For application of gypsum finishing coats on walls and ceilings.

Fills small gaps in walls and ceilings – can be used for surface repairs before gypsum finish application.

Types of substrates – concrete, aerated concrete; gypsum, cement, cement-lime, gypsum plasters and plasterboards.
Types of finishing coats – painting coats and wallpapers.


The product classified according to the standard as C7 gypsum finishing plaster.

Increased firmness – the strength of intercrystalline bonds in gypsum was increased by the addition of modified polymers - redispersible powder resins - therefore GIPSAR PLUS forms an uniform, firm and smooth surface for painting and wall-papering.

Possibility of machine and manual grinding – after drying the mass can be processed with professional grinders with appropriate sanding discs. Due to the product increased firmness after setting, there is no risk of irregular machine grinding. The finishing coat can also be processed manually, where slight irregularities can be removed by hand with appropriate sand paper or polishing mesh.

Forms strong and stable substrate – the surface can be easily grinded and the resulting dust does not block the mesh or paper.

Possibility of spray application – accelerates the coat application in comparison to traditional methods.

Very good working properties – the mass is plastic, does not form “bubbles”, roll and break during application, is easy to smooth.

Very smooth surface – aesthetic, uniform and smooth, forms excellent surface for painting or wall-papering.

Perfect coating – the addition of polymers makes the surface absorbable for paint coats which makes the finishing works easy and fast.

Resistant to cracking as the result of contraction during setting.


Substrate preparation

The substrate should be:

• stable – sufficiently rigid and sufficiently long stabilized. The assumed stabilizing time for substrates is, respectively :

for new cement plaster made of ready-to-use Atlas plastering mortars, min. 1 week for each 1 cm of thickness,

for walls of concrete, at least 28 days,

• dry,

• even – maximum single coat thickness of GIPSAR PLUS is 3 mm, maximum finishing coat thickness is 5 mm,

• cleaned – from layers that can impair the mass adhesion, particularly dust, dirt, lime, 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 (gypsum plasters and prefabricated gypsum units do not require priming).

with ATLAS GRUNTO-PLAST mass – when the substrate is of low absorbability or is coated with layers limiting the adhesion.

Moreover, all steel elements which may come in contact with the surface finishing coat must be protected against corrosion.

Mass preparation

Pour the material from the bag into a container with water (see Technical Data for proportions), depending on the intended method of the finish application (the mass for machine application should contain the maximum recommended volume of water). Leave the mix for 5 minutes so the gypsum automatically soaks with water. Stir the mix manually or mechanically (using a mixer with a drill for gypsum) until homogenous and free of lumps. The ready to use mix must be used up within approx. 1 hour.

Finish coat application

Apply the mix manually or mechanically. While applying manually, use smooth stainless steel float and successively smooth the surface. Apply the mass onto walls in strips, starting from the floor towards the ceiling, moving the float upwards. In case of ceilings, apply the mass in strips starting from the window towards the interior, moving the float towards yourself. When applying mechanically, spray the mass leading the equipment lance 1-1.5 m from the substrate, in horizontal overlapping strips. Recommended nozzle – HDA651. In case of brakes over 1 hour long, the hopper and coils must be thoroughly cleaned and rinsed with clean water. Level the finishing coat using a steel trowel immediately after spraying. In both cases, the thickness of a single layer should not exceed 3 mm.


After drying the mass can be grinded with professional grinders with appropriate sanding discs. The finishing coat can also be processed manually, where slight irregularities can be removed by hand with appropriate sand paper or polishing mesh. Any irregularities should be floated with a thin coat again (onto previously wetted substrate) and grinded.

Finishing works

Painting and wallpapering can start when the finishing coat dries. Acrylic paints (e.g. ATLAS ecoFARBA) or latex paints (e.g. ATLAS optiFARBA or ATLAS proFARBA) can be used. Before painting, prime the finishing coat with a primer recommended by the paint manufacturer, e.g. ATLAS BASE COAT PAINT.
