1. Are there walls too, or just the floor? → Walls too: LR | Just the floor: continue
2. Is it urgent? (Do you want to install the flooring after 2 hours?) → Yes: LR | No: continue
3. Will vinyl, PVC, rubber or LVT flooring be installed? → Yes: Ultra | No: continue
4. Commercial traffic/restaurant/hotel? → Yes: Ultra | No: continue
5. Large area (50+ m²), do you have time? → Eco

12,550 HUF / 25 kg

When is it needed?

• Large area (50+ m²) in one application
• You have 24 hours to wait
• Floor only (no walls)
• Ceramic or stone flooring will be installed

Example: 150 m² office, 5 mm levelling, new porcelain tile flooring.

Why this one?

• 4-hour pot life: You can work with one mix for hours. No remixing, no rushing.
• Thixotropic: Stays in place even on sloped surfaces.
• Lower price: You do not pay for features you do not use (rapid setting, wall application).

Material cost example (50 m², 5 mm):

• Eco: 50 × 5 × 1.5 kg = 375 kg ≈ 15 bags = 188,250 HUF
• Time: 2 days (levelling + 24 hours + tiling)

When is it NOT suitable?

• Walls are also involved → LR is needed
• Urgent (must be ready by tomorrow) → LR is needed
• Vinyl flooring will be installed → Ultra is needed
• More than 10 mm is needed in one layer → LR is needed

Technical:

• CT-C25-F6
• 1–10 mm (maximum in one layer)
• Walkable after ≈24 hours
• Suitable for ceramic tiling after ≈24 hours, parquet after ≈3–5 days
• ≈1.5 kg/m²/mm
• Rating 2

Maximum layer thickness: 10 mm in one application. If more is needed: 10 mm first layer → wait 24 hours → 10 mm second layer.

HUF 17,750 / 25 kg (+41% vs. Eco)

When do you need it?

• You want to install the covering after 2 hours
• There are also walls (shower, stairs)
• You need a thick layer (up to 25 mm in one pass)
• tender (Rating 5 required)

Example: Shower renovation — the wall is uneven and it needs to be ready by tomorrow.

Why this one?

• Ready for covering after 2 hours: Level in the morning, install the covering in the afternoon. Project completed in one day.
• Suitable for walls: Thixotropic + rapid setting = it does not slide down vertical surfaces.
• 25 mm in one layer: No repeated application, no waiting between layers.
• Rating 5: Required for green building projects (LEED, BREEAM).

Material and labor cost calculation (50 m², 5 mm, floor only):

• LR: 50 × 5 × 1.3 kg = 325 kg ≈ 13 bags = HUF 230,750 in materials
• Eco: 375 kg = HUF 188,250 in materials
• Difference: +HUF 42,500 in materials | BUT: -1 day of labor (HUF 40,000–60,000) → LR is cheaper overall

Why is the material more expensive?
Rapid-setting technology — special additives. But if the project is completed one day faster, the labor savings offset the additional material cost.

When is it NOT suitable?

• No rush, large area → Eco is cheaper
• Vinyl flooring will be installed → Ultra is required (smooth surface)
• You work slowly → 20 minutes of pot life may be too short

Technical:

• CT-C20-F6
• 1–25 mm (in one layer!)
• Walkable after ≈2 hours
• Ready for ceramic covering after ≈2 hours, parquet after ≈12 hours
• ≈1.3 kg/m²/mm
• Suitable for application on vertical surfaces
• Rating 5

Maximum layer thickness: 25 mm in one pass — this is LR’s greatest advantage. If more is needed: 25 mm first layer → wait ≈2 hours → second layer.

20,300 HUF / 25 kg (+62% vs. Eco)

When is it needed?

• Vinyl, PVC, rubber, LVT flooring is being installed
• An ultra-smooth surface is required (resilient flooring does not hide imperfections)
• Commercial traffic (restaurant, hotel, office with wheeled chairs)
• The project is on a ship (marine certification)

Example: 300 m² restaurant, rubber flooring, 500+ guests per day.

Why this product?

• C30-F7 strength: 30 N/mm² — the strongest in the range. For commercial loads.
• Ultra-smooth surface: Adhesive for vinyl/PVC/rubber flooring does not telegraph through, and ridges are not visible.
• EN 12529 rolling loads: Restaurant trolleys and hotel luggage carts — every day.
• Marine-certified: IMO marine standard (vibration, temperature changes).

Price comparison (50 m², 5 mm, vinyl flooring):

• Ultra: 50 × 5 × 1.9 kg = 475 kg ≈ 19 bags = 385,700 HUF in materials
• Eco: 50 × 5 × 1.5 kg = 375 kg ≈ 15 bags = 188,250 HUF in materials
• Difference: +197,450 HUF in materials | BUT: bonding vinyl with Eco can be problematic → it must be redone → +150,000–200,000 HUF in repairs
• Ultra is worth it: Preventing the problem is cheaper than repairing it.

Why is it the most expensive?

• C30 strength (vs. C25 Eco): higher cement and aggregate content
• Ultra-smooth formula: special particle-size distribution
• Marine certification: additional testing and compliance certification

When is it NOT suitable?

• Ceramic flooring is being installed → Eco or LR is cheaper; C25/C20 is sufficient
• Residential area only, with no commercial traffic → Eco is sufficient
• Walls are also involved → LR is required (Ultra cannot be applied to walls)

Technical:

• CT-C30-F7
• Up to 20 mm (in a single layer)
• Ready for vinyl/rubber flooring in ≈2 hours, ceramic flooring in ≈6 hours
• ≈1.9 kg/m²/mm
• EN 12529 rolling loads
• IMO marine certification
• Rating 3

Maximum layer thickness: 20 mm in a single application.

Important: Moisture measurement is mandatory. Maximum 2% CM (cement), 1% (gypsum). Damp substrate = no adhesion.

1. Hotel bathroom (20 m², walls + floor)

Chosen: Keralevel Eco LR
Why? There was a wall surface too (shower area), and it had to be ready by tomorrow. 2 hours before tiling + vertical surface = LR.

2. Office vinyl flooring (150 m²)

Chosen: Keralevel Eco Ultra
Why? LVT flooring — an ultra-smooth surface is required, with commercial use (30 people, office chairs). C30 strength + vinyl compatibility = Ultra.

3. Apartment porcelain stoneware flooring (80 m²)

Chosen: Keralevel Eco
Why? Large area, with 2 days available, and ceramic tiles. 4-hour pot life = one mix for the entire area. Lower price. Eco.

4. Restaurant renovation (200 m², rubber flooring)

Chosen: Keralevel Eco Ultra
Why? Rubber flooring + 300 guests per day + heavy equipment in a commercial kitchen. C30 strength + EN 12529 rolling load resistance = Ultra. The repair cost (if it were done incorrectly with Eco) would have exceeded the price of Ultra.

5. Stairwell renovation (walls + stairs)

Chosen: Keralevel Eco LR
Why? A vertical surface (wall) + the sloping surface of the stairs. Only LR is suitable for vertical/sloping surfaces. There is no alternative.

Keralevel LR or Ultra for faster vinyl flooring installation?
Ultra. LR can be tiled after 2 hours for ceramic tiles, but for vinyl/resilient flooring, Ultra provides an ultra-smooth surface. LR is not optimized for resilient floor coverings.

Why isn't Ultra the best choice everywhere?
For ceramic tiles, C30 strength is unnecessary — C25 (Eco) is more than sufficient. You would be paying extra for a feature you do not use. If there is no vinyl flooring and no commercial traffic, Ultra is wasteful.

Can Eco be used on walls?
No. It will slide down. Only LR can be used on walls — its thixotropic formula combined with rapid setting ensures that it stays in place on vertical surfaces.

Why is LR more expensive if it is weaker (C20 vs. C25)?
Because its speed comes not from its strength, but from its specialized rapid-setting technology. C20 is sufficient for residential and commercial use. The premium lies in the time saved, not in the strength.

Is there a cheaper alternative to Ultra for vinyl flooring?
There is no safe alternative. If the substrate is not ultra-smooth, bonding the vinyl can be problematic, as the flooring will reveal any unevenness. The cost of repairs (re-bonding or possibly replacing the flooring) will exceed the price of Ultra.

Which one is the “best”?
There is no “best” option, only the one that is “right for the project”:

• Eco: Large area, no rush → best (most economical)
• LR: Wall application or urgent work → best (the only solution for walls)
• Ultra: Vinyl flooring or commercial traffic → best (a trouble-free end result)

❌ Applied to a damp substrate → It will not adhere and will flake off
✅ Solution: Use a moisture meter — max. 2% CM (cement), 1% (gypsum). Damp substrate = wait for it to dry or dry it.

❌ No primer → Poor adhesion, cracking, dusty surface
✅ Solution: Use a primer suitable for the substrate (see the table above)

❌ Not de-aerated (no spiked roller) → Air bubbles, weak surface, cracking
✅ Solution: Roll over the surface with a spiked roller within 5–10 minutes of application — mandatory!

❌ Layer too thick in a single application (e.g. Eco 15 mm) → Cracking, drying problems
✅ Solution: Observe the maximum layer thickness: Eco 10 mm | LR 25 mm | Ultra 20 mm

❌ Flooring installed too quickly → The substrate is not yet sufficiently strong and the flooring may lift
✅ Solution: Observe the waiting time: Eco 24 hours | LR 2 hours | Ultra 2–6 hours

❌ Incorrect water-to-powder ratio → Too runny: low strength | Too thick: does not level, air bubbles
✅ Solution: Measure precisely — 25 kg powder + 6–6.5 litres of water (depending on the product)

❌ Dusty, loose substrate not cleaned → Poor adhesion, delamination
✅ Solution: Vacuuming + primer. If very loose: mechanical cleaning (sanding, chiselling).

Keralevel Eco LR is unique: ready for tiling in 2 hours + suitable for vertical surfaces. This combination is rare on the market. If the project is urgent AND there are walls to cover, LR solves both problems.

Keralevel Eco Ultra: C30-F7 strength + marine certification + vinyl-optimized. C30 strength (30 N/mm²) is an advantage in commercial applications, while the marine certification (IMO) proves its resistance to extreme conditions.

Keralevel Eco: 4-hour pot life + thixotropic. On large areas (50+ m²), there is no need to remix—you can work with a single mix for hours.

Important: If you find a better alternative for your project, use it. We are not saying that Keralevel is the best choice everywhere—we are saying that in these situations (fast + walls, vinyl + C30, large area + long pot life), Keralevel solves the problem effectively.
