Choosing The Right Sprayer When deciding on the purchase of equipment, take several things into consideration: What types of coatings do you typically apply? What tip sizes do your coatings require? How many gallons do you spray per week? What types of jobs do you usually do: residential (new or re-work), commercial, maintenance, industrial coatings? What is the available power (gas, electric, air-operated)? What is the size of your crew (relative to how many different people will use the sprayer)? How many guns do you want to use with the sprayer? What is the typical length of hose used at the job site? Who cleans and maintains the pump? As a general rule of thumb, after evaluating these items and your business, it is best to purchase one level above current needs. This allows your business to grow through the bidding and taking of either larger or more complex jobs with better investments in equipment. (Courtesy SprayTECH) |

Spray Tips (reprint #1) How to recognize that little thief on your job site |
||||||||||
Spray tips can be stealing from you. This may seem obvious, but many painters dont realize that running a tip to long is costing them far more than the replacement cost of the tip. The problem is how do you know if your tip is ready to be replaced. When we are asked in the store how long a tip should last we really dont know how to answer that question. Why is the answer so difficult? Because there are many factors that contribute to tip wear. Things like what pressure is being used to spray and what type of material are you spraying. For example a cheap latex paint (they tend to be more abrasive because of the coarse fillers that are used) sprayed at the maximum pressure a sprayer is capable of could last as little as 25 to 30 gallons. The same product sprayed at a reduced pressure may provide 50 or 60 gallons of tip life. A better product that is less abrasive sprayed at the optimum pressure setting may provide you with 100 to 125 gallons of tip life. All of this plus some brands and sizes of tip just last longer than others. So how do you know when it is time to replace that tip. The best indication that a tip is shot is the shape of the pattern. As an airless spray tip wears the pattern tends to go round. For example a new 517 tip will provide a spray pattern approximately 10 inches wide by about 2 inches across. As the tip wears the pattern becomes more oval, the 10 inch dimension becomes more like 6 inches and the 2 inch dimension becomes more like 4 or 5 inches and the 17 (the .017 orifice) becomes closer to 20 or 21. This is a real problem if your pump can only support a .021 tip. So why does this cost you money? because you are putting more paint on a smaller area with each pass. You need to make more passes to cover the same area taking more time while putting more paint on than necessary. And you run the risk of Tiger Striping the wall. Even if you back roll you cant always prevent the spray pattern from ghosting back through the dry finish. This costs you time, Paint and reputation. Hirshfields Spray Tip: Before you start spraying for the day test your spray pattern. If its not at least 3 times longer than it is wide, replace the tip. Otherwise that little thief will spend the day stealing from you. |
