Spray Bedliner Height and Surface Area Whether a floor 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 can’t be overlooked. The height dimension is its thickness which is far more important than area in determining the spray lining job’s quality. Actual product qualities must also 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 beyond a paint booth to contain these toxins with protective respiration gear for the applicator. They’re at the 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 low as $300.00 & can exceed $600.00 depending on the size section of the box to be covered. Thickness must may play a role in cost since oahu is 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. They are usually 1 part, applied with a simple spray gun or basic roller & simple directions. Although surface preparation is important 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. spray on bedliner 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 many spray-on bed liner companies state, “1/4 inch thick” (250 mils), this height is rarely if ever 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 consider 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 approximately 85 sq ft with bed rails covered. An economy bed is approximately 50 sq ft which leaves on average 62.5 sq ft. We’ll use 62.5 for purposes of simplicity.
Before applying our coverage formula it ought to be understood that due to spray on product’s high expense maximum thickness shouldn’t be necessary over-all elements of a truck bed. Main areas 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 top of walls, inner box & cab’s wall to be not as thick with full protection; that is about.5 of the area. We’ll use the average height of 67.5 mils… (125 mils = maximum with a thinner coat on less stressed parts & 10 mils for near to no stress zones like underneath the bed rails = 135/2)= 67.5 mils average thickness required 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 means 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 the 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 real protection on the long hall. At a high price of $100.00 per gallon this means $260.00 (2.6 X $100.00) or $290.00 with a basic spray gun plus tax for a good thickness. This price doesn’t take into consideration incidental supplies & the worth of your time for you to line your bed. This also assumes you’d involve some skill to use it thicker where needed with a constant or neat appearance. For getting it sprayed by a professional, OEM pricing of higher a grade spray lining product range from about $20 to $60 per gallon; the typical being $40/gallon.
You could 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 can be quite a fair price to have experienced or specially trained professional line your truck bed with the correct 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 most bed lining liquids are not similar formula. And we know that quality must also depend of thickness which is 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 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 used in a non-professional, protected area inside a building. Therefor DIY cannot match the grade of professionally applied bed liners. For qualities because of specifications between brands or different products used 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.
