How to attach folding table to brick wall?

[CROBBO]

Hi there,

I'm going to install a folding desk on the inside brick wall of my garage. I will be using a drill with hammer mode. I also have a level. The desk will be used for light craft applications and won't be exceeding 20kgs of items on it at a time. When upright, I want the surface to be roughly 80cm up from the ground so that it can be used from a seated position.

I'm looking to purchase the following –

Carinya Folding Spring Loaded Bracket x2

Specrite 1200 x 600 x 18mm Golden Teak Acacia Panel

https://www.bunnings.com.au/specrite-1200-x-600-x-18mm-golden-teak-acacia-multi-use-panel_p0456528

I have a few questions and would be grateful for any help before I get started –

• Will the Carinya brackets be sufficient for holding up the desk? The panel used for the desk weighs 7.6kg. The bracket length is 315mm and will be running along the 600mm side of the panel. 
• What type/size of screws/bolts will I need to attach the Carinya brackets to the brick wall? I'm unsure if anchors or dynabolts are suitable.
• What size screws will I need to attach the desk to the brackets?
• Any advice for how best to go about this task?
  – Do I attach the desk first to the brackets, then mount to the wall?
  – OR do I attach the brackets to the wall first before mounting the desk?
• Anything else I've missed! 😀

Thank you!

Morning @CROBBO here are the answers to those questions

Q: Will the Carinya brackets be sufficient for holding up the desk? The panel used for the desk weighs 7.6kg. The bracket length is 315mm and will be running along the 600mm side of the panel.

A: Yes the brackets are designed to carry up to 50Kg's this includes the weight of the items sitting on the desk. The most important factor here is to use the right sized drill bit for the wall anchors and suitable screws to fix the desk to the brackets.

Q: What type/size of screws/bolts will I need to attach the Carinya brackets to the brick wall? I'm unsure if anchors or dynabolts are suitable.What size screws will I need to attach the desk to the brackets?Any advice for how best to go about this task?

A: The easiest to use which are my "go-to" fasteners are these "Ramset multipurpose anchors" which I used to hang a dryer on a brick wall for a client on Sat. Each fastener has a holding strength of 32kgs and you will be installing 6/bracket. 

Q: Do I attach the desk first to the brackets, then mount to the wall or do I attach the brackets to the wall first before mounting the desk?

A: Brackets to the wall first. First mark the centre of the desk position on the wall. 900mm is a good height for a worksop desk. The most important consideration is that we want to align as many of the bracket's 6 holes in brick and not the soft mortar. The same consideration when spacing them. The holes should be around 20mm in from an edge to avoid the brick possible breaking/cracking during the drilling process. With 6 anchor points/bracket, a couple of them in mortar will be fine. So, you might need to run the pencil line horizontally 20mm away from a mortar line if 900mm lined up within that distance.

Using your level run a pencil line 450mm left and right. Then at 400mm again using your level run a pencil line plumb (level vertically) down 350mm. Position each bracket level with the top of the line and with the right bracket holes along the right edge and mark the holes. This will put then at around 200mm in from the edge of the desk. This is where you might need to position the brackets left or right to avoid mortar. 

You will need an 8mm masonry bit to drill the holes. Start slowly until the drill has made some depth to avoid the bit walking off the mark. Don't worry if you go into one or more of the brick voids as there will be still enough depth for the actors to work. Blow out the debris and then tap in the anchors with a hammer. Holding the brackets in place, start installing each screw. You can use a drill driver until each screw is all the way in, then I like to finish the last bit with a screwdriver until I can't turn them by hand. PPE for this job will be ear and eye protection.

Position the board central to the hinges (600mm). Then it's safe to use these 20mm wood screws to secure your 18mm desk top as the thickness of the bracket metal will be 2mm or greater. They don't require a pilot hole, just drive them straight in.

Q: Anything else I've missed! 

A: Nope!

Hi @CROBBO,

You already have all the good advice and I will leave you with my heavy duty version.

The legs swing out and the workbench folds down with same load capacity as four legged workbench.
