Run Tile Substrate Acceptance Inspection — Free

Project and Substrate Identification

Inspection area and room location confirmed

Record the exact room, level, gridline, or area being inspected.

Substrate type verified

Identify the substrate material being evaluated.

Note (optional)

Substrate is within approved scope for tile installation critical (required)

Confirm the substrate type and condition match the project specifications and manufacturer requirements.

Yes No N/A

Reference documents available on site

Verify that applicable drawings, product data, and installation instructions are available for review.

Yes No N/A

Surface Flatness and Condition

Surface flatness meets project tolerance critical (required)

Verify the substrate meets specified flatness requirements for the tile format and installation method.

Yes No N/A

High spots, ridges, and abrupt transitions removed

Check for protrusions, trowel ridges, or transitions that could telegraph through tile.

Yes No N/A

Low spots, voids, and surface depressions repaired

Confirm depressions, honeycombing, and voids have been filled or leveled appropriately.

Yes No N/A

Surface is clean, dry, and free of contaminants critical (required)

Inspect for dust, oil, curing compounds, paint, adhesive residue, or other bond-breaking contaminants.

Yes No N/A

Cracks, spalls, and damaged areas documented

Identify visible cracks, spalls, delamination, or other defects that may require repair or isolation.

Yes No N/A

Note (optional)

Moisture and Environmental Readiness

Moisture test results recorded critical (required)

Enter the moisture test method and measured results, such as RH, MVER, or surface moisture reading.

Moisture levels are within acceptable limits critical (required)

Confirm the measured moisture condition is within the limits required by the tile and setting material manufacturer.

Yes No N/A

Ambient temperature and humidity are suitable

Verify site conditions are within the recommended range for substrate preparation and tile installation.

Yes No N/A

No active water intrusion or visible dampness critical (required)

Check for leaks, seepage, standing water, or persistent damp areas that could affect adhesion or performance.

Yes No N/A

Crack-Isolation Membrane

Crack-isolation membrane required by specification

Confirm whether the project documents or substrate condition require a crack-isolation membrane.

Yes No N/A

Note (optional)

Membrane installed in required areas critical (required)

Verify the membrane is present in all specified locations, including cracks, control joints, or high-risk areas.

Yes No N/A

Membrane coverage and overlaps are correct critical (required)

Check that coverage, seams, overlaps, and edge details meet manufacturer requirements.

Yes No N/A

Membrane is fully bonded and free of defects

Inspect for bubbles, wrinkles, fishmouths, voids, or debonded areas.

Yes No N/A

Primer and Final Acceptance

Primer type matches substrate and setting material critical (required)

Confirm the primer used is compatible with the substrate and tile installation system.

Yes No N/A

Primer applied uniformly and per manufacturer instructions critical (required)

Check for full, even coverage without puddling, missed areas, or over-application.

Yes No N/A

Primer cure time verified before tile installation

Confirm the primer has cured or dried for the required time before setting tile.

Yes No N/A

Substrate accepted for tile installation critical (required)

Final approval that the substrate is ready for tile installation without outstanding deficiencies.

Yes No N/A
