It is for interior applications only. \u003cspan data-state=\"closed\" class=\"inline-flex\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eType 1 has excellent grab on tiles up to 12\" x 12\" (30 x 30 cm), is easy to apply with a smooth consistency, and has an extended open time — making it a practical choice for backsplash installations and wall tile where working time matters. No mixing required — open the pail and apply. \u003cspan data-state=\"closed\" class=\"inline-flex\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eIt's rated for intermittent wet areas such as tub and shower surrounds, and works over concrete, cement backer units, properly prepared drywall in dry areas, and exterior-grade plywood for countertops. Maximum tile size is 6\" x 6\" on floors and 12\" x 12\" on walls. Not for exterior use, steam showers, submerged applications, or radiant heat systems. \u003cspan data-state=\"closed\" class=\"inline-flex\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThe 1-gallon is suited for smaller tile projects, repairs, and single-wall installations.

mortar?\u003c\/strong\u003e Mastic is a premixed acrylic adhesive — no mixing, immediate use, extended open time. Thin-set is cement-based and mixed with water. Mastic is convenient for interior walls and dry areas; thin-set is required for wet areas, exterior use, large-format tile, and radiant heat.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eCan it be used in a shower?\u003c\/strong\u003e For intermittent wet areas like tub and shower surrounds only, where service requirements don't exceed ANSI A136.1 Type 1.
