Uniflex gray plaster, construction, 3 kg

CONSTRUCTION PLASTER represents a universal and fast-setting material for use in construction, heating, electrical installation, and plumbing activities. It is excellent for repairs, smoothing, and fixing unevenness in ceilings and walls before painting (on masonry, plaster, panel structures, drywall, etc.), as well as for the quick attachment of cabling, pipes, electrical outlets, plugs, or installing profiles during indoor and outdoor renovations.

Plaster working procedure:

The substrate must be solid and cohesive, free from dirt and grease. Clean the application area and moisten it with water using a brush or sprayer. Measure 0.25 l of clean water into the plaster mixing bowl and slowly add 0.5 kg of plaster. After about 1 minute of resting and soaking, mix the plaster with a spatula into a smooth paste without lumps. The consistency should resemble thick porridge. From this moment, the working time for the plaster is approximately 6 minutes. Complete curing occurs depending on the temperature in about 11–13 minutes. Use clean containers and tools when processing. Process the plaster only at ambient and substrate temperatures above 5 °C. Do not load anchored materials (plugs, etc.) for at least 12 hours.

Physical and mechanical properties of plaster:

• Color: gray.
• The stated technical data represents average values (real properties may vary to some extent).
• Bulk density 900 ± 200 kg/m³.
• Starting setting time > 6 minutes.
• Ending setting time < 11 minutes.
• Grain size, R=0.2mm < 5 %.
• The mixing ratio with water for 1 kg of plaster / 0.5 l of water.
• Adjusting the water and plaster ratio affects the properties of the prepared mixture, primarily the setting speed and final strength of the material.

Storage:
In the original unopened packaging and in a dry place at temperatures between 5–30 °C, the shelf life is 24 months from the filling date marked on the packaging. Moisture affecting the product before use can cause changes in physical parameters and worsen reactivity with water. To protect the material before or during application, it is necessary to thoroughly shield open or damaged packaging from air humidity.

Health and safety at work:
During work, eating, drinking, and smoking is prohibited, and basic hygiene principles must be followed. In case of contact with eyes, rinse thoroughly with running water for 10–15 minutes. If accidentally ingested, rinse the mouth and drink at least 0.5 l of water.

Disposal of waste and packaging:
Dispose of unused product and hardened plaster residues in regular municipal waste.
