Can you seal paver sand?
You can protect the joint sand from washing out by sealing the paver surface. Sealing restores the beauty of your pavers. The paver sealer also serves as glue between the joint sand particles hence holding them together, and preventing the sand from being washed away when it rains or during pressure washing.
Is silica sand polymeric?
Polymeric sand is a fine sand that is combined with additives that form a binding agent when exposed to water. Silica is such as an additive and is often used to help lock the fine sand particles together.
Can you put sand in sealer?
Add 10 to 15 pounds of sand (2 to 3 pounds per gallon) to the sealer. Mix it in thoroughly, using a paint stick or metal rod. Begin resealing the driveway. Stir the mixture occasionally to keep the sand properly mixed.
When can I seal polymeric sand?
Traditionally, concrete paver manufacturers have recommended waiting at least 90 days after polymeric sand installation to apply a protective sealant to a paver surface. Nowadays, a 30 day delay is sufficient to allow the evaporation of any remaining natural efflorescence contained in the pavers.
Is silica sand good for pavers?
Silica sand between pavers creates friction that locks everything together. Sand helps mitigate weed growth, as well as prevent moisture from seeping underneath the pavers. Silica sand is easy to apply between concrete pavers and allows for a smooth surface between paving joints.
Is paver sand the same as silica sand?
Dry Pavior Sand Also known as ‘Paver’ or ‘Block Filling’ sand, this kiln-dried silica sand is commonly used to fill joints between paving slabs, enabling a close and tight bond. It actually contains silicon dioxide, hence the name.
What is sand seal?
A sand seal is a sprayed application of asphalt emulsion followed by a covering of clean sand or fine aggregate (figure 4). Excess sand is removed from the road surface after rolling. Sand seals enrich weathered pavements and fills fine cracks in the pavement surface.

Do you need to seal the joint sand?
So it would make sense that maintaining the joint sand would keep the structure intact and increase its longevity. To maintain paver joint sand and keep it safe from erosion, you can seal it. Once the pavers are in place and joint sand has been installed, a paver sealer can be applied to the entire surface.
What kind of sand to use in paver sealer?
After investing in a new paver patio or driveway we recommend joint stabilizing silica sand and sealer. This is a combination of using joint stabilizing silica sand and a liquid product that protects and penetrates both the paver and the sand in the joint as well. We prefer joint stabilizing paver sealer over Polymeric sand for several reasons.
Can you use sand as a sealer on concrete?
Using sand in a sealer for concrete does NOT work. The sand stays on top of the surface. Plus when you add it to the sealant, it sinks to the bottom regardless how much you stir it. So, in other words, it isn’t a viable option. Just to clarify, don’t add sand to a sealer when it’s still in the sprayer.
