Morcemrest® Mur R CSII
Repair mortar for treating rising damp in skirting boards, facilitating the evaporation of water retained in the wall.
Additional information
Composition
Product based on hydraulic conglomerates, selected aggregates, porogenic additives and saline efflorescence inhibitors.
Features and applications
- Sanitation of walls affected by rising damp.
- Prevents the appearance of salt thanks to its high porosity.
- Conservation of walls technically and aesthetically for years in accordance with water-saline content of soil.
- Reduces the appearance of interior condensation and mold.
- High permeability to water vapour. Dehumidifying properties. - Direct application without need to fill with mortar.
- Application on brickwork, natural stone, concrete block and other porous materials.
- Easy application and excellent adhesion to the substrate.
- Suitable for both indoor and outdoor applications.
- Application on the lower part of wall to be sanitised.
Substrates
- Substrates must be resistant, stable, sound and clean, free of dust, demolding agents, organic products, microorganisms, 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.
- At singular points (joints between different materials, welds, pillars...) reinforce the mortar with fibreglass to avoid cracking.
Instructions for use
- Add water (between 4.75 and 5.25 litres for each 25 kilo sack) and mix manually or mechanically for at least 5 minutes until a workable and uniform consistency is obtained.
- Spread the mixed product over the dampened substrate with the assistance of a blade or trowel, do not apply excessive pressure to avoid closing the pore of the paste, and build up to a thickness of 20 mm. The maximum thickness should be 40 mm applied in two coats of 20 mm.
- Create the finish by scraping or trowelling with a wooden trowel (thus keeping the porosity open) once the required consistency has been achieved.
- Only cover with highly breathable materials.
- Compatible with the range of lime mortars; MORCEM ESTUCO or highly breathable mineral paints.
Cautions and recommendations
- Do not apply under 5ºC nor above 30ºC.
- Do not apply when there is a risk of frost, rain, strong wind or direct sunlight, or with the substrate heated.
- Do not apply on plastered or painted surfaces.
- Over substrates in a bad condition or for larger thicknesses it is necessary to reinforce the mortar with meshing (consult the technical service).
- Do not finish MORCEMREST MUR with unbreathable materials (plastic paints, enamels, stone, ceramic...).
- For indoor applications MORCEMREST MUR increases the relative humidity of the atmosphere. Avoid applying in places without ventilation.
- The height of application should be 50 cm above the damp stain.
- According to CTE in the Basic Sanitation document DB - HS 1: Protection against humidity, when the façade is constructed from porous covering, to protect it you must have a skirting board or other material with a suction coefficient lower than 3% in order to protect it from the rising damp and splashes. Minimum 1 cm from the floor.
