Sealing Joint Sand From Erosion

Pavers are a great addition to any property. They are diverse in design and make for a durable surface. When pavers are installed correctly, they are laid on a compact bed of sand. Sand is also used to create joints between each paver. Joint sand is usually polymeric sand that consists mostly of fine sand and silica. This creates a binding agent that solidifies the sand particles together, which helps lock all the pavers together.

Harsh elements like wind and rain can break down the joint sand and cause it to erode over time. This can jeopardize the whole paver structure, as the joint sand is an important part of the system. Eroding joint sand is the main cause of most paver system failures. So it would make sense that maintaining the joint sand would keep the structure in tact 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. A good paver sealer will penetrate the joint sand and help to solidify it. This locks out moisture and blocks the wind to eliminate erosion. Sealing the pavers and joints can also enhance the beauty of the surface and give it a more appealing look.

Reasons to Seal Paver Jointing Sand

  • Structural integrity of paver designs
  • Reduces sand washout from rain
  • Reduces grass and moss
  • Reduces insects

Best Sealers For Stabilizing Sand Joints

  • SuperSeal25, SuperSeal30, SuperSeal Matte
  • Surebond SB-1300, Surebond SB-7000, and Surebond SB-8700
  • Masonry Saver(Defy) Paver Sealer

Sealing joint sand from erosion is a great way to protect your paver investment. Regular maintenance will still be required as the sealer wears off. But simply washing the pavers, installing new sand, and resealing is all that is needed to maintain a durable paver structure. Do not let wind and rain ruin your paver areas. Use a quality paver sealer to protect from joint sand erosion and increase the life of your pavers.

    I just had a paver pathway installed, and the polymeric sand is softening when it gets wet (after what should have been the proper cure or setup time). What joint stabilizer / sealer would be good to apply to get a matt or semi-gloss finish on the pathway and firm up the joints

    Try the SuperSeal Matte. One coat and about 12 gallons for 1200 sq. feet.

    Job just completed. New pool coping and remodel pavers up to the outside edge of the pool cage. My wife would prefer matt with a wet look finish. a) What product would harden the sand while giving us top-notch surface protection? b) The square footage is approx 1200sq ft. How many gallons will be required and how many coats does your company recommend? Thanks much

    The SB-6000 does not seal or harden sand. You could try the SB-8700 which seals sand and gives a wet look.

    I just used your SB-6000 and the patio looks GREAT. I actually just getting ready to order another 5 gallons to seal my paver walkway's. Is SB-6000 good enough for sealing paver sand or do I need to use something else that I can apply after the SB-6000?
