You have just finished spray painting your favourite study table, and now comes the most patient part – the waiting. Even if the surface seems to look dry, that doesn’t mean that it's ready to be touched, handled or used. Spray painting and traditional painting may look the same, but both require different amounts of time to dry off. Spray paint is a convenient choice for painting any type of furniture or everyday objects. So how long should we wait? This blog covers everything you need to know before spray painting different surfaces.
How long does spray paint need to dry?
There is not a universal drying time for every paint job. The spray paint may feel dry to the touch within a few minutes, but the complete drying and spray paint curing time may take longer than that. Spray paint dry time depends on many factors, including temperature, humidity, the surface you are applying it to, and the type of paint, as different spray paints have different drying times. Below is a guide to point out when you can expect the paint to cure on different surfaces.
|
Surface |
Minimum Curing Time |
|
Metal |
15 - 60 mins |
|
Wooden |
20 mins - 2 hrs |
|
Glass |
20 mins - 2 hrs |
|
Plastic |
20 mins - 2 hrs |
|
Masonry Work |
30 mins - 4 hrs |
These are general estimates; refer to the instructions on the products to know the exact curing time.
Spray painting on different surfaces
Metal - Spray paint drying time on metal is quite quick; however, cold temperatures can prevent it from drying faster.
Plastic - Plastic is smooth, and it becomes tricky for the paint to stick to the surface hence a spray paint with good adhesion is the right choice for plastic.
Wooden- Wood is an absorbent material, and it can take the paint to dry a little longer depending on how thickly the paint is applied. Cosmos LAC Wood Varnish is a perfect spray paint choice for painting furniture or for refreshing old varnish on a chair or table.
Glass - Glass is not an absorbent material, so the paint dries quickly here, but the surface of the glass should be well prepared before applying the spray paint.
Concrete - Concrete is an uneven surface, so the spray paint may take time to dry here compared to the smooth surfaces like glass and metal.
Why does the spray paint take time to dry?
You must have noticed that a certain paint job dried quickly compared to the next when using the same product and technique, so why does that happen? The surroundings matter a lot when painting, so here are some factors to keep in mind:
-
Temperature - Warm or mild temperatures help dry the spray paint dry faster compared to cold temperatures.
-
Ventilation - An open area with good air flow speeds up the drying process, while poor air flow and closed rooms generally take longer.
-
Humidity - Humidity brings moisture to the air, which affects the drying of the paint.
-
Surface preparation - The surface must be cleaned properly so that the paint sticks firmly and dries quickly.
-
Thickness of the coat - Thin and even coats of paint dry quicker than thick coats of paint, which can take longer than usual.
-
Type of Paint - Different paints like acrylic, lacquer, enamel or bespoke paints require distinct time frames for drying. Cosmos LAC Ral Line is the best acrylic spray paint for DIY projects like painting coffee cups or glass frames.
Dry to touch vs fully cured, what is the difference?
Even if we feel that the paint is dry to the touch, it does not necessarily mean it is completely dry. Think of a wall which is freshly painted; on touching it, it may feel dry but the marks of your fingers appear on it, which means the paint is still wet. Spray paint works on the same principle.
-
Dry to touch - The paint is not wet, but it's still soft and may leave marks.
-
Recoating - The amount of time you should wait before applying the next coat
-
Fully cured - The paint has hardened efficiently and is no longer soft to the touch
How do we know that the paint is dry?
-
It does not feel sticky to touch
-
When you press against it or touch the paint, it does not leave stamps or marks
-
When the surface you painted does not feel soft
-
There are not wet patches
Most spray paints are fully cured after 24 hours. So if you have finished painting a surface, give it ample time to dry before you start using it. Cosmos Paints RAL Colours is an excellent example of quick-drying spray paint that can be used for casual craft projects with clay and paper, as well as for professional use, such as painting on walls or canvases.
