DIRECTIONS

A. REQUIREMENTS (BEFORE GETTING STARTED)

- The pavement surface and joints must be totally dry.
- The outdoor temperature must be greater than 5°C (41°F) for duration of 24hrs after installation.
- No rain should be forecasted within the next 24 hours of installation.
Optimal results: It should be sunny, dry, with temperatures greater than 20°C (68°F).

B. TESTING

Before using this product, always test the product on a small zone 1m2 (10 sq/ft) of your pavement making sure to follow the instructions carefully. Let dry for 24 hours. If you are satisfied with the results, proceed with the entire surface area.

C. INSTALLATION

1. Sweep DYNA® RJ Polymeric Jointing Sand evenly into the pavement joints using a push broom until the joints are filled completely.
2. Remove all sand residues from the top of the pavement, using a mechanical leaf blower.
3. Compact sand into pavement joints as prescribed by your paving stone manufacturer’s recommendations.
4. If necessary, after compaction, brush in a small amount of Polymeric Sand to ensure that the joints are filled to approximately 0.3 cm (1/8 inch) from the top edge of the pavers.
5. Blow off with the leaf blower all sand excess and dust residues from the top of the pavement making sure that the surface is perfectly free of all particles.

D. WATERING THE SAND JOINTS

Important: You will need to gradually water the Polymeric Sand 3 times. When doing so do not direct any water on the joints as it will displace the sand from the joints. Also, make sure not to over flood the placement joints as this will wash away the active ingredients from the polymeric sand, leading to poor results or failure.

i) First Wetting

1. Work in sections of about 100 m2 (1000 sq/ft).
2. Use a water hose equipped with a shower head working at medium debit. A good water debit is necessary but no pressure that could displace the sand from the joints.
3. Starting at the highest elevation of your surface, position the shower head at 1 foot from the surface and shower the stones in a sweeping movement from left to right.
Clean the stone surface rapidly while allowing the water to slowly migrate and channel into the joints. This first step will ensure that your stones are thoroughly free of all dust and will wet and stabilize the sand.
4. When finished watering your first section, you are then ready to proceed to the second wetting.

Notes: Focus on watering the stones not the pavement joints. By doing so, you will remove any fine particles that could have adhered to the pores of the substrate and keep the sand perfectly stable in the pavement joints. If pooling of water happens on top of the joints, proceed to wet another zone of your section.

ii) Second and Third Wettings

1. Change your sprayer. Now use a water hose equipped with a fine mist sprayer. If available, use a pressure washer to work faster.
2. Start again at the top of your surface and direct a fine mist of water in the air so that water gently drops down on the pavement surface and the joints. Do so until the sand joints and pavement surface have become moistened. Do not allow pooling of water on the sand joints.
3. Wait 5 to 10 minutes and repeat Step 2 one more time.

iii) Final Verification

10 minutes after the Third Wetting, verify if the Polymeric Sand is thoroughly moistened.
To do so, empty the sand joint in a few places using a key or a small screwdriver. Your sand should be moist all the way through. If you notice that water has not fully penetrated the joints, proceed with another fine mist application of water (as in step ii) until desired results are obtained.

iv) Drying Time

24 hours in dry warm weather.
