The traditional system featuring wedges has a very simple functioning system and it is made out of only two parts. Thus, you will have the wedges, of course, and the clips. While the wedges are the same and can be reused, clips are available in a different size, to meet different grout line sizes, and need to be replaced for every tiling project. One clip will go underneath two tiles that are placed next to one another. Then the wedges are inserted into the clips, with a pushing movement. These two together will apply pressure on the entire tile, keeping it tightly in place and reducing the occurrence of lippage. Just make sure to insert the wedges carefully into the clips, not moving the tiles during this process. In the worst-case scenario, if you don't do this part right, the clip breaks, and you'll have to perform the tile installment part all over again.
At the end of the project, once the adhesive is completely dried, the wedges will be removed with the help of a mallet or hammer. This procedure seems simple, but it can cause additional work to the project, which can span over a whole day. Such a thing can happen when the clips don't come off as expected, requiring more effort to remove them and set the wedges free. Then there's the worst-case when the clips don't break and you'll need to force them with stronger hits. This can lead to a deformation of the tiles, which will impact the aspect and quality of your entire work.
The quality of the used materials always matters and impacts the final result. When it comes to wedges, it would be recommended to choose those that are thicker. This type of wedges is more effective in keeping tiles fixed in their place. The clips should be flexible, but sturdy at the same time, to inflict a good amount of pressure on the tiles while being easy to remove. Choosing the right clips will influence your work, as they need to keep the tiles in position, and break when you need to remove them.
Start the project by spreading the adhesive on the work surface. Then take the self-leveling spacers and insert them in the right place, underneath the set tiles so that they cover all their four sides. Traditional spacers should be used as they are meant to, straightening up the corners this way. In case you're installing large-sized tiles, you may need to double the number of spacers you're using, utilizing two of them for each size.
Position the tiles adequately and fix them in their place with a rubber mallet, by tapping on them gently.
Take the wedges and insert them in the clips with the help of pliers that have adjustable traction. At this part, be careful not to exceed the breaking point.
Wait until the adhesive dries completely. Once this happened, it is time to remove the spacers. You can use pliers, a mallet, or even your boots to kick the spacers until they break free.
