| GIPSAR UNI -ENHANCED FORMULA |
|
• ideal spreading upon substrate
• effective paint coverage
• snow-white colour
• product based on natural white gypsum
FOR INTERNAL USE
|
■ ENHANCED FORMULA
Increased hardness – better mass setting and better primer and paint absorption
(enables easy grounding both with sanding paper and wire cloth
Easy spreading over the substrate – due to reduced absorption of water from the mass.
Enables more effective covering with paint – due to enhancement with polymer
additives, it is a perfect substrate for modern paints.
Creates uniform, strong and smooth surface for painting or wallpapering.
■ Use
Recommended for gypsum finishing coats on walls and ceilings.
Fills small cavities in walls and ceilings – can be used for surface repair before the
execution of the finishing coat.
Types of substrates – concrete, aerated concrete, gypsum, cement plasters, cementlime
plasters and gypsum plasters.
Types of finishing layers – paints coating and wallpapers. |
 |
|
Resistant to cracking resulting from contraction during drying.
High water retention – allowing to retain appropriate amount of water in the mix,
necessary for proper setting.
The coat is snow-white in colour – enables effective covering of the surface with
paint and to reduce its consumption. |

The substrate should be:
• stable – sufficiently rigid and sufficiently long stabilized. The assumed stabilizing time
for substrates is, respectively:
− for new cement plasters from ready to use ATLAS rendering mortars, min. 1 week
for each 1 cm of thickness,
− for concrete walls, at least 28 days,
• dry,
• even – maximum layer thickness of GIPSAR UNI is 2 mm,
• cleaned – from layers that can deteriorate the adhesiveness of the mix, especially
dust, dirt, lime, oil, grease, wax, residues of oil and emulsion paints; if the substrate is
covered with biological corrosion, use ATLAS MYKOS to remove it,
• primed
− with ATLAS UNI-GRUNT emulsion – in case of excessive absorbability of the surface
− with ATLAS GRUNTO-PLAST mix – when the substrate is of low absorbability or is
covered with layers limiting the adhesion.
Moreover, all steel elements that may come in contact with the surface finishing mix
must be protected against corrosion. |

Pour the material from the bag into a container with water (for proportions, see Technical
Data section) and mix manually or mechanically (using a drill with a gypsum mixer) until
homogenous and free from lumps. Leave the mix to rest for 5 minutes and then remix.
The ready to use mix must be used up within ca. 1.5 hours.g mix). |

Apply the mix evenly using a stainless steel float and at the same time smooth the
surface as the work progresses. For walls, it is recommended to apply the mix in strips,
starting from the floor towards the ceiling, moving the float upwards. In case of ceilings,
apply the mix in strips starting from the window towards the interior, moving the float
towards yourself.
Sanding
When the mix dries, even out any irregularities using sandpaper or wire cloth. Cover the
resulting irregularities with a thin layer of mix and sand again.
Finishing works
Painting and wallpapering can start when the finishing mix dries. Before painting, prime
the finishing coat with a preparation recommended by paint manufacturer. Before facing
fixing, prime the finishing coat with ATLAS UNI-GRUNT.
Important informationmportant additional information
• The mix must be prepared in clean containers (residues of set gypsum
reduce the setting time of the freshly made gypsum mix).
• The mix must be thicker while filling in defects than for finishing
coat application.
• The finishing coat cannot be applied to surfaces directly exposed
to humidity.
• Do not apply the finishing coat in bathrooms, laundries, or other
premises with relative air humidity exceeding 75% over extended
periods of time.
• During setting, avoid exposing the finishing coat to direct sunlight and
draughts and provide proper ventilation and airing of the rooms.
The above information constitutes basic guidelines for the application
of the product and does not release the user from the obligation
of carrying out works according to engineering principles and OHS
regulations. |

|
| On average 1 kg of the mix is used for 1 m2 for each 1 mm of the layer. |
|
|
| Drill with mixer, plastic container, typical stainless steel tools for plastering, sanding paper or wire cloth. Wash the tools with clean water directly after use. Clean the remainder of the set mix that is difficult to remove with ATLAS SZOP. |
