1. What you will need?
For the application you will need:
- Protective clothing,
- Protective foil,
- Brush, roller, trowel or painting unit,
- GoTherm paint or mass.
2. How to prepare the surface?
- The painted surface should be leveled.
- The surface should be cleaned of free fractions.
- Depending on the condition of the surface (absorbency and stability), it may be necessary to prime it in advance (we recommend GoTherm primer for this).
Do not apply on wet, oily, corroded or moldy surfaces.
3. How to prepare the product?
Before application, the product must be thoroughly mixed (both in liquid form and in the form of a dense mass) – we use low-speed agitators with a maximum speed of 200 revolutions per minute.
Depending on the method of application, it may be necessary to dilute the product.
3.1. Dilution of thermal insulation paint
If necessary , the product in the paint version can be diluted with GoTherm primer:
- about 5% (50ml per 1 liter of paint) – preparation of paint for application with a brush, roller and spray.
- from 5% to a maximum of 25% (50-250ml per 1 liter of paint) – for painting the first layers on surfaces with high temperatures (from 60°C to 180°C).
3.2. Dilution of thermal insulation mass
If necessary , the product in the mass version can be diluted with GoTherm primer:
- about 5% (50ml per 1 liter of mass) – preparation of the mass for putty
- about 10 – 15% (100-150ml per 1 liter of mass) – preparation of the mass for application with a brush or spray.
- from 15% to a maximum of 40% (150-400ml per 1 liter of weight) – for painting the first layers on surfaces with high temperatures (from 60°C to 180°C).
Add the primer gradually with small portions, stirring constantly until the desired consistency is obtained.
Only the amount of the product that will be used within 3-5 hours should be diluted. Adding too much soil can cause delamination and spoilage of the product.
4. Application tools:
Application with a brush is suitable for paint and thermal insulation mass.
For simple painting works that do not require a large aesthetics of surface finishing, a painting propeller can be used. This method is characterized by low material losses and allows for quick implementation, which is why it is suitable, m.in, for steel pipes. It should be taken into account that the application with a brush leaves traces of bristles.
Roller application is suitable only for thermal insulation paint.
We recommend using nylon rollers with short bristles (6mm) or velour rollers (tools are available on our online store). The application with the help of a roller leaves textured finish.
- It is necessary to soak the roller abundantly with paint.
- The first layer is a primer layer (it will pierce the original surface) and will provide good adhesion for subsequent layers.
- Single painting with a roller allows you to apply a layer with a thickness of about 0.5mm.
4.3. Aggregate/paint gun
Spray application is suitable for paint and thermal insulation mass.
The painting unit will work well when painting large areas, as well as those with a complex shape (e.g. details of historic architecture). Spray application allows you to get a delicate textured finish.
No professional painting unit is needed for application using this method – all you need is an HVLP/LVLP paint gun (low-pressure with a maximum pressure of 3 bar) equipped with a 2 to 3mm nozzle and a source of compressed air.
Important! When working with an aggregate, all paint filters should be removed from it or replaced with a filter with a mesh diameter of at least 2mm.
Trowel application is suitable only for thermal insulation mass.
This is a method that requires more practice from the applicant. With careless workmanship, large irregularities may arise, which will require excessive grinding. Grinding damages the coating and reduces its insulation parameters.
Application with putty allows for a smooth surface finish (depending on the skills of the applicant).
Step by step:
- Before painting, it is recommended to prepare the surface with GoTherm primer.
- Open the supplied package and mix the entire product thoroughly at low speed (maximum 200 rpm).
- Put the amount of the product planned for use within 3-5 hours in a separate container.
- If the density makes product difficult to apply, dilute the deposited quantity of the product with GoTherm primer (in accordance with clause 4.1 or 4.2) and mix again. If you plan to get a color other than white, this is a good time to add pigments (intended for waterborne paints) to the thermal insulation paint or mass.
- Painting work (instructions for different tools can be found in point 6.).
- The gaps between successive layers are respectively:
- Up to 1 hour – if painting takes place on the substrate at a temperature above 40°C.
- About 3 hours – if painting is carried out at room temperature.
- From 3 to 24 hours – if painting takes place in extremely unfavorable conditions (temperature below 5°C or high ambient humidity).
- 24 hours after applying the last layer, it is possible to cover the product with another decorative paint.
Important! The use of another paint as the last layer will worsen the radiation reflection properties of the GoTherm coating. In this case, we recommend applying a thicker layer to compensate for the deterioration of radiation reflection by the greater thermal resistance of the coating..
- After the work is done, all the tools can be washed with water.
- Unused (and undiluted) product, after tight closure of the package, can be safely stored for up to one year.
Performance and consumption
The efficiency of the material (both paint and thermal insulation mass) results from its volume. About 1 liter of the product on an area of 1 m² allows you to get a layer with a thickness of 1mm.
The recommended consumption depending on the application is 0.5 – 3.0 liters of paint per area of 1 m².
- radiation reflection – the total thickness of the layer min. 0.5 mm (0.5 l/m²),
- mold and fungi on the walls – the total thickness of the layer min. 1 mm (1 l/m²),
- condensation of water vapour – the total thickness of the layer min. 1.5 mm (1 l/m²),
- thermal insulation – the total thickness of the layer min. 1-3 mm (1-3 l/m²),
- hot surface (e.g. pipe) – total layer thickness 1.5-3 mm (1.5-3 l/m²)).
