Lots of Companies sell products telling you how easy it is to clean your driveway and concrete surfaces outside. Why are they on every radio station and TV Channel offering solutions? They also know that you have to keep applying their solutions year after year.
Like them, we clean your concrete but that’s where the similarities stop. We then treat and seal those surfaces. If moss, mould, gunge etc cannot penetrate the surface, then they can’t get a foothold and won’t be there next year or the year after that.
