Sealer Coverage
When to Seal

Couverture

Bonne surface : 3-4 m²/L. Moyenne : 2-3 m²/L. Dégradée : 1,5-2,5 m²/L. Toujours 2 couches. Allée de 35 m² : 20-25 litres. DIY : 50-80 €. Professionnel : 200-400 €. La préparation (rebouchage + lavage) est 80% du travail.

Application

10-30°C, sans pluie prévue 48h. Surface complètement sèche. Ne pas rouler dessus pendant 48h. Rescellez tous les 2-3 ans — pas chaque année (cause accumulation).

⚡ CalcWolf Insight

Clean the driveway with a pressure washer and let it dry 24-48 hours before sealing. Sealer on a dirty surface peels within a season.
