What is K‑10 Polyurethane Plus / Sikalastic 562?

Explain that it is a one-component, water-based polyurethane membrane with crack-bridging properties, UV resistance, and excellent adhesion. Mention its lightweight, eco-friendly, and easy-to-apply nature.

 K-10 Polyurathane Plus, now rebranded as Sikalastic®-562 IN, is a one-component, water-based, cold-applied liquid polyurethane membrane designed for waterproofing. 

Because it is water-based, it is more user-friendly (low odor, easy cleanup) and safer than many solvent-based systems. As a single-pack system, it requires no mixing of multiple parts — you apply it straight from the container.  It forms a seamless, elastic membrane that offers excellent crack bridging and UV resistance.

Key Benefits of K‑10 Polyurethane Plus (Sikalastic 562)

1. Seamless, Durable Waterproofing

K‑10 Polyurethane Plus forms a continuous, seamless membrane that fully covers surfaces without gaps or joints. This prevents water seepage and ensures long-lasting protection for terraces, roofs, balconies, and walkways. Unlike traditional sheet membranes, there’s no risk of overlaps or weak points.

2. Crack-Bridging Capability

One of the standout features of Sikalastic 562 is its ability to bridge small cracks in the substrate. The elastic nature of the membrane allows it to stretch and contract with building movements, preventing leaks and damage caused by structural shifts.

3. Cold-Applied, Easy to Use

The product is ready to use and cold-applied, eliminating the need for heat, torches, or complex mixing. This makes application faster, safer, and more convenient, even in residential or semi-enclosed areas.

4. Strong Adhesion to Multiple Surfaces

 K-10 Polyurathane Plus adheres strongly to a wide variety of surfaces, including concrete, masonry, metal, tiles, and even old bitumen coatings. This versatility ensures that it can be used for both new construction and renovation projects without special primers in most cases.

5. UV and Weather Resistant

The membrane is resistant to ultraviolet (UV) rays and extreme weather conditions, making it ideal for exposed roofs and terraces. It maintains performance even under intense sunlight, heavy rain, or ponding water, ensuring durability over time.

6. Environmentally Friendly and Low Odor

Being water-based and low VOC, K‑10 Polyurethane Plus is safe for use in occupied spaces. It produces minimal odor and does not release harmful solvents, making it suitable for both residential and commercial applications.

7. Quick Curing and Maintenance-Friendly

The membrane cures quickly, allowing early traffic or covering with tiles after proper drying. Maintenance is simple: the seamless surface can be easily inspected and repaired if necessary, saving time and cost over the life of the structure.

Cost-Effective Long-Term Solution

By preventing leaks, water damage, and structural deterioration, K‑10 Polyurethane Plus reduces the need for frequent repairs. Its long service life makes it a cost-effective solution for waterproofing in both new construction and renovations.

FAQs

Q1: Is Sikalastic 562 the same as K-10 Polyurethane Plus?
Yes. Sikalastic 562 IN is effectively the successor or rebranded version of what was earlier known as Davco K10 Polyurethane Plus in many markets. 

Q2: On which substrates can this be used?
It can adhere to a wide range of surfaces: concrete, masonry, brick, bitumen membrane, metal, old tiles, clay tile surfaces, bituminous coatings, etc. 

Q3: Can I apply it over damp concrete?
Yes, provided the substrate is visibly dry (no standing water) and free of moisture film. It tolerates mild dampness but not wet surfaces. 

Q4: How many coats and what thickness is needed?
Typically two coats are applied at cross direction for full coverage. A dry film thickness of ~1 mm or more is recommended.

Q5: How long before traffic or covering?
After the second coat, full cure may take 6–8 hours (or more depending on temperature and humidity) before tiling or light traffic.
