How to Lay Deck Boards: The steps

To lay deck boards, do make use of the following steps:

  • Level the ground before laying the wood
  • The choice of wood is crucial
  • Take care that the corners are well
  • Details that must be taken care of
  • Level the wooden slates perfectly
  • Placing the wood
  • Attention to the deck finishes
  • Prevent weeds
  • Protect the wood

Level the ground before laying the wood

If you desire your deck to be a stable construction, the first thing you have to do is level the ground you will put it. You can dress a cement base on the floor to cover the deck for more excellent stability. After leveling the ground, the next thing is to place the wooden beams that will serve as the base for the deck’s wooden boards.

How to Lay Deck Boards

The choice of wood is crucial

You must choose the type of wood you are going to use well. Remember that although wood can be varnished to make it more durable, it is also true that the natural durability of this material depends a lot on the species of tree from which the wood is obtained.

Once you have chosen the wood type you will use, place the wood on the beams to serve as a base and support. The deck boards are always placed perpendicular to the base beams.

Take care that the corners are well

Before installing the boards, be sure to cut them to fit the size and shape of your deck perfectly. In this way, you will make each corner look perfect. For cutting them get Portable Gypsum Board Cutting Device.

Details that must be taken care of

Leave an invisible space between the boards, about a millimeter, to ensure ventilation at the bottom of the deck. This will prevent the fungus from growing under the wood.

Level the wooden slates perfectly

When you place the wooden slats on the bases, they should be fixed with screws or with the same cement or special adhesives to the concrete. You must be sure that both the bases and the wooden slats are well leveled in both directions. In this way, your floor will be level throughout its length.

Placing the wood

The floorboards must be worked with a tongue and groove to be fixed between them without leaving spaces. These boards should be placed perpendicular to the guides that you set on the base cement. You do this with flat head stainless steel screws, placing a double screw for each stave or board, and to make it more finished, the screw is lowered a few millimeters below the level of the board you are placing.

Next, this space should be filled with Sawdust; the same color as the wood and a suitable glue, so that the screw heads are not visible. If the deck integrates trees or other structures typical of the garden, some boards should be cut to follow the proper shape.

Attention to the deck finishes

The deck already has its wood in place, and you need to decide what to do. You can leave the wood with its initial treatment and only cover it with a sealing varnish, following the manufacturer’s instructions or give it a matte or glossy varnish according to your preference.

The sides that are below the floor of the house should be treated with some cement. The joint between both floors should also be filled with some specially dosed cement to seal it and prevent problems later with some leakage.

Prevent weeds

Apply herbicide so that weeds do not grow. Spreading a layer of gravel and avoiding weeds will improve the drainage of the land.

Protect the wood

Apply an impregnate or wood protector to the beams installed and the boards that will form the deck. It can be a colorless or tinted protector.

How to Lay Deck Boards: Frequently Asked Questions

What is the correct way to lay decking boards?

As earlier highlighted, the steps in laying decking boards are not complicated. This includes:

  • Level the ground before laying the wood
  • Make the proper choice of wood 
  • Take care that the corners are well
  • Take care of other details
  • Level the wooden slates perfectly
  • Place the wood correctly
  • Pay attention to the deck finishes
  • Prevent weeds
  • Protect the wood

How do you stagger deck boards?

Wooden decks are typical exterior decoration for houses, allowing families to have more space to enjoy outdoor activities. There are wooden boards for walking on the deck, but if these boards are shorter than the deck’s width, more than one board must be used in each row. The pattern of staggered joints is a way to help spread any necessary boards throughout the pattern.

A common way to stagger the decks is to start with a whole plank from the first row and then cut a third of the first plank in the second row from the end. On the next row, cut another third, and then repeat when returning to the whole board. However, the deeper the deck, the more pronounced the repeating pattern would be, as your chosen pattern will begin to repeat itself regularly at this point. If you want more randomness, you can customize the deck’s stagger to create the desired look.

Can you lay decking on soil?

There are two options for laying decks. You can either build it directly on the ground or place it in a square shape and then build it on top of the floating platform’s riser. If you put it directly on the soil, it may easily absorb moisture and require additional maintenance.

What do you put under decking?

Compacted gravel put under decking can adequately drain and keep water away from the wood chips. This helps prevent decay and extend the life of the deck. When using gravel under the deck, it prevents water from accumulating in the ground, thereby reducing erosion-related problems that can damage your deck.

If the area under your deck or stairs will get moisture, it is also best to use an inorganic covering such as mulch or river rocks.

Is it better to nail or screw deck boards?

For deck construction, it is best to use screws. Screws are an excellent choice for laying wooden floors. They can hold items better, wash out better, and have better fastener/tensile strength to prevent the boards from popping out over time.

Last Words

In conclusion, without a doubt, deck boards are very functional structures which are quite decorative and healthy. These also stand as elements that can change your outdoor space’s appearance and give you great satisfaction. Furthermore, when working on how to lay deck boards, the steps highlighted above would be indispensable.
