It is best to mount the unit to the substrate first, if this is an option. We are aware that many people are installing the BT-17 low for that very purpose. the capacity can be substantially increased by installing additional fasteners and/or mounting the nit directly to the face of the substrate. The BT-17 has a 100 lb live load capacity due to the amount of fasteners supplied with the unit and based on a retro-fit, or over the tile, method of installation. Review also the items posted in that section for pertinent information! Most Better-Bench product installation guidelines apply to the BT-17. You will notice this size has several holes in the tray, which is designed to allow the mortar mix to slightly penetrate through, in turn providing a surface for the tile to adhere to. The BT-17 was designed to be used as a shelf and is therefore installed at a higher level than the bench seats, hence leaving the bottom visible. If you are using the BT-17 or BT-17S, we do require that you tile the underneath of the bench. Remember, you must leave the weep hole clear of any obstruction so that any penetrating moisture will be able to escape from the interior of the bench. you may tile the bottom, if desired, by using a metal bonding tile mastic, or by simply screwing a piece of backer board substrate material to the bottom if the bench with galvanized flathead screws. The alloyed aluminum will not rust or corrode, and it leaves a smooth metal surface exposed that will not harbor mold or mildew growth, as well as it is easy to clean. It is mounted down the low and therefore the bottom is not visible. It is not necessary to tile the bottom of the BB-30, BB-24, or ADJR bench. allow the unit to set sufficiently prior to beginning your tile process. You will then apply this mix to the front face and screed it flush with the top and bottom edge of the channel.
Then add a small amount of water to the remaining mix to make it a little bit stickier. Allow the mortar to build up about 1/4 – 3/8 of an inch along the back wall(s) of the unit and screed it flush to the front lip to provide adequate drainage of the horizontal surface (this is not necessary in “dry” areas). Make sure the material is in all corners completely. Be sure to blend the mixture to the point that all dry powder pockets have been eliminated.įill the entire bench with the mortar, and pack it tight as you go with a wood float, block of wood or even a steel trowel. You will be adding just enough water to allow you to “chop” (a garden hoe works best!) the mixture to consistency that allows you to pick up a handful and shape it into a ball without getting it all over your hands.
under the common name of mason mix, brick mortar, or deck mud. Additionally, you will find this mix at lumber yards, hardware stores, Home Depot, Lowes, etc. Do NOT use Thin-Set mortar! The mix ratio of the described mortar is 4 parts sand to 1 part cement – you may also use a pre-bagged mortar mix which is available at many of the tile locations that stock Better-Bench products. A “dry pack” deck mortar is used to fill the bench.
