About Built with Foam Shims: Our ingenious shims work on ceilings and are great as depth gauges for self-leveling pours. A Wall Flattening Shim Kit includes 900+ shims per box in seven different thicknesses. They are color coded for easy identification, even by installers with colorblindness. Each box covers 5 to 10 showers depending on the quality of the framing.
