Structural condition first
Flooring should not be used to hide movement, loose concrete, failed repairs or an unstable base. Repair the slab before specifying the finished surface.
Apollo Pickleball · installation planning
Subfloor preparation for pickleball flooring starts with a stable, clean and correctly prepared concrete base.
Existing concrete should be inspected, repaired, mechanically prepared and moisture-checked before a pickleball flooring system is installed. The flooring follows the quality of the base beneath it, so cracks, uneven areas, contaminants, excess moisture and drainage problems should be addressed before the finished sports surface is laid.

Technical overview
Existing concrete preparation sequence
The sequence below is taken from Apollo's current pickleball subfloor preparation guide. The exact preparation method, primer, moisture treatment and adhesive system still depend on the selected flooring system and actual slab condition.
0101 · Inspect the existing base
Structure + conditionCheck cracks, movement, loose concrete, uneven areas, moisture issues, old coatings and surface contamination. The slab should be structurally stable before flooring work begins.
0202 · Check surface flatness
Smooth + levelIdentify high spots, low spots, previous repairs, waves and uneven joins. Grind high areas and use suitable levelling compounds where required.
0303 · Repair cracks + damage
Repair before coveringRepair minor static cracks with suitable compounds. Expansion joints should be treated correctly rather than simply covered, and loose or deteriorated concrete should be removed and repaired.
0404 · Remove contaminants
Clean concreteRemove dust, oil, grease, paint, old adhesives, sealers, silicone contamination and debris before installation.
0505 · Mechanical grinding
Diamond grinding recommendedMechanical grinding helps remove weak laitance and contaminants and improves the prepared surface for bonding. Vacuum thoroughly after grinding.
0606 · Moisture testing
Test before installationExcess moisture can contribute to adhesive failure, bubbling and flooring separation. Moisture barriers or sealers may be required where readings are too high.
0707 · Outdoor drainage
No standing waterOutdoor slabs should drain correctly without ponding. Minor falls are generally recommended for outdoor pickleball courts.
0808 · Primer / sealer
System-specificA primer or moisture sealer may be required depending on the flooring system and slab condition. Follow the selected flooring manufacturer's installation specification.
0909 · Final cleaning
Dry + dust-freeVacuum the full slab and confirm the surface is dry, clean and free of debris immediately before installation.
This guide is for project planning and does not replace slab assessment, flooring-manufacturer instructions or site-specific installation advice. Final substrate preparation, moisture treatment, drainage, primers, adhesives and joint treatment are confirmed for the selected system and site conditions.
Preparation sequence
The finished court is only as reliable as the base beneath it.
For bonded and semi-permanent sports-flooring systems, slab stability, flatness, cleanliness, moisture and drainage should be checked as one preparation package rather than as separate afterthoughts.
Project fit
Key checks before the sports surface is installed.
Expansion joints need correct treatment
Existing expansion joints should be identified and handled correctly for the selected flooring system rather than simply bridged over without review.
Moisture can undermine adhesion
Complete moisture testing before installation and confirm whether a moisture-control layer or sealer is required for the selected adhesive and flooring system.
Outdoor drainage matters
A pickleball surface does not correct a slab that ponds. Falls, drainage paths and low points should be reviewed before the court surface is installed.
Portable and permanent systems differ
Portable systems may use loose-lay or perimeter-fixing methods, while permanent installations commonly use full adhesive bonding. The preparation standard should match the selected installation method.
Final clean means installation-ready
The prepared slab should be stable, level, mechanically prepared where required, dry, dust-free and ready for the exact adhesive or flooring system being used.
