Accurate application rates are critical for full joint stabilisation. Ensure sufficient material is purchased before starting — if more is needed mid-project and an overlap occurs after 24 hours, disbonding and patchiness may result.
At-a-Glance Checklist
  1. 1
    Purchase adequate material

    25 litres covers approximately 50 m² at 2 coats. Ensure you have enough before starting — do not order additional material to complete an area mid-project.

  2. 2
    Confirm surface is thoroughly dry and clean

    Surface and jointing sand must be completely dry and free from dirt. To check: scrape jointing sand to a depth of 5–10mm — if the sand is dry, so are the blocks.

  3. 3
    Check weather conditions

    Do not apply if rain is forecast within 12 hours, or in temperatures below 3°C or above 30°C.

  4. 4
    Sweep paving thoroughly

    Ensure paving is thoroughly swept and that no jointing sand remains in the chamfers of the blocks.

  5. 5
    Apply 1st coat at 3 m²/litre, then 2nd coat at 6 m²/litre

    Apply edges with a paintbrush and the main area with a RESI-ROLLER. Allow a minimum of 3 hours and maximum of 24 hours between coats. Apply the second coat at right angles to the first.

  6. 6
    Restrict access during cure

    No foot traffic for 3 hours after application. No vehicles for 24 hours. Only coat an area you can complete in a single day — if a break is needed, cut in to a sand joint with a brush to avoid a striped effect.

  7. 7
    Clean all tools immediately with RESICLEAN

    All uncured sealant and tools must be cleaned immediately using RESICLEAN. Do not use other solvents. Resiblock Superior cures rapidly on exposure to atmospheric moisture and cannot be removed once cured.

Coverage

Resiblock Superior is a 2-coat system. Coverage can vary depending on absorbency levels. On new concrete pavers, an average of 3 m² per litre can be expected on the first coat and 6 m² per litre on the second. Coverage can be reduced by as much as 25% on old, worn or high-porosity pavers. A similar increased coverage can be expected on specialist designed pavers (e.g. Marley Victorian Knott, Marshalls Tegula).

The surface must be clean and free from oil, algae, dust and lime bloom. Substrate must be dry — application to damp or wet surfaces can result in poor adhesion and discolouration. Jointing sand containing moisture can prevent bonding and stabilisation of joints. Do not use if rainfall is forecast within 12 hours.

Trade tip: To check if paving is perfectly dry, scrape out the jointing sand to a depth of 5–10mm. If the sand is dry, so are the blocks.

All traces of kiln-dried sand on the face of the blocks must be removed by broom or garden leaf blower (set to 'blow'). Ensure sand does not protrude from the base of the chamfers. If pavers or joints have been previously treated with any other stabiliser or sealer, contact Resiblock's Technical Department prior to application.

Preparation — New Work

Carefully measure the area in square metres and allow a minimum of 5 litres for every 10 m². On new work, a thorough sweep with a stiff broom is usually sufficient. If the surface has become partially weathered or contaminated, wire-brush to remove all debris. For large areas, pressure cleaning may be more effective.

Ensure joints are well filled to the bottom of the chamfers with clean, compacted kiln-dried sand. Ideally, at the time of installation joints should not be filled with kiln-dried sand — this allows filling and compaction on the day of sealing, ensuring the sand is completely dry for optimum absorption.

Preparation — Old/Refurbished Work

Pressure clean to remove all algae, lichen, weeds and most of the top layer of jointing sand. This will also remove food, drink stains and surface grime. If pavers are badly stained with engine oil, replacement should be considered. However, treating with Resiblock O.R. before pressure cleaning should remove at least 75% of the stain; once Resiblock Superior is applied, it will darken the pavers, camouflaging any remaining stain.

Once dry, re-fill joints using kiln-dried sand and sweep in using a soft broom. Remove all surplus sand.

Washing or pressure cleaning can cause substrate saturation and reactivate efflorescence. Allow at least two weeks between cleaning and applying Resiblock Superior to allow the area to dry out fully.
Equipment Required
Method of Application — First Coat
  1. 1
    Do not dilute. Start at the perimeter

    Do not dilute Resiblock Superior. Begin by coating the perimeter of the paved area with a 10cm paintbrush, working the product well into the 'cuts' and edges.

  2. 2
    Roll in bands, left to right, keeping the wet edge going

    Using the RESI-ROLLER, start top-left and work away from the building. Move left to right in bands approximately 1m deep. Walk back to the left to begin the next band. This keeps the wet edge active. Failure to do this — particularly in hot weather — may cause 'zebra' striping.

  3. 3
    Apply evenly at 3 m²/litre — no misses, no puddles

    Work material well into untreated joints, ensuring sufficient product penetrates the jointing sand. Apply a liberal, uniform coat without misses or puddles. Do not attempt to build in one coat — excess material, particularly on light-coloured (buff/grey) pavers, may cause dark yellow/brown discolouration. Ensure accurate spread rate of 3 m²/litre.

If Resiblock Superior is applied too thickly, the substrate is damp, or it is excessively cold, bubbling may occur giving the appearance of a white/milky residue. Solvents released during cure normally permeate through the sealer, but not if over-applied.
Trade tip: To avoid tea-break lines, stop and start at a specific sand joint by cutting in with the 10cm brush. If you need to walk on a still-wet area, use an old pair of golf shoes.
Method of Application — Second Coat
  1. 1
    Wait — minimum 3 hours, maximum 24 hours

    Apply both coats the same day if possible. Wait until the first coat is completely dry. Minimum time between coats: 3 hours at 20°C. Maximum: 24 hours. This limit must be strictly adhered to — exceeding it may cause disbonding and patchiness of the second coat.

  2. 2
    Apply second coat at right angles to the first

    Apply the second coat at right angles to the first, ensuring the entire area is uniformly and methodically covered. Ensure accurate spread rate of 6 m²/litre.

Kerbs: Despite being a smoother texture, kerbing systems are very porous and will require a third coat. The same coverage and application time constraints apply.
Anti-Slip Surfaces

In most cases Resiblock Superior should not adversely affect the grip characteristics of pavers. However, on higher density pavers, gradients, or around fuel pumps (S.S.F.s), additional anti-slip qualities may be required — test on an inconspicuous area first.

To achieve an anti-slip surface: dust dry jointing sand onto the first coat while it is still wet using the broadcast method. When dry, apply the second coat — this 'sandwiches' the aggregate between the two coats. Resiblock Superior must not be used around swimming pools.

Curing Period
Touch Dry
~1 Hour
Foot Traffic
3–6 Hours (20°C)
Vehicle Traffic
1–2 Days
During the initial drying period it is essential to keep children and pets away from the installation.
Efflorescence (Lime Bloom)

Efflorescence (also known as lime bloom or laitence) can occasionally appear as white powdery patches before application, or creamish patches after. Steps to reduce the risk:

  1. Apply after a dry spell of at least 48 hours. Verify the entire paved area is dry by checking the sand joints.
  2. Allow 8 weeks after paver installation before applying. Allow at least 2 weeks after washing/pressure cleaning of old installations.
  3. If lime bloom appears before sealing, clean with Resiblock E.R. (efflorescence remover).
  4. If in doubt, contact the Resiblock technical department before proceeding.
Efflorescence is a naturally occurring phenomenon caused by the manufacture of the blocks. It is neither caused nor exacerbated by the application of Resiblock Superior.
Maintenance
Issue Recommended Action
Oil, diesel or grease spills Apply mild detergent with a soft scrubbing brush and rinse away. Stubborn stains: use Resiblock O.R. first, then pressure clean.
Algae / lichen regrowth Regular washing and gentle scrubbing. For stubborn growth, use a pressure washer.
Weed / grass tufts Pull weeds by hand and apply a small amount of Resiblock Superior into the joint by brush. 0.25 litre cans available free of charge.
General surface grime Seasonal cleaning with a pressure cleaner is recommended.
Worn appearance / re-coating Contact Resiblock Customer Services for technical information on the re-coating process.
Cleaning Tools & Equipment

Resiblock Superior cures rapidly when exposed to atmospheric moisture, forming a film that can only be removed with great difficulty. Clean all equipment immediately using RESICLEAN. Do not use other solvents as unknown synergistic reactions may occur. Wash with water and detergent afterwards.

Do not return unused material to original containers. Do not reseal or store partly used kegs — Carbon Dioxide may generate and put the drum under pressure, which might rupture it. Any remaining traces of Resiblock Superior in used drums must be cured by leaving containers open and, in dry conditions, adding water to each container.
Health & Safety
PVC gloves & protective clothing
Face shield must be worn
Barrier cream on exposed skin
No smoking or naked flames
Ensure good ventilation
Mask essential near surface or internally (Sabre or Martindale recommended)
Do not apply near foodstuffs
Always refer to current Safety Data Sheets
Resiblock Superior is FLAMMABLE. Flash point 45°C. No smoking or naked flames to be allowed. Where public access is permitted, erect NO SMOKING signs and site fire extinguishers. Do not clean hands with RESICLEAN — solvents tend to de-fat skin and can cause dermatological problems.

Technical Datasheet

Product description, features, performance data and storage information

Resiblock Superior is a urethane based low viscosity prepolymer in hydrocarbon solvents. Its function is to bond the jointing sand and seal the surface of concrete block paving. Penetration comes about by solvent evaporation; polymerisation is created by atmospheric and residual moisture effecting the cure. The resulting effect is an in-situ bond and stabilisation of the pavement that retains its normal flexural properties. Manufactured under BS 5750 / ISO 9002.
