If you are about to begin decorating inside or outside your home, changes in the weather can have a huge impact on the quality of your decorating and the success of your paint job. Various types of weather all have an impact on painting, humidity, heat, cool temperatures, rain and wind. It's important that you choose a time of year to decorate that won't affect your painting. Hot and cold temperatures, rain, high humidity and low humidity all have an effect on a decorating job. Other factors can also affect when is the best time for interior painting. For example, solvent-based and oil-based paints, give off nasty fumes and you would want to be able to open all of the windows when using these paints.
If the air is humid, it means that there will be moisture on all your surfaces. This will result in the paint taking a long time to dry.
In low temperatures, paint will thicken and won't dry properly. This could lead to the paint sagging and long runs or creases. It is also more difficult to apply paint in cold temperatures.
In hot temperatures, the paint will dry too quickly which results in bumps and wrinkles in your paintwork. When it dries too fast the paint is not able to bind properly to the surface and so this results in wrinkles, bubbles and blisters in the paint work.
Humidity affects how well paint sticks to surfaces. When there is high humidity the surfaces have moisture and when you try to paint on top of the moisture you get bubbling and peeling paint.
Crackling and blistering paint is not always the result of humidity and heat, it can be caused by paint being applied on a windy day. Paint needs time to dry properly, if you attempt to paint on a windy day, the paint dries too fast and doesn't adhere to the surface properly.
