You can use a stiff metal wire brush to scrape these irregularities of the wall surface. If you do not follow this step you will be highly disappointed by the paint job. You can remove all these paints by hand too.


3. Clean your walls of residues

If you want your new paint to adhere and stick to your walls very nicely make sure to make your buildings and walls as clean as possible. If your house walls have already some paint you can power wash the entire house. This will ensure that there is no paint or dirt residue left on your walls.

You need to take care of one thing most importantly. Firstly check if your house walls have softwood sliding or not, do not power wash your house if they have softwood siding as it will damage your walls. The best option is hand scrubbing with detergent and water for such soft walls.


4. Sand all the external walls

Sanding is tej process with the help of which you create a mechanical bond with the coats of paint and your walls. If you don’t rough up your walls, your paint job may look good when you see it. But in some time or some years, the paint will start to show all sorts of errors continuously. These issues may arise especially when you are dealing with oil paints.

For the areas where you are going to use special glossy paint, you use another pass of sanding with grit paper to rough up the surface. Hence, this ensures that sanding is a crucial step that you need to execute before the brush hits the exterior walls.


5. Prime all your external walls

Priming is also an important procedure that you need to consider before you start painting the exterior of your house. The process of priming will help the paint to stick to the already painted surfaces properly. If you tend to paint the exterior of your walls without priming them, the paint might come out easily in some time.

Priming the walls is very important if you are dealing with latex paint to paint an oil-based paint wall. In this case, you have two options. You can either use the latex paint based primer or oil-based primer to protect your paint and make it last longer.


6. Caulk the trims

Make sure to fill all the gaps between the house and trim around the doors and windows using an exterior caulk to ensure an even texture. If your house has different or mixed surfaces you can use the caulk to fill the holes where the different materials meet.


7. Protect your doors, windows, and lights

If you are getting your paint job done, you would not like to have stained doors, windows, and light lamps. To avoid such situations you need to cover the doors with some plastic wrap or cloth and your lamps too. This will protect them from getting stained and hence they will be protected all the time.


8. Pet patrol

If you have some pets you also need to think about them as well. As the painting procedure will affect them depending on the duration the painting job is being executed. Especially if you are going with the scraping process. The pets tend to chew on the unwanted things and catch some sort of infection or complications. Keeping them in a safe place will ensure their safety.


9. Use the best type of brushes

Depending on the type of paint that you are going to use to paint your walls it is important to ensure the type of brush. As the wrong brush may leave your jobs painted with uneven texture. If you are dealing with latex paint, you can use a brush made of nylon or polyester blend. For oil-based paints, you can use a natural bristle brush.


10. Pay attention to the temperature

This is a very important step that you need to take care of for the best possible results. For the best results, you can paint on the days with low humidity where the temperature is around 23 and 28 degrees. Make sure your painted walls are not exposed to direct sunlight as they may develop heat blisters immediately.
