Grout
A joint cross , also known as a tile spacer , is an aid that is used when laying rectangular tiles . The legs of this four-legged cross, which is mostly made of plastic, are a few centimeters long and have the width of the joints to be created between the tiles . Their thickness is slightly smaller than the thickness of the tiles to be laid. In every 90 ° inside corner a tile joins the cross, or every rectangular tile is surrounded by four crosses after gluing . Before grouting , the crosses are removed or pressed into the tile adhesive that has not yet hardened .
As a variant, there are 3-leg joint "crosses" ("T-shape") for laying tiles up to a wall corner.
For laying relatively thick floor slabs on sand or gravel, mostly outdoors, there are tile crosses with a floor ring underneath. They are less high than the panels and remain in the joints. One corner of each of the neighboring plates lies on the bottom ring, so that they are all positioned at the same height and have no overlapping teeth .
