How to Fix and Prevent Cracks in Composite Decking?

Have you ever walked out onto your beautiful composite deck, only to notice unsightly cracks in the composite deck planks? It’s a common issue that many homeowners face. But fear not, because understanding the causes of composite decking cracks and finding the right solutions for fixing cracks in composite decks can ensure your outdoor space remains both stunning and sturdy.

What Causes Composite Decking to Crack?

Cracks in composite timber decking often stem from a few key issues. One primary cause is unilateral expansion due to inadequate ventilation at the moisture-proof layer’s connection. During installation, if this layer isn’t securely sealed with waterproof tape, moisture can sneak in. This imbalance in moisture content causes one side of the composite deck plank to expand more than the other, leading to frustrating triangular seams.

Another factor is improper humidity control. If a room with composite decking is left vacant for extended periods without humidity adjustments, the planks can shrink, leading to cracking or even arching. Lastly, improper installation can also contribute to the problem. Uneven force during installation might result in gaps, but the good news is, that these can often be rectified.

Effective Measures to Fix Cracks in Composite Decking

Dealing with cracks in composite decking isn’t just about aesthetics; it’s also about maintaining the integrity of your composite deck. If the room is empty for a while, a simple trick like placing a basin of water inside can help balance the indoor humidity, reducing the likelihood of gaps forming.

For smaller gaps, a blend of bakelite powder offers an effective solution. Mix it, apply it to the cracks, and let it set overnight. For a more eco-friendly approach, water-based transparent putty mixed with sawdust works wonders, perfectly blending with the composite deck’s natural color and texture.

For larger cracks, glass glue can be a temporary fix, but it’s not just about filling the gaps. The real magic happens in the maintenance. Regular cleaning with a semi-dry rag, especially during heating periods, helps manage the humidity levels, reducing gap size. Come summer, a bit of solid wax can help seal the deal, ensuring your composite decking remains as good as new.

Composite Decking Maintenance: How to Prevent Cracks

Composite decking care involves more than just fixing cracks; it’s about preventing them. Regular cleaning, avoiding harsh chemicals, and maintaining an even humidity level are crucial. Always follow the manufacturer’s guidelines for cleaning and maintenance to keep your composite deck looking pristine.

Tip 1: Regular Cleaning

Keep your deck clean by sweeping it regularly to remove dirt and debris. For a deeper clean, use a mild soap and water solution or a composite deck cleaner recommended by Oakio. Avoid harsh chemicals that can damage the deck’s surface.

Tip 2: Managing Humidity

If your deck is in an area with fluctuating humidity, take steps to manage the moisture levels. Using dehumidifiers or humidifiers in adjacent indoor spaces can help maintain a consistent environment, reducing the risk of material expansion and contraction.

Tip 3: Immediate Repairs

Address minor damages or cracks immediately. Small issues can become bigger problems if ignored. For Oakio composite decking, use recommended repair solutions to ensure compatibility with the material.

Tip 4: Avoiding Harsh Chemicals

When cleaning or making repairs, avoid using harsh chemicals or abrasive cleaners. These can damage the surface of your composite deck. Always follow Oakio’s guidelines for cleaning and maintenance.

Tip 5: Proper Installation

Ensure your deck is properly installed with adequate ventilation and spacing. This prevents moisture accumulation and promotes even expansion and contraction, reducing the risk of cracking.

Tip 6: Seasonal Checks

Inspect your deck at the start of each season. Look for any signs of wear and tear, such as loose boards or visible cracks, and address them promptly.

Tip 7: Protect from Heavy Objects

Be mindful of heavy objects on your composite deck. Excessive weight can cause strain and potentially lead to cracking. Use furniture pads to distribute weight evenly.

Tip 8: Sunlight Management

If your composite deck is exposed to direct sunlight for long periods, consider using outdoor rugs or shades to protect against UV damage and excessive heat, which can contribute to fading and warping.

Tip 9: Professional Consultation

If you’re unsure about any aspect of your composite decking maintenance, don’t hesitate to consult with a professional. They can provide specific advice tailored to your deck’s condition and environment.

Taking care of your composite deck, especially quality products like Oakio composite decking products, is not just about fixing cracks; it’s about proactive maintenance.
