Tile-Ready Substrate with Mapei Self-Leveling

When your tile contractor specifies Mapei, we source and install Mapei. Ultraplan and Novoplan are the self-leveling underlayment products tile trades trust for warranty. We apply the matched Mapei primer, pour to depth, and cure to schedule. No substitutions, no shortcuts. Free written estimate.

Tile trade standard

Why Tile Contractors Specify Mapei SLU

Tile installers request Mapei self-leveling underlayment because the system warranty path is clear and the product performs predictably under tile. Ultraplan works for thin-to-moderate depth applications; Novoplan handles thicker pours and structural-spec conditions. The Mapei primer bonds the SLU to the substrate permanently, and using anything else voids the warranty.

We install Mapei SLU as a Mapei specialist, with the correct product for your depth, the matched primer applied to profile, and the cure timeline that gets the substrate ready for tile. If the project also needs Mapei waterproofing for wet zones, we coordinate that into the prep. See our full Mapei product range for other applications.

If your spec calls for Ardex self-leveling instead, we install Ardex to the same standard. Both are premium systems; the choice depends on your tile contractor's preference and warranty requirements.

Installation sequence

How Mapei SLU Gets Installed

  1. Assess and select product

    We evaluate the existing substrate, confirm the target depth with your tile contractor, and select Ultraplan or Novoplan based on the application and structural requirements.

  2. Prep and prime

    The concrete surface is diamond-ground to Mapei profile, cleaned of dust and contaminants, and the matched Mapei primer is rolled on for permanent adhesion.

  3. Mix and gauge

    Mapei SLU is mixed to exact water ratio, poured across the floor, and gauge-raked to level. The self-leveling action takes over; we work quickly within the pot life.

  4. Cure and handoff

    The slab cures per Mapei schedule, final flatness is verified against tile-install tolerance, and the substrate is ready for your tile contractor to begin.

Warranty coordination

Respecting the Tile Contractor's Spec

When a tile contractor writes Mapei into the spec, they are protecting their warranty path and their reputation. We honor that spec completely. No generic primer, no product substitution, no cost-cutting. The substrate gets Mapei as specified, and the tile trade gets the foundation they expect.

If substrate damage or old concrete requires repair before the SLU pour, we use Mapei repair products to maintain system compatibility. Explore our other brand specialties for additional concrete services.

Common questions

Mapei SLU Questions Answered

Product selection, primer requirements, tile coordination, and cure timing.

Ultraplan for feather-to-moderate depth pours; Novoplan for thicker pours and structural-spec applications. We pick based on the substrate condition and target depth confirmed with the finish-flooring installer.
Because they trust the Mapei system warranty for their tile install on top, and they have install experience with the Mapei substrate. Honoring the spec keeps the tile-install warranty intact.
Yes. The Mapei primer is calibrated to the SLU chemistry; a generic primer or no primer voids the system warranty and risks delamination. We use the matched primer always.
Not typically; Mapei SLU is designed as substrate for finish flooring. For polished-as-finish projects, a different product family is the right call.
Per Mapei spec, typically within a day or two depending on product and depth. The tile installer's spec also matters; we coordinate the cure handoff with them.

They installed Mapei to spec, including the matched primer. My tile install warranty stayed intact, which is why I keep requesting them on projects with Mapei specced.
