Yes, they work great on wall tile. For removal, just use a white rubber mallet (or something similar) to strike them. Be sure to strike them on the thin side of the leveler piece in a motion that follows the grout joint where they are installed. They will easily break free.
We would never recommend going a step down in a specified thinset, but if the only reason you are using the “Large Format Style “ thinset is to hold the tile in place, then it makes sense that it would work. You must always be sure the thinset mortar used bonds properly to the substrate, is suitable to bond to the back of the tile, and is appropriate for the type of movement expected. Back buttering of the tiles is always recommended for larger tile, but not because of our system, it is because the industry recommends back buttering of large tiles in any installation. Of course the goal is 80-100% coverage of thinset (depends on the tile type and expected use), so however you get there is fine.

Of course the goal is 80-100% coverage of thinset, (depends on the tile type and expected use) so however you get there is fine. Back buttering is the most common and preferred method.
It is always a good idea to help the weakest point of any installation (corners) by adding a small amount of thinset in case you missed something in your back buttering or general installation techniques. The best floors have full thinset coverage and the corners are the easiest to miss when trying to achieve this goal. Because of our specific corner design that allows mortar in the corners of the tile to have direct contact with the floor, we have helped you to achieve this. We would not discourage you from creating small dots of thinset in your corners if if gets you closer to your goal of full coverage. However, it has nothing to do with the Leveling Spacers™ system in particular. It is just a professional’s installation preference on how to acheve proper coverage. All tile installers have their preferences, and many like to put small dots of thinset in the corners before setting the tile in place.
You should always follow manufacturers recommendations on the ratios of water to powder in your thinset mix. So much of the ability to answer that question depends on tile size, floor conditions, patterns etc. However, it has proven helpful in most instances to make your mix a little softer….as long as you are still within manufacturer tolerances.
No, you will still need to make your subfloor relatively flat for the best installation. However, using a leveling system in general will be able to heal the minor variations in a normal subfloor without the more extensive time needed to create a perfectly flat subfloor.
A leveling system is absolutely essential in a thin tile panel installation. We recommend selecting a Large Format type thinset, back buttering of the panels with the trowel grains running north and south in the direction of the smallest dimension of the panel. The floor/wall thinset grains should run in the same direction so as not to entrap air pockets. Leveling Spacers™ should be placed no more than 24” apart, and approximately 2” from each corner. Please do not put Leveling Spacers™ in the corners on a thin tile installation. We have not had any reported problems, but it just make sense that thin tiles would break if you did not get the perfect thinset coverage below the surface. It is not worth the potential risk. Next, place the tile according to your preferences and work to eliminate any air pockets using your preferred method. You will love the results.
A leveling system is absolutely essential in an extra large tile installation. We recommend selecting a Large Format type thinset, back buttering of the panels with the trowel grains running north and south in the direction of the smallest dimension of the panel. The floor/wall thinset grains should run in the same direction so as not to entrap air pockets. Leveling Spacers™ should be placed no more than 24” apart, and approximately 2” from each corner. Please do not put Leveling Spacers™ in the corners on an extra large tile installation. You will need the extra strength to position the tiles flush with each other. Next, place the tile according to your preferences and work to eliminate any air pockets using your preferred method. You will love the results.
Check for floor/wall flatness. Apply underlayment leveling products as needed to floors or fix walls according to TCNA industry standards.
Use ½” notched trowel or larger for large format tiles. See TCNA guidelines for proper mortar coverage requirements. Back butter tiles if necessary.
We recommend LHT style thinset mortar for any large format tiles, per industry standards.
Use only one leveler per intersection. Other systems require 3 or 4 per intersection because they have solid plastic on the bottom which would break the direct bond in the weakest point of any installation, namely the corners.
Leveling Spacers™ patented “I shaped footer” allows installation at the intersection without compromising the bond of tile to thinset to the subfloor/wall.
Never leave a separation of more than 24” between levelers. They are not designed to span greater than 24” apart.
If the tiles themselves are bowed, you may need to apply more levelers to shape them into place.
Before inserting the wedges, tap the tiles gently into the mortar using a rubber mallet to obtain optimum transfer of mortar to tile. Use your hands to determine if certain tiles need to be tapped in slightly more, or if some tile need to be lifted and more mortar installed below.
Insert wedges until strong resistance occurs. No need to over tighten. Only apply enough pressure to level the tile surfaces.
Specialized tools may be used but due to the slant of the wedge teeth, they are not necessary to obtain perfect pressure. It is really a user preference.
If sideways spacing is desired you can either use a standard spacer or use the leftover portion from the leveler broken off the day before. The upper broken-off portion of the leveler from the day before, is now basically a horseshoe spacer.
Don’t be afraid to use the levelers in the corners because our patented “Window Wedge” allows the installer to see if the tiles are properly aligned. This is unique to Acufloor™.
When the mortar is dry, simply remove the levelers from the installation by swiftly kicking sideways, sliding your foot parallel to the floor. For wall removal, use a rubber mallet or other non-marking method, sliding sideways and parallel with the surface.
Do not strike the leveler at an angle to the floor (downward swing). It is not dangerous, but it will often result in improper breakage causing extra work for complete removal. No need to remove the wedges. They actually help the removal.
Leveler should easily break all the way down the footer below the tile bottom surface. This will not impede any grouting process. In the unlikely event that a portion of the leveler occasionally remains, simply remove it with pliers, knife or whatever method you are most comfortable.
