When to Seal

No Brasil

Selante/impermeabilizante para piso externo: R$20-50/litro, cobertura 3-5 m²/L. Garagem de 35 m²: 15-25 litros, R$300-1.250. Marcas: Vedacit, Sika, Viaplus. Aplicar 2 demãos com 24h entre cada.

Quando Aplicar

Quando a água se absorve ao invés de pelar. Geralmente cada 2-3 anos. Superfície seca, 15-30°C, sem chuva em 48h.

⚡ 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.
