This along with some 2.0mm gravity feed […] CONTROL PAINT FLOW: Fully adjustable pressure to give you ultimate control of paint flow for any project size; RAC IV Switch Tip allows you to reverse the tip when clogged to keep you spraying; SPRAY PAINT UNTHINNED: Stainless Steel Piston Pump allows you to spray paint unthinned at high pressure. However, it is important that you thin-out your paint to the correct consistency before you start spraying. It is the easy process to mix water in latex paint and make it thin so that you can color the surface as per your wish. Spraying has so many disadvantages (masking, overspray, wind problems, viscosity etc.) Specifications for the Viscosity Cup - Large. The material can also be diluted, since the viscosity is also crucial for the material's spraying properties. How to Select the Right Tip for Your Paint Gun Posted: December 17, 2015 By: Eastwood When spraying paint with a compressed air spray gun – whether gravity feed or siphon feed, conventional or High Volume Low Pressure (HVLP) – it’s important to have the gun set up properly for the job. Buying the machine is … 2. Oil paint over-spray will float farther and stay wet longer, so it's even more critical to properly mask and protect adjacent surfaces.

Thinning the BM Advance by 10% with tap water and mixing it thoroughly – this cut the viscosity from 400 down to 160 or so. The ES G100 and G200 gelcoat spray guns support a range of 0.8 – 7.1 mm tips. To get better results, we are currently adding reducing solvents to lower the paint’s viscosity for spraying, and we have tried airless spray equipment from several suppliers with mixed results. Arrange water, clean and empty gallon cans for thinning latex paint. Make sure spraying is what you want to do and budget accordingly. Check the viscosity of the paint. If you’re paint spraying side-to-side (left to right, right to left) select a vertical spray pattern. Many quality control measures are based on viscosity. The viscosity test is a general guide to get the paint below the maximum thickness the sprayer can atomize. Discounts not valid on Titan sprayers, PaintLine products, Xtend Climb ladders, or Apollo HVLP sprayers. Paint Life Newsletter. Even the temperature around you can affect paint viscosity for spraying. Using a 2mm needle 3. What you are painting is important to a certain extent, but more important is what you are painting … You'll need different spray tips because the viscosity is different to latex paint.

To get better results, we are currently adding reducing solvents to lower the paint’s viscosity for spraying, and we have tried airless spray equipment from several suppliers with mixed results. This is called paint viscosity. The right nozzle size is a further factor that influences the spray pattern. For more technical details about paint viscosity, including a paint viscosity temperature chart head to … The thickness (viscosity) of canned paint works well for brushing, but if you plan to spray it, you'll probably need to thin it. However, that viscosity is not measured under just any set of conditions or done with just any viscometer. When you thinned down emulsion paint before spraying though, you need to remember it will need around 3 to 4 coats to completely cover and produce the finish you are looking to achieve.

Most acrylic paints will allow you to thin them up to 8 ounces of water per gallon, but this is insufficient to increase their viscosity for spraying. and you still have to cut in. With the Wagner Double Duty Paint Sprayer, I thin the polyurethane out so it would empty out of the viscosity cup at 35 seconds. Paint - the only paint that is suitable for home-use is Cellulose.

If you want the perfect HVLP finish you need to thin your products properly and testing with a viscosity meter is a must. Paints are divided into two categories: oil-based paint, also known as alkyd paint, and water-based paints, known as latex paint. As you can see, you can use enamel paints when airbrushing.

The Bottom Paint Store distributes ES Manufacturing Gelcoat Spray Guns. Once the viscosity has reached the right level, you can then use it to spray your projects. We have problems getting a consistently even distribution of a high-viscosity paint in the spray pattern, resulting in striping on the sprayed parts. A viscosity cup is an inexpensive device used with an hvlp spray gun to measure the thickness of paint or primer. Putting the 50/50 mist coat through it was okay, but the speed controls were not as fine tuned for that consistency (for this you are meant to use one of the high viscosity nozzles). Spraying acrylic paint is a mindset . Using a Viscosity Cup This is even more important if you’re spraying plaster or any material with a high viscosity. Try spraying without Floetrol® first, and if you experience orange pe crawling or other drying problems add the Floetrol®. For greater accuracy and reliability purchase a viscosity cup.
