Preparation

Prior to installing projoint polysweep, ensure that pavement joints and surface are completely dry and clean. Additionally, ensure that there is no Rain forecasted for at least 12 hours after installation. If there is a possibility of rain shortly after installation, cover the area with a tarpaulin Sheet. Remove the tarpaulin as soon as the threat of rain is gone. Install Projoint polysweep when the average air temperature is above 5°c for a minimum of 48 hours after installation. Always wear appropriate ppe, including eyewear and a dust mask. Paving should be laid on a permeable bedding Mix, as Projoint polysweep cures when it dries out. Therefore, water/rain must have a route of escape. Check that joints are cleaned out to a minimum depth of 20mm, observing a minimum joint width of 1mm. If you are using polysweep on paving, ensure that it is firmly bedded and stable before filling joints.

ProJoint PolySweep Application

1: Distribute Polysweep evenly across the surface. Sweep sand into joints until full, being careful not to push the product over long distances on the Surface. After the joints are filled, sweep excess product from the surface.

2: For block pavers, run a vibrating plate compactor (wacker plate) over The blocks to allow the vibrations to consolidate sand particles into the joints and reduce voids. For paving slabs and setts, attach and use a rubber mat onto a wacker plate to vibrate sand particles into voids. Alternatively, using aa rubber mallet with a piece of wood will suffice. Sweep additional sand into the joints if necessary, so that the height of the sand is approximately 3mm below the pavement surface. (do not overfill joints.) remove Excess product from the surface. Repeat compaction.

3: After the joints are filled, sweep the surface with a soft brush and then use a leaf blower held on a slight angle but close to parallel to the surface to remove any excess sand/dust from the top of the surface. Without access to a leaf blower, we recommend brushing the surface multiple times to remove all excess sand/dust from the surface. Try to avoid removing any excess sand from joints.

4: Using a hose, gently mist the paving no greater than 45m2 at a time. Allow water to absorb for approximately 5 minutes and repeat the misting Process three to four times, each time gradually adding more volume of water. It is crucial that the water penetrates through the whole joint, not Just the top layer. The last watering should be sufficient to rinse off any residual material from the surface. In one of the joints, check the moisture depth in the sand with a screwdriver to see that it has penetrated through the whole joint. Replace sand and only apply additional misting if the water hasn’t penetrated fully.

5: Any residual surface water caught in the texture of the pavers or natural stone should be blown off the surface with a leaf blower or removed with a soft brush. 6: leave to cure. Projoint polysweep contains no portland cement. Cure times are dependent on temperature And humidity, but as a guide paving can accept traffic after 24 hours. Cool, damp and overcast conditions will decrease polyseep curing speed.

Caution

Do not apply too much water too fast. Allow water to absorb for approximately 5 minutes before repeating the misting process. Ensure the surface of the paving is clean prior to application. Projoint ultimate paving cleaner can be used to remove dirt, algae dust from the joints and pavers. Following cleaning, make sure the pavers and joints are completely dry prior to installing Projoint Polysweep. Do not apply this product to any wet or damp Surface because the polymeric sand will adhere to the surface and is difficult to remove. When pressure washing, keep the nozzle at least a foot away From the surface while at 40 degrees to the pavers, do not target the joints. Pressure washer surface cleaners are the most effective way of cleaning the pavers without harming the joints. Projoint polysweep has a low level of permeability, therefore, pavers must have adequate drainage and/or falls.
