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

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

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

Additives
When thinning alone does not work, use a latex paint conditioner to lower the viscosity. Latex paint conditioners are designed to improved the paint's ability to movement without thinning the paint and impairing its ability to stay to and cover a surface.

Straining
Use a typical cone paint strainer when filling the paint gun cup. The opening on a typical HVLP nozzle is 1.four millimeters and might be clogged with very small bits of debris. Once the nozzle is plugged, you will have to take the gun aside and clear the obstruction. This is a messy procedure that may be prevented through the use of a strainer. Should you cannot locate a paint strainer, pantyhose make a great substitute.

Hose Length
The turbine blower on an HVLP paint gun produces heat that is fed directly to the paint when using a short hose. Heating the paint reduces the drying time which impacts its ability to circulation 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 might be painting. Start at the top on vertical surfaces. For horizontal surfaces, begin alongside either edge and work your way toward the opposite edge. Totally wet the surface of a section earlier than moving to the next.

Test and Follow
A number of factors are concerned in getting the paint to the best 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 for your scenario is a matter of trial and error. The best approach is to test spray the paint on a bit of cardboard or scrap every time you thin it. After getting a mix that flows smoothly, apply your spraying method on the testing surface until you achieve a consistent finish. Losing a small amount of paint working towards is less costly and time-consuming than removing a bad paint job and ranging from scratch.
