Block paving sealers

You will find information on Acrylic and Polyurethane sealants on this page.

Below you will find information on Block paving Sealants available from different manufacturers. The leading maufacturer of Polyurethane sealants is Resiblock. We have given two examples of the products below. These are the two common strengths that we tend to apply:

Resiblock

DESCRIPTION

RESIBLOCK '22' matt paving sealant is a urethane based low viscosity prepolymer in Hydrocarbon solvents. Its function is to penetrate jointing sand and bind the particles together and to the sides of the pavers. RESIBLOCK '22's penetration comes about by solvent evaporation, and polymerisation is created by the 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. RESIBLOCK '22' matt paving sealant is manufactured under the jurisdiction of ISO 9001/2.

BENEFITS

  • Prevent sand being removed by vacuum sweepers.
  • Prevent loss of sand in areas liable to flood
  • Prevent sand loss by propeller wash and jet blast.
  • Prevent blocks from spalling, cracking and settling by heavy traffic after use.
  • Greatly exceeds ASTM D 2370 (elongation test).
  • Prevent serious damage to bedding by freeze/thaw cycle.
  • Retain characteristic flexibility of paving (sealers are Elastomeric).
  • Strengthen pavement.
  • Unaffected by commercial de-icing salts.
  • Retain jointing sand to provide block interlock.
  • Suitable for areas that have severely channelised traffic.
  • Sealing of joints prevents cont
  • amination of groundwater by Hydrocarbons.
  • Unaffected by water or ice.
  • Reduce paver loosening and creep.
  • Reduce dusting of blocks.
  • Has the property of elasticity after polymerisation.
  • Maintains the sand in the joints even under high velocity water flows.
  • Prevents the ingress of chloride ions from de-icing salts
  • Will act as a surface sealant on most types of wet-cast paving.
  • Rapid drying characteristics, ensures rapid use of the facility.
  • Suitable for use on both concrete and clay pavers.
  • Allows easy removal of pavers for access to services.
  • Approved for use on petrol station forecourts and airfields.

DESCRIPTION

RESIBLOCK SUPERIOR wet-look paving sealant 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. Its penetration comes about by solvent evaporation, and polymerisation is created by the 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. RESIBLOCK SUPERIOR paving sealant is manufactured under the jurisdiction of ISO 9001/2.

BENEFITS

  • Wet-look surface.
  • Will not chip or peel.
  • Stop blocks becoming stained by engine/fuel oil.
  • Eliminate weed and grass growth in the sand joints.
  • Prevent blocks becoming soiled by drink/foodstuffs.
  • Reduce the nuisances associated with ants' nests.
  • Stop loss of sand by wind, rain or pressure washers.
  • Eliminate algae and lichen growth.
  • Resists blocks from fading and will eventually darken (rather than fade)
  • Extremely weather resistant.
  • Hard wearing, durable and long lasting, with a proven track record.
  • Unaffected by water or ice
  • Enhance lost colour in old blocks.
  • Provide a water resistant bond.
  • Consolidates block joint infill.
  • Provide a cleanable surface (often without the need for detergents).
  • Highly resistant to a wide range of aggressive industrial chemicals.
  • Suitable for interior work.
  • Treats pavers and joints at the same time.
  • One component ready thinned and ready for use.
  • Greatly improves resistance to tyre marking.
