Many people will purchase Federal Brace countertop supports because they are looking to limit knee knocking under sitting areas. Today, we are going to review how to install a granite countertop to a knee wall such as a breakfast bar installation.
The Freedom Countertop bracket is a ninety-degree piece of steel without a gusset (the piece that connects the bottom and top of the L-bracket). It is a quarter inch thick up to 12 inches and goes up to .375 inch thick 14X14 – 16X16 and up to a 1/2 inch at 18X18 –20X20.
You want to make sure you have the right number of brackets - you want to have a bracketed support every 12 to 18 inches and no more than four inches of over-hang extending beyond the end of the bracket. Every application is different and we cannot be there to advise an application we cannot see, you want to consult an installer, but some general tips when speaking to the installer are…
In most instances, customers using the Freedom style countertop supports are attaching the brackets directly to the studs and covering with wall board material. You will want to attach the Freedom hidden countertop brackets with lag screw fasteners. You will go from flange to flange making sure the brackets are level. You can use a four-foot level to do this. You can put some paneling on the front of the knee wall to hide the down flange of the brackets. You will clean the brackets and put adhesive on the brackets. When you place the countertop you want to make sure they sit evenly and all the weight is being properly dispersed across the brackets. After an appropriate amount of time for them to dry you can slide over some chairs and you’ll be all set to go.
If you’ re looking to put the supports on top of sheet rock dry wall, you are going to need some kind of backing on the wall, like a backer board. When you position the brackets you want to make sure that the supports are carrying the load not the backer board. You would attach the backer board with several rows of nails going into the stud. A quarter inch lag bolt will then go into the backer board when attaching the brackets themselves.
However, if you want to attach the bracket on the studs on a wall that is finished you will need to recess them into the sheetrock and make sure you connect them directly to the stud using lag screws. Once the wall has been repaired, you can apply granite adhesive to the tops of the brackets – this also goes for when using the Bracket Backers™ as well.
You will clean the brackets and put adhesive on the brackets. Be careful not to let the glue drip off the side when you go to place the granite.
I hope these basics lead to a better understanding of the installation on this popular style of bracket. Thank you very much and have a great day. ~ SK
