Ensuring suitable ventilation...
Applying the spray paint outdoors does not present particular problems and is always recommended.
In case the spray must be applied indoors, open doors and windows for air circulation
To avoid dirtying…
In order to avoid dirtying other surfaces with the spray paint, cover the areas not to paint with very wide adhesive tape and newspapers.
A little professional tip: if you have to paint small objects indoors, make a cardboard box closed on 4 sides, introduce the small object inside the cardboard box and spray. You will avoid dirtying other surfaces.
Homogenising the spray…
Before spraying, shake the bottle well for about 2 minutes. For constant homogenisation, we recommend shaking the bottle also during use, occasionally.
Do a preliminary test with the spray
It is a good idea to test your spray application technique on a small area before beginning to paint. Apply the spray paint on a small area, test the compatibility of the paint with the support (especially plastic) and verify if the finish obtained is satisfactory.
Avoid performing the work in a hurry…
Don’t rush to finish the work. Apply 4 light coats instead 2 thick coats. This way you will avoid non-aesthetic paint dripping
To obtain even surfaces…
To obtain an even and well-coated surface, apply the paint with light and crossed coats, waiting 5 minutes between a coat and the next.
Apply the spray at 25-30 cm from the surface to paint
Removing the spray paints…
The spray paints can be removed with Acetone and/r Paint Thinner.
If the applied paint is very old, use a paint stripper.
The painted surface is not perfectly shiny…
The spray paint was sprayed at low temperature and in very humid environments.
Dry the painted surface with a hair drier or place it in a hot environment to eliminate the humidity coat. If the above is not sufficient, remove the paint from the surface and apply new paint in a cool and low-humidity environment.
The painted surface has a very opaque and rough aspect…
The spray paint was applied keeping the bottle too distant from the surface, therefore it did not wet the support enough.
Sand the surface with fine-grain abrasive paper. Apply another paint coat, keeping the correct and suggested distances (25-30 cm).
The paint is not covering…
The bottle was sprayed at cold temperature or at a temperature below 15°C. At low temperature, the propellant contained in the bottle tends to gasify with difficulty, causing uneven coverage.
Warm the bottle by holding it with your hands or placing it in a heated environment in order to bring it to the optimal spray temperature (20-25°C). Spray again.
The painted surface features uncovered areas, grease spots…
Presence of grease, dirt, oil, silicon on the painted surface.
Remove the paint from the surface with solvents or paint strippers. Clean the surface accurately. Sand the surface using fine-grain abrasive paper and paint again.
The painted surface features an orange-peel finish…
The paint was applied with very high thicknesses on hot surfaces.
If the “orange-peel” effect is light, sand the paint with fine-grain abrasive paper.
If the “orange-peel” effect is remarkable, sand the surface with coarse-grain abrasive paper.
Paint again, making sure that the surface is not too hot and spray with light and cross coats.
The painted surface features hallow areas and drippings…
The paint was applied with very high thicknesses or in cold environments.
Let the hollow areas and drippings dry perfectly. Sand with coarse-grain abrasive paper.
Paint again making sure that the environment is not cold and spray with light and cross coats.
The painted surface is creased and lifted…
In general, this defect occurs when the finishing paint is not compatible with the paint below, when the paint solvents are very aggressive or when the drying times suggested for the paint were not respected.
Remove the paint from the surface completely using solvents or paint strippers.
Paint again using only one type of paint and respecting the suggested drying times.
