Morcemrest® Mur R CSII
Renovation mortar for the treatment of damp by capillarity on the lower parts of the wall, facilitating the evaporation of water retained in the wall.
Additional information
Composition
Product based on hydraulic binders, selected aggregates, porogenic additives and saline efflorescence inhibitors.
Features and applications
- Sanitation of damaged walls due to rising damp.
- It prevents the appearance of salts on the wall surface thanks to its high porosity.
- Conservation of the wall technically and aesthetically for years depending on the water supply - saline of the soil.
- It reduces de appearance of condensation and mould indoors.
- Very permeable to water vapour.
- It provides dehumidifying properties - Direct application without filling.
- It may be applied on top of bricks, natural stones, concrete blocks or any other kind or porous fabric.
- It is easy to apply and posses an excellent adhesion to the substrate.
- Suitable for indoors and outdoors applications.
- Application in the lower part of the wall to be repair.
Substrates
- Substrates must be resistant, stable and sound.
- They must be clean and free of dust, remains of release agents, organic products, microorganisms, etc.
- In case of heat, wind or very absorbent substrates, it is convenient to moisten the substrate and wait for the water film to disappear.
- At singular points (joints between different materials, floors, columns...) reinforce the mortar with fibreglass mesh to avoid cracking.
Instructions for use
- Add water (between 3.8-4.3 litres for each 25-kilo bag) and mix manually or mechanically for at least 5 minutes until a homogeneous and workable consistency is obtained.
- Spread the mixed product on the moistened substrate with the help of a trowel avoiding too much pressure so not close the paste porous until getting a 20 mm thickness.
- The maximum thickness will be 40 mm applied in two layers of 20 mm.
- Carry out the scraped or floated finish with a wooden trowel (and thus maintain open porosity) once the adequate consistency is obtained.
- Cover only with highly breathable materials.
- Compatible with the range of lime mortars; MORCEM STUCCO or highly breathable mineral paints.
Cautions and recommendations
- Do not apply bellow 5ºC nor above 30ºC.
- Do not apply the product with risk of frost, rain, strong winds, direct sun or hot substrate.
- Do not apply on top of plaster or paint. On poor condition substrates and for large thicknesses, it is necessary to reinforce the mortar with mesh (check with the technical department).
- Do not cover MORCEMREST MUR with materials that are not very breathable (plastic paints, varnishes, stone, ceramic tiles...).
- On indoors applications MORCEMREST MUR increases the relative humidity of the environment. Avoid its application in places without ventilation.
- The application height will be 50 cm above the damp stains.
- According to CTE in the basic document of Health DB - HS 1: It should be protected against humidity; when the façade is made of a porous coating, to protect it, there must be a plinth or other material whose suction coefficient is less than 3% in order to protect it from capillary rises and splashes. Minimum 1 cm from the ground
