How to Lay Decking Boards

Your Guide to Lay Deck Boards the Right Way

By John Johnston

Laying your deck boards the proper way is essential for a stunning, safe outdoor deck.

Start by choosing the right materials. You can pick wood or composite. Each has unique benefits.

Measure and cut accurately. Keep an eye on the ridge ‘groove’. It improves traction and moisture control. Your decking’s foundation needs to be spot-on, with even spacing and level joists.

As someone who professionally builds house decking, the best tools for the job are: a power drill, circular saw, level, and decking spacer for uniform gaps.

And don’t forget, correct installation makes it less slippery and reduces slipping hazards.

It also keeps your deck durable and nice to look at. Discover more insights below to perfect your deck installation project.

What is a Decking Board

Understanding a decking board is key. It’s the foundational part of outdoor decks. It offers both support and style.

When you’re ready to lay garden decking, it’s vital to choose the right material.

Deck boards come in two primary types: wood and composite decking. Wood offers a classic, natural look but needs more maintenance. Composite decking is durable and needs less upkeep.

You can use PVC for decking but is the least recommended

Each board must be precisely laid onto a sturdy frame to guarantee your deck’s longevity and safety.

Installing involves measuring, cutting, and securing the boards. You must ensure they’re evenly spaced for a cohesive look.

Mastering the art of laying deck boards isn’t just about following steps. It’s about knowing the materials, the frame, and the techniques to bring your outdoor vision to life.

What is the Purpose of Deck Board Ridge “Groove”

One might wonder why some deck boards require a ridge side or ’groove’ along their edges.

It’s not just for looks, but serves an important purpose in the deck’s building and life. These grooves aid in reducing slip hazards, making your deck safer to walk on, especially when wet.

They’re designed to improve traction. They offer an anti-slip surface. This is key for outdoor areas exposed to rain and moisture.

Additionally, the ridge side allows for better airflow between the boards, which is necessary for preventing moisture buildup.

This airflow helps to keep the deck dry, reducing the risk of rot and extending the life of your deck.

By incorporating these ridges, you’re not only enhancing safety but also ensuring your deck remains durable and aesthetically pleasing for years to come.

Correct Way to Lay Decking Boards: Composite

Laying composite decking boards starts with proper preparation, guaranteeing you have all the necessary tools and materials at hand for a smooth installation process.

First, you’ll need to measure and mark your deck area accurately. Then, prepare your joists to make certain they’re level and spaced correctly for the composite boards you’re using.

When laying the boards, pay attention to the angle at which they meet the joists, as this can impact the stability and appearance of your deck.

  • Measure the deck area with precision.

  • Level and space joists correctly.

  • Choose the right angle to lay boards.

  • Fasten boards securely to joists.

  • Check alignment and spacing as you go.

This methodical approach ensures your composite deck isn’t only aesthetically pleasing but also structurally sound.

Best Tools to Help Lay Decking Boards?

Having the right tools can make your decking project not only easier but also more efficient and precise.

To install decking, whether it’s wood decking or timber decking, you’ll need a solid lineup of tools.

Power DrillUsed for drilling pilot holes and driving screws to securely fix the decking boards.
Circular SawEssential for cutting planks to the required length, ensuring a neat and precise fit.
LevelHelps in ensuring that the decking boards are perfectly horizontal and evenly laid.
Decking Spacer ToolAids in maintaining consistent gaps between planks, which is crucial to avoid warping and damage.
Tape MeasureNecessary for measuring the decking area and the planks for accurate cutting and placement.
PencilUsed for marking measurements on the planks to guide cutting and aligning.

How to Prevent Slipping on Deck Boards?

How can you guarantee your deck remains a safe, slip-free zone throughout the year?

You must ensure your exterior space is beautiful. It must also be functional and safe. Doing this means tackling the slippery challenge head-on. Here are five practical steps:

  • Choose anti-slip decking boards: Opt for materials designed with a non-slip surface or texture for maximum grip, even when wet.

  • Apply anti-slip tape: Durable, self-adhesive tapes provide an immediate grip solution, especially on existing decking areas.

  • Regular cleaning: Prevent mould and mildew buildup, which can make surfaces slippery, by maintaining a regular cleaning schedule.

  • Ensure proper water flow: Design your deck to allow water to flow away efficiently, avoiding standing water.

  • Use anti-slip coatings: Exterior-grade, anti-slip coatings can be applied to deck boards, offering a durable solution to enhance traction.

Why do People Install Decking Wrong?

While preventing slips on your deck is important, it’s also essential to address why decks are often installed incorrectly, leading to potential safety and durability issues.

Many jump into the project without knowing the right way to install deck boards. They ignore expert advice.

They might place boards too close together, not allowing for expansion, which can cause the wood to warp or rot.

Others might choose the wrong materials for their climate, or fail to seal and treat the wood properly. This oversight can drastically shorten the deck’s lifespan.

You need to learn the right installation techniques.

You also need to understand material properties. And, you should follow professional advice.

These are key steps to avoid these common pitfalls and to keep your deck safe, functional, and beautiful for years to come.


So, there you have it! The right way to lay decking boards isn’t just about looks.

It’s about making a safe, durable outdoor haven that lasts. You need to choose the right materials. You also need to use the perfect tools for the job.

Each step in your decking project adds up to make a big difference. And remember, the devil is in the details!

Laying each board correctly is crucial. You must keep the gaps for airflow and add anti-slip measures.

These steps are part of the journey to a flawless finish.

Frequently Asked Questions

Can you lay decking on soil?

Laying decking directly on soil isn’t ideal, as soil movement can lead to an unstable and uneven deck over time.

Instead, consider a proper foundation: clear vegetation, lay a weed barrier, and establish a gravel base or concrete supports.

Check out this blog post how to lay decking on grass. This will ensure your deck is stable and durable, avoiding potential shifts or damage.

Wood vs composite?

Choosing between wood and composite decking depends on your preferences and needs.

Wood decking offers a natural look and is cost-effective initially, but it requires regular maintenance like staining and sealing.

Composite decking, made from wood fibers and recycled plastics, is more durable and requires less upkeep, though it tends to be more expensive upfront.

Consider what’s more important for you: the natural aesthetic and feel of wood or the longevity and low maintenance of composite materials.

Do the fasteners affect the longevity and safety of deck boards?

The type of fasteners you choose plays a crucial role in both the longevity and safety of your deck.

Using the wrong fasteners can weaken the structure or cause the wood to split. Stainless steel screws are generally recommended for their durability and rust resistance.

Hidden fasteners provide a sleek look but require careful installation. Selecting the right fasteners depends on your deck material and design preferences.

What maintenance is required to keep deck boards in top condition?

Regular maintenance is key to extending the life and beauty of your deck.

For wood decks, annual sealing is necessary to prevent water damage. Composite decks benefit from routine sweeping and washing to remove dirt and debris.

Each type of decking has specific care requirements, so it’s important to use products suited to the material to avoid damage.

Are there specific building codes for decking

Yes, when building a deck, you must adhere to various local building codes and regulations.

These rules can vary by location but generally include specifications for railings, board spacing, and material types.

Ensuring compliance with these regulations can prevent legal issues and safety hazards. Always check local guidelines before starting your deck project to ensure it is up to code.
