Product - MR. JO Underlay-TMP

Description

Mr. JO Underlay-TMP is a three-part, solvent-free epoxy system you can tamp and spread easily. Because of this, it works well for many floor toppings and construction bedding jobs. Moreover, it creates strong bonds and lasts a long time. As a result, it improves durability and makes structures stronger. In addition, it gives a stable and reliable base for any further work.

• Color: Neutral
• Pot life @25°C: 120-150 mins
• Mixing Ratio: 100:50:650 PBW
• Mixture consistency: Tampable
• Coverage: 1.8 kg/m²/mm

• Flooring
• Pavement
• Slope for drainage
• As a bedding to enhanced floor’s mechanical strength

• Remove all dust and debris by physical and mechanical means, prior to application of the product. surfaces should be freed from laitance and dust by sand-blasting.
• In case sand-blasting is not possible, thorough abrading with a hard wire brush should be preferable.

• Repair the surface if damaged. Allow 2-3 hours for surface of repaired area to dry. Choose a suitable product from Jpoxy’s JO range of Adhesives for repairing.
• Apply primer for better adhesion on substrate. Allow 4-5 hours for surface of repaired area to dry. Choose a suitable product from Jpoxy’s JO range of Primers.
• Mix all the three components provided in kit thoroughly for at least 2minutes. Apply the mix directly by pouring and spreading with the help of trowel.
• Allow 4-5 hour for surface to dry and 24 hours to achieve strength.

A1. It's a tampable screed used to create slope, thickness (3–6 mm), or level uneven floors before epoxy topcoats.

A2. TMP is not flowable — it must be placed and compacted manually using a trowel or wooden float.

A3. All underlay products are epoxy-based screeds designed for:

• Leveling rough or uneven concrete floors
• Building thickness (1–6 mm) before epoxy topcoats
• Providing a strong, bonded base for self-leveling or roller-applied coatings

A4.

A5. MR. JO Underlay-STD is designed to be a cost-effective alternative to premium flowable systems like MR. JO Underlay-FLO. Ideal for large-scale flooring with budget constraints.

A6. Use MR. JO Underlay-CMR, a chemically resistant screed, ideal for:

• ETPs/STPs
• Chemical plants
• Battery zones
• Coastal installations

A7. They're designed as underlays. For long-term durability, especially in industrial or exposed zones, overcoat with:

• MR. JO Floor SL series
• MR. JO EcoFloor series
• MR. JO Protectokot-CMR, CR, CSA or HBCR

A8. Yes — all four underlays are compatible with:

• MR. JO Floor-SL0.5 / SL1 / SL2
• MR JO EcoFloor-SLP, SLB, SLS
• MR JO Floorkot-HB or CMR

A9. Yes. Choose based on surface:

• MR. JO Primer-MVC or LVC for dry, well-prepared concrete
• MR. JO Primer-UPS for damp or underprepared surfaces

A10. 

• FLO / STD: Pour, spread using trowel or notched rake, level out
• TMP / CMR: Place with trowel, tamp/compact manually

A11. Yes, especially if you're planning to overlay with screed, tile mortar, or non-epoxy layers. Broadcast dry quartz sand on the wet underlay before full cure.

A12. No. Underlays are not designed to be pigmented. They come in neutral (reddish-brown or grey) tones since they are not exposed.

A13. Use MR. JO Tecseal-CRP to patch and repair before primer and underlay application.

A14. All systems offer a working time of 30–40 minutes at 25°C. Always mix only as much as you can apply within that window.

A15. Typically after 8–12 hours, once surface is touch dry. Ensure it's clean and dust-free before applying topcoat.

A16. Short term, yes — but for long-term protection, always apply a proper epoxy flooring or coating.

A17. Yes:

• TMP and CMR can be used for patch repairs or pothole filling
• Add extra sand or filler as needed for volume
