BUILDING PLASTER is a universal fast-setting plaster intended for construction, plumbing, electrical and heating works. It is suitable for repairing, leveling and correcting uneven walls and ceilings before painting (plaster, masonry, panels, plasterboard, etc.) and for quick fixing of cables, pipes, electrical. sockets, dowels, installation of profiles during interior and exterior renovations.
Gypsum workflow:
The substrate must be solid and cohesive, free of dirt and grease. Clean and moisten the application site with water with a brush or sprayer. Measure 0.25 l of clean water into the plaster bowl and slowly pour in 0.5 kg of plaster. After about 1 min. after drying and soaking, mix the plaster with a spatula into a smooth mass without lumps. The consistency should correspond to a thick porridge. From this moment on, the plaster processing time is approx. 6 minutes Complete curing occurs in approximately 11-13 minutes, depending on the temperature. Use clean containers and tools when processing. Process plaster only at ambient and substrate temperatures above 5 °C. Do not load anchored materials (dowels, etc.) for at least 12 hours.
Physical and mechanical properties of gypsum:
Grey color.
The translated technical data values are average (actual properties may show certain deviations).
Bulk weight 900 ± 200 kg/m3.
Start of setting > 6 minutes.
End of setting < 11 minutes.
Granularity, R=0.2mm < 5%.
Mixing ratio with water per 1 kg of gypsum / 0.5 l of water
Changes in the ratio of gypsum and water will affect the properties of the processed gypsum, especially the setting time and the resulting strength.
Shelf life:
When stored in the original unopened packaging in a dry environment at a temperature of 5-30 °C, the shelf life is 24 months from the filling date indicated on the packaging. By exposing the product to moisture before processing, physical properties may change and reactivity with water may decrease. To protect the product during or before its processing, open or broken packaging must be properly protected from atmospheric moisture.
Safety and Health protection during work:
Do not eat, drink or smoke while working and observe basic hygiene rules. In case of eye contact, rinse thoroughly with water for 10-15 minutes. In case of accidental ingestion, rinse the mouth and drink at least 0.5 l of water.
Disposal of waste and packaging:
Dispose of the unused product or the remains of hardened plaster together with municipal waste.
