Soudal HB Construct - Extra Strong D4 Hybrid Polymer Adhesive

Soudal | Hybrid Polymer Adhesive

Special Offer

Soudal HB Construct is an Extra Strong, Heavy Duty, Hybrid Polymer Based Construction Adhesive with D4 Strength and excellent water resistance.

Soudal HB Construct works differently to PU Adhesives as there is no 'foaming' action whilst curing therefore clamping is NOT required, however the product still maintains an amazing end strength of up to 110kg/cm².

Supplied in 290ml Cartridges, Brown (RAL 1001) in colour.


Soudal HB Construct - Extra Strong D4 Hybrid Polymer Adhesive

Soudal HB Construct is a Unique, Hybrid Polymer Based, D4 Strength, Construction Adhesive with Extra Strong Adhesion, is Waterproof and does not 'foam' whilst curing, eliminating the need to clamp. Soudal HB Construct has an end strength of up to 110kg/cm².

Soudal HB Construct can be used to bond many substrates in the building, joinery and construction industry, including wood, wood based materials, glass, aluminium, steel, many types of plastics, tiles, concrete, brick etc. At least one of the surfaces should be porous.

Soudal HB Construct is not suitable for use on PE, PP, PTFE or Bitumen.

Product Benefits:

  • Isocyanate Free Construction Adhesive

  • No Black Fingers

  • Water Resistant D4 (DIN EN 204)

  • Non Foaming

  • Suitable for Interior and Exterior use

  • Self-Levelling Product - Flows to Fill Connections

  • End strength up to 110kg/cm²

  • Clamping NOT Necessary

  • Can be Finished Immediately After Application

  • High Heat Resistance

Typical Applications:

  • Suitable for the bonding of non-carrying bondings between different sorts of wood.

  • Specific for bondings with a wooden seam which will remain visible.

  • Suitable for all fitting outside connections which are exposed to weather effects: doors, windows, other constructions which are in a need of a D4 water resistance classification.



Surface Preparation:

For a better adhesion on Wood, it's recommended to roughen the surface with a P80 Grit Sanding Paper.

Metal has to be free of rust and roughened at a St 3 level (according to ISO 8501-1). Both substrates have to be even and / or well matched.

We recommend a preliminary adhesion test on any substrate.

Application Method:

  • Application Method: Apply HB Construct with a caulking gun in equal beads or dots. Close within 6 minutes, press well and fixate while curing until hand tight (Approx. 60 min). Wipe away excess product with a cloth. Cured product can only be removed mechanically.

  • Cleaning: HB Construct can be removed from tools and surfaces with a Surface Cleaner, White Spirit or Swipex Hand Wipes, before curing. Cured HB Construct can only be removed mechanically.

  • Repair: With the same material


  • Do not use in applications where continuous water immersion is possible.

  • The end strength of HB Construct is equal or higher to similar PU construction adhesives.

  • HB Construct is self-leveling and therefore cannot be used for vertical joints.

  • Sufficient moisture needs to be able to reach the adhesive layer to cure. This depends on the type of material, structure of the surface, thickness of the material, air humidity and temperature.

  • HB Construct requires sufficient moisture to cure. In dry environments it is recommended to apply the adhesive onto both surfaces and then to spray a fine mist of water on top of the adhesive. CAREFUL: moistening the substrates too much prior to applying the adhesive will have a negative impact on the bond strength of the product.
