This is the sample of Kastar Ceramic Tile Sealer. This is another sample of other brands. We fold two samples at the same time. The other sample is broken. Kastar is as good as before. Kastar added the toughening agent from Belgium makes the tile sealer more flexible and easy to cope with thermal expansion and cold shrinkage, so Kastar has better flexibility and toughness.
