For: Brooklyn apartments, basements, laundromats, commercial spaces
NYC‑র বিল্ডিংগুলোতে সাধারণত দেখা যায়:
পুরনো concrete slabs (100+ years old buildings)
Uneven floors / dips / humps
Moisture issues (basement, ground floor)
Patchwork repairs from previous tenants
Radiator leaks, plumbing patches
Mixed substrates (wood + concrete + patch)
তাই self‑leveling underlayment খুবই গুরুত্বপূর্ণ।
High spots → grinder
Low spots → patch or self‑leveler
Moisture test (especially basements)
Old adhesive removal (black mastic / cutback)
Loose boards tighten
Squeaks → screws + construction adhesive
Add 1/4" or 1/2" plywood if needed
No self‑leveler directly on wood without primer + lath (unless product allows)
Transition areas smooth করতে self‑leveler best
Old tile removed হলে surface grinding দরকার
Uses:
Interior floors leveling & smoothing
1/8" to 2.5" পর্যন্ত লেভেল করতে পারে
Fast hardening (tile install 2–3 hours)
Suitable for: tile, stone, carpet, wood flooring
Pump বা manual — দুইভাবেই apply করা যায়
Low shrinkage, strong bond
Ideal for NYC:
Uneven apartment slabs
Commercial spaces (laundromat, deli, office)
Old concrete with dips
Remove dust, debris, old adhesive
Vacuum + damp mop
Oil/grease spots → degreaser
Cracks → fill with patching compound
Most self‑levelers require primer for:
Bonding
Preventing pinholes
Moisture control
SikaLevel 125 → use Sika primer (per manufacturer).
Clean bucket
Cold water (NYC summer heat slows working time)
Mix lump‑free
Use paddle mixer
Start from lowest point
Product will flow & self‑level
Use smoother/guage rake if needed
Tile: 2–3 hours (SikaLevel 125)
Vinyl/wood: follow manufacturer (usually longer)
Heavy traffic: 24 hours
NYC apartments → uneven floors common → self‑leveler almost mandatory.
Tile needs flat surface → dips cause cracking.
Uneven floors → clicking noise, movement.
High spots → hollow sound, bounce.
Floor uneven more than 1/8"
Old concrete slab
Basement moisture
Tile installation
Customer complains “floor feels wavy”
Primer
Mixing paddle
5‑gal bucket
