Frequently Asked Questions About UC Leveller
Q: Can UC Leveller be used on exterior surfaces?
A: No, UC Leveller is designed for interior use only. It should not be used in external or wet areas, or over substrates subject to rising damp.
Q: How long do I need to wait before installing flooring over UC Leveller?
A: Allow 12 hours for light foot traffic and 24 hours before installing flooring at 23°C and 50% RH. Drying times can vary depending on thickness, temperature, and humidity.
Q: What is the maximum thickness UC Leveller can be applied at?
A: UC Leveller can be applied in a single coat from 3mm to 70mm. For thicknesses above 40mm, it is recommended to add 30% aggregate.
Q: Do I need to prime the substrate before applying UC Leveller?
A: Yes, porous substrates should be primed with Eco Prim T Plus diluted 1:2 with water. Non-porous substrates require undiluted Eco Prim T Plus or Eco Prim Grip Plus. Follow specific priming instructions for different substrates.
Q: How do I prepare the mix for UC Leveller?
A: Pour 3.4-3.8 liters of clean water into a container and gradually add a 20kg bag of UC Leveller. Mix with an electric mixer at 300 RPM until a homogenous, lump-free mix is obtained. Let it sit for a few minutes and remix briefly.
