Interlock & Paver Sealing in Kitchener

Usually, yes. Once joints lose their sand, water gets in, freezes and shifts the pavers, and weeds and ants move in. Sealing over empty joints would not fix any of that. So we clear out the old sand and weeds, refill with polymeric sand, compact it and seal once everything is dry.

That depends on the finish. Natural or matte leaves the colour almost untouched and keeps the most grip. Enhanced or satin makes it a little deeper. Wet look or gloss goes dark and glossy, but it can be slicker when wet, so natural suits steps better.

Pavers need to be dry, with a few dry days ahead. That puts the season between late spring and early fall, above the minimum temperature on the sealer label. Booking before winter means salt and freeze-thaw meet a protected surface. Brand-new interlock is usually left to weather for a season first.

It helps a lot. A sealed surface and firm polymeric joints keep more water and salt out, and that cuts the freeze-thaw damage that empties joints. It is protection, not a cure-all, so plan to reseal every few years, once water stops beading on the surface.
