Product benefits

  • Resistance to heavy mechanical stress
  • Anti-skid property
  • Highly chemical resistant

Free flowing high strength epoxy grout

webertec epo 430 GRT Plus is a three-component high flow epoxy grout: resin, hardener and specific fillers. The mix of these components gives a very resistant, waterproof and non-shrink resin grout.

webertec epo 430 GRT Plus is particularly recommended for grouting and bedding applications where it is used for its fluid consistency.

Instructions for use

Product preparation

Before application, the resin and the hardener components are carefully mixed with a slowly rotating electric drill with paddle. To complete mixing, the resin is poured progressively from one can to another and mixed again. Then the mineral charge is mixed with the binding resin by means of a forced action mixer. Add the mineral charge progressively while mixing until a homogeneous consistency is obtained. Add all the quantity of the filler to the epoxy.

Product application

Surface preparation

The concrete should have at least 28 days setting. The substrate must be clean and free from all loose particles, dust, cement laitance, rust, oil and other contaminants. The minimum concrete compressive strength necessary should be 25 MPa. The substrate must not contain more than 6% moisture.

Product application

The mortar is leveled with a trowel made wet with solvent.

The application admissible thickness is 3 mm up to 50 mm. Thicknes up to 450 mm can be achieved making sure that no bleeding will appear due to site condition, temperature or bad mixing.

Do not add water or solvent to the mix. Application and substrate temperature : from 8 to 30ºC. Relative ambient humidity ≤ 85%.

Environmental and Safety

Safety precautions

Application should be done in a ventilated area away from any heat source. Wear protective gear for hands and eyes and avoid breathing of vapor. If mixed resin comes into contact with the skin, it should be promptly removed before hardening, followed by thoroughly washing the skin with soap and water. In case of heavy vapor inhalation, place affected person in an open-air area. In case of contact with eyes, wash thoroughly with clean water. If swallowed, do not induce vomiting. In all cases, seek medical attention. In case of fire, use CO2 foam to extinguish. Tightly seal containers when not in use, store them away from heat and carefully dispose empty ones.
