Spray Bedliner Height and Surface Area Whether an area 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 earth of sprayed truck bed liners can’t be overlooked. spray on bedliner The height dimension is its thickness that is a great deal 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 outside a paint booth to contain these toxins with protective respiration gear for the applicator. They are at the very 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 only $300.00 & can exceed $600.00 with respect to the size section of the box to be covered. Thickness must play a role in cost since oahu is the only direct correlation to the amount 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 are usually 1 part, applied with a simple 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 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 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 all about 85 sq ft with bed rails covered. An economy bed is all 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 should be understood that due to spray on product’s high expense maximum thickness shouldn’t be necessary overall parts of a truck bed. Main regions 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 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 near no stress zones like underneath the bed rails = 135/2)= 67.5 mils average thickness required 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 equals 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 no less than 2.6 gallons of product.
Only at that rate DIY spray on bed liner kits consisting of 1 gallon are insufficient for sure protection within 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 fair thickness. This price doesn’t take into account incidental supplies & the value of one’s time to line your bed. And also this assumes you’d involve 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 class spray lining product range from about $20 to $60 per gallon; the common 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 product range of $300.00 to $600.00 can be a fair price with an experienced or specially trained professional line your truck bed with the proper 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 bed lining liquids are not the same formula. And we already know that quality must also depend of thickness that is 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 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 in a non-professional, protected area in the building. Therefor DIY cannot match the caliber of professionally applied bed liners. For qualities due to specifications between brands or different products employed by professional bed liner shops, the professionals must have these specs documented & designed for comparison where DIY kits rarely or never mention or document any quality specs.
