Clean dirty walls

Make sure you clean and wash your walls thoroughly, especially if you find grime or dirt on it. Wipe away it all with a moist cloth and let the wall fully dry before painting. A clean wall will ensure the paint sticks easily and has a smooth texture.

Always prime the walls

Primers are the best way to get the most vibrant color (even if you’re using shades of white paint) out of your final coat. A primer is typically white and is great for painting over brightly colored walls. Moreover, skipping primer might lead to a bubbled paint final result.

Use cotton tarps rather than plastic on the floor

Cotton tarps on the ground, rather than plastic, ensure no sticking to your feet. Additionally, paint dries much faster on cotton tarps, so you are less likely to track paint around your house.

Paint the trim first

When it comes to the order of painting things, painting the trim first is the best way to start. The order is to paint the trim, then the ceilings, and finally the walls. This is because if you are already painting the walls, you don’t have to be extremely careful around the trim, and so taping is not needed. The same idea goes for the ceilings. It is okay to get the white paint on the walls and then tape the trim and ceilings when painting the walls. It makes the process easier and more effective.

Mix cans of paint to ensure consistent coloring

Paint color can sometimes vary ever so lightly even if you order the same color for all two, three, or four cans. To avoid any discoloration or discrepancies, you should combine all cans into one large container and mix thoroughly. This will ensure that your paint color remains consistent along every wall.

Utilize painter’s tape

A standard painter’s tape is a painter’s best friend. This thin, blue tape easily adheres to walls or trim, and it can be removed without leaving any residue or marks behind. This tape is great for taping trim and any other wall features to avoid getting paint on them.

Avoid lap marks by rolling the full height of the wall, keeping a wet edge

To ensure a clean, uniform look, it is important to focus on your rolling technique. The best way to get a wall with no dried lap marks is to roll the full height of the wall. By doing so, you will ensure the paint is dispersed evenly and there are no random marks going in different directions. Before you start rolling, however, make sure you have a fresh coat of paint along the edges near the floor and ceiling. This painted edge should be wide enough so the roller doesn’t have to get too close to the floor or ceiling. Paint the edge in small sections so that it remains wet long enough for you to connect it with the roller. This will ensure a consistent, clean look.

Get cool designs with painter’s tape

Painter’s tape can be the perfect way to add cool designs to your wall. You can tape letters, geometric designs, or straight lines onto your walls for fun, added features. Tape on your kids’ initials or design a bright, vibrant feature wall. This type of project only requires tape and your favorite colored paint. It is easy to do and can create a fun design on any wall.

Let the paint dry before tape removal

After you tape everything, paint and let the walls draw; the final step is removing the blue painter’s tape. It is important to let the paint fully and completely dry before removing it. This will ensure a clean, crisp line and no smudging. Additionally, you can use a small knife or sharp edge to cut along the tape and paint edge to achieve a super-clean line.

Can you paint in high humidity? What you need to know
Make sure your paint job is still gorgeous when conditions aren't ideal

Are you planning a painting project but worried about the moisture in the air and how it will impact your paint job? If you're concerned about humidity levels while you paint, you've come to the right place. Since paint needs to dry properly to have a beautiful and smooth-looking result, humidity is certainly an issue. So, is painting in humid weather possible? While the answer to that question is yes, we'll discuss some of the concerns and tips for dealing with humidity and painting indoors or outdoors.
How does humidity affect your paint job?

Moisture in the air means there's moisture on the surface you're about to paint. A damp surface is not ideal for painting, and you may find that your overall result doesn't look as great as you'd hoped. Let's dig into the specifics of how high humidity negatively impacts your paint job.
Moisture could lead to mold growth
When you're dealing with high humidity, surfaces tend to dry slowly. When you're painting indoors, for example, you always want to wash your walls before slapping down a coat of paint, so high humidity could slow down the drying process. If your walls are damp when you start to paint, this could lead to mold growing between the wall and the paint. The mold will eventually grow through the new layer of paint, and you will need to clean the area and paint again.
Paint will struggle to dry
For most paint types to dry, the water in the paint needs to evaporate faster than the solvents. In high humidity, the water struggles to evaporate, making for a gunky, gel-like layer of paint. Eventually, when the humidity level falls, you'll find that this type of consistency will dry with a wavy texture since it has not been set properly. You likely won't be satisfied with the result.
Wood surfaces could swell
As you may know, moisture on wood causes it to swell. If you're painting wood when there's a lot of moisture in the air, the wood could start to swell a bit after you've put on a coat of paint. This swelling could cause cracks or chips in your coat of paint, which will eventually lead to the surface needing to be repainted.
Paint may not adhere to metal surfaces
Painting metal objects can already be difficult since paint doesn't adhere to them as easily as it does to wood or other materials. Humidity can worsen this effect, so if you're trying to paint something metal, it might be best to leave that for a drier day.
