Pumablock Mortero adhesivo

Technical Caracteristics

Product formulated with high-strength cement, selected aggregates, and special additives.

Advantages and Uses

• Masonry works of cellular concrete block.
• Thixotropic, easy to apply both horizontally and vertically.
• Permeable to water vapor and impermeable to rain.
• Hardens without significant shrinkage, allowing for perfect adhesion of the blocks.

Suitable Substrates

The construction elements must be dimensionally stable and solid, free from loose parts, dust, oils, and any other substances that could affect adhesion.

Application Procedure

• Add 5-6 liters of water per bag and mix manually or mechanically until a homogeneous and workable consistency is achieved.
• Lift the concrete blocks using special trowels of the same width as the wall. Apply a continuous layer approximately 3 mm thick, place the blocks, and gently tap them with a rubber mallet to ensure proper seating. This method achieves a uniform and continuous layer with a consistent thickness between 1.5 mm and 2 mm.
• To lay the next course of blocks, wait until the adhesive of the previous course has completely dried.
• Before placing each course of blocks, it is essential to verify the perfect leveling of the wall both longitudinally and transversely. If necessary, make corrections by sanding and removing dust and loose parts.
• Next, remove any mortar that oozes from the joints and level these joints as soon as possible.
• The vertical faces of interlocking blocks will not receive Pumablock adhesive mortar. However, a continuous layer of adhesive mortar should be applied at junctions between blocks with smooth faces, at right-angle joints, and at connections between cut blocks.
   

Recommendations

• Do not apply below 5°C or above 30°C.
• Do not apply in the presence of frost, rain, strong winds, or direct sunlight.
• In extreme weather conditions (high wind or high temperatures), drying occurs faster than normal.
• It is important not to mix Pumablock adhesive mortar with plaster, cement, sand or other construction materials.

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.
