Measuring Your Truck
Before applying Raptor Liner, you need to know how much material to buy. Measuring your truck correctly helps you get the right amount of liner. This saves money and avoids waste.
Accurate measurements include all parts you want to cover. This guide will help you measure your truck step by step.
Calculating Surface Area
Calculate the surface area to find out how much liner you need. Measure the length and width of each section. Then multiply these numbers to get the area.
Add the area of all parts you want to cover. This gives the total surface area to coat with Raptor Liner.
- Measure length × width for flat sections
- Include walls and floor of the truck bed
- Add smaller parts like wheel wells separately
Considering Truck Bed Dimensions
Truck beds vary in size and shape. Measure the length from front to back. Measure the width across the bed.
Don’t forget the height of the bed walls. Multiply length, width, and height to estimate the liner needed for all surfaces.
- Length: measure inside the bed
- Width: measure at the widest point
- Height: measure the walls of the bed
Including Doors And Panels
Covering the truck’s doors and panels needs extra material. Measure these parts separately. Add their surface area to your total.
This ensures you buy enough Raptor Liner to cover the whole truck, not just the bed.
- Measure door height and width
- Include side panels and tailgate
- Add all these areas to your total surface area
Estimating Liner Quantity
Knowing how much Raptor liner you need helps avoid waste and extra cost. It depends on the size of your truck and the application style.
This guide breaks down the key points to estimate the right amount of liner for your whole truck.
Coverage Per Gallon
One gallon of Raptor liner usually covers about 20 to 25 square feet. This coverage can vary based on the surface and how thick you apply it.
| Surface Type | Coverage per Gallon (sq ft) |
|---|---|
| Flat smooth surface | 25 |
| Rough or textured surface | 20 |
| Truck bed with wheel wells | 22 |
Number Of Coats Needed
Most truck bed liners need two coats to ensure good protection and durability. Some users apply a third coat for extra thickness.
- First coat fills in small gaps and sticks to the surface.
- Second coat adds strength and uniform coverage.
- Optional third coat adds extra protection against damage.
Adjusting For Texture And Thickness
Texture and thickness affect how much liner you need. A rough surface uses more material than a smooth one.
- Thicker layers require more liner per square foot.
- Textured or ribbed areas need extra to cover all surfaces.
- Apply thinner coats if you want to save material but expect less durability.
Tools And Supplies
Applying Raptor Liner to a whole truck needs the right tools and supplies. These items help you get a smooth, strong coating.
Using proper tools makes the job easier and improves the final look. Safety gear and surface preparation materials are also important.
Essential Application Tools
You need special tools to apply Raptor Liner evenly. These tools help spread the liner and cover all truck surfaces well.
- Spray gun or roller for even coating
- Paint mixing sticks to blend the liner
- Measuring cups for accurate mixing
- Paint trays for rollers
- Masking tape and plastic sheets to protect areas
- Extension poles for high or hard-to-reach spots
Safety Gear Recommendations
Raptor Liner contains chemicals that can harm your skin and lungs. Wear safety gear to protect yourself during application.
- Respirator mask to avoid inhaling fumes
- Safety goggles to protect your eyes
- Gloves to keep your hands clean and safe
- Coveralls or old clothes to protect your skin
- Ventilation fans if working indoors
Surface Preparation Materials
Preparing the truck surface is key to Raptor Liner sticking well. Use the right materials to clean and roughen the surface.
- Sandpaper or sanding blocks for roughening
- Degreaser or soap to clean dirt and oils
- Clean rags or towels for wiping down
- Masking tape and plastic to cover areas you don’t want to paint
- Air compressor or blower to remove dust
Application Tips
Using Raptor Liner on your whole truck needs care and good technique. Proper application helps the liner last longer.
Follow these tips to get a smooth and strong coating that protects your truck well.
Preparing The Surface
Clean the truck bed and other parts fully before applying the liner. Remove dirt, rust, and oil.
Sanding the surface lightly helps the liner stick better. Use a degreaser for best results.
- Wash with soap and water
- Remove rust and old paint
- Sand with 80-120 grit paper
- Use a degreaser to clean oil

Applying Even Coats
Apply the Raptor Liner in thin, even coats. This avoids drips and rough patches.
Use a spray gun or roller for smooth coverage. Keep your tool moving steadily across the surface.
- Start with thin coats
- Cover all areas evenly
- Overlap each pass slightly
- Keep a steady speed
- Do not overload the liner
Drying And Curing Times
Let each coat dry before applying the next. Drying times depend on temperature and humidity.
Full curing usually takes several days. Avoid heavy use until the liner hardens fully.
- Dry time per coat: 1-2 hours

Common Mistakes To Avoid
Applying Raptor Liner to your whole truck is a big task. Many make simple mistakes that can affect the final look.
Avoiding these mistakes will ensure a smooth, even application. Your truck will look great and be well-protected.
Overestimating Coverage
Many people think one kit will cover their entire truck. This leads to running out of liner before the job is done.
Check the manufacturer’s guidelines for coverage per kit. Measure your truck’s surface area to know how much you need.
- Measure all parts of the truck
- Consider buying extra if in doubt
- Remember, two coats are often needed
Ignoring Surface Prep
Skipping surface preparation is a common mistake. Proper prep ensures the liner adheres well to the truck.
Cleaning and sanding the surface before applying the liner is crucial. It helps in removing dirt and roughening the surface for better adhesion.
- Clean all surfaces thoroughly
- Sand to create a rough texture
- Wipe away dust with a clean cloth
Applying Too Thick Or Thin
Applying the liner too thick or too thin can cause problems. Too thick can lead to cracking, while too thin won’t protect well.
Follow the instructions for the right thickness. Use a gauge if needed to check your application.
- Use even strokes for uniform thickness
- Apply two coats for best results
- Check thickness with a tool if unsure
Cost Considerations
Applying Raptor Liner to your whole truck is a great idea. It helps protect your vehicle from scratches and damage. But knowing the cost is important before starting.
The cost depends on several factors like quantity needed and application method. Let’s explore these factors in detail.

It’s important to consider these additional expenses. They ensure the liner is applied smoothly and evenly.
Diy Vs Professional Application
You can apply Raptor Liner yourself or hire a professional. Doing it yourself saves money, but it requires time and effort.
Professional application can cost between $500 and $1,000. It ensures a high-quality finish but increases your overall expenses.
- DIY cost: $450 to $700 (materials only)
