White haze on paving stones is a serious concern when using stabilized jointing material, such as polymeric sand, for your patio or driveway project. During the installation process it’s easy for stains to occur in the form of a white haze if the chosen product isn’t installed properly. This white residue is often called polyhaze.
When installing polymeric sand in the joints of pavers, it’s suggested that the installer spray the paved area with water and leave time to dry. Special attention needs to be given to not overwater the area, as this will result in the leeching out of the binders, which can then lead to that white haze on paving stones. Any of the excess dust from the sand that’s left on the surface prior to watering will also create a haze, so it’s imperative to remove all of this dust prior to the soaking stage. It’s important to note that polymeric sand does not allow for a heavy spray of water that would clean the surface, as you will most likely wash out the binders and even the sand.
With a 2-stage watering system unique to Envirobond, Envirobond products, EnviroSAND or EnviroSTONE, eliminate the risk of white haze paving stones. Envirobond’s plant based glue activates immediately with water so a light mist will hold the surface in place. You’re then able to follow up with a heavy spray, which will instantly clean the white residue off the paving stones as well as further saturating the entire joint. By cleaning the residue, you eliminate the haze.
With Envirobond you can now install your paving stones without the worry of screwing it up, but still getting all of the benefits of a jointing material designed to stay in place.
