How do you maintain stamped concrete in New Brunswick?

Maintaining stamped concrete in New Brunswick comes down to one primary task: keeping the sealer in good condition. Everything else — colour retention, texture preservation, surface integrity — follows from that. Plan for an annual inspection and resealing every 1-3 years depending on sealer type and exposure.

Annual inspection in spring. After the final freeze-thaw cycles of NB's winter, examine the stamped surface closely. Look for areas where the sealer has worn thin (the surface looks dull or chalky rather than having the uniform sheen of fresh sealer), any peeling or bubbling of the sealer film, hairline cracks at joint lines or elsewhere, and any surface scaling or colour fading. Catching these early — before another full season of UV exposure and freeze-thaw cycling — lets you address them at low cost.

Resealing schedule. Acrylic sealers (the most common on stamped concrete) typically need reapplication every 1-2 years in NB conditions. The combination of UV exposure in summer, freeze-thaw stress in winter, and physical wear from foot traffic wears acrylic sealers down faster than in milder climates. Polyurethane and polyaspartic sealers are more durable and can last 3-5 years but cost more. To test whether resealing is needed: sprinkle water on the surface — if it beads, the sealer is still working; if it absorbs, it is time to reseal.

Resealing process. Clean the surface thoroughly before applying a new coat of sealer. A light pressure wash removes dirt, mildew, and salt residue. If there is old sealer buildup from multiple applications (the surface looks thick, cloudy, or is peeling), use a chemical sealer stripper before applying a new coat. Applying fresh sealer over failing old sealer creates an adhesion problem and will peel faster. Apply the new sealer with a low-pressure sprayer or roller in cool, dry conditions above 10 degrees Celsius with no rain forecast for 24-48 hours.

Winter care. Avoid using sodium chloride (road salt) on stamped concrete at any time, but especially on a surface where the sealer is worn. Salt accelerates scaling and bleaches colour. Use sand for traction. If you must use a de-icer, calcium magnesium acetate (CMA) is the least aggressive option for concrete surfaces. Keep downspouts directed away from the stamped area — salt-laden snowmelt draining across an unsealed section causes rapid colour damage.

Crack and chip repair. Small chips at pattern edges can be filled with a colour-matched concrete caulk or flexible repair compound. Colour matching is imperfect, but a careful repair is far less visible than leaving the chip exposed through another NB winter. For larger repairs or significant cracking, a stamped concrete contractor can assess whether a localized repair is feasible or whether a panel needs to be resurfaced.
