Description

Mr. JO Protectokot – BLK is a two-part epoxy coating. It is solvent-free and non-porous. It has medium thickness and resists chemicals. Moreover, it blocks water and keeps surfaces safe. As a result, it lasts long and works in many places. In addition, it is great for effluent plants, chemical zones, and terraces. Furthermore, it is easy to use and low-cost. That is why many industries trust it for protection.

  • Color: Black
  • Pot life @25°C: 25-35mins
  • Mixing Ratio: 100:100 PBW
  • Mixture consistency: Brush able liquid
  • Excellent saline water resistant
  • Coverage : 4 m2/kg/coat
  • Optics : Opaque
  • ETP plants
  • Tank inner lining
  • Waterproofing
  • Corrosion protection
Surface Preparation
  • The mixture should be applied on a clean and rough surface. For good results, it is required that the substrate is free from loose particles
  • Suitable degreasing agent should be used to remove any grease, oil or traces on the surface
Application Method
  • 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 the two components in small batches thoroughly for at least 2minutes. Apply the mix using brush or spatula to the pretreated surfaces
  • Allow 4-5 hours for surface to dry and 24 hours to achieve full strength.

Q1. What is MR. JO Protectokot – BLK used for?

A1. It is a tar-based epoxy coating designed to:

  • Protect concrete and metal surfaces exposed to chemicals and water
  • Coat effluent treatment plants (ETP), sewage tanks, drains, and marine structures
  • Provide a cost-effective waterproofing and abrasion-resistant layer for industrial areas
Q2. What makes this different from standard waterproofing coatings?

A2.

  • Superior chemical and salt water resistance
  • Good film flexibility and long-term adhesion to concrete
  • Can also serve as a structural repair screed when filled with quartz sand
Q3. Is it suitable for sea-facing concrete and marine zones?

A3. Yes — Protectokot-BLK offers exceptional resistance to salt spray, moisture, and marine conditions, making it ideal for docks, jetties, and coastal structures.

Q4. What color is the coating?

A4. It is available only in black due to its tar-based composition.

Q5. Is it suitable for waterproofing use as well?

A5. Yes. While primarily a protective barrier, it also offers very effective waterproofing in demanding industrial conditions.

Q6. What is the recommended mix ratio?

A6. 100:100 by weight (Resin : Hardener). Mix thoroughly until the blend is uniform.

Q7. How many coats are needed? A7. 2–3 coats are recommended for:
  • Full waterproofing
  • Chemical barrier
  • Long-term protection from abrasion and corrosion
Q8. Can MR. JO Protectokot – BLK be used on damp surfaces?

A8. It should be used on dry or slightly damp surfaces, not on visibly wet or submerged areas. For saturated conditions, use appropriate damp-tolerant primers first.

Q9. Can I add filler to make it thicker or use as repair mortar?

A9. Yes — it can be mixed with quartz sand to form a cost-effective, chemical-resistant screed for:

  • Pothole filling
  • Concrete patch repair
  • Lining buildup before topcoat

Q10. What is the coverage per coat?

A10. Approximately 3.5–4.5 m² per kg per coat, depending on surface roughness and porosity.

Q11. What are the ideal application tools?

A11. Use a roller, brush, or trowel (when using filled/screed form). Apply evenly and avoid air entrapment.

Q12. How long does it take to cure? A12.
  • Touch dry: ~6–8 hours
  • Next coat: After 8–12 hours
  • Full cure: 5–7 days (for maximum chemical resistance)
Q13. Can I overcoat it with tiles, screed, or other protection layers?

A13. Yes — for best results, sprinkle clean quartz sand onto the wet topcoat to allow screed, tile mortar, or other overlays to bond securely.

Q14. Is it resistant to acids, alkalis, or industrial chemicals?

A14. Yes — Protectokot-BLK offers excellent resistance to a wide range of chemicals. A detailed chemical resistance chart is available on request.

Q15. Are there any limitations to be aware of?

A15.

  • It is available only in black
  • Not UV stable — not recommended for permanent outdoor exposure
  • Contains tar — may not be suitable for decorative or hygiene-sensitive environments
Q16. How should the surface be prepared?

A16.

  • Clean, dry, and free from dust/oil
  • Mechanical roughening (grinding/blasting) is preferred for better adhesion
  • Repair structural defects with MR. JO Tecseal-CRP before coating
Q17. Is MR. JO Protectokot – BLK a high-build coating?

A17. Yes. Protectokot – BLK is a solvent-free, high-build epoxy coating that allows application of thicker layers (200–300 microns per coat) without sagging or running. This makes it ideal for:

  • Rough and porous surfaces
  • Vertical applications
  • Areas needing extra chemical and abrasion resistance in fewer coats

Its high-build property reduces the number of applications needed while ensuring a robust, long-lasting barrier.

Q18. What known products does MR. JO Protectokot – BLK compare with?

A18. MR. JO Protectokot – BLK is functionally comparable to systems based on Araldite GY255 resin and Aradur XY45 hardener, which are commonly used in tar-based, chemical-resistant protective coatings. It offers similar performance in effluent treatment, marine environments, and concrete waterproofing, but is supplied as a ready-to-use system with optimized formulation.
