HVLP - Adjusting for a round pattern.

An hvlp spray gun can be difficult to use at first. Spraying whatsoever articulate finish or pigment with an hvlp or cup gun can be a piffling tricky, simply with exercise using this blazon of paint spaying equipment volition go easy. A HVLP system is great for spraying a diversity of business firm paints, primers and clear forest finishes. The terminate result is hard to indistinguishable with other equipment or transmission awarding.

Brainstorm by spending some time stirring and thinning the product to exist sprayed. Thinning is the catchy function. The consistency must exist thin plenty to produce a fine mist, atomization, but thick enough produce a practiced build or thickness of material.

If a paint is to sparse the colorant will carve up from the binders, floating on top. Yous will have to experiment a bit to get used to this idea; every product is a little unlike.

A good way to determine the viscosity is to utilize a make clean stir stick. Insert the stick into the material, pull out the stick and count how long information technology takes for the steady stream to intermission, plow into dripping. Count in seconds. I use twenty-25 seconds for Acrylic paint and Alkyd paints and 15-20 for oil base varnishes. This will take some practice. For greater accuracy and reliability purchase a viscosity cup. And e'er follow the articles instructions.

A viscosity loving cup is an inexpensive device used with an hvlp spray gun to measure out the thickness of paint or primer. Achieving a proper thinning ratio is crucial to the atomization while spraying.

Using a Viscosity Cup

Completely submerge the loving cup in the coating to be sprayed.
Lift the cup out of the blanket and brainstorm timing until the kickoff suspension in the stream of material coming out of the bottom of the loving cup. Measure in seconds, a stopwatch volition be helpful.
Consult the manual supplied by the manufacture for viscosity recommendations.

To practice with the hvlp spray gun use a piece of cardboard or other material that can be thrown away. Adapt the air force per unit area and volume co-ordinate to the guns didactics and plough off the material feed. When y'all pull the trigger only air, non paint will exit the tip.

At present pointing the gun at some cardboard slowly open the material feed and pull the trigger. You want a fine mist but a steady period of material. Keep the gun perpendicular and six-8 inches from the surface.

Filter Your Finish

Cleanliness or filtered paint/varnish is of the utmost importance for whatever paint sprayer simply HVLP units require a little extra care. Dispensable cone filters a the best for small amounts or for using cup-guns. These filters are cheap and worth having in whatever shop.

Make certain to e'er filter your cloth, primer paint and varnish, earlier spraying.

Adjusting the Spray Pattern and Volume

3 unlike spray patters are possible with most HVLP spray guns; round, vertical and horizontal. Although vertical and horizontal patterns are easy to sympathize, you need to be enlightened of the round patterns limitations. The round patters concentrates more material into a tighter space. Yous need to adjust the volume differently for the circular pattern.

Most HVLP spray guns have both air volume and cloth book adjustments. Generally, you desire to utilise the least or everyman material and air volume possible to minimize overspray and heavy looking finishes. This takes practise. I suggest practicing on cardboard. Cardboard is useful for getting the adjustments right earlier spraying any projection.

HVLP guns consume less air than conventional spray equipment and produce up to 50% less overspray. Since thin coats are being applied less material is required to achieve the final effect. These thin coats dry in less fourth dimension assuasive a completed project with a smooth stop in less time than any other application method.

An especially useful tool for spraying difficult finishes like interior wood stains and lacquer.

An hvlp spray gun is great for fine finishes and quite fun to work with. Since the paint to exist sprayed goes on in a fine mist you tin can take your time, have fun and achieve a cute finish.
