Why Choose Sika Block Paving Fix?

• Moisture-curing jointing compound.
• Designed for narrow 2–5mm joints.
• 3–4mm is the preferred joint-width range.
• Minimum joint depth of 25mm.
• Cures to a firm, stable joint.
• Helps resist weeds and insects.
• Weathers naturally alongside the paving.

How To Apply

• Make sure the paving is dry and free from loose dirt, oil, grease and debris.
• Check that joints are 2–5mm wide and at least 25mm deep.
• Do not pre-fill the joints with ordinary sand; the compound should fill the complete joint depth.
• Rake or stir the contents thoroughly and discard any hard lumps.
• Work in manageable sections and sweep the compound fully into the joints.
• Brush excess material from the paving surface before it begins to harden.
• Thoroughly soak the filled joints using a hose on spray or a watering can with a rose. Do not use a pressure washer for activation.
• Rinse away remaining material from the paving surface before curing begins.

After Application

The paved area can be walked on immediately after activation, although leaving it undisturbed while it dries can help achieve the best finish.

• Typical initial drying time is around 1–2 days.
• Full curing can take up to 28 days depending on weather and temperature.
• Wait at least 28 days before pressure washing the finished joints.
• When pressure washing after curing, keep the nozzle at least 10cm from the jointing material.

Before You Buy

• Do not apply below +5°C or when temperatures are expected to fall below this during drying.
• Avoid application when rain is imminent.
• The paving and joints should be well drained.
• Do not use where the joints will be permanently immersed in water.
• Test a small inconspicuous area first, as the natural aggregate colour can appear different beside different paving materials.
• Do not add extra sand to the product.

• Product FAQs

  Q: What joint widths can Sika Block Paving Fix be used for? Joint Width
  A: It is designed for narrow joints between approximately 2mm and 5mm wide. Joints around 3–4mm wide are the preferred range.
  Q: How deep do the paving joints need to be? Joint Depth
  A: The joints should be at least 25mm deep. Sika Block Paving Fix should fill the complete joint depth rather than being applied over ordinary jointing sand.
  Q: Can Sika Block Paving Fix be used on driveways? Driveway Use
  A: Yes. It is suitable for domestic block-paved driveways subject to light vehicle traffic, as well as paths, walkways and patio areas.
  Q: Does Sika Block Paving Fix help resist weeds? Weed Resistance
  A: Yes. Once cured, the firm joint helps resist weed growth and insects while providing a more stable finish than loose jointing sand.
  Q: Should the paving be wet before application? Surface Preparation
  A: No. The paving should be dry and clean during application. Once the joints are completely filled and excess material is removed, the filled joints are thoroughly soaked with water to activate the compound.
  Q: Can I use a pressure washer to activate it? Water Activation
  A: No. Use a hose set to spray or a watering can fitted with a rose. Do not use a pressure washer for activation.
  Q: How soon can the paving be walked on? Walk-On Time
  A: The finished surface can be walked on immediately after activation, although leaving it undisturbed while it dries can help achieve the best finish. Typical drying takes around 1–2 days.
  Q: How soon can I pressure wash after application? Pressure Washing
  A: Wait at least 28 days before pressure washing. After this period, keep the pressure-washer nozzle at least 10cm away from the jointing material.
