ATLAS GTA is a mass manufactured on the basis of resin binders, mineral fillers and modifying additives.

Perfectly white, perfectly smooth – thoroughly selected snow-white mineral fillers of optimum aggregate size allow to form perfectly smooth surface without further corrections.

Optimum consistency for application and top coat shaping – specially adjusted rheological parameters allow effortless application with a trowel, a roller or a plastering unit. Convenient top coat shaping produces smooth surface since the first move of a trowel.

Quick application with a roller – an ideal consistency and prolonged open time enable convenient and quick application with a roller. Top finish can be distributed uniformly without splashing. 

Durable and elastic – elastic polymer bonds ensure high bonding and resistance to cracking of the coated surfaces.

For all types of gypsum filling: PSG1(Q1), PSG2(Q2), PSG3(Q3), PSG4(Q4). For filling joints of plasterboards with the use of reinforcing tapes or for filling of vast surfaces.

Safe application with the “wet on wet” method – reduced time of application and minimised risk of blistering.

“On wet” surface sanding – sanding wet surfaces produces perfectly smooth surface without dust, enables quick and clean progress of refurbishment works.

For manual and machine sanding – top coat hardness enables easy surface treatment, both mechanical and manual.
Substrate preparation
The substrate should be:
• sufficiently sound, stabilized to the air-dry state  - the assumed stabilization time for substrates is respectively:
- 1 week for each 1 cm of the layer thickness for freshly applied gypsum plasters (e.g. ATLAS SOLARIS), cement and cement-lime plasters,
- 28 days for concrete walls and ceilings,
Data above is applicable for standard conditions (+20⁰C and 55% RH). At different conditions, the values may be different.
• cleaned of any materials which would impair bonding of the top coat, especially of dust, dirt, lime, oil, fats, wax, residues of paint coats and anti-adhesion agents,
• primed:
- with ATLAS GRUNTOWNIK or ATLAS UNI-GRUNT emulsion – in the case of excessively absorptive substrates,
- with ATLAS GRUNTO-PLAST contact coat– when the substrate is of low absorptiveness or is characterized by a smooth surface (e.g. concrete ceilings and walls)
 
Mass preparation
The mass is ready-to-use in the case of manual application. While applying the mass with a roller or a plastering unit it is allowed to dilute it with clean water in the amount of max. 2%. The mass should be stirred before use. Use mixers which does not cause the mass aeration.
 
Top coat application
Application with a roller
The mass should be applied with a roller of a minimum 11 mm fleece. It should be uniformly distributed over the substrate. The applied coat should be smoothened with a stainless steel trowel no later than 5 minutes since the application.
 
Application with a trowel
The mass should be uniformly applied with a stainless steel trowel by pressing against the substrate. Do not apply coats of thickness greater than listed.
 
Application of the subsequent coats
·  “wet on wet” – the next coat can be applied upon the initially set previous layer – the mass surface should be matt and touch-dry - usually approx. 2 hours since application (at temperature +20⁰C and 55% humidity).
·  “wet on dry” – if the next layer is applied after drying and hardening of the previous layer, it is recommended to slightly moisten the surface with water.
 
Machine application
The following units are recommended for the machine application (the main device filter should be removed).
Sanding
Sanding should be carried out mechanically or manually, with a sandpaper or a net, when the surface gets completely dry.
 
Dust-free surface sanding
A dust-free surface sanding can be carried out after the top coat hardening. The treated surface should be moistened by spraying with water and sanded with circular moves with a trowel with rubber sponge until the surface of desired smoothness is formed.
 
Jointing with tapes
Apply mass directly into the space between adjoining boards, fill it completely. After initial bonding, apply a thin coat of the mass and adhere the reinforcing tape. The tape should be pressed to ensure it adheres precisely, without folds. Apply a thin coat of the mass on the tape and leave to harden. Mass is applicable also for coating heads of screws used for boards fixing.
 
Finishing works
Before start of the finishing works, the top coat surface should be completely dry and cleaned from dust arisen during sanding. Painting and wallpapering should be carried out after the surface priming, carried out in accordance to the recommendations of a paint or a wallpaper manufacturer.
Coverage:
Top coat application: average consumption approx. 1.0 kg of the mass for 1 m2, for a single-coat application, depending on the coat thickness and the substrate quality.
Boards jointing: an average consumption approx. 0.5 kg of the mass for 1 m of plasterboard joints (the consumption depends on the thickness, shape and method of the plasterboard joints shaping).
