High Volume Low Pressure, or HVLP, paint guns are fashionable for applying 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 decrease pressure works well with oil-based paints and finishes however presents some obstacles when using thicker, heavier latex laten spuiten paint. These obstacles might be overcome with a bit of additional equipment and paint preparation.

Paint Preparation
Quality latex paint is significantly thicker than traditional finishes and should be thinned earlier than it's useful as a twig finish. Insufficient thinning leads to the paint coming out of the spray gun in ugly blobs or not at all. Thin the paint with water and mix well earlier than spraying. The amount of water required varies with the model and high quality of the paint. Start by thinning the paint by adding 10 % water and mixing thoroughly. If the paint is still too thick, add a small amount of water and mix again. Do not use more than 25 % water in any paint. Extreme thinning reduces the paint's ability to adhere to and cover a surface.

Additives
When thinning alone doesn't work, use a latex paint conditioner to lower the viscosity. Latex paint conditioners are designed to improved the paint's ability to circulate without thinning the paint and impairing its ability to stick to and cover a surface.

Straining
Use an ordinary cone paint strainer when filling the paint gun cup. The opening on a standard HVLP nozzle is 1.four millimeters and could be clogged with very small bits of debris. As soon as the nozzle is plugged, you will have to take the gun aside and clear the obstruction. This is a messy procedure that may be avoided by using a strainer. In case you can not locate a paint strainer, pantyhose make an excellent substitute.

Hose Size
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 stream 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're painting. Start at the high on vertical surfaces. For horizontal surfaces, start alongside either edge and work your way toward the opposite edge. Fully wet the surface of a piece earlier than moving to the next.

Test and Practice
A number of factors are concerned in getting the paint to the precise viscosity. Temperature, humidity, turbine output and the physical traits of the paint all affect the paint's ability to circulate smoothly. Getting the right mix in 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 each time you thin it. After getting a mixture that flows smoothly, practice your spraying approach on the testing surface until you achieve a consistent finish. Losing a small quantity of paint training is less costly and time-consuming than removing a bad paint job and ranging from scratch.
