Tiling Over Existing Concrete Steps & Landing

If your concrete entrance steps and platform are sound—no major cracks, spalling, or heaving—you can tile directly over them using polymer-modified thin-set mortar rated for exterior use. Skip glazed or polished tile; they're dangerously slippery when wet or icy. Choose textured porcelain, unglazed quarry tile, or natural stone with a non-slip finish.

Clean the concrete thoroughly, etch if smooth, and apply a bonding primer if recommended by the mortar manufacturer. Use a waterproofing membrane (like Schluter-DITRA) over the concrete for added crack isolation and moisture protection, especially in freeze-thaw zones.

Grout with sanded, polymer-modified grout and seal joints. Slope treads ¼ inch per foot for drainage. This system lasts decades when prepped right.
