Morcemdur® RF OC CSIII W2

Composition

Product based on high resistance cement, lime, selected aggregates, special additives, pigments and synthetic resins.

Features and applications

• To be applied directly on the brickwork. No need for a previous plastering.
• To be applied indoors and outdoors.
• Waterproof cladding.
• Permeable to water vapour, allowing the substrate to breathe.
• No cracking.
• Wearing resistant. Fading resistant.
• No paints necessary. Excellent façade finishes in just one application.
• Rough or sponge floated finish.

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

MECHANICAL APPLICATION 

• Fix the optimum proportion water/mortar according to the chosen pump (section and hose length) and external weather conditions. Start with 20% proportion and modify it gradually until you achieve the appropriate consistency.
• It is important to maintain the same variables affecting the features of the applied mortar (distance to the wall, angle of application and water proportion).

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 12-15 mm, after marking the pieces by using PVC splines.
• It is advisable to apply a well compacted first layer of 2-3 mm to seal the substrate, and then spread the remaining material.

FINISH

ROUGHT FINISH

• Once applied, let the material harden partially (4-15 hours), depending on the substrate and weather conditions. Then scrape slightly with the appropriate tool (toothed trowel, saw blade, etc.). Finally, the following day, brush the surface with a soft-bristled brush to eliminate any loose particles.

FLOATED FINISH

• Float the partially hardened mortar, to obtain a degraded colour finish.

Cautions and recommendations

• Do not apply below 5ºC nor above 30ºC.
• Do not apply when there is a risk of frost, rain, strong wind or direct sunlight.
• Due to changes in the raw material, the one-coat mortar tone might slightly vary from one batch to another.
• It is not advisable to apply on horizontal or sloped surfaces.
• For a thickness of over 2 cm, it is advisable to apply the product in two coats.
• The final minimum thickness should be 10 mm.
