Wooden deck

Have fun with our wooden deck! It could provide the perfect stage for your indoor plants. Or you could use it to liven up your patio. Or even add a raised area to one of your rooms. In fact, there's no limit to the number of ideas you can come up with!

The substructure of our deck consists of two supports that bear the frame and the deck planks. The frame overhangs the substructure, so that the deck planks, which are screwed to the supports, are enclosed and aligned within the frame. If you want to build a larger deck, bear in mind that you will need an additional support for every 50 to 60 cm of deck.

The following assembly instructions apply to 27-mm-thick spruce glued laminated timber. You must adapt the list of materials accordingly if you opt for other materials or thicknesses.

Note that spruce timber, whether painted or varnished, is less weather-resistant than other types of timber. If you want to be certain of weather resistance, choose teak or acacia wood.

If possible, ask your DIY store or carpenter to cut the required boards to size.

Instructions

Assemble the supports

Enlarge

1

Assemble the supports

Start by fastening the supports with screws. Each of the supports is made from a square timber combined with a base plank. The two outer square timbers are upright and aligned on the outside edge, while the centre square timber is positioned in the middle of the base planks. Using the cordless screwdriver and screws (4 x 60 mm), mount the square timbers from below through the base planks.

Tip for screwing together two pieces of wood

In the piece where you want to insert the screws first, always predrill a hole that is 0.5 to 1 mm larger than the screw diameter; the hole should be countersunk for the screw head. In the piece that you are going to drill second, predrill a hole that is always 1 mm smaller than the screw diameter.

Mount the frame and supports

Lay the frame surrounds with the visible surfaces facing down in the way you want to assemble them. The short frame surrounds are enclosed within the long frame surrounds. Using the cordless screwdriver and screws (4 x 60 mm), join the surrounds to form a single frame. Refer to our tip on screwing together two pieces of wood in the previous section.

Now mount the supports so they are parallel with the long frame surrounds and flush below with the square timbers in the frame, as shown in our illustration. The base planks are facing upwards. Place the plank with the centrally-fastened square timber in the middle of the frame and the planks with the left and right-fastened square timbers to the left and right respectively.

Now use the cordless screwdriver and screws (4 x 60 mm) to fasten the supports in place. Refer again to our tip on screwing together two pieces of wood.

Mount the deck planks

Now predrill the deck planks in preparation for fastening them with screws. Position two holes in the centre above the square timbers (see illustration) and countersink the holes. Place the deck planks inside the frame on top of the supports using 7-mm spacer blocks and mount them in place with the cordless screwdriver and screws (4 x 60 mm).

Sand wood surfaces

Sand wood surfaces

Take time to prepare the wood surfaces so they are in the best possible working condition before starting assembly.

First chamfer all edges with sanding paper with a grit of 120 at a 45° angle until a small bevel is created. Use your sander to sand all visible surfaces in the direction of the wood grain, first with coarse sanding paper (grit of 120, 180) and then with fine sanding paper (grit of up to 240).

Damp sponge the surfaces afterwards to wipe off the dust. Some loose wood fibres may protrude while the wood is drying. You can remove these with sanding paper with a grit of 180. The wood is now ready for surface treatment. Little tip: Make sure that the sanding paper is sharp enough to remove the wood fibres properly, not just flatten them.

Varnish the surfaces

Varnish the surfaces

First read the manufacturer's safety and handling instructions thoroughly. Make sure the room you are working in is well ventilated and not used for smoking, eating or drinking.

Generously apply the varnish with a fine spray system and remove any excess varnish with a cloth. Observe the drying times specified by the manufacturer.

Before applying a second coat, you must sand the surface a second time with sanding paper with a grit of 240. Once again, you must always sand in the direction of the wood grain. Repeat the application as described in the section above.
