Spray Bedliner Height and Surface Area Whether a floor to be coated may be the bed of a pickup truck or any 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 can’t be overlooked. The height dimension is its thickness that is far 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 a paint booth to contain these toxins with protective respiration gear for the applicator. They are at least 2 parts, require correct preparation & many require highly specialized equipment to apply. These formulas usually provide very good spec strength characteristics that might justify their higher cost than DIY. Cost range is as little as $300.00 & can exceed $600.00 depending on the size area of the box to be covered. Thickness must may play a role in cost since oahu is the only direct correlation to the amount 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 essential most DIY bed liners don’t mention this as a necessity. spray on bedliner These types of are urethanes sold as 1 gallon to cover a full size truck bed available through retail outlets. Average retail price is $100.00 plus tax with a little roller, exceeding $130.00 with a fundamental 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 when needed or true. In reality with any high spec professional application 1/8 inch (125 mils) usually provides many years of protection on a truck bed. For purposes of average calculation if we think about 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 full 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 should be understood that due to spray on product’s high expense maximum thickness shouldn’t be necessary overall parts of a truck bed. Main aspects of highest stress on a truck bed are the tailgate, rear half end of the bed, lower sidewalls & back of fender wells. This leaves the top of walls, inner box & cab’s wall to be much less thick with full protection; this really is about.5 of the area. We’ll use an average 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 beneath the bed rails = 135/2)= 67.5 mils average thickness required for long term protection.
Using 62.5 sq ft average area & 67.5 mils average height we can now apply the formula for accurate calculations: 1 gallon = 1,604 sq ft at 1 mil means 23.8 sq ft at 67.5 mils thick. Now if the average bed is 62.5 sq ft, just divide by 23.8 = 2.6 gallons. Therefor spray lining an average truck bed at fair height for long term protection requires no less than 2.6 gallons of product.
At this rate DIY spray on bed liner kits consisting of 1 gallon are insufficient for real protection over the long hall. At a price of $100.00 per gallon this means $260.00 (2.6 X $100.00) or $290.00 with a fundamental spray gun plus tax for a fair thickness. This price doesn’t take into account incidental supplies & the worthiness of your time for you to line your bed. This also assumes you’d have some skill to use it thicker where needed with a regular or neat appearance. As for getting it sprayed by a professional, OEM pricing of higher a class spray lining product vary from about $20 to $60 per gallon; the average being $40/gallon.
You could now understand with an average cost of goods at $104.00 (2.6 X $40) plus labor & business costs, why the range of $300.00 to $600.00 can be a fair price with an experienced or specially trained professional line your truck bed with the correct level of high quality product generally unavailable in DIY bed liner kits.
Factors of Spray Bedliner Quality
WHAT ABOUT QUALITY? It stands to reason that most bed lining liquids are not similar formula. And we already know just that quality must depend of thickness that is the amount of product. Exactly why professionally applied spray lining products require specialized protection is due to 2 ingredients: VOC (Volatile Organic Compounds) & isocyanates. Generally these substances create rapid drying, better adhesion and higher strength (specialized characteristics are referred to 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 in a non-professional, protected area in a very building. Therefor DIY cannot match the caliber of professionally applied bed liners. As for qualities due to specifications between brands or different products utilized by professional bed liner shops, the professionals must have these specs documented & readily available for comparison where DIY kits rarely or never mention or document any quality specs.
