Shrink-free mortar and underfloor heating?
Shrink-free mortar, also known as leveling mortar, repair mortar, filler mortar or quick cement, is a versatile mortar specially developed for filling grooves and holes in various surfaces. What makes this mortar so attractive is its fast drying time, allowing you to quickly continue with your project. This filler mortar is known for its minimal shrinkage, which makes it excellent for bonding to underfloor heating systems. This not only improves the efficiency of the underfloor heating, but also results in more efficient energy consumption. At Solza you will find an extensive range of repair mortars suitable for various substrates, so you can always find the right product for your specific needs.
Why use shrink-free mortar?
Repair mortar offers a range of benefits that make it an essential product for floor repair and improvement. Its quick-drying property is one of its most striking advantages, allowing you to quickly continue with your project. Its easy workability and ease of application with a float make it a favorite among professionals and DIY enthusiasts. But it goes beyond just ease of use: this mortar effectively prevents cracks and sanding in the floor, creating a more durable and stable subfloor. Due to its minimal shrinkage property, repair mortar contributes to a longer lifespan of the floor, resulting in a reliable and durable end result.
What type of mortar should I use?
When choosing the right repair mortar, it is essential to know which type is most suitable for your specific situation. There are two main types of repair mortar available:
- Cement-based repair mortar / shrink-free mortar
- Gypsum-based repair mortar / shrink-free mortar
The choice between these two depends heavily on the substrate to which it will be applied. Cement-based repair mortar, for example, is excellent for concrete floors and sand-cement floors. On the other hand, gypsum-based repair mortar is ideal for application on anhydrite floors, chipboard and other gypsum subfloors.
