Where to use?

  • Transverse or longitudinal vertical joints
  • Patch repairs
  • Trench reinstatements
  • Drain or manhole frames
  • Kerb channels

Preparation

Ensure that the joints to be sealed are clean and free from dust, fuel and oil spillage. The face of the joints should be dry with a surface temperature ideally of at least 10°C. Do not apply to icy surfaces or in rain.

Application

H4 Polymer must be heated before use.

For best results, use a heating kettle with an indirect heating system such as hot oil. Ensure that H4 Polymer doesn’t exceed 200°C and that the oil does not exceed 230°C. When hot, pour either from a watering can or direct from the melting kettle via a pressure fed heated hose with a special nozzle. The 25kg tin pails are not suitable for placing on or over direct heat (i.e. gas or wood fire).

Coverage

For a 40mm vertical joint face and a 2mm coated thickness of H4 Polymer: 0.08kg of H4 Polymer seals approximately one linear metre of joint or a 25kg pack seals approximately 300 linear metres of joint.

Packaging

H4 Polymer is supplied in 25kg metal pails with handles (24 x 25kg per pallet) being leak proof, these pails are particularly convenient for use during hot weather.

Storage

Keep free from frost and extremes of heat. Do not stack. Do not store in direct sunlight.

Standards

H4 Polymer is a CE Marked paving grade bitumen complying to BS EN14023:2010 which also complies with BS 594987 clause 6.8 Joints. H4 Polymer is suitable for jointing as required in Clause 903.22(ii) of Volume 1 of the Specification for Highway Works.
