HLE20 Lightweight Dry Concrete is a quality concrete suitable for general construction work in environments with normal exposure, high humidity (XC2). Ideal for: rehabilitation of weakened slabs and dilapidated slabs, filling of air cavities, drainage, insulation on land, on sloping roofs and basement walls, screeds and leveled walkways, bathroom and kitchen floor screeds, etc...

• Preparation of the substrate: clean and wet the substrates before application and wait for the water film to disappear. Prepare it with suitable meshes to reinforce the concrete.

Preparation of the mixture: always use clean, running water. Add 2.5-3 l. of mixing water per bag and mix mechanically until a homogeneous mass is obtained and applied.
Application of the paste: the minimum thickness of the application will be of 6 cms, always allowing a complete compaction of the mass. Once the kneading is done, it will be applied before the beginning of setting.

• Provide expansion joints every 50m2 and at the joints with pillars.
• In the case of roofs with road traffic, the pavement layer must be at least 8 cm thick.
• Excess water causes a decrease in resistance.
• Apply on substrates with a certain degree of absorption, humidity and perfectly set.
• Allow to set for a minimum period of 12 hours under normal conditions.
• Do not apply at temperatures below 5ºC or above 35ºC.
• Avoid frost, strong winds and exposure to intense sunlight during application.
• The addition of other material (additives, cement, etc.) can change the behavior and characteristics of the product.
