How A Spray In Bedliners Is Done – Step By Step

A bed liner will definitely transform the durability and look of the bed of your truck. Installing some bed liners is an easy thing but when it comes to doing the spray in bed liner in the right way, it might not be as simple as you might expect it to be.

Spray in bed liners are great due to the fact that, they can make your old truck to look great and your new one to look even better. You might think that the process is simple but the truth is that, it is more than you might think. Below are the steps of doing it

1. Pull The Truck In

The first step is taken by a technician or in this case because it is DIY, you who will spray the truck by taking it to the booth which is specifically designed for doing that job. The booth is one with ventilation which is upgraded, with a pumping system which is advanced to allow Resin and ISO to be sprayed via the spray gun nozzle at exact pressures and temperatures.

2. Remove Parts

The tailgate is then removed from the truck and set on a stand which is designed for spraying the bed of your truck. All other removable tie downs are removed from the bed of the truck to ensure that, they are not sprayed on in the process. You will have to reinstall them after you are done with spraying the bed so that they maintain a look which is clean.

3. Masking

You will have to mask the entire truck. It is good that you start with the line take as it is capable of providing a clear line where the bed liner’s edges are. A couple of layers of tape masking is done which is then accompanied by a full plastic layer which is able to cover the whole truck. The use of the plastic is to prevent overspray on the truck.

4. Sanding And Cleaning

Using a sander, you will have to sand the entire surfaces of the truck bed which will later receive the polyurea thermoplastic elastomer. When you sand, it will create a surface which is rough so that, when you do the spraying it will be able to stick to the bed of the truck in all the parts. 

You will then spray out of the truck bed with air and then wipe down all the surfaces with alcohol which is denatured. This alcohol will be able to eliminate anything which might interfere with the bed liner’s adhesion.

5. Spraying

It is now time to put on your suit together with the breathing mask, turn on the pump and hose heaters. The Resin and ISO are heated by the hose heaters to a temperature which is precise to enable them to spray out of the gun in a liquid from the way paint would.

When all the pressures and temperatures are okay, you will have to perform some practice spraying on a piece of plastic to ensure that if there are any adjustments you want to make on the gun, you do so before starting to spray the bed of your truck.

The gun works in such a way that, the resin, which is the black substance and the ISO  which is the adhesive substance, are in separate hoses direct from the gun. When they reach into the gun, they tend to mix with the air to create a mix which is perfect for the bed of your truck.

After the spray gun is working correctly, you will then spray it in the exact series that you want to. When you are doing the first coat, the tech is normally close to the truck surface with the gun about 2-3 feet away. When you are close, it allows a smooth, thick layer to be formed. 

Once you are done with a thick layer all over the bed of your truck, you will have to go back and ensure that, there are no areas left out of protection. The next thing to do is to stand about 5feet to 6 feet away from the truck surface and do a spray with a certain technique.

When you stand away, it will allow the bed liner to be able to dry a bit in the air before reaching the surface, to give the surface a certain texture when it sticks on it.  You will have to do this until all the truck bed has a texture which is according to your standards.

6. Removing The Tape And Plastic

You will have to pull all the tapes after 5 minutes of spray so that, you create an edge which will be clean for your truck. At this particular point, all the other plastics and tape are also removed.

7. Re-installing

You will have to add the tie downs to the truck back with the tailgate.

After all the above steps are done, you are done with the DIY spray in on your bed liner and it will be dry to the touch. But it will be best if you would leave the tailgate down for a day or two and not use it for some time so that, it is able to cure to the truck bed well.

Spray In Vs Drop-In Bedliner – Pros and Cons

Spray in or spray on bed liners are a painted coating, applied in a paint shop or garage using a spray gun. The type of coating which is painted on your vehicle will vary from one manufacturer to the next and from one product line to the next and that is why it is important to ask certain questions before you decide to purchase a drop in or spray in bed liner. You will want to know:

  • Get to know if the lienr is aliphatic or aromatic coating?
  • What is your particular vehicle’s process of preparation?
  • Is it possible to see your paint shop before I do the purchase?

Why would you want to ask the above questions?

Aliphatic Or Aromatic

Most of the spray on consists of polyurethane and this makes them, when the paint comes into contact with the atmosphere, that is when it hardens. But you will find paints that  are aromatic while others are aliphatic. The aliphatic compounds tend to maintain their pigmentation better than their aromatic counterparts. This means that the aliphatic don’t easily fade and thus, more expensive.

I would advise that, if you are not going for an aliphatic painting, then it means that, you will get an aromatic compound which will be cheap when buying, but expensive to maintain as it will fade very fast.

Process Of Preparing Your Vehicle

Since the spray on liners is all about paint, the preparation of the vehicle body surface is very important. If you do a rushed or poor preparation process, then the results might not be good as compared to a preparation which is quality.

Good preparation will include:

  • Ensuring that you strip your vehicle to the bare metal or primer using a sander or grinder.
  • Clean the surface which is newly sanded or grounded
  • You can use a chemical cleaner in addition to sanding and grinding process
  • Mask the grounded area carefully to avoid overspraying the back of your truck

Spray In Bed Liner


  • When applied correctly, it looks great
  • You are free to spray the coating in whichever place you want as long as you have prepared it.
  • The texture of the surface will keep the cargo from sliding.


  • The factory paint is destroyed meaning your truck’s corrosion warranty is invalidated  on the spray in coating parts
  • When doing the spray in, it has to be done in a professional manner, extraordinarily careful and attentive to details otherwise, the results might be destructive.
  • The warranties of spray in liners are not that good
  • There are no protections for dings and dents from cargo unloading and loading.
  • Depending on the features and the type of liner installed, it might be expensive.

Drop In Bed Liner

Drop in bed liners are simple and all you need to do is ensure that you get a specific one for your particular truck.  Most of the ones on the market are deemed to be universal meaning that, they don’t fit the right way and that is why most truck owners prefer the spray in to drop in bed liners.  If the drop in which is universal becomes loose, they are likely to wobble as you drive around and affect the bed of your truck painting.


  • It is inexpensive
  • You will DIY installation
  • The transferable/removable from one truck to the next
  • Your bed will be protected from dings and dents by the plastic liner when you are offloading and loading cargo


  • Due to the cheap price, most of them have poor fitment between the bed and the liner which can crack with time as they are weak
  • Their surfaces are slick meaning, there is a possibility of your cargo sliding and getting damaged
  • With a poor fitment, it can buffet in the wind as you are on the move
  • Things To Consider When Buying Spray-In Truck Bed Liner Kit

    If you are finding it hard to pick the best spray in truck bed liner kit, then this particular section will help you to identify some of the factors which are important that you will need to consider.

    1. Reviews

    One of the main factor to consider before you purchase spray-in truck bed liner kit are reviews about the same which are shared by others online. You can utilize their feedback to differentiate the possibilities. When you do so, it will be easier for you to determine how one product is better as compared to the next from a different manufacturer. You should pay attention to what is being talked about in regard to the bed liner spray in quality so that, you know what you are going to expect.

    2. Ease Of Use

    The good thing about the several sprays in on bed liners which are available in the market is that you can apply them on your own without having to call a technician to do the job for you. So long as you know the steps to follow, you can easily do it. This means that, when purchasing, you should check out how user-friendly it is and it has to come with all the necessary tools.

    The manufacturer needs to provide instructions which are detailed on how you are going to use it which will make it possible to achieve the right results.

    3. Color Compatibility

    Before you decide which spray on bed liner you are going to use, you have to consider your truck’s color. Ensure that you pick a color which will match perfectly well. You should also remember that the color change depending on how you apply it. If you overapply, then the color will tend to be darker than its actual shade.

    4. Durability

    When you are purchasing a spray on bed liner, ensure that, they will be able to stay on your truck surface for a longer period of time. It should take sometime before it fades off. Even when you expose it to the sun’s heat and other harsh elements, it should stand the test of time without having to peel or crack. If not, then it will be a waste of time and money. It has to also resist dust and stain.

    5. Quantity

    You have to determine how much you are going to use in order to complete the entire job. This will be pegged on the size of your truck.  You need to avoid buying more than what you will use to avoid wasting money.

    6. Inclusions

    You have to consider what the product you are purchasing include in the kit. There are some which are just sold as a spray in bed liners only while others include everything that you will require for the job which includes but is not limited to the applicator and gritting paper. I think the one with inclusions are better than without as you will not have to do another purchase before you do the job.


    It is not an easy task to select the best DIY spray in on bed liner kit. And even after you make your choice, you will have to select your method of painting, surface preparation, protection material buying, and other things. But despite all the aforesaid, it will be best that you do it yourself instead of someone else doing it for you:

    When you want to improve the appearance of your truck to add resale value or for your own pleasure, then the spray on bed liner kit could be the way to go. A truck with a bed liner that is defect free shows that you are taking good care of it and you have maintained it well. There are several reasons which can cause damage to the bed liner from wheel hitch installation to heavy loads installation, to UV damage and other factors. Custom black coat urethane spray on truck bed liner kit is my pick due the great advantages it has over the rest.
