Should I seal my concrete driveway after washing?

Sealing your concrete driveway is highly recommended after professional washing, especially in Quebec where freeze-thaw cycles are destructive. A quality sealer penetrates concrete pores and creates a barrier against water, salt and oil stains. Without sealer, water penetrates the concrete, freezes in winter, and causes cracks and spalling. We recommend applying a penetrating transparent sealer every 2 to 3 years, ideally after pressure washing that opens the concrete pores. Aqua-Net can refer a qualified contractor for sealing, or include it in a complete package depending on the season.
