Application Guide

1. Subfloor Preparation: Eliminate oil stains, dust, and loose debris. Use sanding techniques to smooth irregularities. Seal any leaks to ensure the surface is dry. For summer projects, lightly dampen the ground and allow to dry before application.

2. Interface Treatment: Use water-based absorbent interface agents for high-absorbency substrates or non-absorbent agents for smooth surfaces.

3. Mixing: Calibrated at a precise 22% water-to-mortar ratio. Add 5 liters of water to 25kg of repair mortar. Mix thoroughly until smooth and homogeneous.

4. Execution: Pour material into the repair area. Use a trowel for even distribution and a roller to remove air bubbles for a flawless finish.

Important Notes

Maintain application temperatures between 5ºC and 30ºC.
Strictly follow the specified water-to-product ratio.
Apply material within a 20-minute window after mixing.
Avoid contact with eyes or skin; protect the surface from heavy objects and water during curing.
Store in a dry, cool, well-ventilated area away from direct sunlight.

Frequently Asked Questions

What is the ideal application thickness for this mortar?
The K12 mortar can be applied in thicknesses ranging from 8mm to 30mm. If applying a layer between 20mm and 30mm, we recommend adding 8kg of quartz sand per bag for enhanced durability.
How much water is required for mixing?
The water-to-mortar ratio is strictly 22%. For a standard 25kg bag, you should use exactly 5 liters of water to ensure optimal flow and strength.
How much time do I have to work with the mixed material?
The working time is approximately 20 minutes after mixing. It is crucial to pour and level the material promptly within this window to prevent premature setting.
Can this mortar be used for outdoor projects?
Yes, it is suitable for both indoor and outdoor renovations. However, for outdoor projects, avoid application during rain or in direct, intense sunlight.
What is the compressive strength of the finished surface?
The finished surface achieves a high compressive strength of 45 MPa, making it durable enough for professional flooring repairs and heavy-duty use.
Is a primer necessary before application?
Yes, a primer is essential. Use LG660 for absorbent surfaces or LG670 for non-absorbent surfaces to ensure superior bonding and a bubble-free finish.
