Application Summary
Quick-reference checklist of key requirements before and during application
-
1Compact as normal
Complete final compaction of the paving with a plate compactor as normal. Ensure the surface and jointing sand are thoroughly dry and free from dirt before proceeding.
-
2Sweep thoroughly to remove surplus sand
Following final compaction, sweep the area thoroughly to remove surplus sand. Ensure the jointing sand has been fully removed from the chamfer. Ensure both sand and paver are completely dry.
-
3Apply by watering can with rose (1 litre per 2 m²)
Resiblock '22' is not much thicker than water and is easily applied using a watering can with a rose attached. Fill your watering can, then pour out 1 litre evenly over 2 m² — a manageable amount to squeegee. Ensure the rose is fitted to the watering can.
-
4Squeegee off the surface, working towards you
Having applied Resiblock '22' to the pavers, squeegee off the surface starting at the top and always working towards you. Pull the product off the surface — it will pool in the chamfers/joints and be absorbed by the kiln-dried jointing sand.
-
5Clean all tools immediately with RESICLEAN
All uncured sealant spillages/splashes and tools must be cleaned immediately using RESICLEAN. Do not use other solvents.
Full Application Instructions
Complete step-by-step guidance from surface preparation through to curing
Coverage is 1.0–2.5 m² per litre depending on joint width and paver porosity. Accurate application rates are essential to ensure full joint stabilisation — for example, 100 x 200mm CBP at 2 m² per litre. For other dimensions or types of paving, contact Resiblock's Technical Department on 01268 273344. Two coats are recommended for concrete block paving. Clay pavers require one coat only.
Make sure the surface and jointing sand are thoroughly dry and free from dirt. Application to poorly prepared pavers, particularly regarding dampness, can result in inadequate joint penetration or paver adhesion, and in exceptional circumstances discolouration and disbonding. Ensure paving is thoroughly swept and that no jointing sand remains in the chamfers of the pavers.
- Watering can with rose attached (e.g. 5 litre gauging pot)
- RESIBLOCK SQUEEGEE
- Plate compactor
- Stiff broom for sweeping
- RESICLEAN for tool cleaning
-
1Apply first coat by watering can with rose
Apply to the surface using a watering can with the rose attached. For standard 100 x 200mm CBP, pour out 1 litre evenly over 2 m² — a manageable amount to squeegee. Ensure even coverage across the marked area.
-
2Squeegee off, working towards you
Squeegee off the surface starting at the top and always working towards you. Remove all surplus with the RESIBLOCK SQUEEGEE — the product will pool in the chamfers/joints and be absorbed by the kiln-dried jointing sand.
-
3Apply second coat once first is touch dry
Two coats are recommended for concrete block paving. Apply the second coat once the first coat is touch dry, following the same watering can and squeegee method. For further advice on coat systems, contact Resiblock's Technical Department.
In certain applications — such as airfields, equestrian facilities and wheelchair access points — and particularly when used as a two-coat system, additional anti-slip qualities may be required. Contact Resiblock's Technical Department for guidance on achieving an anti-slip surface.
Rapid initial cure takes place depending on ambient temperature, humidity and block porosity — 1–3 hours can be expected. Once the surface is dry, the paved area can be subjected to foot or light traffic, but full chemical cure must be allowed to take place (24 hours) before the surface is subjected to full traffic or vehicle use. Avoid walking on the sealed area until the face of the paver is dry to the touch.
Resiblock '22' cures rapidly on exposure to atmospheric moisture. Clean all uncured sealant spillages, splashes and tools immediately using RESICLEAN. Do not use other solvents.

Specification Clause
For engineers & specifiers — sealing pavers specification
The sealer shall be a liquid SPPU (Specialist Pre-Polymer Urethane) moisture curable (or triggered) aromatic/aliphatic in a hydrocarbon solvent, having the following minimum properties:
- Surface curing time not to exceed 24 hours (touch dry approximately 2 hours at 15°C).
- Does not adversely affect slip/skid values (independent test report may be required).
- Be highly resistant to oils, diesel, petrol and de-icing fluids.
- Must not adversely change the colour of the paving.
- Elongation at break of film not less than 350% (ASTM D2370).
- Withstand temperatures in excess of 200°C.
- Prevent jointing sand erosion by a direct jet of water at a pressure no less than 200 bar (1500 p.s.i.), with the lance 150mm from the surface.
- Withstand vacuum sweeper suction (minimum velocity 60 m/sec) 24 hours after installation.
- The sealer must be capable of penetrating the joints to a minimum depth of 20mm and shall form a flexible elastomeric water and fuel resistant bond.
The material will need to withstand a minimum of 10,000,000 cumulative standard axles without distress or deformation to the stabilised sand. This should be demonstrated either by proven track record for a period of no less than 5 years. The sealer shall have a proven safety and performance record of use on similar pavements to that used on this project.
