Under most circumstances, the answer is yes, as long as you are sure your garage walls stay dry despite the rain. … It may even be a great idea, as the rain will keep the dust outside from flying in and sticking to the paint.Apr 23, 2019
You can paint both the exterior and interior of your house when it rains but not with rain touching the painted surface. … For both exterior and interior surfaces, you can expect it to take longer for the paint to dry in the humid conditions of a rainy day than on dry, sunny days.
Rain will wash wet paint off the surface and paint won’t be absorbed into a wet surface. When it is raining outside, the paint will wash away if it isn’t dry. The best way to handle this is to be sure to avoid rainy days. If there is rain forecast for significant parts of the day, plan it for another time.
The best paint for garage walls and ceilings is interior latex paint, though oil-based paints can also be used. … Exterior paints often have toxins that can be harmful if used indoors, even in a well-ventilated room. There are many durable interior brands that are safe options for garage wall paint.
The short answer is no. If you contractor offers options to work in the rain, run. Moisture on the walls and in the paint will ruin a job. Companies have practices where they dry the walls and paint in a downpour.
Rain or snow will affect how the paint adheres to the concrete and how it dries, so choose a time of year when you know you’ll have proper dry time. … If you’re painting a covered outdoor concrete patio, or a garage floor, you can paint if it’s wet out, just make sure water can’t leak onto the slab and ruin your work.
The moisture in the air makes it difficult for paint to dry completely because the water in the paint does not evaporate easily in high humidity. When the paint is applied at lower temperatures in high humidity, condensation can occur on the surface of the paint. … Avoid painting when the humidity is 85% or more.

In a perfect world, you should wait about three to four days afterward before you start exterior painting. This gives typical surfaces like wood, brick, and other porous materials time to fully dry. It’s never a good idea to paint onto still wet surfaces.
Adding a Second Coat
After your first coat of paint is dry, it’s safe to recoat typically after four to six hours. A good rule of thumb is to wait at least three hours to recoat your paint or primer if it’s water-based.
Too cold and the paint may not dry at all. … Water-based paints can be ruined at freezing temperatures so be sure to check the weather report. You want at least 2 consecutive days of good temperatures for painting. High temperatures (over 90° F for oil-based paint and 85° F for water-based paints) also cause problems.
It is recommended that the temperature be be at least 50 degrees Fahrenheit (10 degrees Celsius) and not higher than 90 degrees Fahrenheit (32.2 degrees Celsius) for the entire painting application time and the drying process. Humidity also plays a part too. High humidity has similar effects to high temperatures.
Add all the walls together and the total surface area of the garage to be painted is 672 square feet. If the paint chosen covers 400 square feet, for example, the project would use most of two gallons. Most paints list an expected coverage per gallon; this is an estimate.
Painting the outside of your house is best done in the fall or spring when temperatures are moderate, and the weather isn’t too hot or too cold. The best temperature range for painting outdoors with latex paint is from 50° to 85° F.
I would wait a MINIMUM of one day after a heavy rain, but remember the surface must be dry before painting. Too much moisture in the substrate will prevent absorption and will most likely lead to peeling.
Check for moisture by taping a 2’x2′ piece of 4-mil plastic to the floor with duct tape. If no darkening of the concrete or condensation is evident after 24 hours, the floor is dry enough to paint. The floor should be thoroughly cleaned and acid etched prior to application.
If paint is applied when the concrete is too wet, the paint is not likely to bond well, and the coating will fail. The paint must be removed, and repainting should be scheduled for a drier day.
Paint needs an environment of at least 50 degrees in order to dry properly. It may crack sooner than later if applied in too-cold temperatures. Even if it is 60 degrees during the day, if the temperature dips below 50 degrees at night, the paint structure can be compromised.
It may sound like a bad idea, but done right rainy weather will not affect the quality of painting on your exterior walls. … In rainy weather, the humidity increases when temperature slows down causing problem in drying of paint that is why experts usually suggest waiting instead of painting in rain.
Maximum Humidity: 70- to 85-percent and more
Once humidity levels reach 70-percent, paint begins to dry too slow. Above an 85-percent humidity level, the paint turns gummy and will not solidify.
People frequently do not realize that you can actually damage your concrete driveway, patio, or other concrete areas by pressure washing. … However, using a pressure washer with the incorrect tip or using too much pressure or a combination of the two can etch concrete.
Pressure washing before painting is a chance to remove all dirt, debris, and cobwebs before painting. It’s important to wash your house so that the new coat has the best chance to bond with the undercoat. By cleaning off all the gunk, we can make sure the paint goes on smoothly, not just rolling over dirt.
By leaving the used skin in the paint you are leaving contamination in the bucket that will throw off the color or rot the paint prematurely.
The general rule is that you should use two coats of paint. However, this rule changes based on the color, quality of the paint you use, whether or not you used primer, and the type of surface you’re painting.
Applying the second coat too early will result in streaks, peeling paint, and uneven color. Not only will this ruin the entire project but it’ll cost additional money to get more paint in some occasions. It’s best to wait for the first coat to dry.
