Technical Caracteristics

Product based on special cements, synthetic resins, and silica fume.

Advantages and Uses

• R3 class repair mortar according to EN-1504-3.
• Excellent adhesion.
• Excellent reshaping properties.
• Particularly good compatibility with concrete. 
• It is water and weather resistant.
• Repair and levelling of damaged surfaces of concrete on structures, pillars, or façades.
• Surface and cosmetic repair of prefabricated pieces of all kinds.
• Sealing of pores for concrete or mortar substrates.
• Levelling of concrete surfaces.
• Fine renders on concrete, masonry walls, mortars.

Suitable Substrates

• Substrates must be resistant enough, stable, sound, and clean. Free of dust, release agents, organic products, etc.
• Absorbent substrates will be previously moistened until saturation, avoiding puddles.

Application Procedure

Mixing the mortar:

• Add 2/3 of water and progressively add the powder while stirring. Then add the rest of the water and mix for two more minutes. Do not prepare more material than the one to be used in 30 minutes (at +2ºC).

Application:

• Apply 2 to 5 mm thick coats of MORCEMREST C 5 with a trowel or spatula. Let it rest partially, before applying the finish coat.

Curing:

• Protect against wind, sun, and sun during hardening. To prevent excessive drying, it is advisable to cover the surface with damp sackcloth or plastic during the curing process.

Recommendations

• Do not add more water than recommended to the mortar and do not remix.
• Do not apply the product under 5ºC nor above 30ºC temperature.
• Do not add cement, sand, or other substances that may affect the properties of the material.
• The tools and equipment should be cleaned with solvent immediately after use to prevent the material from hardening, which will need to be removed by mechanical means.
• Do not apply more than 5 mm thickness.
• In manual applications, compact strongly between coats; in areas where compacting is difficult, we recommend application using mechanical processes.
• For further information regarding the preparation of concrete or steel reinforcements, please refer to the recommendations provided by standard UNE – EN – 1504 – 10.
