Sealing your mosaic is the final step—and it’s all about protection. A good sealer helps lock everything in, making your piece more durable and resistant to moisture, stains, or wear (especially if it’s going outdoors or getting regular use). It also enhances the colours and gives your design a beautiful, finished sheen. After all the work you’ve put in, sealing helps make sure it lasts.
