Steps To Paint The Exterior Walls

How is 15 ° measured? You can take the following rule as a reference: put your feet against the bottom of the ladder and stretch your arms to measure the angle between the ladder and the wall. If the ladder is at the correct angle, the steps should be horizontal.

Choose the paint

Acrylic (water-based) paint is the best choice for exterior walls. This type of paint helps to waterproof the walls and, at the same time, allows the existing moisture on the wall to evaporate. Before painting an exterior wall, remove as many obstacles as you can (shutters, plants, vines, etc.). Also, go over the grout of the brick walls and remove any dowels, screws, nails, and other items you may find.

Repair cracks and grouts in brick walls

If you are painting an old brick wall, the grout may be cracked or even missing. In such a case, you will have to repair before you start painting. You will need to remove the damaged areas, re-grout, and repair cracks and other problems.

Saltpeter deposits

If you are going to paint a new wall, you may very well see white saltpeter and deposits on it. This is because sometimes, on new walls, after the moisture has dried, traces of saltpeter remain. You can clean the area in question with a wire brush or using a Multi-Cleaner with a cleaning brush. Once this is done, remove any loose dust with a soft brush. Note: once the walls are clean and dry, prevent them from picking up moisture again. And avoid using a high-pressure washer (with water, the process would start again).

Clean the wall

Always start working with a clean wall. If the wall is sensitive to water or if you live in a wooded environment, there will almost certainly be moss and algae. You can remove them with a wire brush and a cutter. Next, treat the wall with 50% diluted bleach. Let it affect for a few hours and then rinse with plenty of water. Make sure the wall is dry before you start painting (it will take a few days).

High-pressure pressure washer

If you use a high-pressure washer, you will remove much of the dirt from the wall. You will also be able to remove loose paint and possible pieces of debris. If necessary, you can apply an anti-moss product, let it take effect, and then clean the wall again. Once this is done, wait about 14 days before starting the painting (the exact time will depend on the weather conditions).

Capillarity

If you have a moisture problem on the walls, you should fix it before you start painting. This may be because good insulation was not applied between the foundation and the wall at the time. In this case, you can open a ventilation opening (for example, a vertical gap in the joints), or you can remove a brick and replace it with a ventilation grille.

Powdery surface walls

If a wall has already been painted previously, it may be affected by dust deposits. This will hinder adherence to the new paint layer. The underlying surface will have to be treated with a special primer. Having a very firm surface is essential; otherwise, the paint coat will not adhere properly and could peel off in no time.

Create a plinth at the base of the wall

You should brush the bottom of the wall, at ground level, to remove dirt and sand and prevent the brush from getting dirty. If possible, dig around the wall to a depth roughly equivalent to the height of a brick, clean the sand, and allow to dry thoroughly. First, apply a base coat to untreated bricks and allow them to dry for at least 12 hours. If you highlight this plinth by painting it in a darker color, the mud spots will not be as evident.

Tape window and door frames

Cover nearby plants and bushes with plastic. Cover door and window frames and other wood elements with bodybuilder tape. Paint the wall edges first with a large paintbrush, then the parts around the door and window frames and gutters. Make sure

there is a good overlap on all surfaces and always paint from dry areas to the edges of wet paint.

  1. Don't skimp on paint - if you don't use enough, the result will be uneven and patchy.
  2. See the lot numbers of the paint you use. If you buy cans from different lots, you may notice color differences, whether you use the paint immediately or store it for a long time.

Spread the paint

Use a long hair roller to paint. This will make overlaps less visible, and you can work much faster. Make sure the roller is well loaded with paint. Apply a vertical strip of paint. Load the roller with more paint and apply a second strip at a distance of about 40 cm. Then, moving the roller diagonally, mix the two strips of paint together. Be sure to apply paint to all gaps and grouts. Next, paint from the top to the middle of the wall, and from there to the floor.

Then go to the next vertical section of paint (left or right of the previous one). In smaller areas or near doors or window frames, use a narrower roller. Keep in mind that there should always be a wet edge, and you should always work from dry to wet areas.

Ladder or scaffolding

To paint, always choose a dry and windless day. Use a good ladder or stool. You should give it about a meter of additional height. To prevent falls, make sure the ladder rests on a stable surface and supports its weight well.

Place the ladder at an angle of about 15 ° to the wall. If a time comes when, while working, you need to get to a point farther than your outstretched arm allows, move the ladder.

Spacers

Spacers give the ladder stability and greater safety when working. Any ladder supports a spacer, which is a very useful accessory, for example, for working with hanging gutters. Spacers usually increase the distance between the ladder and the wall by about 35 cm. To work more safely, it is best to rent a scaffold or basket crane.

Roof gutters

In many cases, roof gutters and edges will also need maintenance and painting. If you have rented a scaffold or basket crane, you can take the opportunity to check the condition of the gutters and make the necessary repairs.
