Product - MR. JO EP Grout-CMR

Description

Mr. JO EP Grout-CMR is a three-part epoxy grout with chemical resistance. It flows easily and works great for  machinery and heavy foundations. You can also use it on steel and concrete in areas that requires chemical resistance. The grout spreads smoothly, fills gaps quickly, and holds strong over time. So, it offers a smart and cost-effective choice for tough jobs.

• Color: Light Grey
• Pot life @25°C: 120-160 mins
• Mixing Ratio: 100:60:450 PBW
• Mixture consistency: Flowable
• Optics: Opaque

• Heavy machine base base plate fixing
• Vibration dampening
•  Post fixing
• Grouting cavities, gaps and voids in concrete

• Metal foundations must be cleaned and degreased. Sand-blasting, if feasible, provides a very good pretreatment. The bolts should be roughened with sand blasting/emery paper till the base metal is exposed. The concrete surface pretreatment should ensure that loose laitance layer and shuttering oil if any, is removed. Thorough wire brushing and cleaning with blast of hot air is recommended.. The concrete should be sufficiently cured (2-4 weeks) to avoid shrinkage cracks.
• It is advisable to prime the surface with Jpoxy’s JO range of Primers. In case there is a time lag between priming and grouting with epoxy mortar, the surface of the primed layer should be made anti-skid by sprinkling quartz sand mix no. 10 on the primed surface, when the coating is tacky.

• All the components of kit should be mixed in recommended mixing ratios.. Mixing can be carried out manually by means of a trowel. In case mechanical mixing is employed, slow speed mixers with paddles should be used to ensure minimum air entrapment. It is preferable to let the mixed formulation stand for a few minutes to let the entrapped air escape.
• Once all components are mixed the reaction proceeds, i.e. the viscosity of the mix increases, thereby the workability will decrease. The mix should be used within the pot life. Under no conditions, the mix should be used after it is gelled. Since the reaction is exothermic, large batch sizes should be avoided

• Upto 30 mm depth : Grout can simply be poured and troweled evenly.
•  30 to 50 mm depth : Grouting should be done by casting 2 or 3 layers, at a time Upto 20-30 mm thickness
•  Over 60 mm depth : Grouting should be carried out carefully using a funnel along with a flexible plastic tube to direct the grout to spots not accessible.

A1. It is a high-performance 3-component epoxy grouting system designed for:

• Machinery foundations in chemical environments
• Fixing foundation bolts, anchor bolts, and base plates
• Repairing damaged or corroded concrete where chemicals are present
• Supporting dynamic loads in industrial applications

A2. MR. JO EP Grout-CMR offers:

• Excellent chemical resistance (against acids, alkalis, solvents)
• Superior compressive and tensile strength
• Resistance to vibration and dynamic loading
• Long service life in corrosive environments

A3. No — it is ideal for any industry requiring foundation grouting in harsh or high-impact conditions, such as:

• Refineries
• Fertilizer plants
• Heavy engineering units
• Water treatment facilities

A4. It is a 3-pack system comprising:

• Resin (Part A)
• Hardener (Part B)
• Pre-blended graded aggregates/filler (Part C)

A5. Typically grey, depending on aggregate mix. Customization may be possible for specific projects.

A6.

• Mix Part A (Resin) and Part B (Hardener) thoroughly
• Slowly add Part C (Filler) and mix to uniformity
• Pour or place immediately into the prepared foundation area
• Allow it to self-level and cure

A7. Around 30–40 minutes at 25°C, depending on ambient temperature and batch size.

A8.

• Initial set: ~8–12 hours
• Heavy-duty operations: After ~48–72 hours Ensure proper curing before applying dynamic loads.

A9. Yes — it has excellent resistance to a wide range of industrial chemicals. A chemical resistance chart is available on request.

A10. Yes — it is ideal for anchoring bolts and base plates, ensuring rigidity and long-term load retention under vibration and impact.

A11. Yes — it can be trowelled or placed into formworks for horizontal patching of damaged concrete as well.

A12. Yes — it flows well under gravity into tight foundation spaces. If needed, flowability can be improved by adjusting aggregate temperature or using small vibration tools.

A13. Substrates should be dry or surface-damp, not wet or waterlogged. For damp tolerance, use a compatible primer like MR. JO Primer-UPS before application.

A14. On porous or damp concrete, it is advisable to use MR. JO Primer-MVC, LVC, or UPS, depending on substrate condition.

A15. 12 months if stored in sealed packaging in a cool, dry place (15–25°C), away from direct sunlight.
