Spray Bedliner Height and Surface Area Whether a floor to be coated is the bed of a pickup truck or any other substrate 2 dimensions must be considered: total area & height. Where area is mentioned mostly, that 2nd dimension, on earth of sprayed truck bed liners can not be overlooked. The height dimension is its thickness that will be a whole 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’re at the very least 2 parts, require correct preparation & many require highly specialized equipment to apply. These formulas usually provide very good spec strength characteristics which may justify their higher cost than DIY. Cost range is only $300.00 & can exceed $600.00 depending on the size area of the box to be covered. spray on bedliner Thickness must may play a role in cost since it’s the only direct correlation to how many 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 straightforward spray gun or basic roller & simple directions. Although surface preparation is essential most DIY bed liners don’t mention this as a necessity. Many of these are urethanes sold as 1 gallon to cover the 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 many spray-on bed liner companies state, “1/4 inch thick” (250 mils), this height is rarely if needed or true. In fact 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 the full size truck box is all about 85 sq ft with bed rails covered. An economy bed is all about 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 regions of highest stress on a truck bed would be the tailgate, rear half end of the bed, lower sidewalls & back of fender wells. This leaves the upper walls, inner box & cab’s wall to be not as thick with full protection; this is about.5 of the area. We’ll use an average height of 67.5 mils… (125 mils = maximum with a finer coat on less stressed parts & 10 mils for near no stress zones like beneath the bed rails = 135/2)= 67.5 mils average thickness necessary for longterm protection.
Using 62.5 sq ft average area & 67.5 mils average height we is now able to apply the formula for accurate calculations: 1 gallon = 1,604 sq ft at 1 mil translates to 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 longterm protection requires at the least 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 high price of $100.00 per gallon this translates to $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 worth of your time to line your bed. This assumes you’d have some skill to use it thicker where needed with a regular or neat appearance. For setting it up sprayed with a professional, OEM pricing of higher a level spray lining product range between about $20 to $60 per gallon; the average being $40/gallon.
You might now understand having an average cost of goods at $104.00 (2.6 X $40) plus labor & business costs, why the product range of $300.00 to $600.00 can be a fair price to have an experienced or specially trained professional line your truck bed with the right number of high grade product generally unavailable in DIY bed liner kits.
Factors of Spray Bedliner Quality
WHAT ABOUT QUALITY? It stands to reason that bed lining liquids are different formula. And we already know that quality must depend of thickness that will be the total amount of product. Exactly why professionally applied spray lining products require specialized protection is a result of 2 ingredients: VOC (Volatile Organic Compounds) & isocyanates. Generally speaking these substances create rapid drying, better adhesion and higher strength (specialized characteristics are called 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 caliber of professionally applied bed liners. For qualities as a result of specifications between brands or different products used by professional bed liner shops, the professionals should have these specs documented & available for comparison where DIY kits rarely or never mention or document any quality specs.
