This product is specifically designed for filling and levelling holes and indentations on screeds, stairs, and stages. The mortar is stable, fine-grained, fast-drying, and low-porosity, ensuring a smooth and solid substrate. It is suitable for various substrates such as mastic asphalt, concrete, calcium sulfate screeds, chipboards, and more. With a quick drying time and high strength, Stauf Shrink-Free Mortar RM provides a reliable foundation for further flooring applications.
How the product works
Stauf Shrink-Free Mortar RM works by forming a homogeneous mass that can be easily distributed and smoothed. Mix the mortar in a clean container with the correct amount of water, stir evenly, and ensure a smooth consistency. Apply the levelling compound with a trowel or spatula and spread evenly over the substrate. The mortar dries quickly and is walkable after 30 minutes at 20°C. It is ready for bonding after about 2 hours. This product can be applied in layer thicknesses ranging from 1 to 50 mm, depending on additions such as quartz sand.
Advantages and properties
Stauf Shrink-Free Mortar RM offers numerous benefits. It is approved for underfloor heating and provides high strength and crack-free results, even with thicker layers. The mortar is stress-reducing and complies with DIN 12592 for chair castors. Additionally, it is free of flammable components and meets the DIN EN 13501 standard for fire safety. The mortar has a working time of 15 minutes at 20°C and 65% relative humidity, making it ideal for quick and efficient floor renovations.
Instructions for use
Before using Stauf Shrink-Free Mortar RM, the substrate must be thoroughly prepared. Ensure that the substrate is dust-free, firm, sufficiently rough, and dry. Mix the mortar with clean, cold water according to the recommended ratios and stir until a homogeneous mass is obtained. Apply the levelling compound with a trowel or spatula and spread evenly. Protect the mortar from direct sunlight and drafts during curing. For thicker layers, the mortar can be extended with quartz sand. After complete curing, the floor covering can be applied.
Maintenance and additional tips
For the best results with Stauf Shrink-Free Mortar RM, it is important to control the ambient temperature and humidity during application.
