Question 1

What is the difference between self-levelling compound and floor screed?

Accepted Answer

Self-levelling compounds are specially engineered to flow and settle into place, creating a smooth, level surface without the need for extensive manual intervention. This makes them ideal for quick applications where a flat surface is essential, as they can adjust to low spots and correct unevenness effectively. In contrast, traditional floor screed is typically applied in thicker layers, ranging from 15mm to upwards of 75mm, depending on the requirements. It requires manual smoothing to achieve the desired finish, making it better suited for substantial applications, such as height adjustments or providing a strong base for underfloor heating systems. Understanding these differences is crucial for selecting the appropriate material for your flooring project, ensuring optimal performance and longevity.

Question 2

Can I use self-levelling compound on plywood?

Accepted Answer

Yes, self-levelling compound can be used on plywood surfaces; however, it's essential to ensure that the plywood is securely fastened and properly prepared prior to application. This preparation should include cleaning the plywood surface thoroughly to remove any dust, dirt, or debris, and applying a suitable bonding agent to enhance adhesion and reduce the likelihood of cracking. Additionally, always reference the manufacturer's guidelines for the specific self-levelling compound you plan to use, as some products may have particular requirements for application over plywood. Proper preparation and adherence to guidelines will help ensure a durable and long-lasting finish, providing peace of mind for your flooring project.

Question 3

How long does self-levelling compound take to dry?

Accepted Answer

The drying time for self-levelling compound can vary considerably based on factors such as the product used and the environmental conditions during application. Generally, most self-levelling compounds can be walked on within 24 hours, although full curing may take up to a week, especially if applied in thicker layers. For those in a hurry, fast-setting compounds are available that can dry in as little as 4 to 6 hours, making them ideal for rapid renovations. It's crucial to follow the manufacturer's instructions regarding drying times and consider environmental factors like temperature and humidity, which can significantly affect the curing process. Always ensure that the compound is completely cured before laying any floor coverings to achieve the best results.
