1. Preparation of the Application Surface
Objective: To apply Insulate and Uni-finish according to manufacturer recommendations Before the application, the surface must be checked;
Visual control
- All foreign sticky materials, such as dirt, soot, mortar stains, concrete dirt, molding wood wastes
- Loose and spilled parts on concrete surface
- Sticky lime and efflorescence
- Very smooth and tight surfaces
Manual control
- Control of the surface by hand if it is dusty and dirty from different areas
Scraping control
- Check if scaly parts or loose sands are present by spatula or trowel scrap
Wetting control
- After application of water on the surface, checks if water is always present, it may have ome oil on the surface or it may be too humid.
Temperature control
- Check before the application if the environment temperature is less than 45 degree Celsius.
2. Insulate Application
After inspection of the surface and taking necessary precautions one can start the application Insulate. Aluminum liner for the corners, Aluminum liners for the wall thickness, and galvanized steel mesh for the joints are required.
The list of tools are plastic container, mechanical mixer, water gauge, plastic plaster shovel, plaster trowel, aluminum knife template, special plaster sponge, rectangular steel trowel and Spatula.
Before mixing, follow the technical specification of Insulate.
| Technical Specifications for Insulate | |
|---|---|
| Water/Powder Ratio | - 5-6 lt per 10 kg |
| Working time | - 60 minutes |
| End of Setting time | - 120 minutes |
| Consumption | - 10 kg per m2 for 1 cm of thickness |
| Technical Specifications for Uni-Finish | |
|---|---|
| Water/Powder Ratio | - 16,5-17,5 lt per one bag of 25 kg. |
| Working time | - 60 minutes |
| End of Setting time | - 130 minutes |
| Consumption | - 1 kg per m2 for 1 mm of thickness |
The application must be performed according to gypsum standards and gypsum specifications by choosing proper products. DO NOT add water on powder. DO NOT add water more than 75% of the product weight. Use always protective gloves and follow Health and Safety rules.
Mixing
1. Review the checklist at the end of this brochure and the equipment to be used.
2. Insulate bag is cut off by a cutter, and poured into the plaster machine.
3. The machine functions are generally controlled. The amount of water is set
4. The plaster machine is activated; the plaster is poured into a container until to obtain the required consistency.
During this time, the water adjustment is set if necessary.
5. The consistency should be around 170 mm on the flow table according to gypsum standard.
Wall Finishing
1.Insulate is applied to the joint of different material by using galvanized steel mesh.2. Install the corner liners properly on the wall by using the plater in the container.
3. Install thickness liners at every 150-200 mm. Care should be taken that the liners are aligned and water gauged.
4. After the plaster of the liners is hardened, the plaster can be applied on the wall.
5. The plaster is applied from the bottom to top by following parallel lines. The application is continued until the surface is covered with this method. Nature of the surface does no change the form of application. Application is done in the same manner on brick, concrete, gross concrete, aerated concrete, hollow brick etc. surfaces.
7. Excessive plaster on the aluminum knife template will be applied to empty gaps
on the wall surface.
8. After applying a second and/or third knife template the surface is finished.
9. After around 30 minutes from the initial application, the thickness liners are taken away and empty space is filled with mortar by using a trowel.
10. After around 60 minutes from the initial application, the surface is leveled again, and if necessary 2-3 mm of plaster will be applied on the surface in order that it is gauged vertically and horizontally.
Wall Finishing
1. In order to finish the surface more properly, a special Plaster sponge is used after 70 minutes of the initial application. The satin of the gypsum mortar is taken on the surface.
2. Then a rectangular steel trowel is used 5-10 minutes after sponging until a smooth surface is obtaine
Wall Finishing With Uni-Finish
1. If a smoother surface is needed, Uni-Finish is applied.
2. When the surface is dried, Uni-Finish mortar is prepared according to the specifications and application rules and it is applied on the surface by a steel trowel and a spatula.
Ceiling Application
1. It is exactly the same as wall application; it is applied by pressing the special plaster shovel upwards through the ceiling.
2. Uni-Finish should be applied as in the previous section.
Wall Finishing
1. In order to finish the surface more properly, a special Plaster sponge is used after 70 minutes of the initial application. The satin of the gypsum mortar is taken on the surface.
2. Then a rectangular steel trowel is used 5-10 minutes after sponging until a smooth surface is obtaine
Powder & Water Consumption
Objective: To calculate the amount of Insulate and Uni-Finish in a site the specification of INSULATE is as follows;
| Technical Specifications for Insulate | |
|---|---|
| Water/Powder Ratio | - 5-6 lt 10 kg. |
| Working time | - 60 minutes |
| End of Setting time | - 120 minutes |
| Consumption | - 10 kg per m2.cm |
The total area is 5 x 3 = 15 m2
→ The empty areas of the window and the door are (0.9 x 2.1) + (1 x 1.5) = 3.39 m2 the net area is; 15 – 3.39 = 11.61 m2
→ If a thickness of 1 cm will be applied, then;
11.61 x 10 = 116.1 kg of Insulate is needed.
→ If the thickness of plaster is 1.5 cm, the total amount will be calculated as following;
→ 116.1 x 1.5 = 174.15 kg Insulate (5 bags) the total amount of water needed is
5 bags x 5,5 lt/10kg = 96 liters of water
→ It will be the same calculation for Uni-Finish according to its specification
