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 cannot be overlooked. The height dimension is its thickness which can be much more important than area in determining the spray lining job’s quality. Actual product qualities should 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 outside of a paint booth to contain these toxins with protective respiration gear for the applicator. They’re at least 2 parts, require correct preparation & many require highly specialized equipment to apply. spray on bedliner These formulas usually provide very good spec strength characteristics which might justify their higher cost than DIY. Cost range is as little as $300.00 & can exceed $600.00 with respect to 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. These are usually 1 part, applied with an easy 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 a full 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 simple 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 reality 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 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 because of 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 upper 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 a typical height of 67.5 mils… (125 mils = maximum with a finer coat on less stressed parts & 10 mils for close to no stress zones like underneath the bed rails = 135/2)= 67.5 mils average thickness necessary for long haul protection.
Using 62.5 sq ft average area & 67.5 mils average height we may 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 a typical truck bed at fair height for long haul protection requires at the least 2.6 gallons of product.
At this rate DIY spray on bed liner kits consisting of 1 gallon are insufficient for real protection on 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 simple spray gun plus tax for a reasonable thickness. This price doesn’t take into account incidental supplies & the worthiness of one’s time to line your bed. This assumes you’d possess some skill to use it thicker where needed with a constant or neat appearance. For setting it up sprayed with a professional, OEM pricing of higher a grade spray lining product range from about $20 to $60 per gallon; the average 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 product range of $300.00 to $600.00 can be quite a fair price with an experienced or specially trained professional line your truck bed with the proper quantity 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 different formula. And we already know that quality should also depend of thickness which can be the quantity of product. The reason 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 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 within a non-professional, protected area in a very building. Therefor DIY cannot match the quality of professionally applied bed liners. For qualities because of specifications between brands or different products utilized by professional bed liner shops, the professionals must have these specs documented & available for comparison where DIY kits rarely or never mention or document any quality specs.
