GATOR SAND XP
Very firm between the paver joints
DESCRIPTION OF GATOR SAND XP- XTRA Performance Polymeric Sand
Gator XP Sand is a unique mixture of polymer binders and calibrated sand available in Beige, Slate Grey and Ivory. The installation of Gator XP Sand Bond is almost identical to using regular paver joint sand, except for the application of water. Once Gator XP Sand Bond sets, it becomes very firm and locks between the paver joints. This firm bond maintains pavers securely in place, being equally effective on both horizontal and sloped surfaces.
- Sloping areas
- Pool surroundings
- High traffic areas
- Parking lots
- Can be used for paver joints up to a maximum of 3.5cm.
- Starts to set as soon as water is sprayed. Fast setting.
- Sets at above freezing temperature 0°C
- Can be applied even if rain is expected (minimum 1 hour after sand installation).
- Does not haze paving stones.
- Intact pallets can be stored outside.
- Helps prevent weed sprouting
- Helps prevent damages caused by insects
- Helps prevent erosion due to climatic conditions, such as wind, rain and freezing.
- Xtra Bonding: High polymer content.
- Xtra Durability: Good for high traffic areas & commercial job applications.
- Xtra Resistant: For areas where we have excess water or very steep slopes.
APPLICATION OF GATOR SAND XP for a NEW PAVER JOB
Use a concrete sand as your bedding sand to do the final levelling. Install the concrete pavers or slabs.
After the paver surface has been installed, it should be compacted using a vibrating-plate compactor, with a 2.200kg (22 kN) centrifugal compaction force. We recommend using a mat fastened to the vibrating plate when compacting the pavers in order to avoid damaging them. The whole paver surface area should be compacted at least twice so that all pavers seat firmly into the bedding sand.
Make sure the paver’s side and top surfaces are dry before applying the polymeric sand. Spread GATOR SUPER SAND BOND over the pavers, then use a hard-bristle brush to sweep the sand into the joints and fill them completely. Run a vibrating plate-compactor over the pavers in several directions to compact the sand inside the joints (this action is not appropriate for slabs). Repeat this triple step (spreading the sand, sweeping it into the joints, then compacting) at least twice.If a vibrating-plate compactor cannot be used, stamp the stones with a rubber mallet and make sure the GATOR SUPER SAND BOND is densely packed in the joints
Using a fine-bristle broom, remove any excess sand from paver surfaces. Make sure the finished sand level is at least 3mm lower than the chamfer of the pavers. Using a leaf blower, remove any sand residue from paved surfaces. Depending on the physical layout, it may be more appropriate to remove residue by using a vacuum unit.
At a height of 1.2m, use a water gun connected to a hose to direct a fine mist (water gun setting: “mist” or equivalent) of water on a specific paved area for 10 to 15 seconds. Wait 3 to 4 minutes (not longer). Proceed to STEP 5.
From a height of 60cm, aim the water mist directly at the paver surface. Mist and rinse simultaneously so as to eliminate any GATOR XP SAND residue left on the pavers. Any GATOR XP SAND residue should go directly into the paver joints. Wait 3 to 4 minutes (not longer). Proceed to STEP 6.
From a height of 60cm aim the water mist again directly at the paver surface. Again, mist and rinse simultaneously so as to eliminate any GATOR XP SAND residue left on the pavers. The GATOR XP SAND residue should go directly into the paver joints. However, stop misting (ALERT) when you see a minimal amount of water retention on the paver joints.
Use a leaf blower to remove any excess surface water lying on paver pores and crevices. This blowing action isnecessary to help remove any remaining GATOR XP SAND residue that was left on paver surfaces.
The water used in steps 4, 5 & 6 will activate a bonding action as well as condense GATOR XP SAND in the joints. Too much water will undo the dense compaction obtained during step 2 and reduce the final performance of GATOR XP SAND. If steps 4 to 7 are not done properly, a white haze may appear on paver surfaces after installation. This is due to excess GATOR XP SAND residue left on paver surfaces. This haze will dissipate over time. It can also be removed by using a concrete efflorescence cleaner.
METHOD for applying Gator XP Sand as part of an EXISTING PAVER JOB:
- Using a pressure washer, remove all the existing joint filling material from the top of the pavers to the bottom. Be careful to not disturb the bedding sand under the pavers.
- Follow step 2A to 7 of NEW PAVER JOB instructions.
Do not apply on wet or damp surfaces, since bonding action will cause GATOR XP SAND BOND to stick on the surface instead of properly sliding into the joints. Do not use if rain is expected within 1 hour. Avoid excessive watering or flooding of paved surfaces. When installing pavers around an underground pool, a slope of 1/8 inch per linear foot away from the pool is mandatory. All paver surfaces must present a drainage slope for GATOR XP SAND BOND to work optimally. For the pool coping units, it is mandatory to use mortar in the joints. For the rest of the paver installation around the pool, you can use GATOR XP SAND BOND. Do not sweep GATOR XP SAND BOND over asphalt.
- The GATOR XP SAND BOND is ideal for narrow or large joints up to a maximum of 3.5cm.
- Never use GATOR XP SAND BOND when pavers are installed on a concrete slab.
- Do not sweep over asphalt.
Gator XP Sand is recommended for a variety of uses, including pool sides, patios, foot paths, driveways, parking spaces, pavements etc. The concrete pavers must be installed on a drainage base system composed of 2 layers. The upper layer can have a maximum of 2.5 cm of bedding sand. The lower layer must have a minimum of 12.5 cm of crushed stone, compacted at 95% of the Proctor density.
