How to Dispose of Tile Mortar
Thinset mortar is frequently used as an adhesive to set tiles in place. After you have completed a tiling project, however, you can not simply dispose of the leftover mortar by throwing it down the drain. Doing so can lead to clogged pipes and have harmful effects on the plumbing, not to mention the environment. Thankfully for those unfamiliar with the process, you can dispose of mortar quickly and safely with items you may have around the home.
