Tips On How To Use Latex Paint In A HVLP Paint Gun

High Volume Low Pressure, or HVLP, paint guns are in style for applying paint indoors. The low pressure used to draw the paint out of the gun significantly reduces the amount of over-spray produced by traditional compressed air paint guns. This decrease pressure works well with oil-primarily based paints and finishes but presents some obstacles when utilizing thicker, heavier latex spuiten paint. These obstacles can be overcome with a bit of extra equipment and paint preparation.

Paint Preparation
Quality latex paint is significantly thicker than traditional finishes and have to be thinned before it is helpful as a twig finish. Insufficient thinning results in the paint coming out of the spray gun in ugly blobs or not at all. Thin the paint with water and blend well earlier than spraying. The amount of water required varies with the model and high quality of the paint. Begin by thinning the paint by adding 10 percent water and mixing thoroughly. If the paint remains to be too thick, add a small amount of water and blend again. Don't use more than 25 % water in any paint. Extreme thinning reduces the paint's ability to adright here to and cover a surface.

Additives
When thinning alone would not work, use a latex paint conditioner to decrease the viscosity. Latex paint conditioners are designed to improved the paint's ability to stream with out thinning the paint and impairing its ability to stay to and cover a surface.

Straining
Use a normal cone paint strainer when filling the paint gun cup. The opening on a standard HVLP nozzle is 1.four millimeters and might be clogged with very small bits of debris. Once the nozzle is plugged, you'll have to take the gun aside and clear the obstruction. This is a messy procedure that may be avoided through the use of a strainer. In the event you can't locate a paint strainer, pantyhose make a superb substitute.

Hose Length
The turbine blower on an HVLP paint gun produces heat that's fed directly to the paint when utilizing a short hose. Heating the paint reduces the drying time which affects its ability to move and degree out. Adding a six-foot section of air hose between the gun and the turbine reduces the working temperature of the air atomizing the paint and alleviates this problem.

Approach
Hold the gun no more than eight inches away from the surface you are painting. Start on the prime on vertical surfaces. For horizontal surfaces, begin alongside both edge and work your way toward the opposite edge. Totally wet the surface of a bit earlier than moving to the next.

Test and Follow
A number of factors are involved in getting the paint to the right viscosity. Temperature, humidity, turbine output and the physical characteristics of the paint all affect the paint's ability to circulate smoothly. Getting the right mix to your state of affairs is a matter of trial and error. The very best approach is to test spray the paint on a bit of cardboard or scrap every time you thin it. After you have a combination that flows smoothly, apply your spraying technique on the testing surface until you achieve a consistent finish. Wasting a small quantity of paint working towards is less expensive and time-consuming than removing a bad paint job and starting from scratch.
