Step 1

Make sure that the substrate is dry, firm, solid, free from frail materials, dust, colors, wax and oils. Before the application of the plaster, it is necessary to even and level the walls, to align the edges, on the corners of the openings and the beams, in order to achieve a nice finish without waste. For the above substrate preparation, it is recommended to use the THRAKON materials SHP 205 (thrown plaster) and GHP 210 (basic layer plaster). Leave the basic plaster for at least 3 weeks to dry completely. Then, slightly wet the basic plaster and apply a thin layer of DEC 425 RILLEN. However, it is important that there is no running or standing water. The absorbent as well as the old surfaces are stabilized with the application of the GLX 290 acrylic primer before the thrown plaster, diluted at a ratio of 4 parts water to 1 part primer. The surface is ready for plastering after the primer is completely dry (approximately 2-6 hours).

Step 2

In case you want to plaster with DEC 425 RILLEN surfaces of polystyrene (such as ceilings) the substrate preparation requires: Firstly, the application of the system adhesive-mesh-adhesive directly on the polystyrene using THRAKON materials THC 405. Next, application of the DEC 425 RILLEN plaster at the recommended thickness.

Step 3

In case the leveling of the surface covered with polystyrene (like supports and beams) is also required, this is performed as follows: Firstly apply the system adhesive-mesh-adhesive directly on the polysterene using THRAKON materials THC 405. Then, consecutively apply the thrown plaster SHP 205 and the basic layer plaster GHP 210. Finally, create the surface finish with the DEC 425 RILLEN plaster at the recommended thickness.

Step 4

Using a steel trowel apply uniformly a thin layer of decorative plaster on the entire surface.

Step 5

Even the surface using a rubber float with very slight pressure.

Step 6

Before the plaster gets dry , using the rubber float, press slightly to shape the final surface making circular moves.

Step 7

The decorative plaster provides a final surface with 2.0-3.5 mm thick lines per case, vertical or circular.

Step 8

The plaster must not be soaked after application and the tools must not be wet during the application.

Step 9

The suitable application thickness is: 2.0 mm for 2.0 mm maximum granulometry, 3.5 mm for 3.5 mm maximum granulometry

Step 10

If you use the decorative plaster on small areas (like frames etc.) or arched surfaces (like supports), you can apply it using a hard brush. In this case add more water and a small quantity (1-2 kg per 25 kg bag) of THRAKON GLX 296 additive. Stir the mixture, in order to provide an easily spread paste. In this way, you can apply the decorative plaster in one or two layers. The final style of the surface is performed in the same way. If you desire a great line density, multiply your movements. When DEC 425 RILLEN is completely dry, it is recommended that you coat it with the GLX 294 impermeable surface coating. In doing so, you will be protecting the plaster from future stains while the dirt that deposits on the surfaces will be easily cleaned. If the surface is not levelled and the final result is not the desired after one layer, you can apply a second one after the first is dry enough. Do not apply the plaster on cracks or connections of different structural elements. Do not apply the product on cracks or connections of different structural elements.
