Phase 1: Dry removal (Day 1)

Remove all loose debris before any wet cleaning. Construction dust mixed with water creates a slurry that's harder to remove than dry dust.

Vacuum with a soft brush attachment. Sweep corners and edges. Peel off any protective tape. Scrape off paint drops with a plastic scraper - never metal on polished stone.

Phase 2: Cement haze removal (Day 2)

The grey film on tiles is dried cement residue. It needs a specific product - regular cleaners won't dissolve it.

Product: Lithofin KF Cement Residue Remover

For acid-sensitive stone (marble, limestone, terrazzo): use Lithofin MN Builders' Clean instead, diluted 1:10. For ceramic, porcelain, granite: apply KF Cement Residue Remover diluted 1:5. Pre-wet the surface, apply, let dwell 5 minutes, scrub with a nylon brush, rinse thoroughly with clean water.

Phase 3: General deep clean (Day 3-4)

After cement haze is gone, address residual grime, grout staining, and construction marks.

Product: Lithofin MN Power-Clean

Dilute 1:5 for heavy soiling. Apply in 2 m² sections, scrub, and rinse. Change the rinse water frequently - dirty rinse water redeposits grime. Two cleaning passes are usually needed.

Phase 4: Protection (Day 7-10)

Wait at least 3 days after final cleaning for the stone to dry before sealing. Moisture trapped under sealant causes white haze.

Product: Lithofin MN Stain-Stop

Apply one coat to all stone and unglazed tile surfaces. A second coat for kitchen countertops, bathroom floors, and heavily used areas. Don't forget edges, thresholds, and window sills.
