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, in the world of sprayed truck bed liners can not be overlooked. The height dimension is its thickness that is a lot 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 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 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 area of the box to be covered. Thickness must 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. They’re 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 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 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 several years of protection on a truck bed. For purposes of average calculation when we look at 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 typically 62.5 sq ft. We’ll use 62.5 for purposes of simplicity.
Before applying our coverage formula it ought to be understood that because of spray on product’s high expense maximum thickness shouldn’t be necessary over all areas 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; this 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 to no stress zones like beneath the bed rails = 135/2)= 67.5 mils average thickness needed for long haul 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 common 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 sure protection on the long hall. At a cost of $100.00 per gallon this translates to $260.00 (2.6 X $100.00) or $290.00 with a basic spray gun plus tax for a fair thickness. This price doesn’t take into account incidental supplies & the worth of one’s time and energy to line your bed. And also this assumes you’d have some skill to apply it thicker where needed with a consistent or neat appearance. For getting hired sprayed by way of a professional, OEM pricing of higher a level spray lining product vary from about $20 to $60 per gallon; the common being $40/gallon.
You may now understand with 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 could be a reasonable price to have experienced or specially trained professional line your truck bed with the right quantity of top quality product generally unavailable in DIY bed liner kits.
Factors of Spray Bedliner Quality
WHAT ABOUT QUALITY? It stands to reason that all bed lining liquids are different formula. And we know that quality should also depend of thickness that is the quantity of product. Exactly why professionally applied spray lining products require specialized protection is because 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 in the building. Therefor DIY cannot match the caliber of professionally applied bed liners. For qualities because of specifications between brands or different products utilized 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.
