In rainy weather, the transportation of paint must be handled with care. If the paint gets wet, it can easily harden and become unusable. When storing paint indoors, make sure to keep it away from windows to prevent exposure to rain or direct sunlight. As flammable materials, paints should be kept in a cool, dry place to avoid potential fire hazards.
Experts say that damp weather has the biggest impact on painters. Putty, paint, and coatings on wooden surfaces are particularly sensitive to humidity. During construction, wall putty must be fully dried before applying the next layer. If you apply paint too soon, moisture can rise to the surface, causing bubbles to form. Dry putty usually appears white, but if it feels damp and looks darker, it may not be fully dry. To help it dry faster, use a thin layer of putty and apply it in multiple coats.
When rolling paint, it's standard to apply two coats of primer and two coats of paint. However, during rainy days, it's advisable to add an extra coat. To check if the paint is dry, feel the surface—it should have a firm film. If the second coat is applied too early, the paint may wrinkle and fail to adhere properly to the wall.
If painting wood on-site, stop work when the air humidity is too high. High humidity can cause the paint to appear milky and obscure the wood grain. It can also lead to a hazy finish, which negatively affects the overall appearance of the project.
Proper planning and attention to weather conditions are essential for achieving a smooth and long-lasting paint job. Always ensure that all materials are stored correctly and that the environment is suitable for painting. By following these guidelines, you can avoid common issues caused by wet or humid conditions.
