Installing duckboard: how should you saw?
Which tools do you need?
- Drilling machine
- Tape measure
- Spirit level
- Try square vibration plate (optional)
- Hand saw, radial arm saw or jigsaw
- Work gloves and hearing protectors.
What material do you need?
- Sand or cement
- Concrete tiles
- 6 stainless steel screws per shelf
- Bottom bars
- Anti-root fabric.
1. To begin
For the construction of the platform it is important that the surface is flat and solid. Remove any stones and branches and fill the surface with fill sand (if necessary). Use a vibrating plate to vibrate the sand. If you do not have a vibration plate, it is possible to press the ground with your feet or with a roller. Always let the terrace run a little towards the end of your garden, so that the rainwater runs away when it rains. Then use a spirit level to level the ground everywhere.
Laying tiles and placing anti-root cloth
After you have leveled the garden, place the pavement tiles at equal distance from each other. Measure with the spirit level if they also run slightly. Then place the anti-root cloth over the tiles and pull them tight. The anti-root cloth ensures that no weeds grow under your wooden deck. Instead of an anti-root cloth, it is also possible to use wood chips. These have the same effect as anti-root cloth. Now it's time to place the bottom beams (also called the frame) on which you later fix the decking boards.
2. Shortening with a radial arm saw
If the bottom beams and planks are not yet the right length, cut them to size with a crosscut saw. Choose for sawing wide deck boards for a crosscut with a pull function. With a trimming machine with pull function it is possible to pull the saw from front to back, giving you a larger cutting range. Mark the beams to the correct length and place the bar on the saw table. Lay the beam stably so that it does not move during cutting. Do not switch on the saw yet, but first lower it to check that you are exactly on the marked area. Hold the beam firmly, start the saw and slowly lower the saw through the beam. Repeat for all boards until they are all of the right size.
Shortening with a jigsaw or circular saw
If you do not have a radial arm saw, it is possible to use a jigsaw or circular saw. Mark the bars to the correct length with a square and place the saw on the line. Now slide the square to the bottom of the saw and draw a light line with your pencil. Place a guide bar along the last drawn line and secure it with a glue tong. Saw the plank through and make sure you move the saw tightly along the guide beam. This ensures the most straight result. With a circular saw it is also possible to use a guide rail. Mount an adapter on the circular saw and mark the workpiece. Clamp the guide, place the circular saw on the guide rail and cut the workpiece.
3. Lay the beams
After the root cloth is tight, place the support beams on top of the root cloth and on the tiles that are under the root cloth. The joists are beams that ensure strength and where you later fix the decking boards. They thus function as a framework for the decking boards. Keep an approximate distance of 40 centimeters between the bars. That creates a solid terrace. If you leave more space between the beams, your terrace will lose firmness and it may bend.
4. Install the deck boards
Now fix the decking on the support beams with stainless steel (platform) screws. It is important that you always use stainless steel screws. With normal screws, chances are that rust will develop over time. Countersink the screws by pre-drilling the decking planks with a (countersink) drill. Make sure that the diameter is about the same as the screw head. By screwing the screws into the board, the screws are nicely concealed. When installing the decking boards always keep space between the boards. This space allows the wood to expand and shrink.
5. The deck is finished!
Your deck terrace is finished and ready to be used! Work the wood with stain or oil. This gives your terrace a nice color and is immediately protected against weather influences.
