Morcemrest^® Mur R CSII

Technical Caracteristics

Product based on hydraulic binders, selected aggregates, porogenic additives and saline efflorescence inhibitors.

Advantages and Uses

• 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.

Suitable 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.

Application Procedure

• 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.

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

Notas

The information and instructions in this datasheet are based on our current tests and technical knowledge. They are intended as general guidance and do not constitute a binding commitment by PIDILITEPUMA MEA CHEMICALS LLC. It is the sole responsibility of the user to verify, prior to use, that the product is suitable for the intended application and to ensure that it is applied correctly and in accordance with applicable regulations and good industry practice.

PIDILITEPUMA MEA CHEMICALS LLC cannot control how its products are applied on site throughout the entire project and therefore cannot accept responsibility for their application by contractors or other parties involved in the execution of the work. Support visits to the jobsite by our technical staff do not change that. Our responsibility is limited exclusively to defects that can be directly attributed to the supplied products, whether used individually or as part of a system, caused by manufacturing defects.

It is the responsibility of the project designer, site manager, contractor, or other relevant professionals to ensure that the selected products are appropriate for the specific project, taking into account their properties, the substrate, site conditions, and any existing issues.

In the event of a claim, the original packaging must be provided to ensure proper product traceability.

Any performance values stated for PIDILITEPUMA MEA CHEMICALS LLC products or construction solutions, whether in UNE standards or other applicable standards, are based solely on the specific test conditions defined in those standards (such as substrate type, temperature, and humidity). These values may not apply to situations where products are tested or used under different conditions.
