Spray Bedliner Height and Surface Area Whether an area to be coated could 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 earth of sprayed truck bed liners cannot 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 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 quite high spec strength characteristics which can justify their higher cost than DIY. Cost range is only $300.00 & can exceed $600.00 with regards to the size part of the box to be covered. Thickness must may play a role in cost since it’s 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 an easy spray gun or basic roller & simple directions. Although surface preparation is very important most DIY bed liners don’t mention this as a necessity. spray on bedliner 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 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 a lot of 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 a long time of protection on a truck bed. For purposes of average calculation when 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 about 85 sq ft with bed rails covered. An economy bed is 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 ought to be understood that as a result of spray on product’s high expense maximum thickness shouldn’t be necessary over all elements 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 top of the walls, inner box & cab’s wall to be not as thick with full protection; that 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 near no stress zones like underneath the bed rails = 135/2)= 67.5 mils average thickness needed for longterm 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 equals 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 longterm 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 on the long hall. At a high 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 good thickness. This price doesn’t take into consideration incidental supplies & the value of one’s time for you to line your bed. This also assumes you’d have some skill to apply it thicker where needed with a regular or neat appearance. As for getting hired sprayed with a professional, OEM pricing of higher a grade spray lining product vary from about $20 to $60 per gallon; the average being $40/gallon.
You could now understand having 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 quite a reasonable price to have experienced or specially trained professional line your truck bed with the proper quantity 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 know that quality must also depend of thickness that will be the amount of product. The key reason why professionally applied spray lining products require specialized protection is because of 2 ingredients: VOC (Volatile Organic Compounds) & isocyanates. In general 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 in the building. Therefor DIY cannot match the grade of professionally applied bed liners. As for qualities as a result of specifications between brands or different products utilized by professional bed liner shops, the professionals needs to have these specs documented & designed for comparison where DIY kits rarely or never mention or document any quality specs.
