Proper substrate preparation is the foundation of every lasting tile installation. Assessment, levelling, grinding, and screeding — done right the first time.

The most common cause of tile failure isn't the tile — it's what's underneath it. Insufficient substrate flatness causes lippage. Movement in the substrate causes cracking. Poor adhesion causes debonding. JSR Tiling's floor preparation service eliminates these risks before a single tile goes down.
We assess every substrate on its own merits, specify the correct preparation method, and carry out the work to the standard required for the tile format and application — whether that's a domestic bathroom or a large-format commercial floor.

Floor Preparation Questions
Why is floor preparation important before tiling?
Tile failures — cracking, lippage, debonding — almost always trace back to inadequate substrate preparation. A flat, stable, clean substrate is the foundation of any quality tile installation. We never skip this step.
What floor preparation services do you offer?
We offer substrate assessment, floor grinding, self-levelling compound application, screeding, ply overlay installation, and existing tile removal. The right method depends on your floor type and condition.
Do I need floor preparation for large-format tiles?
Yes — large-format tiles (600mm+) have tighter lippage tolerances than smaller tiles. Self-levelling compound or grinding is typically required to achieve the substrate flatness needed for a lippage-free result.
Can you prepare floors over underfloor heating?
Yes. We have experience preparing substrates over both electric mat and hydronic underfloor heating systems, using appropriate levelling compounds that are compatible with heated floors.
