After you have constructed your various kitchen units, the next step is to join them to each other, push them back against the wall and anchor them in place.
The trick is to move the units as close to ‘in position’ as possible. Then make sure all the units are exactly the same height, adjusting the adjustable legs until the backs and fronts are flush at the top.
Use quick clamps to clamp the units together. Make sure there are no spaces between two separate units. Then find four to five spots, not too obvious to the naked eye, where you will screw the units together. An unobtrusive way is to do three in a row as deep as you can inside the unit. Make your pilot holes, one as low as possible, one as high as you can and one in the middle. Then drill two pilot holes in the front. Do one low again, about 50mm from the edge, and one just below the top horizontal cleat.
Now secure the unit with 30mm screws considering your work material is a total of 32mm thick. It is now safe to remove the clamps, and move the entire row of units into place against the wall.
Lay a long level across the units and make sure everything is level by setting the final height on your adjustable legs. Here it is important to make sure all the cupboards actually touch the level. You don’t want just the two ends to be level and the rest sags in the middle as this will be visible once you attach your Formica LifeSeal Worktop.
When fixing cabinets to a wall it is important that your fixing must be able to carry your cupboard, especially the wall units. You could put anchors through 3mm hardboard, but for durability, it is recommended that you only put anchors through 16mm weight bearing cleats.
You can never go wrong with quality nylon plugs and screws, at least 8 x 75mm. The anchors will come with their own instructions – follow them and use a quality masonry drill bit that will give you the correct hole size to work with.
