Whether you are painting your house or simply cleaning it, you will want to make sure that your walls are free of dirt and dust. In this article, we will look at a few ways to clean the exterior walls before you paint. This will help ensure that the new coat of paint will not have any nasty stains on it.
Cleaning a house's exterior
Cleaning exterior walls before painting is an important part of the painting process. It helps remove dirt, mildew, and other debris before you paint, ensuring that your new paint adheres properly.
The first step is to pressure wash the surface of the wall. You can use a power washer or a garden hose with a spray attachment. If you are using a power washer, you should make sure to set the pressure to a low level. Using a high-pressure power washer can actually rip your coating off the wall.
Once you have cleaned the surface, you will need to dry it off. This may take a while, depending on the weather. However, it is worth the extra time to ensure the best painting job.
You can start by removing the old chipped paint. You can also check the siding for cracks and gaps. Make sure that you remove any mildew and mould. If there are any, clean them with a bleach mixture and water. Allow the mixture to dry completely before you start painting.
If you aren't comfortable with a pressure washer, you can hand scrub the exterior of your house. This is the less risky option, but it takes more effort and requires a ladder.
Depending on the type of siding you have, you will need a different cleaning method. For example, brick and stone siding will require a nylon wire brush. If you have vinyl siding, you will probably only need a pressure washer.
Regardless of the type of house you have, cleaning the exterior is an important step. It will not only help the paint adhere better, it will make it last longer. In addition, it will help avoid future repainting.
Whether you are cleaning your home on your own or hiring a contractor, it is important to prepare the outside of your home before painting. Using the right materials and access equipment will ensure that you get the best results. Getting the right preparation will make the difference between a good looking finish and a horrible one.
Applying primer coat
If you're painting an exterior wall, you will want to apply a primer coat before starting your project. Not only will primer protect your walls from future weather conditions, but it will also help ensure the paint is stuck on properly. A fresh coat of primer will also keep stains, blotches, and other flaws from revealing themselves.
There are several different types of primers, and the type you need depends on the wall you're painting. Water-based primers are a good choice for new or porous walls. They give you a very flexible finish and can be used on almost any surface, including bare wood. Some water-based primers also provide excellent crack resistance.
Oil-based primers need to be thinned with mineral spirit. This helps prevent mold from forming. It also provides a strong bond between the wall and the primer. You should also wear a mask to apply this type of primer.
When you're priming a wall, you should also prepare the substrate. This means sanding off any loose paint and protecting any furniture or plants nearby.
While bare drywall can be painted without the use of a primer, if the drywall is previously painted with latex, you will likely need to apply a layer of primer. The drywall needs to be smooth so that the paint will have an even coverage.
Whether you are painting your exterior brick or stone walls, or even shiplap, you should consider applying a layer of primer. The primer will not only hide any darker colors that you have, but it will also create a smooth surface that your top coat will adhere to.
You can find exterior primer in white, grey, and other neutral shades. You may need to use two or more coats of primer depending on the color of the wall. For instance, if you're painting a bold red, you'll need to use a stain-blocking primer to stop water, smoke, and grease stains from bleeding through the finish coat.
Once you've finished, you can add a coat of sealer to your primer. Your finished wall will be resistant to weather and moisture, and you'll have a durable, glossy finish.
Power washing vs hand cleaning
If you're considering painting the exterior of your home, power washing may be a good idea. It's a quick and efficient way to clean the outside of your home, and it also helps protect the paint.
A dirty exterior can damage your home over the long term. This can affect the value of your home, but a new coat of paint can improve your curb appeal. Plus, a clean exterior makes a great first impression. Even if you're not planning to sell your house, a well-maintained exterior will help increase the value of your property.
Power washing is the most effective method of cleaning the exterior of your home. By removing the dirt, grime, and mildew from the exterior walls of your house, you'll be able to prepare it for new paint. Whether you're adding a fresh coat of paint or you're just preparing to put on a new siding or roof, a few hours of power washing will do wonders.
Before you get started, make sure you have all the right tools. You'll need a pressure washer, a hose, and a stiff-bristled brush.
While you're power washing, be sure to wear protective eyewear. You don't want to accidentally hit your eyes with detergent. Also, be sure to keep your windows closed to prevent water intrusion.
In addition to cleaning the exterior of your home, power washing can also remove black streaks, spiders, cobwebs, and algae. The process is easy and efficient, and can boost your home's curb appeal.
However, if you're not interested in spending the time or energy on this project, you can call a professional to do it for you. Make sure they're insured and reputable. They'll have the proper training and equipment. And, they'll know which cleaning products to use to get the job done.
Of course, if you're not a fan of power washing, there are other ways to clean your home's exterior. For example, you can use a soft washing method, which involves wiping the surface of the exterior with a cloth or brush. That will certainly get rid of dust and dirt, but it won't clean the wall as effectively.
Avoiding direct sunlight
If you're cleaning exterior walls before painting, it's important to avoid direct sunlight. This can cause bubbles in the paint's finish and a lack of adhesion on the surface. In addition, the sun's rays can damage the pigments in your paint. These fading effects are most noticeable in dark or brightly colored paints. And, if you're not careful, the sun can even harm your family heirlooms.
The reason direct sunlight causes problems is because the high temperature from the sun can ruin coatings immediately. That's why professional painters always avoid the sun. They also keep their blinds closed when the sun is at its strongest. However, if you can't keep your blinds closed, you can use UV proof glass or UV filtering blinds.
Moreover, direct sunlight can damage the durability of oil paints. It can deteriorate plastic, warp boards, and darken stained wood. Plus, the paint may take on a chalky, faded appearance. Therefore, it's best to start your project on the shaded side of the house.
Finally, you'll need to make sure you get a high quality exterior paint. Ideally, you should get an exterior paint with superior color-fastness. Direct sunlight will weaken the bond between the paint and the surface, causing the paint to peel and chip off. Fortunately, a few different exterior stains offer UV protection. You can also try using a protective film on your windows.
It's best to get the job done in the spring and summer, when the weather is ideally conducive to exterior painting. But you can always protect the paint and other exterior surfaces from the sun with these tips. Whether you're painting a porch or a deck, taking these precautions will help you get the best results. Keep your paints out of the sun and you'll be assured that they'll last. Aside from that, the sun's rays can also damage family heirlooms and artwork, so it's better to keep them out of the sun as well.
