Tips for painting interior walls

First, you should  measure carefully the area you want to paint, as to know exactly the quantity of paint you will be needing. Afterwards decide on the color you want to apply and go to your local diy store. Read carefully the paint label, as to know exactly the covering surface or the time needed to dry out.

Prepare the surface before painting it with washable. Therefore, remove the previous coats of paint using a scraper and different granulations of sandpaper, degrease the surface and repair the wall with putty, if necessary. Apply several coats of primer, as to make sure the washable paint will adhere to the wall. Do not skip this step, otherwise your coat of paint won’t be uniform over the whole surface of the room.

After you have painted the interior walls, you have to install the outlets and light switches back. Next, clean the flooring and remove the dust sheets. Last but not least, move the furniture in its place, making sure you don’t scratch the flooring.

In this image you can see the tools we are going to use when painting the interior walls. Therefore, we need paint rollers of different dimensions and granulation (for rough textures ), a hand sander for removing wall bumps and paper tape to protect different elements of the room from getting dirty with paint. In addition we will use a paint tray.
Remove the curtains and move the heavy furnishing in the middle of the room, making sure you cover them with dust sheets.

The next step is to protect the baseboard trim and other items from getting dirty with paint, by applying paper tape. The paper tape is cheap and it is very useful when having to mask certain items.

Smart Tip: Protect your windows, doors and flooring by using plastic foil and paper tape. In addition, we recommend you to place dust sheets over the whole surface of the floor, otherwise it would be difficult to remove the drips of paint.

 

Sanding the wall before painting

Painting your interior walls represents a great opportunity to smoothen their surface and to remove the blemishes. In addition, you should fill the holes and cracks with drywall compound or putty, by using a small flat trowel. After the compound has dried out, you should even out the surface, by using a sand block and 120-grit sandpaper.

Next, remove the dust and grease from the walls either with a sponge or a clean fabric and an appropriate detergent. Afterwards, vacuum the floor.

Next, you should turn the power off from the electrical panel and remove the outlet and the light switch covers, as to be able to apply the paint coats in a professional manner.

Smart Tip: Cover the inner parts of the outlets and of the light switches with paper tape, as to protect them against getting dirty with drips of paint. Work with patience, as the preparation stage is almost done.

 

Removing the radiator

It is also necessary to remove temporarily the radiator, as to be able to apply the paint coats on the surface behind it. Consequently, you should first turn off both valves and then unscrew the cap-nut at the end of the radiator (the one placed at the bottom of the radiator).

Next place the bowl under the joint, as to prevent water from dripping on your flooring and open slowly the valve to let the water out of the radiator. Wait until there is no water left in the radiator and then remove the other cap-nut. The last step is to lift the radiator from its brackets and drip the rest of the water left in it.

The next step is to apply paper tape along the interior walls, if you want to paint them in two colors. Consequently, use regular paper tape and attach it to the walls, making sure it is level. Nevertheless, if you want a traditional design, you should attach the paper tape around the ceiling edges.

Smart Tip: if you want to make sure the paper tape is horizontal, use a laser level. However, if you don’t have this tool, just use a 6’/150 cm spirit level, which will do the job just fine.

After we have applied the paper tape on the walls, we obtained he following result. Remember that you can choose the height at which you place  the paper tape, or even its shape. It is not mandatory to apply it perfectly straight, it depends according to your tastes and needs.

Smart Tip: for a quality finish, just push the paper tape with you hand, making sure it doesn’t fold and there is no space under it, otherwise the paint coats won’t end in a perfectly straight line.

The first area that you should cover with paint is the one around the door jambs. Therefore, you should apply the paint coat with a small roller, which is designed for this narrow surfaces.

Smart Tip: use a small brush (1-2”/ 2-5 cm) around the door jambs, as to make sure you won’t dirty the wood with paint. Apply the paint in a straight line along the edge, making sure you don’t touch the jamb, or mask it with paper tape.

Next, you should cut in around corners, ceiling and light switches. The best method you could use is to apply the paint with a small brush, as you have more control. Use firm strokes and strive to get straight lines.

Do not apply too much paint at once, and remember to level out any drips or heavy marks of paint, before continuing the process of painting. You should use these techniques around the windows and flooring as well.  In addition, apply the paint coat as uniformly as possible.

After you have finished painting the wall corners and around the ceiling, you should apply the coat of paint on the rest of the surface. Consequently, use a large roller to draw vertical strokes on the wall, until you cover the hole surface. Work with good judgment, and make sure the coat is uniform and there are no visible brush marks on the painted surface. Remember that you don’t need to go too close to the ceiling, as you’ve already covered those areas.

Usually, a single layer of paint is not enough, so you have to apply minimum two coats of paint to get a  proper finish. If the wall is not covered properly with paint, just wait several hours until the first coat fully dries, and then apply a new coat of paint in the same manner.

Smart Tip: when the strokes become nonuniform, it is time to reload your roller. Keep your eyes open, as to avoid the dust or any other particles from coming in the room, otherwise they will damage the finish.

To get the job done quickly and in a professional manner, we recommend you top use a large roller and a paint tray. Make sure you don’t overfill the pad with paint, otherwise it would be difficult to load it on the roller (it should be around 1-3 of the tray’s volume). Role it backward forward into the paint several times and then over the top section of the tray, as to distribute the paint uniformly.

Use vertical moves to paint the surface with the roller. As you can notice in the image, the paint is starting to dry out, therefore you have to move at a decent speed, otherwise the corners will dry before painting the adjacent surface.

Smart Tip: When you complete a section, you have to move the roller in one direction (upward or downward), as to get an even coat over the whole surface, without visible marks.

After you have finished painting the room, you have to check again any uneven marks, drips or other residues caught in the  paint layer. If necessary, use you roller and repair the issue, before the paint dries.

If you are completely sure the paint coat is properly applied, you should proceed to the final step – detaching the paper tape of the wall. Make sure the paint hasn’t dries and detach gently the paper tape, as not to damage the paint edge.

In most of the cases, it will take about a day for your paint to dry out completely, depending of the temperature in the room and the type of paint you have used.

During this period of time, it would be better to ventilate thoroughly the room, but make sure you keep it nice and clean. Therefore, any dust particles or other residues might damage the finish, so pay attention to these aspects.
