Sanding Before Sealing

To Sand or not to sand?

There’s a lot of discussion in the industry about whether sanding should be done before sealing. Some think it’s needed and others feel it’s not necessary. While this isn’t our area of expertise we prefer to share the opinion of the experts on this matter.

The Experts

The Interlocking Concrete Pavement Institute (ICPI) is a non-profit trade association dedicated to the advancement of the interlocking concrete pavement (ICP) industry. ICPI has recently merged with and is soon to become the Concrete Masonry & Hardscapes Association (CMHA).

ICPI says yes, you should sand your pavers before sealing. Sanding the joints between the pavers helps to fill in any gaps and create a smooth, even surface. This will help the sealer to adhere more effectively and provide better protection for your pavers. Recommending levels of sanding prior to sealing can be seen below in image.

• There are a few reasons why it is important to sand before sealing pavers.
  • To fill in the cracks and gaps between the pavers. This helps to create a smooth, even surface that is easier to walk on and less likely to collect dirt and debris.
  • To prevent weeds and grass from growing in the cracks, the sand helps to block out sunlight and moisture, which are essential for plant growth.
  • Sanding will help to prevent household pests from having easy access to the area.

  Steps to Sanding and Sealing Success

  Here are the steps on how to sand pavers to ICPI standards:

  • Remove any debris from the surface of the pavers. After washing, use a broom or leaf blower to remove any dirt, leaves, or other debris from the surface of the pavers.
  • Clean the joints between the pavers. Use a stiff-bristled brush to clean the joints between the pavers. This will remove any dirt, debris, or weeds that may be growing in the joints.
  • Apply the sand. Use a broom to apply the sand to the joints between the pavers. Be sure to fill in all of the gaps between the pavers. You can also wet the sand to help the sand to compact into the area.
  • Allow the sand to dry. Allow the sand to dry completely before walking on it. This will help the sand to set and prevent it from tracking into your home.
  • Apply Sealer. Follow the manufacturer’s instructions for the type of sealer you are using.
