Don't follow step 6 or 8 of the instructions for assembling a IKEA Långudden sink. There's a better way to do it. Here's why.

I just finished installing an IKEA kitchen. All went well, except for the sink. I usually always follow the instructions carefully, because i know that other humans have spent a lot of time trying to figure out the best way to assemble, so chances are, the instructions provide one of the easiest and most successful ways to assemble a product. 

However, even though the entire kitchen assembling project went well, the sink gave me major headaches:

  1. It was not clear to me, even though it is written in the manual, that spreading the silicon on the cut part of the kitchen top as specified on step 6 of the manual, servers only to make the cut part impermeable to water and moisture. It's purpose is NOT to prevent water from leaking down under the kitchentop: for that there is the big black sealing which does a pretty good job. 
  2. Don't smear the silicon with a paintbrush. That just doesn't work. It will just make a mess. Instead:
    1. blow and brush off any sawdust from the cut part. There is lots trapped in there, and it will just make a paste with the silicon.
    2. apply the silicon as depicted in step 6. 
    3. use an old credit card or spatula to spread the still soft silicon evenly, to create a nice uniform and protecting silicon layer. Remember: the silicon doesn't have to close any gap between the sink and the kitchen top!
    4. ideally you would want to let the silicon dry here, so that there is not risk that it will get removed while inserting the sink.
  3. Now for step 8: uniting the top with the sink. The sink i had, came with the 110385 brackets, the ones that look like the figure here:

    The instructions say to clip them on the sink, then lay the top over the sink, then snap them on. However this step doesn't work because some are hard to clip on, and some get trapped under the kitchen top. So here's how it works much much better.
    1. Disassemble each bracket by unscrewing the screw completely off, so that the plastic part is now free of screw and bracket.
    2. Snap the plastic part on to the sink, as shown in the figure (more or less)
    3. Now lower the kitchen top on to the sink, as depicted in the figure. Now there will be no bracket getting stuck under the top.
    4. At this point it will be easier to screw the screw and the bracket back into the plastic part. Start by placing the screw with hands in the plastic snap-on piece.
    5. Make sure the bracket is into it's closed position, as depicted i the figure:
    6. Now you can use an electric screwdriver to tighten the screws, even though the instructions say not to. But make sure the clutch is set to it's softest setting! And stop right when the screw reaches the bottom, then manually tighten. You want this to be as tight as possible, just before stripping the screw, so that the seal on the sink works it's magic.
  4. Voilá! The sink is assembled. Way easier than the suggested way.
