1. ORANGE PEEL If the finish is rough and resembles orange peel then the material is too thick It will not atomize properly and the surface will be spotty To remedy this add more thinner or appropriate solvent For fast drying products such as lacquers you may also want to add a lacquer retarder This will slow the drying time allowing the material to flow out and level nicely Retarders are available for other coatings too such as Penetrol for oil based paints or Floetrol for latex house paints NOTE With the newer water based materials orange peel is usually a result of spraying on too thick a film Try spraying an extremely THIN FILM but still WET coat With most other coatings orange peel is caused by material being too thick or not enough atomizing power This is why we suggest leaving the air control valve fully open when experimenting with a new coating material otherwise it will cause confusion If the the air control valve is fully open or perhaps removed for Latex spraying then orange peel can only be one cause the material is too thick and must be thinned GRITTY FINISH If the material is too thin it is likely to run or be over atomized producing a rough gritty finish Try thinning the product less and spraying a wetter coat BLUSHING Blushing is the common term used when the finish looks cloudy and white sometimes also called blooming It is caused by mois ture and is especially a problem when operating high2. VISCOSITY Follow the viscosity guide chart You will eventually learn to thin the material by experience Traditionally lacquers were thinned 50 50 even for high pressure spraying but this much thinning is not necessary However coatings manufacturers are reformulating constantly so it is always advisable to check with them Thinning a product excessively causes more overspray as well as runs Stringent air quality controls in some geographic locations may prohibit reducing by more than 30 Please check with the local jurisdiction in this matter Remember when you buy a can of paint lacquer polyurethane varnish etc over the counter it will most likely be formulated for brushing That means it will be too viscous thick and will require thinning to spray successfully This is especially true if there is no mention of spraying on the instructions on the can Check with the manufacturer of the coating to obtain advice on thinning their product 8 VISCOSITY GUIDE To test the viscosity of the paint material fill the viscosity cup to the brim and time how long it takes for the liquid to empty out through the hole We recommend you experiment to find the ideal viscosity for your application and record the information for the next time The chart below is only an approximate guide denoting how many SECONDS it takes for the material to flow out of the viscosity cup Always check with the manufacturer of the coating for assistance in

5. For work such as cabinetry or trim our equipment can be used successfully with latex paint The latex will have to be thinned with WATER approxi mately 20 3096 depending on the brand of paint And to improve the finish even more you can use an additive that will slow down the drying process so that the paint levels out nicely One product available is FLOETROL from the FLOOD Company in Ohio In the USA Call 1 800 321 3444 for your nearest supplier In the U K 0845 0618899 The ideal Aircap size setup is the 4 for household trim louver doors etc The Latex paint should be finish quality and not a cheaper grade When spraying Latex please turn the fluid knob to limit the paint to a finer spray This will increase the ratio of air to paint and result in better atomization and a beautiful finish Factually speaking it doesn t increase the ratio of air to paint but does the opposite it allows the air atomizing power to work on less paint thereby improving the quality of atomization Also it is usually helpful to remove the air control valve so that more air passes through the spraygun Finally adjust the pattern to a maximum size of 8 9 20cm smaller is ok Although it is possible to use our equipment for house painting walls and many end users do we feel that an airless gun or power roller is better suited to that kind of job However if you decide to do this kind of work you will need at least the 5 Aircap set
