Lay mosaic and fill with grout
The basis for each coaster is a natural tree slice. First, select mosaic stones and place them on the tree discs.
The transparent mosaic joint compound is both glue and joint filler. First, glue the stones onto the tree discs.
Use the spatulas to spread the mosaic joint filler into the spaces until they are completely filled and an even surface structure is created.
Due to the high-quality acrylic-polymer dispersion, the joint filler hardens like glass and is weather and weather-resistant after approx. 4-6 hours drying time.
