SGM Unsanded Thin Set is a fine-textured, polymer-modified adhesive mortar designed for setting tile in narrow grout joints (typically 1/8 inch or less). Its smooth consistency makes it ideal for delicate tile and smaller grout spaces, providing reliable bond strength and easy application on floors and walls. Unsanded Thin Set is a dependable choice for ceramic, porcelain, and stone tile installations that require a more refined mortar for tight joints and detailed work.
