced PVC decking contains zero wood fiber, making it impervious to moisture absorption. This characteristic is a significant advantage for areas consistently exposed to water, such as pool decks, hot tub surrounds, and docks. PVC boards are engineered for environments where water is a constant factor.
TimberTech Pro and Edge decking are capped composite boards. These feature a protective polymer cap on multiple sides, designed to resist moisture, fading, and staining. While they offer good performance in outdoor settings, the full PVC Azek line is specifically highlighted for its zero moisture absorption properties, making it a primary consideration for direct pool contact.
All three lines are designed with realistic grain patterns, aiming to replicate the appearance of hardwood. However, their core material differences dictate their optimal application areas, especially concerning prolonged water exposure.
For a pool surround, the primary decision often hinges on the level of moisture immunity required. Azek's full polymer composition makes it a strong candidate where water saturation is expected regularly.
Understanding Moisture Resistance and Performance
The constant presence of water from splashes, wet feet, and pool maintenance makes moisture resistance a critical factor for pool decking. This makes it suitable for ground-contact applications and areas with high humidity or direct water exposure.
Capped composite decking, such as TimberTech Pro and Edge, features a protective cap that helps resist moisture, but it is not entirely impervious to water in the same way full PVC is. The core of composite boards contains wood fibers, which can be susceptible to moisture if the cap is compromised or if water penetrates uncapped edges.
For pool surrounds, selecting a material that can withstand repeated wetting and drying cycles without degrading is essential. The zero absorption property of Azek PVC helps maintain board stability and appearance over time in such demanding conditions. This can contribute to a consistent surface around the pool area.
Cleaning and Maintenance for Pool Decks
Maintaining a clean and safe pool surround is important. TimberTech decking is designed for easier cleaning compared to traditional wood, which can be prone to mold and mildew in damp environments. Both PVC and capped composite boards are generally resistant to staining and mold growth.
For routine cleaning of pool decking, a mild soap and water solution is typically sufficient. Specific cleaning products compatible with TimberTech decking are recommended to avoid damaging the surface. It is important to remove any pool chemicals or spills promptly to prevent potential surface etching or discoloration.
The non-porous nature of Azek PVC can simplify cleaning, as it does not absorb liquids. This can be an advantage when dealing with pool water, suntan lotions, or other common poolside substances. Always refer to the manufacturer's specific cleaning guidelines for your chosen TimberTech product line.
Designing Edges and Fascia for a Pool Surround
The finished appearance of a pool deck is greatly influenced by how the edges are handled. TimberTech offers matching fascia and trim boards across its lines, allowing for a cohesive look. Fascia boards are used to conceal the substructure and the exposed edges of the deck boards, providing a clean, finished perimeter around the pool.
When planning a pool surround, consider whether you want the decking to butt directly against the pool coping or have a slight reveal. Proper spacing and ventilation are important regardless of the chosen edge detail.
For square-edged boards, the Cortex plug system can be used for face fastening, providing a color-matched finish. Grooved boards are compatible with hidden clip fastening systems, which create a smooth, fastener-free surface. Both options are available across TimberTech lines, ensuring flexibility in design choices while maintaining a uniform appearance with the main deck boards. This consistency in fastening and fascia programs simplifies material coordination.
Project Example: Planning a 12x20 Foot Pool Surround with Azek PVC
Consider a hypothetical pool surround project for a rectangular pool, where the decking area measures 12 feet by 20 feet. The homeowner prioritizes maximum moisture resistance and a consistent surface, leading to the selection of TimberTech Azek PVC decking in a square profile for face fastening.
The decking will be laid parallel to the 20-foot dimension of the pool. TimberTech Azek boards are available in 12, 16, and 20-foot lengths. To minimize seams and maximize efficiency for the 20-foot length, 20-foot boards are the most practical choice. For the 12-foot width, boards will need to be cut.
For the 12-foot width, you would need multiple runs of boards. Since boards are purchased in full lengths, 26 full 20-foot boards would be a starting estimate. Additionally, fascia boards would be needed for the perimeter. For a 12x20 foot area, you would need approximately two 20-foot fascia boards and two 12-foot fascia boards, which would be cut from 12 or 16-foot stock. Always factor in waste for cuts and potential errors when ordering.
For a pool surround, ensuring adequate support and drainage beneath the deck is crucial. A well-designed substructure that allows for water runoff and air circulation will contribute to the longevity of the deck.
This example illustrates the importance of selecting appropriate board lengths to minimize waste and considering the number of boards required for both the main deck surface and the perimeter finishing elements.
Before you order
- Assess the expected level of water exposure: Will the deck be constantly wet or only occasionally splashed?
- Consider material type: Is Azek advanced PVC (zero moisture absorption) or capped composite (moisture resistant cap) more suitable for your specific pool environment?
- Review cleaning and maintenance requirements: Are you prepared for routine cleaning to prevent chemical residue or staining?
- Plan edge details: How will the decking meet the pool coping? Will you use matching fascia boards?
- Verify joist spacing and substructure: Is your existing or planned substructure compatible with TimberTech decking requirements for strength and drainage?
- Measure accurately: Account for board width, length availability, and cutting waste for your project dimensions.
- Consult product specifications: Confirm specific installation guidelines and recommendations for your chosen TimberTech line around water.
Confirm installation details, approved uses and warranty terms in the current instructions for the exact product and profile. Your installer should verify the substrate, structure and applicable project requirements.
Questions to help you decide
Which TimberTech line is best for a pool deck?
TimberTech Azek advanced PVC decking is generally considered the best option for pool decks due to its full polymer composition, which makes it impervious to moisture absorption. This property helps it perform reliably in consistently wet environments.
Can TimberTech decking be installed directly on the ground around a pool?
However, proper substructure and ventilation are still critical to ensure stability and drainage. Consult specific installation guidelines for your chosen product and local building codes.
How do I clean pool chemicals or splashes from TimberTech decking?
For general cleaning, a mild soap and water solution is often effective. Any pool chemicals or spills should be cleaned promptly to prevent potential surface damage. Always refer to TimberTech's specific cleaning and care instructions for your particular decking line to ensure compatibility and avoid discoloration or etching.
