Morcem® Estuco Grueso CR CSII W2

Composition

Lime and cement based product, with balanced grain size distribution aggregates, and other additives.

Features and applications

• To be applied directly on the brickwork. No need for a previous plastering.
• To be applied indoors and outdoors.
• Permeable to water vapour, allowing the substrate to breathe.
• No cracking.
• Environmentally friendly, this product is included in the "Green Line."

Substrates

• Conventional cement and brickwork based substrates.
• Substrates must be resistant, stable, sound and clean, free of dust, demolding agents, organic products, etc.
• In case of hot or windy weather conditions or when applying over absorbent substrates, it is advisable to wet the substrate and wait till the thin layer of water disappears.
• In particular points (union between different materials, top slabs, pillars, roller blind boxes, angles in the door and window frames, etc.), prepare the mortar with glass fibre mesh to avoid fissures.
• With low-porosity substrates, apply a priming coat (IMPLAFIX) or improve roughness by mechanical means.
• Do not apply on clay or on paint.

Instructions for use

MANUAL APPLICATION

• Add water and mix by hand or mechanically until it takes on an even and workable consistency.
• Spread the mixed product over the substrate with the use of a trowel.
• The mixture must be extended with a thickness of 15 and 20 mm.
• It is advisable to apply a well compacted first layer of 2-3 mm to seal the substrate, and then spread the remaining material.
• Once hardening begins trowel the material with a wood or plastic trowel.

MECHANICAL APPLICATION

• It is important to maintain constant those variables that may affect the characteristics of the applied mortar (distance from wall, angle of application, and water proportion).
• Fix the optimum proportion water/mortar according to the chosen pump (section and hose length) and external weather conditions. Start with 21% proportion and modify it gradually until you achieve the appropriate consistency.
