Spray Bedliner Height and Surface Area Whether an area to be coated may be the bed of a pickup truck or any other substrate 2 dimensions should 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 far 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 the least 2 parts, require correct preparation & many require highly specialized equipment to apply. These formulas usually provide very high spec strength characteristics which can justify their higher cost than DIY. spray on bedliner The cost range is as low as $300.00 & can exceed $600.00 with respect to the size part of the box to be covered. Thickness must may play a role in cost since oahu is 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. 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. Most 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 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 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 when 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 typically 62.5 sq ft. We’ll use 62.5 for purposes of simplicity.
Before applying our coverage formula it must be understood that due to spray on product’s high expense maximum thickness shouldn’t be necessary total areas of a truck bed. Main regions 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 top of walls, inner box & cab’s wall to be much less 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 thinner coat on less stressed parts & 10 mils for close to no stress zones like under 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 can 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 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 high price of $100.00 per gallon this equals $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 consideration incidental supplies & the worthiness of your time for you to line your bed. This also assumes you’d involve some skill to apply it thicker where needed with a steady or neat appearance. In terms of getting it sprayed by way of 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 may now understand by 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 a reasonable price to have experienced or specially trained professional line your truck bed with the correct number 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 not the same formula. And we already know just that quality should also depend of thickness that will be the amount of product. The key reason why professionally applied spray lining products require specialized protection is a result of 2 ingredients: VOC (Volatile Organic Compounds) & isocyanates. In general these substances create rapid drying, better adhesion and higher strength (specialized characteristics are known 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 a very building. Therefor DIY cannot match the quality of professionally applied bed liners. In terms of qualities as a result of specifications between brands or different products employed 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.
