Clay Pavers - Untreated

For the thinner and more absorbent type of tile that is also called "pavers", see our page on tiles.

Concrete pavers are made with higher compression and longer vibration than a regular concrete block.  Clay pavers are fired at higher temperatures than a regular brick.  The end result for both types is a much stronger and more durable unit of lower end absorption.

There is no need for confusion or problems brought about by misidentification of a surface type, yet it happens all too often. If you would like to see why this is the case and how to properly identify a surfacing material ..... Click here

If you are concerned about doing it yourself - consider that the satisfaction of a project is directly related to your knowledge of what needs to be done and how. Who actually does the work is less important. We estimate that 25% of the usage of Aldon products is by "do it yourself" homeowners and we know they are happy because we hear from them.

MATERIAL DESCRIPTION - With Identifying Characteristics

Typical absorption range = very low to low

Testing your surfacing for absorption rate

Testing for acid sensitivity

  • Over 2 inches high - usually sand joints, but can be mortared in place.
  • Layed in sand or finely crushed rock bedding.
       (Lesser heights are usually layed on a concrete bed and are discussed on other pages as tile pavers or thin-brick)
  • Many different shapes - from the typical brick rectangle to exotic interlocking patterns.
  • Available in many colors.
  • Can have vertical rib projections that provide automatic joint spacing.
  • Concrete pavers are denser and stronger than concrete wall brick due to stronger mix design and longer compaction cycles.
  • Clay pavers are denser and stronger than standard clay brick due to more kiln time at higher temperatures.
  • Wall brick of clay or concrete are routinely used for residential patios. See those pages if that is what you are using. The correct sealer will increase the strength and durability of a wall brick.

  • Extremely tough and durable. Used in Europe for decades in high volume commercial parking areas.
  • Sand joints and bed allow for easy removal for design modifications or subsurface repair work.
  • The sand bed and joint method saves money over concrete bed and joint.
  • Great variety of colors and shapes allow for a wide spectrum of creative design.
  • Also available in a "tumbled" type that is more antiqued and has rounded edges.
CONSIDERATIONS      (All Are Preventable!)

(Click links for Aldon's solutions to these issues!)

  • To clean the following - click here
    • Efflorescence (subsurface originating white powdery stains).
    • Scuffing from palletized transportation and vibrator plate installation.
    • Drips, footprints, and clinging paste from wet saw cutting.
    • White smears can be from non-Aldon "sand stabilizing" polymer additives that wash out of the sand and across the face of the pavers. This is handled differently than efflorescence as explained at the bottom of the page linked above.
  • Loss of joint sand from wind and water action can cause movement problems for the pavement mass. Tracking sand into buildings can damage floors. To prevent these things by "stabilizing" joint sand - click here to see an easier and less expensive methods than adding a glue type product to the sand mixture.
  • Colors can "fade". Actually the iron oxide pigments used in concrete products do not fade. Nor do the colored clays in clay products. The appearance of fading is actually from light efflorescence and can be stopped by sealing with the appropriate Aldon sealer.
  • All concrete products are subject to damage from acids. However, the appropriate Aldon sealer prevents this.
  • Retard weed growth? Here is the theory, but we do not have any actual history on the issue. Stabilizing the sand joints (see above) with the sealer should logically do two things that would retard weed or grass growth. The sealed sand would not trap and mix with dirt that contains the nutrients needed to sustain growth, and weed seeds would have little ability to establish a root structure in a more "solidified" mass of sand. To accomplish this you need one of the penetrating sealers classified in the as "densifying".

Following are recommendations for products you may need (in sequence of use ) for whichever of the categories applies to you. Please review each and mark your printed worksheet accordingly. Lifeguard can be used after sealing, but is generally not needed for driveway pavers. The cleaning products "Maintain" and "Dust Whiz" are for interior applications. "Insta-Clean" is used for interior and exterior cleaning, including driveway cleanup before and after sealing.

Regarding The Sealer Results Shown Below


An Aldon sealer does far more than just bead water and look pretty! To see what that is click here.

  • Your results may vary somewhat from these pictures due to variations in computer display and the surface materials themselves. Nevertheless, you will be able to see the differences well enough to make good choices.
  • Different areas of the same piece are used as much as possible to minimize raw material variations.
  • Of all the sealers Aldon manufactures, the ones shown are recommended as best suited to this surface type.
  • (Important: If your project has had any sealer applied in the past, it must be evaluated differently. To see why, Click here!)
  • Renewal of a glossy finish: sealer applications can be made hours or years later, but do not apply thin layer upon thin layer. Apply a sufficient quantity to insure below surface penetration & bonding. Or, test spray on of lacquer thinner as an alternative to slightly melt and reform the surface and not build too much gloss or sealer "layering". Sealer layering can result in poor bonding between layers and that can cause graying (peeling).


Unsealed Paver
Concrete paver - unsealed
"Same Day Sealer"
Water Based - Penetrating Type

(On the "unsealed" paver above)

  • One Application - Fully Sealed
  • No Color Change or Gloss
  • To illustrate that this paver is sealed - there were water drops placed at all four corners. The bottom left corner was not sealed and immediately absorbed.


"S-B-S Sealer"

Solvent Based - Penetrating Type

Very Little or No Gloss Creation

Some Color Enhancement

Excellent Penetration and Bonding Into Dense Driveway Pavers

  • (These two pictures are the same half of a tan paver - from a different manufacturer than the paver used for "Same Day Sealer" above)

      Top Picture:

    • One Application - Fully Sealed
    • Color Enhanced - Very Little Gloss
    • (Note water drop to show it is sealed)

      Bottom Picture:

    • Same Piece - Second Application to Increase Gloss
    • Color Enhanced - A Bit More Gloss


  • very low or no gloss
  • color enhancing
  • joint sand stabilizing
  • easy applying and forgiving of overlap
The S-B-S label has a special section in the application instructions devoted to interlocking pavers.

See below for "Penetrating Paver Sealer" that is formulated for the unique characteristics of interlocking concrete or clay driveway pavers.



"Penetrating Paver Sealer"

Solvent Based - Penetrating Type

Low Gloss - Nice Color Enhancement

Excellent Penetration and Bonding Into Dense Driveway Pavers

Stabilizes Sand Joints

  • One Application
  • High Gloss
  • Color Enhanced

(These two pictures are the other half of the same paver shown above for "S-B-S Sealer")

    Top Picture:
  • One Application - Fully Sealed
  • Color Enhanced - Medium Gloss Level
    Bottom Picture:
  • Same Piece - Second Application to Increase Gloss
  • Color Enhanced - High Gloss Level
Note 1: a low gloss finish is typically better for the high abuse level of driveways.
Note 2: Concrete pavers are generally very strong and very dense. The density creates a low absorption rate.
