Spray Bedliner Height and Surface Area Whether an area to be coated is the bed of a pickup truck or some other substrate 2 dimensions must certanly be considered: total area & height. Where area is mentioned mostly, that 2nd dimension, on the planet of sprayed truck bed liners cannot be overlooked. The height dimension is its thickness that is a lot more important than area in determining the spray lining job’s quality. Actual product qualities must matter & is discussed later.
Spray Bedliner Professional versus DIY Kits Professional Spray Lining Higher grade spray on lining jobs applied by professionals contain enough hazardous ingredients to limit or prevent their use outside of a paint booth to contain these toxins with protective respiration gear for the applicator. They are at the very least 2 parts, require correct preparation & many require highly specialized equipment to apply. These formulas usually provide very high spec strength characteristics that might justify their higher cost than DIY. Cost range is as little as $300.00 & can exceed $600.00 with respect to the size area of the box to be covered. Thickness must play a role in cost since oahu is the only direct correlation to the number of gallons of costly product being applied & sold retail.
DIY Kit Spray Bed Lining DIY bed liner formulas are less dangerous for use by the consumer. These are usually 1 part, applied with a simple spray gun or basic roller & simple directions. Although surface preparation is very important most DIY bed liners don’t mention this as a necessity. Most of these are urethanes sold as 1 gallon to cover a complete size truck bed available through retail outlets. Average retail price is $100.00 plus tax with only a little roller, exceeding $130.00 with a basic spray gun included.
Spray Bedliner Coverage Formula This Coverage Formula sheds light on grey areas or mysteries with lining a truck bed (or any surface requiring superior protection): 1 gallon of any liquid equals 1,604 square feet at the height of 1/1,000 of an inch (1 mil). This assumes no loss to overspray or evaporation.
Although some spray-on bed liner companies state, “1/4 inch thick” (250 mils), this height is rarely if ever needed or true. Actually with any high spec professional application 1/8 inch (125 mils) usually provides a long time of protection on a truck bed. For purposes of average calculation when we look at a full size bed to be 8 feet long, 6.5 feet wide & 2 feet high, then outside dimensions equal 110 sq ft. It’s commonly known inside dimensions of a complete size truck box is approximately 85 sq ft with bed rails covered. An economy bed is approximately 50 sq ft which leaves an average of 62.5 sq ft. We’ll use 62.5 for purposes of simplicity.
Before applying our coverage formula it must be understood that due to spray on product’s high expense maximum thickness shouldn’t be necessary over all parts of a truck bed. Main aspects of highest stress on a truck bed would be the tailgate, rear half end of the bed, spray on bedliner lower sidewalls & back of fender wells. This leaves the upper walls, inner box & cab’s wall to be much less thick with full protection; this is about.5 of the area. We’ll use a typical height of 67.5 mils… (125 mils = maximum with a leaner coat on less stressed parts & 10 mils for close to no stress zones like under the bed rails = 135/2)= 67.5 mils average thickness needed for long term protection.
Using 62.5 sq ft average area & 67.5 mils average height we are now able to apply the formula for accurate calculations: 1 gallon = 1,604 sq ft at 1 mil equals 23.8 sq ft at 67.5 mils thick. Now if the typical bed is 62.5 sq ft, just divide by 23.8 = 2.6 gallons. Therefor spray lining a typical truck bed at fair height for long term protection requires no less than 2.6 gallons of product.
As of this rate DIY spray on bed liner kits consisting of 1 gallon are insufficient for sure protection over the long hall. At a price of $100.00 per gallon this equals $260.00 (2.6 X $100.00) or $290.00 with a basic spray gun plus tax for a reasonable thickness. This price doesn’t take into consideration incidental supplies & the value of one’s time and energy to line your bed. And also this assumes you’d have some skill to utilize it thicker where needed with a steady or neat appearance. For getting hired sprayed by way of a professional, OEM pricing of higher a class spray lining product range from about $20 to $60 per gallon; the typical being $40/gallon.
You may now understand by having an average cost of goods at $104.00 (2.6 X $40) plus labor & business costs, why the number of $300.00 to $600.00 could be a reasonable price to have an experienced or specially trained professional line your truck bed with the proper number of high quality product generally unavailable in DIY bed liner kits.
Factors of Spray Bedliner Quality
WHAT ABOUT QUALITY? It stands to reason that all bed lining liquids are not similar formula. And we already know that quality must depend of thickness that is the quantity of product. Exactly why professionally applied spray lining products require specialized protection is because of 2 ingredients: VOC (Volatile Organic Compounds) & isocyanates. Generally these substances create rapid drying, better adhesion and higher strength (specialized characteristics are known as tensile or tear psi, compression strength, elongation, elasticity & shore hardness). Unfortunately these being toxic & carcinogenic they’re not safe & usually not legal to use within a non-professional, protected area inside a building. Therefor DIY cannot match the grade of professionally applied bed liners. For qualities as a result of specifications between brands or different products utilized by professional bed liner shops, the professionals should have these specs documented & readily available for comparison where DIY kits rarely or never mention or document any quality specs.
