Sealing brick pavers is something that a do-it-yourselfer can do with good results. Sealing brick pavers such as a porch, patio, sidewalk, or driveway will have numerous benefits to the pavers and entire brick paver area.

Benefits of Sealing Pavers

  • Prevents sand erosion
  • Reduces weed growth
  • Deters ant colony activity
  • Blocks U.V. rays that cause fading
  • Reduces mold/mildew infiltration
  • Increases longevity of pavers
  • Enhances brick paver’s natural beauty

Before diving into brick paver sealing, be sure you plan the project during permitting weather. You will need a minimum of 2 dry days in a row to complete the project.

Cleaning Brick Pavers

As far as how to seal brick pavers, the first step is to wash the entire paver area with a pressure washer. You can use a brick or concrete cleaner to help break up dirt, grime, mold, and mildew. Be sure to blast all the old sand joints and weeds away. Always wear safety glasses to protect yourself from flying debris. Wash off all the debris and rinse well so no puddles are left on the bricks. After cleaning, you need at least 2 days of dry weather before continuing.

Re-Sanding Brick Joints

After the brick pavers have dried for 24 hours it is time to re-sand the joints before sealing. It is best to use polymeric sand that is designed for paver construction. Open a bag of sand and spread it around on the paver surface. Use a push broom to sweep the sand around filling in the cracks. Continue until all the joints are completely packed with sand, use a leaf blower to remove any excess sand that is left on the surface.

Sealing Brick Pavers

In new paver construction, the previous step may have been completed already and the pavers are now ready to be sealed. Remove any debris with a leaf blower or broom. Choose a high-quality brick paver sealer. There are numerous sealer finish choices from a matte finish to a “wet” look depending on your preference. Apply the brick paver sealer with a good contractor grade metal pump up sprayer. Note that an inexpensive plastic sprayer will not work.

Start at one end applying an even coat of paver sealer. Be sure to cover all the bricks and sand joints. It may be necessary to cut in edges with a brush. Once the surface is completely and evenly covered with sealer, rope off the area to keep people and animals off the sealed brick pavers for the next day or two while the sealer cures. Follow the cleanup instructions on the sealer container for cleaning up tools and sprayer.

Sealing your brick pavers every several years will keep them looking new and will give you many years of use and enjoyment.

    Just had contractor finish two week project replacing the original 70's concrete driveway to vacation house we bought last year with Flagstone pavers (a Fl-made paver) and having different type/color of same brand used to cover a bad acrylic finish chipping on the lanai patio…
    We were very careful no to walk or especially drive on driveway after they paid the pavers and before they sanded and sealed…
    we thought we chose a good contractor but the sanding for the driveway (with thick pavers) and sanding for the lanai with the thinner ones is very different…many gaps between pavers on the lanai and most on driveway are sanded all way to the top…since we didn't walk on either surface we didn't really notice the inconsistant work until after they sealed them and we were told we could walk on them after 4 or so hours…
    We have emailed the contractor Saturday but had no response due to weekend (I guess)…
    I have looked online for photos of good/bad examples of sanding w/o much luck…
    WHAT level of sand should be applied and brushed in — I read that 1/8 of inch lower than the bevel edge is standard on the Pavestone site…but on many of these pavers I think I can see to the sand spread over the concrete base…
    The cuts and the fact that they mortared the perimeter soldier course and poured a footing for any area not laid on concrete reflects attention to quality—
    but the fact that the sanding was done so indiscriminantly seems to indicate the opposite…
    The owner of the company never came to observe either of the projects but he has certification from the Paver Institute, is licenses, and bonded and has good BBB record…gives a 2 yr warranty for his installation…
    so we thought we made a wise choice…
    just want outside professional insight into what is a "quality" job…

      The sand level should be fairly even with no gaps and definitely nothing on top of the surface. We always leave our sand around 1/8\” to 1/4\” below the top edge.

    I bought some decorative flagstone pavers from Home depot and was wondering if i needed to use a cleaner on them ? Could i get away with just a good pressure wash and light brushing? Thx 🙂

    Should you mist the polymeric sand and let that dry, before applying the sealer?
