Uniflex grey plaster, construction, 3 kg

CONSTRUCTION PLASTER is a universal quick-setting plaster intended for construction, plumbing, electrical, and heating work. It is suitable for repairs, leveling, and patching uneven walls and ceilings before painting (plaster, masonry, panels, drywall, etc.) and for quick fixing of cables, pipes, electrical outlets, plugs, installation of profiles during renovations in both interior and exterior.

Procedure for working with plaster:

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

Physical and mechanical properties of the plaster:

• Color: grey.
• The stated values of technical data are average (actual properties may exhibit certain deviations).
• Bulk density 900 ± 200 kg/m³.
• Beginning of setting > 6 minutes.
• End of setting < 11 minutes.
• Granulation, R=0.2mm < 5 %.
• Mixing ratio with water for 1 kg of plaster / 0.5 l of water.
• Changes in the ratio of plaster and water will affect the properties of the processed plaster, particularly the setting time and resulting strength.

Storage stability:
When stored in original unopened containers in a dry environment at temperatures of 5–30 °C, the shelf life is 24 months from the filling date indicated on the packaging. Exposure to moisture before processing can lead to changes in physical properties and reduced reactivity with water. To protect the product during or prior to processing, opened or damaged containers must be properly protected from moisture.

Health and safety at work:
Do not eat, drink, smoke, and observe basic hygiene rules while working. In case of eye contact, rinse thoroughly with water for 10–15 minutes. If accidentally ingested, rinse mouth and drink at least 0.5 l of water.

Disposal of waste and packaging:
Dispose of unused product or scraps of hardened plaster with municipal waste.

About the manufacturer:
