Advantages and disadvantages of acrylic enamel
Acrylic paint contains acrylic resins and water. It is a polymer emulsion. Performance enhancing additives may be present. Thanks to them, the viscosity decreases, the paint becomes resistant to temperature extremes. In cold weather, the paint does not crack. With the help of additives, you can get a matte or glossy shine. The work is carried out on metal, concrete, wood.
The order of business
Before starting work, you need to remove the old coating. The surface must be clean, free of dust and dirt. Otherwise there will be no adhesion of the enamel to the material. Then apply a primer and let it dry. Only then apply the first coat of paint. After drying, the second layer is worn and, if necessary, the third layer.
The work is done by roller or sprayer (pneumatic or airless).

What is the difference
Which paint to choose? There is no single answer to this question. It all depends on what it's for. What will they paint? Exterior or interior work is planned. For painting a car, acrylic-based car enamel will be best. It adds shine to the car, making it more attractive. But if the motorist has money problems, you can put alkyd paint in one layer.
For painting wooden products it is better to take alkyd enamel. This paint is best used for coating exterior trim.
Acrylic differs from alkyd suspension in that it is hypoallergenic and does not have a toxic smell. Therefore, it is suitable for interior painting. It is best to paint a child's room with an alkyd paint and varnish product.
Is it possible to combine
Many lay builders want to combine the two. That is, apply on one enamel with another. Doing this is not strongly recommended. At first, everything can be beautiful and attractive. But after a short time such a coating will swell, bubbles will disappear. The paint will crack. This is due to the fact that the paint applied to the varnish does not adhere to the surface and begins to peel off.
For acrylic work, you need to prime the surface and then apply a coat. This is not necessary for alkyd suspensions. In addition, before starting work, it is imperative to remove the old coating. For this, sandpaper or grinders are used.
conclusions
After considering all the pros and cons, we can conclude that acrylic paint is still better and safer than alkyd paint. It will serve for over a year. But if the owners are financially limited, the service life does not matter, then you can take the second option.
