All tools require a certain relationship and the presence of special handling skills. Therefore, working with paints and paints and paintopult, you should take care of both the correct use of the tool and about your own security.

Working with the spray gun requires compliance with the basic requirements:
- you need to take care of a good ventilation of the room;
- if the tool is used outdoors, it is necessary to work with him in calm dry weather;
- before painting parts for the car, you need to provide special conditions, since explosive substances are explosive in car colors, and there is a caustic smell.
Before starting work, it is necessary to strain the paint and fill it with a bench of the kraskopultum (not to the end). Diluting the composition should be according to the instruction, since the viscosity of the material is directly dependent on the quality of work. Make sure that the lid fits snugly filled with banks and create a good seal.
The use of the spray gun and pulevizatora:
- used for painting with adhesive or lime compositions;
- designed for painting large surfaces.
It is best to work with a manual variant of the collapse. Such a tandem will maintain the required pressure in the system, and you will avoid diverse sublists, properms and other color defects.
How to paint paint
Painting with spray paint includes a number of stages:
1. Preparatory work
When using mixtures on the basis of organic solvents in the room, an unpleasant smell is formed, and explosive and poisonous evaporation occur. Therefore, if you work where there is no special equipment, use water-based paints.
Recommendations and Precautions:
- take care of high-quality air ventilation;
- his stream should be created with your back, pass around the product with which you work in the spray direction, and determine the aerosol fog and smell;
- if you work on the street, select the darkened area, which is closed from the wind, carrying dirt and dust;
- pay attention to the readings of the hygrometer and the thermometer;
- it is recommended to work at temperatures from +15 to + 30 ° with humidity up to 55%;
- having equipped the room for painting large projects, put a fan opposite the door or windows in an inpanded place;
- install a bright lamp to control the apparel of the paint;
- make a product available from all sides.
2. Preparation of the composition for finishing
The air that passes through the sprayer performs several functions:
- sprays the composition for the smallest drops;
- bringing the resulting fog to the product.
That is why, due to the small pressure in HVLP systems, more viscous compositions - enamels alkyd, latex paints - need to be diluted stronger than water-based compositions.
Next, it is necessary to determine the period of time for which the composition follows from the barrel, and compare it with the manufacturer's recommendations. You can choose the desired viscosity of paint with a viscometer or an experimental way.
This is done as follows:
- fill in a tank a certain amount of the mixture;
- install the airflow and fluid flow to the maximum;
- create the greatest torch width;
- scroll to a trial small area and check the quality of spraying;
- if the paint is not sprayed or sprinkles with large drops, add 5% solvent in the bar. So should be done until the composition does not begin to spray similarly to the fog;
- testing undiluted and diluted paint should also, also reduce the fluid flow and the width of the torch;
- when the limit is achieved, fix the ratio of proportions and the name of the manufacturer.
Recommendations:
- water-based mixtures work well when adding to 10% water;
- mixtures on organic solvents can be diluted by more than 50%;
- in case this is not enough, replace the paint nozzle to another with a large diameter that comes with another needle.
3. Work with sprayer:
- initially, it is necessary to determine the order of applying paints to the surface. The product is recommended to divide into the zones "A", "B" and "C", where the zone "A" will be the most significant site;
- work with zones should be in reverse order, in order to create the disappearance of surplus;
- press the sprayer's trigger is necessary at the edge of the surface to be painted, and not in front of it;
- in the passage process, the sprayer is recommended to hold on the same distance without tilting it;
- should not be moved arcuate;
- the trigger is released only when the torch's jet comes out for the opposite edge of the surface;
- strips are recommended to apply in the direction of the tree fibers;
- the edge of the first strip should be overlapped by the following;
- be sure to look through the application of paint during the braid lighting, which allows you to identify defects;
- if you notice an uncrowded plot, immediately spray the composition on it, moving the paintopult faster than usual;
- on the vertical surface, it is not recommended to spray the paint with a thick layer, it is better to apply several thin layers.
How to configure the paintopult:
- to adjust the flow of air and liquid, suspend the sprayer vertically above the piece of newspaper and keep at a standard distance from it;
- press on the trigger and keep it while the stains will not appear on the spot;
- adjust the settings;
- next, turn the air nozzle for the formation of a torch, which is similar to the fan, and practice in applying overlapping strips in all directions;
- to create a uniform coating, move the tool at one speed while holding it at a certain distance.
Problems that may occur when applying paint:
1. At the edges of the spots arose
In this case, there was an overflow surplus relative to the fluid flow. Just reduce it or use a more viscous composition.
2. Things arose under the middle spot
There was surplus of the flow of fluid relative to the air flow. Take the needle and reduce the fluid flow through the nozzle.
3. Light stain looks dusty
In this case, a too viscous composition for spraying was formed. It is necessary to add a little diluent.
Painting with paint walls
Since low temperatures and high humidity are the main enemies of water-level paint, then before painting walls, it is necessary to ensure that the conditions correspond to these parameters:
- the temperature should be from + 10 ° to + 30 °;
- absent strong drafts;
- the room was well ventilated;
- humidity did not exceed 85%.
Recommendations:
- the tool must be filled with paint intended for the collapse:
- use personal protective equipment;
- paint need to be applied smooth, but at the same time rapid movements (stops should not be);
- pneumatic spraying is made from top to bottom either from left to right;
- it is not recommended to create wave-like movements;
- the paint is applied at a distance of 300 mm from the wall with a certain angle of inclination of the tool;
- regularly control the fluid level in the barrel;
- paint predetermined, it must be homogeneous and sufficiently liquid;
- it is best to make coloring in several thin layers, which completely overlap each other;
- the next layer on the wall is applied only after drying the first;
- if the first layer was applied to the left, then the second must be applied from top to bottom.
Painting the ceiling of paintopult
Thanks to the use of collapse, the quality of the ceiling color will be much higher compared to roller and tassels.
Recommendations:
- in order for the composition to be evenly, you need to withstand a certain length of the jet, which is produced by the tool;
- required distance to 700 mm;
- color is better made perpendicular to the surface of the ceiling;
- the ceiling is covered by the second layer only after drying the first;
- collect the circular motions in one pace;
- it is not recommended to linger on one site.
How to care for the tool
Recommendations:
- the cleaning of the sprayer may differ from different models, but in any case, you must first disconnect it from the turbine and by pressing the trigger, give the residues of the liquid to the colorful tank;
- then, from the tank, pour the paint into the jar and rinse it together with the rubber gasket using a solvent;
- cleaning is created in accordance with the type of composition for applying. For example, if shellac, nitroquac or an alkyd varnish was used, the solvent used for dilution is poured to half the tank and is sprayed into another container to its complete devastation;
- next, wipe the hose and remove the remains of the solvent with soap water, which is passed through the nozzle;
- air nozzle can be cleaned inside with toothpicks;
- apply a thin layer of lubricant, which is recommended by the manufacturer.
