The Way To Use Latex Paint In A HVLP Paint Gun

High Quantity Low Pressure, or HVLP, paint weapons are standard 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 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
High quality latex paint is significantly thicker than traditional finishes and have to be thinned earlier than it's useful as a sprig finish. Inadequate thinning ends in the paint coming out of the spray gun in unsightly blobs or not at all. Thin the paint with water and blend well earlier than spraying. The quantity 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 blend again. Do not 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 move with out thinning the paint and impairing its ability to stay to and cover a surface.

Straining
Use a regular cone paint strainer when filling the paint gun cup. The opening on a standard HVLP nozzle is 1.4 millimeters and may be clogged with very small bits of debris. As soon as the nozzle is plugged, you will have to take the gun apart and clear the obstruction. This is a messy procedure that may be prevented by utilizing a strainer. In the event you cannot find a paint strainer, pantyhose make a good substitute.

Hose Length
The turbine blower on an HVLP paint gun produces heat that is fed directly to the paint when using a brief hose. Heating the paint reduces the drying time which impacts its ability to circulation and stage 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. Begin on the high on vertical surfaces. For horizontal surfaces, begin along both edge and work your way toward the opposite edge. Absolutely wet the surface of a section earlier than moving to the next.

Test and Apply
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 stream 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 piece of cardboard or scrap every time you thin it. After getting a mixture that flows smoothly, follow your spraying approach on the testing surface until you achieve a consistent finish. Wasting a small quantity of paint practising is less expensive and time-consuming than removing a bad paint job and starting from scratch.
