If you, which one would you like to choose? Well, yes, it does depend on the condition of the object. If it is in terrible condition, do not hesitate, and just go to get a new one; but if not, why don’t you buy a spray paint to renew it by yourself?
So here comes the problem: spray painting techniques.
Actually, not everyone has mastered the right way to use the spray paint. Here are some simple but useful tips that helps you master it and makes your spray paint job look like an artwork immediately.
They are divided into three parts as follows. Just follow them and do it!
Part One: Pre-painting
Don’t ignore the preparation, which is an indispensable part for your spray paint job.
Tip #1. Location Choose
You’d better do it outdoors, or choose a well ventilated area such as a yard. If you are going to spray inside, it is necessary to open doors and windows to let fresh air come in.
Tip #2. Weather Check
In fact, the weather is also a main factor that may influence your paint job, so you should also pay attention to it. Generally speaking, it is ideal to spray paint when the temperature is between 60F~80F and relative humidity is below 85%. Avoid painting in too hot or too cold weather.
Tip #3. Surface Preparation
Do not forget to make a proper surface preparation that is crucial to a perfect paint job. Both the surface of the working area you choose and the object you are going to paint.
Before starting your work, please make sure the working area you choose is free of any unrelated items that may be painted accidentally when spraying.
Object to be painted
Poor surface preparation will lead to uneven paint coats.
Check the surface of object to see if there is dust or stain, and adopt proper methods to make it clean and smooth such as sandpaper etc. According to what kind of surface you are going to paint. The way to prepare surface differs in different material a little as you can see below:
△ Metal Material Surface
Step 1. Clean dust or other particles on the surface with a moist rag
Step 2. Use a wire brush to remove the rust from the surface
Step 3. Remove any loose paint by using sandpaper, scrapper or putty knife
Step 4. Prime the entire surface to prevent dust or dirt
△ Wood Material Surface
Step 1. Wash wood surface with a trisodium phosphate (TSP) to break down the previous paint coats for better painting
Step 2. Use wood filler to pitch the holes, scratches or gaps on it
Step 3. Sand the surface until it becomes smooth
Step 4. Use a primer before painting.
△ Plastic Material Surface
Step 1. Use dish soap to remove dust with a soft cloth
Step 2. Lightly sand the surface
Step 3. Wipe down the surface with alcohol to remove any oils
Step 4. Apply a coat of primer to make a better painting
Tip #4. Instruction Study
Many people have never read the instruction before they use spray paint and thought it doesn’t matter. What I want to say is that there is always a basic and detailed direction for use in it.
Apparently, you can find almost all answers in it to what you are confused with during painting. Hence, please find the instruction on the can and read it thoroughly before you begin. It will help you a lot, trust me.
Tip #5 Equipment Preparation
In order to keep your spray paint job going on more smoothly, you can choose to be equipped with some practical devices if necessary. For example:
You can easily find that there are many painting masks sold in most hardware stores. Just get a respirator to prevent from inhaling paint fumes if you are painting a large furniture.
If you are painting something big like a desk, you can put down a large drop cloth in the working area to avoid over-spray. That can save you much time to do cleaning after finishing painting.
Likewise, when working with smaller object, the cardboard is a pleasant choice for you to set up a independent space for spraying paint. Due to its small size, you can put it on a turntable so that you are able to rotate it to spray in all directions as you like without touching it.
Spray gun, also named paint sprayer, is indeed a good helper if you plan to do a large painting job. Since too much pressure will result in overspraying, the spray gun can reduce overs-pray efficiently with more air and less pressure in it, thus avoiding unnecessary waste. Meanwhile, you can also finish painting large surfaces with an even coat in a more easy way by using it.
Tip #6. Spray Paint Test& Shaking
Find a scrap surface that is the same as your object or an inconspicuous area of the object if it is big, then try to spray on it to get used to its spray pattern and how the paint is sprayed from the can.
It is a common sense that shake your spray paint before using it. However, how long should we shake and how to shake, which maybe is not familiar to everyone. Here let me tell you, it often takes 3 or 4 minutes to shake for mixing the paint completely and you’d better hold it upside down and shake it.
Part Two: While-painting
After so many preparations for better spray painting, now it is the show time for your painting techniques. Don’t worry, learning and following these tips below will help you use the spray paint like a pro.
Tip #7. Keep proper spray distance
The distance that you hold the can away from the object could influence your painting outcome a lot. It is likely to cause some drippings if you hold the can and spray too close to the surface, whereas keeping too far from the surface may also cause uneven paint coats.
Therefore, it is necessary to keep a appropriate distance from the surface when you are painting. And the proper distance is not settled, which varies in different situations.
Using spray gun
If you spray with the help of spray gun, the distance for better spray depends on what kind of spray gun you choose. There are four frequently-used sprayers sold in the market, and they are airless sprayer, air assisted airless sprayer, conventional spray gun and HVLP spray gun.
Due to its different air and liquid pressure, the distance changes slightly:
For using airless sprayers, you’d better keep 12-14 inches away from the object to be painted. Compared with it, air assisted airless sprayer adopts lower liquid pressure, so the distance to spray turns into 10-12 inches.
As for conventional spray gun, it is better to hold the gun closer a little, about 8-10 inches. When it comes to the HVLP spray gun, it needs a shorter distance for 6-8 inches due to its lower air pressure.
Without the help of spray gun
When not using a spray gun, please look through the directions for use on the can and find its recommended spray distance, which ensures high quality of your painting.
Maybe different brands of spray paint requires have different requirements, but the spray distance just varies a little.
Therefore, if you didn’t find it, you can hold the can about 10 to 12 inches away from the surface to spray, that is OK.
In addition, you should try to keep the same distance away from it during the whole process. In other words, to move spray gun in a straight line not in an arc that leads to uneven paint coats.
Tip #8. Choose a right gesture
Adjust your gesture according to the height of object. To keep parallel to it, you can choose to stand or half squat. That makes you finish your paint job at ease. For painting small object, it may be better to set it high by putting it on a desk or other platform.
Tip #9. Use entire arm to spray
Moreover, you’d better use your whole arm instead of just using the wrist to move the can to spray, by which you can paint horizontally across the surface to get a more pleasant outcome.
Tip #10. Begin and finish spraying away from the side of object
Don’t start to spray directly from the side. Be sure to begin a little early, it is better to start your spray off the side, and keep going on to end spraying away from the object. With painting in this way, it can guarantee the smoothness of your painting surface greatly.
Tip #11. Keep spraying in straight lines
For the sake of minimizing uneven painting, remember to paint in straight lines rather than spraying out of order as you like that may result in a mess. You can sweep the surface from right to left or from top to bottom. That will make your paint job looks much better.
Tip #12. Better thin layer than thick one
There are always some people who is anxious to finish their painting in a fast way. They often prefer to spray a thick coat so that they can end painting in only one time. However, it is actually a wrong and unprofessional way.
Applying several thin coats at least three is much better than just one thick coat that is hard to dry and easily causes even surface. If you want your paint job looks like an artwork, don’t rush and be patient to paint more than three coats.
Tip #13. Overlap your previous spray lines
Due to the limited scope of the spray, it needs to spray single lines again and again to cover the whole surface. While doing this, it is best to always overlap your previous spray line slightly, maybe about one-third of it. That can make the entire surface get well painted and uniform in color.
Tip #14. Let it dry before spraying again
When painting a large object or metal, it usually requires several paint coats to form a better coverage. It is not difficult to find the re-coat time in the instruction on the can. Wait and allow the first paint coat to become dry completely, then continue your second painting or more.
Part Three: Post-painting
It doesn’t come to the end when you finishing spray painting. There are also several things you need to do to ensure your professional painting job. So please attach great importance to it and keep following tips in mind!
Tip #15. Final Check
After finishing, the first thing you should do is to check the object you painted. See if there is any flaws like drips or spots caused by accident pause during the painting. If exists, you can take a dry cloth to remove it and spray this area again before it becomes dry.
Tip #16. Full Dry
As we all know, it may take different time for various spray paint brands to let the paint dry. Therefore, check your spray paint instruction and find the recommended time for better dry. Don’t move your object until it has completely dried. Wait for its full dry.
Besides, here I have to mention that the environment such as temperature and humidity will influence the dry time a lot. So the fist tip, location choose I mentioned before becomes more important. Because you cannot touch and move it to a well ventilated place before it gets dry.
Tip #17. Valve Clean
Last but not least, when you finish all the steps above, there is still one more thing for you to do, that is to clean your spray paint valve to ensure the smooth second use for you.
How to clean the valve? Put the spray paint can upside down and keep spraying for several seconds until you see the spray becomes clear. That can protect the tip from being clogged.
Actually, it doesn’t take much time for you to look through the whole article.
