ZAPRAWA ZTM-019 S - standard machine plaster is used for machine or manual execution of single- and multi-layer plaster coatings, both outside and inside buildings. It can be used directly on masonry walls made of aerated concrete blocks, ceramic elements, lime-sand elements and on concrete substrates. It is also suitable for making base plasters under stucco. After mixing with water, it creates a homogeneous plaster mass with very high adhesion to the substrate.
- Very high adhesion to the surface,
- Low water absorption,
- High durability,
- Long application time,
- Easy to use,
- Very efficient,
ZAPRAWA ZTM-019 S - standard machine plaster is produced on the basis of cement and high-quality minerals, it is very convenient, easy to use and very efficient.

SUBSTRATE PREPARATION:
It is recommended to apply plaster after the period of settling, shrinkage and drying of the walls or shrinkage of walls and other concrete elements, such as:
- after at least 2-3 months in the case of brick walls,
- at least 4-6 months after the construction of walls and concrete elements,
The substrates should be durable, stiff, not changing dimensions, and even to avoid places of excessive plaster thickening. Plastered surfaces should be free from dust, soot, fats, grease, organic agents, paints, etc.
The dry substrate should be wetted with clean water immediately before plastering:
- wet brick walls with moderately clean water,
- wet concrete walls abundantly with clean water,
- wet highly absorbent substrates, aerated concrete and aerated concrete, with moderately clean water,
On highly and moderately absorbent substrates, it is recommended to apply a cement coat (spray) or prime them with AKRYL GRUNT GRUNTEX. When plastering walls made of various materials, a cement coating should be performed.
MORTAR PREPARATION:
The dry mixture should be mixed in approximately 6 liters of clean, cool water, mixing in a plastering machine or mechanically using a concrete mixer. The mechanical mixing time should be 2-3 minutes. After mixing the first batch of mortar, check its consistency and correct the amount of water added. The established mixing ratio with water should be recorded so that subsequent batches of mortar are prepared in the same way.
Do not mix the hardened mortar with water or mix it with fresh material.
HOW TO USE:
The mortar should be applied evenly over the entire plastered surface and leveled with a patch. When applying a single layer of 10 mm - 25 mm plaster, the final leveling and troweling with a plastic, metal or felt trowel should be performed after the plaster has started to set.
- on primed substrates after about 4 hours,
- in a piping bag after about 6 hours,
When applying several layers of mortar, apply the next layer after the previous layer has set after approximately 24 hours to increase adhesion. All plastering works should be carried out in dry weather, with little sunlight and little wind. If it is necessary to carry out work in unfavorable conditions, appropriate covers should be used to limit the influence of weather conditions. If necessary, the plaster should be moistened with clean water from time to time.
No foreign admixtures may be added to the mortar, and only clean water may be used for mixing. The mixture must not be sieved, enriched with other ingredients or used at temperatures lower than +5°C or higher than +28°C. If necessary, moisten the plaster with clean water and do not allow it to dry too quickly. Ventilate the room and prevent drafts.
