How to Pressure Wash A House (w/ Monica from The Weekender)

[upbeat music] – Pressure washing is one of
the most cost-effective and efficient ways to keep your home
looking like new. Built up dirt, grime, mildew, and mold can be removed in a fraction
of the time it would take to scrub it by hand
or just use a garden hose. Today’s goal with pressure washing is actually to prep this house
for a fresh coat of paint. So grab some safety goggles and clothes
that you don’t mind getting a little wet, because I’m gonna walk you through how to pressure wash a house
the right way. I’ll give you all the tools you need, tips, safety precautions, so that by the end of this video, you’re confident
to pressure wash your house and have it looking sparkly
and clean like new. [dynamic music] A pressure washer is a way
to amp up your garden hose. It has a motor that increases
the PSI of the water. If you think of it like cars, your garden hose is kind of like
a 3-cylinder hatchback, and your pressure washer
is a super fast sports car. And speaking of cars, don’t ever use
a power washer to wash your car. A lot of people do that.
It’s a terrible idea. It can really damage the paint. Pressure washers can clean
houses, decks, patios, driveways, sheds. It’s a great tool to have to help with
a variety of uses around the house. I’m gonna show you how to
pressure wash this house the right way and avoid some common mistakes. All right, so we are using
a Craftsman 3200 PSI gas-powered pressure washer
for this project. There’s a lot of different options
out there for pressure washers. They have some really good electric ones,
cordless options, and great gas options as well. For this project and our purposes, we’re going with
the pretty heavy-duty gas-powered. Look at the PSI rating
when choosing a pressure washer. PSI means pounds per square inch. The higher the PSI,
the greater the force of the water. A typical garden hose has about 40 PSI– not strong enough to do
heavy-duty cleaning on your house, but if you take that garden hose
and hook it up to a pressure washer, it can easily increase your PSI
by over 50 times. This model has a PSI rating of 3200, which means it’s about 75 times
more powerful than a typical garden hose. Pressure washers also use up
80% less water than a garden hose– powerful and efficient. So we’re gonna walk through kind of
some of the features and how this bad boy works. – Basically what we have here
is this is where our gas is going to go. – Okay.
– And then we have our on/off switch. And then we also have our choke
for the gas and then the gas fuel line
for turning that on and off. This is an extra added safety feature
that keeps fuel from running through. – Okay. So first thing we need to do
is put some gas in it because we’re working with a gas-powered. – So with a gas-power engine,
you want to be cautious of a few things. One is you don’t want to run out of gas.
– Yes. – If you do, that can cause vapor lock,
and you don’t want that. – No.
– And when this runs, it’s gonna run hot, so you want to make sure that you’re not
refueling it when it’s hot. You want to allow it to cool down. – So in the front of your pressure washer,
there’s gonna be two hose nozzles. We’re gonna be using two hoses
for this project– one is your input hose,
which is your regular garden hose that you already probably have, and the other is our high-powered hose. That’s connected to the pressure washer. It gets connected to the front
and then also here to the wand. So you’re going to put a tip
onto the end of your wand, and each tip has a different purpose,
so it’s really important to make sure you know what each tip does and then know what surface
you’re about to be working on. You’ll want to select the best tip that will clean
without damaging your surface. Test the tips on a section
of your exterior to see what works best. Choosing the right tip for the job
is extremely important. Using too much pressure
can damage the surface and beyond. Pink is the low-pressure
soap detergent nozzle. Use this when applying detergents
for your cleaning projects. White is the 40-degree nozzle.
It’s a wider fan of water, less pressure in direct spots,
best for surfaces that are softer, and more prone to being damaged. Yellow is the 15-degree tip. It’s typically used for surface prep
such as removing dirt, mildew, or paint and can be used on most surfaces. Red is the zero-degree tip.
Be careful with this one. It delivers a very concentrated
stream of water and highest PSI. It could damage softer surfaces. [mellow music] This house is in the middle
of a renovation, so there’s some unpainted surfaces,
missing trim, but luckily, we’re not dealing with
any lead paint. Don’t pressure wash your house
if it’s painted with lead paint, as this can be very hazardous. If your house was painted prior to 1978, or you suspect it might have lead paint, it’s best to let a professional
do an inspection and make recommendations. It’s really important that you know what type of house material
you’re dealing with as it will impact
the way you pressure wash, how much pressure to use,
the tips you use. So, Jon, what do we have on this house? – So we have a block house
foundation here, and then we have wood up at the top.
– Mm-hmm. – We got brick out front,
and we also have vinyl windows, so we’re covering all the bases
with this house. – We’re covering all of it. So all of those are safe
for pressure washing. Now, before you ever start
pressure washing, you want to take a good look
and inspect all the surfaces of the home. We’ve looked around here
and we’ve found a few things that we’re gonna need to take care of. First, there’s a pretty good
rust stain out front, so we’re gonna need to give that
some special attention. There’s a bit of just like
kind of dirt rubbed in. There’s loose dirt and debris. And then there’s also even an area where some vines
have grown up onto the house. Also went around and clipped away
any of the bushes or greens that were up against the house
or just pulled them away. This is an area that can be really
prone to staining, so you want to make sure
that you have full access and can pressure wash there as well. Also really important–
when you’re inspecting your home, look for areas where water
could possibly get in and make sure you protect those. We put plastic around
some of our exterior lights. We wrapped up our doorbell.
We put duct tape over our outlets. Also, when we’re pressure washing,
we’re gonna make sure to avoid any window casings, any caulking areas,
and the edges of doors. We don’t water to get into the interior
of the home and cause some leaks. So now in this area,
we have a lot of exterior utilities, and these are weather-proof. But just to be careful,
we’re not really going to pressure wash anywhere in this area. We don’t really need to wrap
all of these up. They are used to taking the elements. But we’re just gonna steer clear
of all of this area. So this is a serious power tool, and I’m sure you have
some professional safety tips for me. – It may seem simple,
but we gotta be careful because we are dealing with engines, and we are dealing with a wand
that has a lot of PSI to it. So if you think of like a nail gun,
you’re gonna get that same recoil. So you’re definitely gonna want to
make sure you have your eye protection, and you definitely don’t want to
be aiming it at anybody, and you want to be smart. And then the big thing is
is you don’t want to stand on a ladder when you’re using this
just because there is so much recoil. So there’s some ways
that we can resolve that, but we’ll get to that later. – And this isn’t quite as much
about safety, but guys, you’re gonna get wet. This isn’t a business casual type event. Make sure you’re wearing
some old clothes that you don’t mind getting wet. [mellow music] For this house,
it’s gonna be a two-step process. First what we’re gonna do
is use the pressure washer to apply a cleaner, and then we’re gonna come back
with the pressure washer, switch out the tip,
and pressure wash the entire thing. The soap we’re gonna start
from the bottom up, and then for the pressure washer,
we’re gonna start from the top down. How ’bout I attach the hose, you load up a cleaner?
– All right. Deal. – And we’re just using a basic
kind of all-purpose cleaner. This will work really well
in this particular instance because we have a combination of
block, wood, and brick. So it’s very all-purpose. This is actually a plant-safe cleaner, so it’s not really gonna do any damage
to the bushes and trees around the house. But just to be on the safer side, we’re also gonna
spritz them down with water just to make sure that they’re
not absorbing too much of the cleaner from the ground.
– Well, what I’ve done is is I’ve turned off the power washer. So basically, the water’s just
bypassing the engine, and now we have low pressure
coming through here. You definitely don’t want to do this
with the engine on. That would cause a catastrophe. – It would be a plant catastrophe. So the first tip we’re gonna be using
is our soap tip, ’cause we’re gonna start with our cleaner. All right, cleaner’s in, so, Jon,
why don’t you show us how we go about
starting our pressure washer. – First thing we want to do
is turn our fuel control on, then we’re gonna pull our choke out
and then put our ignition switch to on. And then we’ll give it one pull…
– Ah! Safety first. – Ah, you got me on that one.
– [chuckles] – We’ll give it one pull, and then you’re gonna wait
for it to start, like sound like it’s choking a little bit, and then you’re gonna
push the choke back in, and then you’re good to go. [engine revving]
– All right, cool. I’m gonna start off with soap. Okay, with this wand,
there’s a safety on here and you wanna make sure
that you engage the safety and then pull the trigger. When I’m applying my cleaner,
I’m gonna start from the bottom and work my way up to the top. Start no less than a foot away, because you kind of want to make sure
you have the right amount of pressure and see how your surface responds
at first. And you’re gonna work in just nice,
even back-and-forth strokes. Basically the same application, even though we’re starting with
our cleaner, as when we are actually power washing. This tip here is very low pressure,
and it’s to apply the cleaner. Now, the interesting thing is if I swap this to a pressure washing tip,
the soap will not come out. As you can tell,
I’m working from bottom up. If I work top down, we could potentially
have some streaking issues. Now, I’m gonna work on this whole section,
get the soap on. I don’t want to let the soap dry. And then I’m gonna switch
to a pressure washing attachment, to my 40-degree,
and then give it a good rinse. All right, I’ve reached about as much
as I can with the standard size wand, so Jon has the extension wand,
which actually extends to 18 feet and will allow us to get all the way
at the top without using a ladder which isn’t very safe. Now, in order to swap between the two,
we need to shut our water off again. I’m going to kind of drain this out, make sure there’s not
a lot of pressure here–okay– and then remove the soap tip from here, and we’ll put it onto the longer one. And then I’m gonna disconnect
my high-pressure hose. – And then we’re just gonna put
our quick connect right onto the end. – Great.
– We’re loaded. – And now we’ll turn the water back on. [engine revving] [mellow music] All right, we have fully soaked the top, and now we’re gonna switch this out
while we have our extension wand, and I’m putting on my 40-degree. Has the widest fan. It’s actually the most common
like multipurpose one. Our surface is still wet, so we want to
get this pressure washed right away. Now, for this, Jon’s gonna
start at the top and work his way down. That way,
any dirt that’s being knocked down isn’t falling on a clean surface. [mellow music] Now, with this I should mention
that we’ll start out further back, but depending on how our surface
is handling the pressure and how hard the dirt is to come off, we may end up in a little bit closer
for some hard-to-get areas. Okay, so the first side of the house
is done, and before we start to really tackle
the power washing on the front, we clearly have a bit of an issue
that we need to take care of here. What we’re dealing with is a rust stain
from an old irrigation system. We don’t feel like pressure washing alone
will take care of that, so if we don’t remove the rust, the new paint job
will not adhere to the brick, so we’ve got to take care of this
the right way. – So this is a RustAid,
and this is going to help eliminate any of the stains that have accumulated
over the years. – And we’re just going to apply that
using a pump sprayer. Okay, so to do this,
Jon is working from the bottom up. It makes sense to work all the way down
and across, starting from the bottom, so that way
the chemical isn’t dripping down, kind of rinsing itself off. Once this sets up for a little bit,
we’ll leave it, come back, check on it, and then we’ll rinse it off. And you always want to make sure
to read your specific label for safety precautions. This is a serious cleaner,
so you want to make sure that you’re following their steps exactly. All right, this has had
some time to set up, and now I’m gonna pressure wash it off. I am using the 40-degree tip.
It’ll do a really good job on this brick. With brick, you don’t want to go
too powerful. It could get in between
and corrode away the mortar. So 40 will be perfect for this. All right, now we applied the remover
from the bottom up. When I rinse it,
I’m gonna start from the top down so that the chemicals
are running down to the ground. Okay, so you can see that
even though this is brick, this is coming off really nicely, and none of the brick is chipping away,
so I can get a bit closer. One thing to note is that you can
change the orientation of your tip, so it can spray vertically
or more horizontally. Right now, it’s working out really well
for me to spray vertically and kind of work my way along the brick. [energetic music] As you can see,
this is really working very well. It’s taking all the rust off. And don’t worry if there’s some
little areas of paint chipping. This house is being prepped to paint,
so we’ll take care of that later. This rust stain
is gonna be gone in no time. Okay, another situation
that you might encounter is when vegetation–
and in this case, vines– kind of grows up against the house
that leaves marks here. So what I’m gonna do first is try and just kind of bang loose
anything I can with my hand. But then our process
is gonna be exactly the same as over on the other side of the house. We’ll use the detergent
and then power wash it off. [bright music] All right, so for this area here
around the door, I want to be really careful
never to pressure wash on any window seams where there’s caulking or right around the edges of my doors. So what I’m gonna do
is stay clear of that, but I’m also gonna take a little step back
so there won’t be quite as much pressure. [cheerful music] You want to be sure that you don’t
power wash any living creatures like my little lizard friend,
so I’m gonna get rid of him. Go on, friend. – We good?
– Yeah. We’re good, all clear of lizards! – All right. [upbeat music] – Took us a couple of hours, but this house is completely
pressure washed and looking so much better. If you plan to paint after
pressure washing your house, make sure you give it a couple days
to really fully dry before moving on to that next step. Whether you are preparing
to paint your home or just need to get it looking
nice and clean and new, I hope that you walk away from this video feeling completely confident
in knowing how to pressure wash and do it the right way. And remember, as always:

  1. Congrats on making something so simple, complicating. Just whip out the good old commonsense and find out how to start the damn thing.

  2. Wearing eye glasses when just turning it on it’s kind of over kill with the protection… I mean when you turn on your car, no one wears eye protection

  3. If I have to wait for it to cool down than I wouldn't want to go with a gas powered washer, I don't have the patience to wait! LOL Good video though, very informative!

  4. Would have been nice to show how to pressure wash other surfaces, like wood fencing,decking, vinyl siding….and also show how to use electric pressure washer, because when you use electric you have to do certain procedures so that water does not drip toward you extension cord connection ….ok video, but could have been a little more detailed for all types of washers

  5. MONICA!!!!! 😍 Wish I knew all this before I 1st used the pressure washer 😍 Specially about the clothes 🤣🤣🤣 Let me just say that washing muddy ciment it was a "beauty mask" adventure 🤣🤣🤣 When is your WEEKENDER coming back? 😍

  6. I worked for a cleaning company (like maids) my boss bought a pressure washer and wanted to try it out on a customers house…that entire home ended up looking like a kid drew curly scribbles alllll over it. I mean all of it. It didn’t get better when it dried.

  7. I use a pressure washer to clean my truck all the time. I use low pressure 1200psi and a 40° tip. It works perfect. Don't tell me what to do. 😂

  8. Keep Monica coming !! Can you do some more stuff related to rentals ? Would love some longer term temp upgrades.

  9. Why are they using someone who has this much talent for a pressure washing video? Come on Lowe’s… Utilize Monica‘s talent elsewhere and save this sort of video for a beefy contractor.

  10. Yes! I absolutely need this! I need to do this this summer and have never done it before. Thank you for creating this!

  11. You want to learn a better way to clean? Learn how to SoftWash, Downstream and or X/M-JETTING. No high pressure needed, no telescopic wandwands, no ladders. Apply your Chem, let dwell 5 to 7 minutes and then rinse off. That simple. Quik and easy. A much better process than "Pressure Washing", because it's actually soft washing.

  12. What's wrong with clean lizards? Please do more videos with your hair down and beautifully blown out. Love your color and length. Good technical tips. You forgot to warn about running the power washer without squeezing the handle. It will bypass the water and heat up the pump.

  13. Maybe I'm missing something, as I don't have or never used a "new" gas pressure washer. But shouldn't they made a point of purging the air out of the line, before starting the engine.

  14. sorry but your wrong. pressure washing your house will cause it to rot. your house is designed to shed water from above (rain) when you pressure wash you push water under lap siding and on aluminum siding water can actually lay in the J bend at the bottom of the siding. this holds true for vinyl siding too. the water can lay and cause mold issues. the best but not easy way is with a bucket soap and water and a brush on a pole and rinse with the garden hose. Ive been a painting contractor over 50 years and im speaking from experience. dont be-leave this twit

  15. You teach the wrong way you keep your lance 90°, if you do it the right way put the lance in an angle of 45°. Then you are cleaning the right way!

  16. Hi, your advice not to use a pressure washer to wash a car is bad advice. Electrical pressure washers with a fan nozzle and held more than about a metre from the car are just fine.

  17. You can wash a car with a pressure washer, just need to attach the right tip and keep the right amount of distance. All car detailers use pressures washing techniques and foam cannon's.

  18. There are so many things you said in this video that are incorrect
    The psi is not the most important thing for a pressure washer gpm is
    Pressure washer can be used to clean vehicles safely when using the proper tips you can regulate the pressure(not using the standard tips that come with the pressure washer)
    You should never use any kind of pressure to clean the house you should allow your chemicals do the work

  19. Most if the time you dont want to use high pressure on a house and every Auto detail shop uses pressure washers on cars. Never start the pressure washer without having trigger pulled

  20. Use pool chlorine in your soap additive tank when you're done wasting time with the box store house cleaners.

  21. You should have used a modern gas can to fill up the machine. That way the user can get a good idea of how much gas to expect to have all over the pressure washer and themselves.

  22. Why should you not refill while it’s hot? How long will it take to cool down if you do wait? There’s no live flame why can’t you refuel ?

  23. I almost turned this off when she said you shouldn't use a pressure washer on a car. That statement was incorrect. I've been using a pressure washer on my truck for over a year with not a spec of damage from it. A person should just know what nozzle tips to use and not to use.

  24. Fun to watch. These two are definitely weekend warriors. I hope they NEVER quit their day job. If these two showed up to clean my house, I'd fire them immediately. Who uses a HIGH PRESSURE to clean the side of a house. Soft washing with chemicals is the way to go. It's 2019 people. Not 1990

  25. Step 1 hold gun
    Step 2 pull trigger
    Step 3 let air exit system
    Step 4 start pressure washer
    Step 5 enjoy music while doing chores

  26. "Don't worry about the paint chipping, this house is being prepped to paint" …Yeah, but what if my house isn't being prepped to paint, should I still not worry??
