This Scratch Preventer is designed for use on matt and polished indoor tiles to prevent scratching of tiles during the installation. You can use Scratch Preventer together with Twister 2 Part Levelling System or Traditional 2 Part Levelling System. It prevents sand or cement scratching the surface when the Twister Nut or the Levelling Wedge is being tightened.
You can use Scratch Preventer as a basic tile spacer as well. It is cleverly produced in a way to have four different thicknesses on each side (1mm, 1.5mm, 2mm, 3mm)
