Driveway Sealer Coverage
When and How to Seal

No Brasil

Impermeabilização de laje/garagem: R$30-80/m² profissional. DIY com manta asfáltica: R$20-40/m². Impermeabilizante líquido (Vedacit, Sika): R$15-30/m². Para garagem de 35 m²: R$525-1.050 DIY ou R$1.050-2.800 profissional.

Tipos

Manta asfáltica: o padrão para lajes e banheiros no Brasil. Impermeabilizante líquido: mais fácil para DIY. Cristalizante: para reservatórios e piscinas. A impermeabilização é o item mais negligenciado e mais caro de reparar depois.

⚡ CalcWolf Insight

The best driveway sealing tip most people miss: clean the driveway with a pressure washer or strong detergent AND let it dry completely (24-48 hours) before sealing. Sealer applied over dirt, oil, or moisture peels off within a season. Proper surface prep is 70% of a good sealing job — the actual application is the easy part.
