High strength pourable epoxy resin grout(EP)
EP is a three-component pourable grout, based on a solvent free epoxy resin and selected aggregates. EP cures to form a hardened mortar with excellent adhesion to many substrates. This combined with the product’s ease of application makes it ideally suited to site application.
It is mainly applied for repairing of concrete substrate which includes 1-15mm uneven surface and 15-100mm deep hole.
As a self smoothening mortar: Repairing and patching horizontal surfaces.
High early strength
High tensile and flexural strength, vibration resistant.
Unaffected by wide range of chemicals
Storage and Shelf life
Minimum shelf life is 1 year. Store under controlled conditions in original containers from 5 – 35 ℃.
Instructions for Use
1. Surface Preparation
Mechanically roughened, free from all contaminants (Eg. Dust, oil, grease, ice, etc.), surface water, laitance, old form oil, curing membrane and old coatings. Suitable methods of preparation include blast cleaning and scrabbling (sanding/grinding on fibrous cement). All dirt must be removed from bolt by air blasting.
2. Primer Application
Apply #3 Epoxy resin primer tack coat application method for substrate surface treatment. Apply by brush, roller or squeegee and scrub well into substrate. When maximum waiting times are expected to be exceeded lightly broadcast with kiln dried quartz sand (0.4 – 0.7 mm) at a maximum of 1.0 kg/m2. Remove excess before application of second coat.
Second coating layer # 5 Epoxy resin primer should be applied ( while the substrate exposed in the air. Therefore, the first layer should be brushed carefully. When the second coating applied after more than 48 hours, broadcast with dried quartz sand (0.4 – 0.7 mm) at a maximum of 0.8kg/m2. Attentions should be taken to avoid excessive quartz sand in the primer.
EP is supplied in factory proportioned units comprising the correct quantities of Part A (resin), Part B (Hardener) and Part C (Aggregate). Thoroughly stir Parts A and B separately using a slow running drill stirrer with a spiral mixer. Decant all the Part B into Part A and mix thoroughly together until a uniform mix is achieved (typically 2 minutes). Continue to mix whilst adding Part C slowly. Ensure the attainment of an even color and an even distribution of aggregate throughout the mix.
Reduce quantity of component C if high material flowable required; Regulate proportion of component A and component B if application should be extended. For example, regulate the mixing proportion of component A to component B in 6: 1 instead of 5: 1. The actual mixing proportion should be confirmed by the test at site.
Generally, suitable thickness depends on clearance, distance of flow, ambient and substrate temperatures and pour size. Maximum thickness in each pour is 50mm.
Being an epoxy, no special curing techniques are required. Curing time will depend on the quantity and the ambient temperature. High volumes and high temperatures result in short curing times. Do not install equipment or load the epoxy before full cure.
Uncured material may be cleaned from application tools, etc. Using MUHU-cleaner (flammable solvent). Cured material can only be removed mechanically.

Do not apply EP to surfaces with standing water.
Only mix as much as can be applied within the stated potlife.
Do not dilute the product with solvent as this will affect both the cure and in-service performance.
Avoid contact with the skin, eyes and avoid breathing it’s vapor.
Wear protective gloves when mixing or using.
If poisoning occurs, contact a doctor or Poisons Information Centre.
If swallowed, do NOT induce vomiting. Give a glass of water.
If skin contact occurs, remove contaminated clothing and wash skin thoroughly.
If in eyes, hold eyes open, flood with water for at least 15 minutes and see a doctor.
