For decades, everyone has applied edging to their pavers using one of four tried-and-true methods: plastic edge restraint, concrete curbing, bond beam, and step edging. In the last few years, Chris Yancey, a professional hardscape contractor, developed a fresh paver edging product called Perma-Edge Paver Edging. In this article, we’ll show you how to use […]
There are three big mistakes that people make when applying sealer to pavers.
- The surface is too hot
- The surface is not dry
- The surface is not clean
Temperature and cleanliness are pretty easy to understand, but how in the world do you tell if your stones are dry enough? Most sealer manufacturers recommend waiting 24 hours before sealing, and we recommend waiting 72 hours just to make sure, but what if it’s been hot and dry or cloudy and cold? Since the moisture tends to linger in the sand joints which you can’t see down into, how can you really be sure?
The Vapor Barrier Test
After waiting the manufacturer’s recommended 24 hours, an easy way to be sure that the surface and sand joints are completely dry is to create a sort of miniature greenhouse over a small test area by taping down a small sheet of clear plastic. The plastic forms a natural greenhouse which warms the surface in the sun. Any moisture that evaporates from the additional warmth will be trapped inside the vapor barrier. If you tape down a sheet of plastic and leave it for at least 45 minutes in the sun, and you have no moisture on the plastic, your pavers are dry enough to seal.
