Structure type

Detail

Finish coating on a natural hydraulic lime NHL 3.5 screed.

Application cycle

1. Mix of lime and cork, perlite, expanded clay or other lightweight aggregate, at least 5 cm thick, laid on the floor structure as a lightweight insulating screed that can also house the building services and provides an even surface for laying the screed.
2. Existing screed or RALLK Massetto Kalce based on NHL 3.5 natural hydraulic lime, 4 cm thick or more, with or without radiant heating.
3. RALLK Marmo K Floor finish coating, also available in custom earth tones, based on air lime, NHL 3.5 natural hydraulic lime and celluloses, for smooth, walkable marmorino-effect surfaces that can later be ground if desired and protected with natural or synthetic waxes.

Additional information

1. When laying the finish coating on existing screeds, check that they are sound, cohesive and free of hairline cracks.
2. When laying the finish coating on existing screeds with cracks, first establish their cause and make sure they are stable and no longer developing. For cracks wider than 1 mm, open them up and fill them with RALLK Kerasiv Kalce powder adhesive, based on NHL 3.5 natural hydraulic lime, embedding a 150 g/m² glass fiber mesh if needed.
3. If required, the finish coating can be ground or sanded 1-2 weeks after laying, and in any case only after checking that it has reached sufficient strength.
4. See the individual product data sheets for application methods and precautions.
