Sakrete PermaSand Polymer Jointing Sand is a mixture of sand and special ad-
ditives designed to fill the joints between pavers, bricks or natural stone.
FEATURES:
• Reduces weed growth
• Resists joint wash out
• Resists insect penetration
• Open to foot traffic in 24 hours
• Open to light vehicular traffic in 72 hours
• Helps lock pavers in place
USE FOR:
• Driveways
• Patios
• Walkways
• Any area with pavers
SIZE/COVERAGE*:
*Coverage varies considerably depending on size, shape and depth of paver.

RECOMMENDED DIMENSIONS:
• Joint width: Ideal minimum joint width is 1/4”. Although PermaSand will
harden in a 1/8” wide joint it is very difficult to get sand to compact the full
depth of a paver and difficult for water to penetrate sufficiently to harden the
PermaSand to the full depth.
• Maximum joint width: 1.5”
• PermaSand can be used in pavers with false joints that are 3/8” deep. However
special care must be taken while cleaning off excess dust from the pavers,
especially if a leaf blower is used. In addition the wetting procedure differs
slightly than when filling full depth joints. (See Installation section)
INSTALLATION:
1. Pavers must be installed on an adequate drainage base such as sand, stone
dust or Sakrete EZ Base
™
material.
2. For existing pavers, clean the joints between the pavers to the full depth of
the paver.
3. PermaSand should be applied when temperatures are above 40°F and no rain is
forecast within 24 hours.
4. Pavers must be completely dry. If pavers are damp or wet the polymer will
leave a stain on the surface.
5. Pour PermaSand onto the pavers. Using a broom sweep PermaSand into joints.
Material should be applied to within 1/8” of the top of the paver. If the pavers
have a beveled top do not fill the beveled section.
6. PermaSand must be placed in the full depth of the joint. Do not use sand or
other material to partially fill the joint.
7. To ensure that the dry PermaSand fills the entire joint it is necessary to compact
the material before wetting. If possible run a vibratory compactor over the
pavers. If this is not practical use a broom handle to tap on the pavers. The
PermaSand level with drop. Refill the joints and repeat the tamping process.
8. Using a leaf blower set on low speed hold the blower about waist high and blow
the excess dust from the top of the pavers. FAILURE TO ELMINATE ALL DUST
MAY RESULT IN STAINING. THIS IS ESPECIALLY CRITICAL WITH RED AND
TEXTURED PAVERS. If a leaf blower is not available, use a fine bristle brush to
remove all PermaSand from pavers.
9. THE PROCESS OF WATERING THE PERMASAND IS CRITICAL. INSUFFICENT
WATER WILL NOT ALLOW THE PAVER SET TO HARDEN THE FULL DEPTH OF THE
PAVER. TOO MUCH WATER WILL LEAD TO STAINING. Adjust the spray nozzle to
the “shower” setting. Spray using a back and forth motion. Look carefully at the
joints to see if the water is soaking in. Stop spraying and watch the joint sur-
face. If all water has soaked in keep spraying. Repeat until the joint will not
accept any more water. Do not allow water to splash PermaSand onto the
pavers. Do not add so much water that a white film (the polymer) will appear
and float out of the joint and onto the pavers. The wetting process should be
done without interruption. If too much time elapses the surface of the
PermaSand will set and prevent water from reaching the bottom of the paver. If
the surface of the joint is hard but the bottom doesn’t receive sufficient water
the PermaSand will eventually fail.
10. If the pavers have a false joint extra care must be taken when cleaning and
wetting to keep from dislodging the PermaSand. It may be necessary to adjust
the water to the “mist” setting to avoid displacing the PermaSand. It may not be
possible to use a leaf blower on pavers with a false joint.
