Interior House Painting While Raining, Yes or No?
                     
Interior Painting While 
Raining
Rain is not a great restriction when painting 
interior walls. As long as the walls are dry 
and the chances of getting wet are zero, 
you can paint. 
Keep in mind that if you leave the windows 
open while interior painting, your walls will 
probably get soaked and this is precisely 
what is harmful to the paint, both due to the 
water and the relative humidity of the 
environment.
How to do Interior Painting during Raining 
Season
Step 1: 
Open all the doors to the room and the doors to the outside, if it is not 
raining too hard. Open all the windows in your home as wide as possible 
without letting water in. Open the windows where you plan on painting and 
secure a box fan in each window with the window frame. This will ensure 
that you have a strong flow of air going through your home.
Step 2: 
Apply a coat of latex primer with a paint roller and allow it to dry. Latex 
paint dries faster than water-based paint and will expose you to fewer 
fumes than oil-based paint.
Step 3: 
Leave your home while the interior painting dries; take children and pets with you. You need to take 
a fresh air break before going back and applying your coat of colored paint. Come back after three 
hours.
Step 4: 
Examine the primer, if it is wet; give the least two hours drying time. If it looks dry, gently apply an 
inconspicuous area with the tip of your finger. If it is dry, you can go on to paint now.
Step 5: 
Apply latex paint with a paint roller. Take breaks every hour to two hours, depending on how you feel 
and how sensitive you are to chemicals. When you have completed a coat, leave your house for a 
fresh air break. 
The paint will take around 48 hours to dry under normal conditions, so it will need at least another 24 
hours to dry in rainy conditions. Keep windows and doors open and fans open while the paint is 
drying.
Do you know how you can paint your house during winter
Is the surface visibly wet at this time?
Even a few drops count as moisture; we do not recommend painting 
the wall with moisture.
If not, when was the last time you were?
Even if the surface does not appear to be wet, it may have some latent 
moisture, which will affect the paint. An exterior wall wet from the rain 
requires approximately 4 hours of drying, and a temperature greater 
than 20°C to be suitable for the application of paint. 
Ideally, you should wait a full day for the surface to dry. Remember 
that even if flat areas are dry, other surfaces may not be, for example, 
sections not directly exposed to sunlight, trim, cracks, and nail holes.
Is the temperature right?
You have to wonder if the outside temperature is below the minimum 
recommended on the paint can since temperature and humidity work together. 
The lower the temperature, the longer it will take for the outer surface to dry.
Exteriors Painting While Raining
As you might expect, the outside area of o ur home is the most critical area to 
consider when it rains or is likely to rain. Many experts recommend not painting 
when the probability of rain is high. Although, if you live in an area prone to rain, 
you will never be able to paint your house if you abandon this task the moment 
the first drop falls.
