When you look at a nice, clean house, you look at a work of a pressure washer. A pressure washer is a machine that gives you a big boost in cleaning home exteriors. It is a specially-designed tool which sprays high-pressured water, cleaning dirt and mildew and making your house perfect again. But don’t be fooled by its superior look – cleaning your house is not something to be taken lightly. It needs time, energy and a lot of preparation. Preparation is the most important thing, because your idea of a perfect house could end up disastrous pretty quickly.
First of all, when you make a decision to buy a pressure washer, you need to research. You must keep in mind that various types of facades withstand various types of pressure washers. This means that different housing materials can take different amounts of pressure.
For example, painted soft-grain wood can withstand no more than a 1500 PSI (pound per square inch) model. Also, a wide spray nozzle may be needed to release the water pressure from one point. Otherwise, you may find holes and faded color on your facade, especially when it comes to extremely vulnerable materials, like stucco.
For stronger surfaces, like vinyl, you can use up to 3,000 PSI. So, when buying a pressure washer, you should pick carefully and accordingly. Some pressure washers have detergent dispensers for a further cleaning solution. Keep in mind that there are some other tools that you need to possess alongside the pressure washer.
You need to have a clean water supply, garden hose, non-phosphate cleaning detergent, scrub brush, plastic coverings and duct tape. A pair of safety glasses should prevent vision-loss from the reflecting dirt. Make a plan and you are ready for action.
Use the plastic coverings to isolate every hole on the surface, as you don’t want accidently to cause mold inside the walls. Also, you must isolate every external light, outlet, electrical meter and other visible cables as well as you can.
It’s best to turn off the main fuse of your house to establish maximum safety. You should know that window screens are no match for high-powered pressure washers. It’s best to avoid the delicate screens. You should remove any kind of flora, too.
Connect your water supply to your machine with a gardening hose. If needed, mix the cleaning detergent and fill the pressure washer’s detergent dispenser. Combine the detergent with water. You are going to need approximately 450 kg of detergent for every 15 liters of water.
Remember to use only detergents intended for pressure washers. When pressure washing with detergent, it’s better to wash from top to bottom. That way the detergent will have more time to do its magic.
Look ahead for any ground instabilities when putting up a ladder to reach higher spots. Clean is good but safety is a priority. Be aware that you need to hold the ladder with one hand and spray with the other. This is the number one cause why pressure washing is considered extremely risky by insurance companies.
Use the brush to manually remove any dirt and mildew from the surface if reachable. Before starting, you should check the pressure washer’s impact on the wall. Test a small section on the wall that you’ve already cleaned.
Try various distances and select the optimal one. The dirt shouldn’t stay and the paint shouldn’t suffer. For the best results, keep the washer on a 75-degree angle for walls and a 45-degree angle for roof overhangs and underhangs.
Don’t spray directly on corner as the pressure focus grows and at that time these machines are extremely powerful. Start spraying from the top to bottom of the walls, so the dirt will slide down alongside the water and you will leave clean and sparkling walls.
Sometimes you will need to combine it with the brush for more severe mildew and dirt. On some parts of the wall, you may remove the mildew but a green stain will remain. Then you definitely need a cleaning solution of liquid bleach. You should use anti-mildew concentrate. Spray on the area, scrub with the brush, rinse and then wash with the powerful pressure washer machine. It leaves a stainless, remarkable surface. If not, repeat the same procedure.
You should also consider changing the nozzle and experimenting with other varieties. There are three different angles – 15-degrees, 25-degrees and a 40-degree nozzle. There is also a 0-degree nozzle for more heavily-stained surfaces. This is clearly not a nozzle to play with because the water comes out straight, causing a reckless, harmful effect. Use it only to remove massive quantities of dirt.
If you possess a gas-powered pressure washer, make sure that your machine is filled up correctly while working. Expel any excessive air from the hose by pulling the washer’s trigger. You should see the excessive air coming out in the form of steam.
One of the most important things you should practice is to squeeze the trigger to its maximum, so the pump will suffer no harm. You also have to make a consistent side-to-side motion with the hose. That way you put pressure to every part of the facade equally, so no damage will be done.
Pay close attention to all of your future sections on the wall so there is no error that can cause problems
If you plan to repaint your house, pressure washing is a must. Every inch of the wall must be perfectly clean. After you are done, it is best to give the house some time to properly dry out. Usually, this is about two days so the house can be ready for its new skin.
Pressure washers do tend to save water. They can be incredibly effective and efficient. But the coefficient of effectiveness is mostly determined by you. Choosing the correct machine and using it responsibly increases the probability of ending up with a nice, clean, perfect house; just as though it was newly-built.
