The Ultimate Beginners Guide to Powder Coating - How to Powder Coat at Eastwood


everybody Randy here in the East will

garage and today we're going to explain

the basics of powder coating to help you

understand the process and show you how

it's done and give you some tips that

will help you get professional results

and remember if at any time you want to

visit for more info when

the tools we're using all you have to do

is click or tap the button in the top

corner of the video to begin powder

coating you'll need a powder coating gun

powder and air compressor which can be a

small pancake compressor and air

pressure regulator and air filter to

maintain dry air and electric oven

dedicated for powder coating and a part

you want to coat that's it

we're going to show you how we transform

this old ski-doo snowmobile engine head

cover from dull gray aluminum to a shiny

blue metallic that will look great for

years to come plus we're going to show

you some tips and tricks using other

parts as well we're even going to show

you how to give the engine head cover a

cool two-tone appearance now before we

show you how we revive this old part

let's explain the process and show you

what you need in the simplest terms the

steps of powder coating are attach the

cup of powder connect the compressed air

attach the ground clamp and spray when

the part is coated with powder cure in

an electric oven but don't worry we'll

go know much more detail in this video

typically powder coating is done over

conductive metal parts but many items

that can withstand the curing

temperature of 400 degrees Fahrenheit

can also be powder coated like glass

which is done using a process called hot

flocking which will demonstrate later

but for this video we're going to focus

on the most common use of powder coating

which is for metal parts powder coating

is a process that involves applying an

extremely durable plastic coating using

an electrical charge and compressed air

before baking it permanently with heat

typically in an oven but heat lamps can

also be used using the large 240 volt

home oven has many benefits when powder

coating not only can you fit large parts

like wheels and home ovens but they also

recover much quicker allowing the oven

to get back to curing temperature faster

and giving you the best results its

durability is what makes it so popular

for parts on the underside of a car that

are commonly hit with stones are sawed

it's also great for hood hinges or

suspension components like Springs and

items that move

and stretch because it's more flexible

than paint powder coating is much safer

for the environment than paint because

it contains no solvents that produce

hazardous emissions or VOCs which also

means cleanup is quick and easy and

leaves you with no hazardous solvents to

dispose of just sweep up your floor and

blow out the gun and everything is clean

which is also much easier than cleaning

a paint gun let's discuss the process an

emitter rod electrically charges the air

in front of the gun compressed air moves

the powder out of the gun where it

passes through this charged air and

picks up a high voltage electrical

charge as these charged particles travel

through the air they're drawn to the

metal parts which have been grounded by

being attached to the ground lead of the

powder coating gun the electrical

attraction is how the powder particles

are able to get great coverage and reach

inside parts and around edges

unlike paint which travels in a straight

line out of the gun this is also why you

need a good ground to attract the powder

for the best coverage so impossible

ground directly to the part you're

spraying another advantage of powder is

that if you make a mistake you can

simply blow the part off and start again

which is a huge advantage of our

mistakes that are made during the

painting process

now once the part is coated you'll place

it in the oven to cure during this

process the first thing you'll see is

the flow out or melting of the powder

particles you'll be able to see this

happen as the powder becomes a smooth

even surface if it's a gloss it will

start to shine at this point a good rule

of thumb is to allow the powder to flow

out and then continue to cure it in the

oven for an additional 20 minutes at 400

degrees Fahrenheit but remember to check

the instructions for the powder you're

using a great tip that's more accurate

is to use an IR thermometer to check the

temperature of the part rather than the

temperature of the air in the oven when

the part reaches 400 degrees then cure

it for 20 minutes also heavier cast

parts will absorb more heat and may take

more time to reach the full cure

temperature which is another reason it's

beneficial to use an IR thermometer and

remember an extra five to ten minutes of

curing shouldn't hurt the powder let's

discuss safety when spraying powder

you'll want to wear safety goggles and a

dust mask cure the powder in an electric

oven dedicated for powder coating don't

cook in the oven after you've used it

for powder coating

and never use a gas oven to cure the

powder when cleaning up never use a

vacuum cleaner which could emit a spark

and ignite the powder always sweep the

powder with a soft brush and dustpan

also never smoke near the powder when

filling the gun applying the powder or

when cleaning never touch the emitter

rod to defuse the possibility of an

electric shock touch the end of the

ground clamp to the emitter rod and

remember never handle or touch apart

while powder is being applied because

you could receive an electric shock to

begin powder coating make sure you

remove anything that could be damaged by

the 400 degree temperature that is

needed to cure the part like grommets

bushings bearing seals or other plastic

components the part should then be

prepped like you would for paint

removing all dirt dust grease and oils

with a product like Eastwood pre paint

prep and then wipe with a quality tack

rag you will also need to remove any old

coatings like paint

since many paints won't withstand the

curing temperature paints will also not

conduct a charge which means the powder

won't adhere properly a great way to

remove paint and prep the part for

powder is by blasting in a cabinet or

with a pressure blaster we put the head

cover in the eastwood blasts cabinet and

use glass beads to fully clean the part

we used our large cabinet but if you're

only doing small parts Eastwood offers

other sizes of cabinets including a

bench top version that's great for small

parts or even crafts

if cleaning apart by blasting it's a

good idea to place the part in the oven

and heat it until it reaches 100 degrees

this will remove a charge you may have

created while blasting that could affect

your coverage you can also use a

chemical stripper like eastwood down the

metal to remove these coatings which

we've done with other projects like when

we restored an old set of wheels and

covered them in East with gloss white

and cosmic clear if your powder coating

a cast part it's also a good idea to

place the parts in a 450 degree oven for

an hour to bake out the impurities and

the IR thermometer is helpful for

determining the temperature of the part

if it's preheated or being hot flocked

an IR thermometer will tell you the

exact temperature of the part you're

coating while the oven thermometer will

read the air temperature and there could

be a difference between the two

especially if it's a thick cast part and

here are a few more things to look for

many body fillers won't with stay in the

hearing temperature and fillers that

will withstand the temperatures are not

electrically conductive so they will not

accept the charge powder and we'll leave

you with bare spots

wherever there's body filler so make

sure all body filler is also removed you

should also avoid touching the parts

with your bare hands because you will

introduce oils to the part which will

also affect powder adhesion parts can be

hung to be powder coated or placed

directly on the rack hanging the parts

from the oven rack is a great method if

you need to coat all sides of the part

if using a larger home oven you can

support the oven rack with two sawhorses

this is easier than attempting to powder

coat the part and then hang it on a rack

that's already inside the oven here's a

tip when powder coating a part that has

threaded holes use bolts not only to

protect the threads but to also give you

an anchor point to hang the part when

hanging parts make sure you're using

wire that doesn't have an anti rust

coating that could prevent proper

grounding stainless wire is great for

hanging parts when applying powder if a

part is bumped or touched before it gets

to the oven you can blow the powder off

and start over this is one huge

advantage over paint where you would be

forced to use a chemical stripper to

remove the paint before respraying

if you need to mask areas be sure to use

a quality high temperature polyester or

fiberglass powder coating tape polyester

tape is much thinner than fiberglass

tape and provides a sharp or cleaner

edge but fiberglass tape is more

flexible and will conform to irregular

shapes better to protect this engine

head cover off a ski-doo snowmobile

we're using the high temp polyester

masking tape to get a nice edge around

the cover use the narrow tape on the lip

and then use the wide tape to cover the

entire bottom with a cover flipped over

use a razor to cut along the edge also

tape off any other surfaces you don't

want powder coated and trim with a razor

if you need to tape off a large area you

can use aluminum foil in conjunction

with high temp masking tape this way you

can protect your parts while using less

tape high heat silicone plugs can be

used to cover and fill any holes to

begin powder coating select the powder

you'll be using and pour it into the cup

for this project we're using Eastwood

metallic blue powder which will really

make it pop when using Eastwood dual

voltage system and for best results it's

recommended that for the cup not to be

filled more than half

whey powder is made of my new particles

so different colors cannot be mixed

together like paint to create a new

color here's a tip make sure you're

using virgin powder so you know it's

pure and doesn't contain dirt or

contaminants powder can be swept sifted

and reused but for the best results use

virgin powder like we offer at Eastwood

it's now time to connect the ground

clamp and begin spraying the powder hold

the gun about 8 to 16 inches from the

part and apply using gentle steady

sweeping motions while moving around the

entire part the gun we're using only

requires 5 to 10 psi at a mere 2 CFM

which is why you can use a small pancake

compressor apply powder until the part

is uniformly covered and you can't see

through it a dual voltage gun like this

one from Eastwood is great because you

can switch the voltage to get the best

coverage on large flat areas as well as

in tight corners where you can get poor

coverage due to the Faraday cage effect

meaning the powder will be repelled from

those areas unless you're using a gun

that allows you to adjust the voltage

Faraday cage effect happens most often

in areas where the angles are about 90

degrees or tighter to avoid this effect

first set the powder gun to the lower

voltage setting to limit the charge or

building up on the part make sure you

have the deflector on the gun and turn

up the air pressure to allow more powder

to flow out of the gun also spray these

areas first because by spraying them

first you haven't built up as much of a

charge which will repel the powder start

spraying the area with a gun parallel to

the part and the deflector will direct

the powder out of the side and onto the

part once you spray the tight areas you

can remove the deflector and switch the

gun back to the higher voltage setting

to spray the remaining larger areas once

the powder is applied place the part in

the oven and cure we suggest curing the

powder at 400 degrees Fahrenheit once

the powder flows out and appears to be

smooth continue to cure for an

additional 20 minutes remember always

check the instructions for the powder

you're using for proper curing

temperature and time when it's fully

cured remove it from the oven and you'll

have a highly durable part that looks

great for years to come as you can see

the Eastwood blue metallic really made

this old snowmobile headcover look

better than it was when it was new and

the best part is that it didn't take my

investment or time to get these results

if you want to add a cool effect you can

sand through the lettering to give it a

two-tone appearance start with 120 grit

and then move to 600 800 and finally

1200 grit to remove all the powder as

well as the scratches from the previous

grits of sandpaper with the powder from

the lettering removed the cover looks

even better and it only added a few

additional minutes of work as you can

see the blue metallic looks awesome

against the aluminum lettering giving it

a cool two-tone effect plus we now have

a highly durable coating that will look

great for years to come to clean the gun

simply blow it off with your blow nozzle

no harmful chemicals or solvents to

dispose of like when mixing and spraying

paint not only is powder coating easy to

apply it's also easy to clean up even

from a floor in fact all you need to do

is sweep up the overspray that's why

when you're buying powder you should

make sure you're buying virgin powder

many companies who sell powder sell

reclaim powder which is why it may cost

a little less but you may not be getting

the best powder and it may show up in

your finished job now that you've seen

how easy it is the powder coat let's go

over a few other options chrome powders

can mimic the appearance of chrome but

typically need to be clear coated for

highest durability there is a trade-off

for this added durability because you

will lose some of the chrome appearance

additives like metal flakes can also

provide a great appearance to your

powder coated items translucent powders

can provide a great look and drastically

change the appearance whether it's

sprayed over chrome or a white base

these were sprayed first with white

powder and then top coated with a

translucent as you can see there's a big

difference in appearance whether the

base is chrome or white you can even

powder cook glass using a process called

hot flocking which means the part is

preheated before applying the powder

this is done because the glass won't

conduct a charge so it also won't

attract the powder when the part is

removed from the oven the powder is

applied quickly before the part cools

and that's because it's sticking through

the part because it's hot not because

it's attracted due to the static

electricity you can actually see the

powder begin to flow out because the

glass is so hot hot flocking can also be

done on metal objects to help with the

coverage especially on a second coat the

ground clamp is still connected to the

metal but you're gaining the benefits of

both electrical attraction as well as

the powder sticking to the

due to the heat and remember powder

coating is not only great for car parts

but also motorcycle frames and

components as well as doorknobs lawn

ornaments fishing lures stainless mugs

and even crafts I hope this helped you

understand powder coating and how easy

it can be to make your parts look great
