Category: Question and Answer

Like many polyureas, urethanes or hybrids chemical reaction and fusion occurs to produce the cured coating.? Our SLPV Plural Component Lining consists of liquids (parts A & B- Resin/Binder) and solids (PART C- polyurea / polymer micropowder). ?High grade polyurea hybrid are excellent for bed liner with highest adhesion. Texture control is within the process between liquid and solid components; expansion at full cure plus emulsified (not fully melted) solids. ?The SPLV Line carries the only polyurea with controllable texture (hardness), profile (flat / slight orange peel / course), any UV color and purest clear. Less and more expansion equate to harder and softer textures (or more to less adhesion) respectively.

These materials, once fully cured, yield average 55% increase in its original volume.?

Example using materials in a standard 6? bed liner kit:

• Bed liner is mixed from 1:1 to 3:1 as solids: liquid.? For standard adhesion and thickness, use 1.5:1 as liquids to powders.

• .75 gallons of liquids mixed with 1.5 part solids will = 1.875 gallons * 1.23 (expansion) = 2.32 gallons fully cured

Other calculations for total volume of finished bed liner kit

Base coat + top coat to achieve thicker bed with greater adhesion –? In this example, a base coat comprised of 1:1 as solids to liquid for higher adhesion rate.? In conjunction, a second layer applied at 2:1 is used to achieve a thick top layer where adhesion is not as much of a concern between same materials (bed liner attached to bare metal versus 2^nd layer of bed liner bonded to first layer of bed liner)

How expansion is calculated for 2 layer bed liner

• Liquids for layer 1 is .75 gallons/2 = .375 gallons
• Solids for layer 1 is .375 gallons of polymers
• Total for layer 1 = .75 * expansion rate of .18 = .885 gallons
• Liquids for layer 2 is .375 gallons
• Solids for layer 2 is .75 gallons
• Total for layer 2 = 1.125 * 1.25 (expansion) = 1.4 gallons
• Total Sprayable gallons = 2.29 gallons

Our Polyhybrid coatings work best when applied with an ambient temperature above 70 degrees Fahrenheit. If you are applying our materials in cold weather we recommend using heating fans or heat lamps to achieve the proper temperature range.

Heat lamps

If using heat lamps the best approach is to expose the spray area until the general surface is the right temperature. Once the product has been sprayed it is a good idea to move the lamps in an circular motion to keep the applied heat in an even pattern. If you don’t, you will see an inconsistent pattern as the product cures at a different rate directly under the light.

Floor or fan Heater

We suggest using this type of equipment over lights because you get better distribution of heat with this hardware.

This answer applies to our coating on ANY surface

Spray-Lining SLPV coatings will adhere well to practically any surface. However, you need primers for the following conditions:

• Plastic Fenders, Bumpers, etc
• Bare Metal

Bare Metal Preparation

Whether it’s a truck bed, trailer, container, or other object, if you have a corrosion-free bare metal surface you will need an AUTO OR MARINE-GRADE 1:1 EPOXY PRIMER. There are many available on the market. The key is that it is 1:1 Epoxy Primer.

Plastic Fenders, Bumpers, etc

If you have worked with coating plastic surface you know that without the proper prep, coatings DO NOT adhere for any significant period of time. We recommend using House of Kolor AP-01 adhesion promoter to prep a plastic surface for our coatings.

The key to using this product is to apply the coating shortly after use of the adhesion promoter. The adhesion promoter works by making the plastic surface tacky with a chemical reaction. While the surface is reacting it is most capable of accepting a bond with another material. So, it’s important to use our coating shortly after treating the surface with the appropriate adhesion promoter.

Spray Lining and Coatings Always Gives?you the Right Amount of Coating

Most DIY Products advertise a “1 gallon truck bed kit”. Over time this has caused many consumers to think that “One gallon equals one truck bed”. This is not correct.

We believe it is a disservice to the public to think this way. If you read our Q and A about Bed Liner Thickness you’ll understand that it takes at least 2 gallons to do a basic 6 ft bed, and at professional thickness it requires 4 gallons.

Spray-Lining DIY Kits start at 2.3 gallons of sprayable bed liner. Plus you get a real professional spray bed liner gun, not a cheap schutz gun. With this better gun you can control texture and thickness very well. This allows you to customize the look of your spray coating and apply a better consistent coat which helps with your level of comfort and the finished product.

Quality Coatings Provide Quality Bed Liner Results

In addition to these factors, most DIY Bed Liner kits are 1 part roll on system. Spray-Lining is a 2 part polyhybrid coating that is used by professionals in the industry. We are the only company besides Scorpion Coatings that offers a professional product to the DIY consumer.

Here’s the calculation for any truck bed liner which is sprayed on:

1 gallon of any liquid covers 1604 sq ft at 1 mil (1/1000″).

Therefore:

total sq ft / (1604/mil height) = Gallons required to cover a specific area at a specific mil height.

Average Mil Height : Generally, for low stress areas you can go half the thickness of professional grade coatings. Therefore, if you are doing 20 sq ft @ 125 mils and you want to do 10 sq ft @ 60 and 10 sq ft @ 125 mils, your average = 125+60/2 = 185/2 = 92.5 average mil height

This is important when calculating actual material requirements. For floors, you do NOT want to use less than 30 mils when applying a protective coating. The mil height is required to provide the “protection”…… Be careful when reading other vendors product information because they typically do not expose this information in order to provide a “better price”.

Following the recent trend of applying bed liner to the outside of your vehicle saves you money and shows of the ruggedness of your auto. Doing these applications yourself requires a little bit of experience for a few reasons:

• It’s the OUTSIDE of your vehicle!! You don’t want to screw up
• You want to apply the perfect texture for washable yet rough look
• You want great adhesion for long term functionality
• Colors require a little bit more skill than black or grey

General Rules for Proper Texture and Thickness on External Body Bed Liner

Our Bed Liner material is a polyhybrid formula which is a full range coating that is chemical resistant and has excellent adhesion properties with many materials. So, this can be used in other coating applications like decks, boats, etc. The material bonds extremely well with wood, concrete and most metals. Spray-Lining materials are varied based on the specific type of application because you don’t want bed liner on your boat because of heat, extra flex, slip-proofing properties, etc.

Adhering to Plywood or Concrete

If you coat a piece of ply wood with Spray-Lining Deck Coatings or Bed Liner, let it set and then cut the edge off with a saw you will be impressed by the results. The coating will impregnate itself on a molecular level about 10 mils into the wood (or more based on varying conditions and formula). If you beat that piece of wood with a hammer, you will see the added support provided by this chemical bond. A similar reaction will occur with concrete.

What is the right CFM and PSI for my DIY Bed Liner?

Different Products require different settings. Spray-Lining SLPVH-100, which is the basic spray bed liner, requires between 9 cfm @ 80 to 11 cfm @ 120 psi. You can spray it with lower pressure settings if thinned more. Lower quality products require less CFM @ PSI because they are inherently thinner which means less of “bed liner texture” and more of a paint-type finish.

We have the most versatile spray bed liner that allows you to achieve a broad range of textures and finishes for your project needs.

That depends on who you are talking about. Most DIY Bed Liners are applied at most 30 mils which is 1/32 of an inch. If you read reviews of Raptor, Al’s and others you will see consumers state that they bought multiple kits.
A professional sprayed bed liner is supposed to be 125 mils in thickness in high use areas and less on verticals. However, this is the game… Some applicators may try and get away with applying less because they make more money and most people would not know the difference.

Spray-Lining Products are produced to be applied at 60 or 125 mils throughout the entire project. We are the only company that offers a DIY system designed to compare with a professional sprayed bed liner like Line-X or Rhino Linings.

Yes. Any material will adhere and protect better if it is thicker. So, in a relative manner, thickness ALWAYS matters. Different materials may have comparable specs to each other at different thicknesses, but, it’s not so significant that you could say, ‘this material at 1/32″ is as strong and durable as that material at 1/2″‘. It just doesn’t work that way….

Now once you get into an area where two products are significantly different in behavior and comparable in strength at extreme thickness differences, you are simply talking about completely different materials. In these cases, thickness will not be the most important factor because the chemistry will be profoundly different between these materials and in many cases, probably not intended for the same purpose.

About thickness

Companies can use thickness (or lack of thickness) as an exploit for the consumer. We don’t mean directly either. Just by excluding the fact of the important of thickness, consumers are not allowed the opportunity to make the right decisions when buying DIY. That’s why we talk about mil height all over the Net. We want you to have the best experience long term with your coating. We believe that this third element (thickness) is critical to DIY success.

At Spray-Lining the long term results of your bed liner job, floor or marine application is far more important to us than selling you a DIY kit. Our products may seem more expensive than many, but that’s because we are not “painting” a story for you. We give you the information straight.
