Waterproof water-based paint: features of choice

Everyone at least once in their life faced with repair work, and the question always arose about the choice of material and tools, because there is a huge selection of paint and varnish mixtures. Today, the most common is water-based paint. It is designed for finishing various surfaces. Let's take a closer look at this paint and varnish composition.

The basis for the water-based paint is water and particles of polymer substances. The type of mixture depends on their quantity and properties.

Before buying paint, be sure to pay attention to its composition, consumption, viscosity and storage conditions.

It depends on the incoming components where and how the water emulsion can be applied:

• Viscosity is the ability to dilute paint with water. It is measured using a viscometer.
• Paint consumption depends on the viscosity of the material and the method of application. When using a brush, it is 40-45%, and when using a spray gun, it is 20-25%. On average, the consumption of this material is small - 250 g per 1 sq. M.
• The total drying time is about 20 hours, and sometimes less (all depending on temperature and humidity). Store the paint can in a cool place.

The water emulsion has become popular for its properties.

• It is an environmentally friendly and safe material that does not have a pungent odor.
• In addition, this paint is harmless to the body.
• It can be easily removed from various tools and surfaces using a soapy solution.
• The advantage of waterproof paint is that it dries quickly. It takes about 2 hours, after which the next layer can be applied. Of course, the drying speed is directly dependent on the air temperature. The lower it is, the longer the composition dries.
• Large selection of colors.
• To obtain the desired color, it is enough to add a certain dye.
• It is easy to use, easily adheres to any surface.
• This paint can mask small cracks in the surface.
• It is inexpensive.

There are practically no drawbacks to this paint. However, it can be used at temperatures not lower than +5 degrees. Another disadvantage lies in the fact that the composition contains a large water content, therefore it is not recommended to cover metal and glossy surfaces with such paint.

There are two main types:

• Waterproof or moisture resistant.
• Heat resistant or silicate.

There are several types of heat resistant paints:

• For temperatures from 80-100 degrees Celsius, paint based on an alkyd or acrylic component is used.
• For a temperature of 100-120 degrees, a material is used, which is based on epoxy resin.
• For temperatures of 200-400 degrees, a paint based on ethyl silicate or epoxy resin is used.
• At a temperature of 400-600 degrees, paints and varnishes are used, which include special silicone resins.

The choice of paint depends on the job you want to do, as well as on the degree of incandescence of the material.Heat-resistant compounds are suitable for painting fireplaces, barbecues, radiators or stoves.

This paint and varnish material is perfect for work both indoors and outdoors. It can be used for finishing in areas with high humidity: in the bathroom or in the kitchen. It washes well, fits perfectly on any surface: plaster, brick, concrete, wood or drywall.

Depending on the composition, water-based paint is divided into several types:

• Mineral.
• Silicate.
• Acrylic.
• Silicone.

It contains cement and slaked lime. This paint is used for any interior work with concrete and brick materials.

The composition includes liquid glass and colored pigments. Suitable for both indoor and outdoor use. Silicate paint is resistant to temperature extremes and moisture. It has a long service life (up to 20 years).

This paint is the leader in the construction market. It is in demand among both professionals and inexperienced craftsmen. Acrylic resins included in the mixture have a significant advantage over other types of paint and varnish mixtures.

Acrylic paint is used for finishing walls and ceilings, as well as other types of work:

• Perfect for concrete, brick and plaster building facades.
• Well suited for painting wood, metal, plastic and glass.
• Protects the surface from corrosion.

Sometimes latex is present in the composition. Thanks to this component, the paint resists moisture better. The painted base can be safely washed without fear that it will be washed off with water.

Acrylic paint with the addition of latex can be used to close small cracks in the substrate. The layer should not exceed 1 mm. In this case, the period of its drying (at home temperature) will be several hours.

The main component of these paints is silicone. This version of the mixture will be indispensable for a damp room, as well as in rooms where systematic wet cleaning with the use of cleaning agents is needed. Such opportunities are provided by the latex included in the paint.

This paint is considered the most expensive because of its water repellency and vapor permeability. It can close small cracks in the base. This allows you not to level the surface in advance.

Water-based paint is easy to tint. You can do this yourself. Many people use this method in order to save money, because the price of a white mixture is much lower, and there are much more opportunities when choosing a color.

You can achieve the desired shade on your own:

• Calculate the paint consumption as accurately as possible (with a small margin), since you will not be able to achieve the same color again.
• We add color to the composition in small portions, stirring constantly.
• If it seems to you that the desired shade has been achieved, do not rush to paint a large area. First, test the composition on a small, inconspicuous area, and then wait until it dries completely so that the color can show itself.
• After a satisfactory result, move on to larger volumes.

The choice of colors must be done very carefully. In small rooms, it is better to use light shades, since such a palette visually expands the area.

If you paint the walls in dark colors and the ceiling in light colors, then the room will look narrow. This method is used with low ceilings. Do not use more than two colors in the same room.

Using a brush increases paint consumption. It is better to use it for work in hard-to-reach places, and for large areas it is worth buying a roller and tray. Here you also need to take into account what material the tool and the fur coat are made of.

For stucco and rough surfaces, it is better to use a roller with a long nap, and for a smooth base, a short fiber is suitable. The tool should fit freely in the tray so that it is as convenient as possible to roll out the emulsion. Also, the roller should not be immersed in the solution more than a quarter.

If the paint rolls poorly, then you can dilute it with water, but no more than 10%, otherwise the composition will lose many of its properties. It is necessary to roll the mixture on the wall with the same pressure in order to avoid the appearance of stripes and joints. The coating should be applied in several layers to avoid cracking.

This paint is considered a universal coating. It can be combined with any materials. If there is a need to replace the finish, this is not a problem. Just treat the surface with a 1: 1 glue and primer solution. After the solution has dried, you can safely glue the wallpaper.

To be completely convincing, it is permissible to test the coating after treatment. We glue the newspaper onto a small area, wait for it to dry, and then try to tear it off the wall.

Oil paint coatings are common in stores today. Previously, such formulations were popular and were used everywhere. Water-based paint is incompatible with this coating, so it is best to remove the old finish.

They remove it in several ways:

• Mechanical. Remove paint with a spatula or sandpaper.
• Chemical. Remove with solvents.
• Thermal. Cleaned by heating the surface. When the old paint is swollen, it can be removed from the substrate with a spatula.

Consumers respond positively to water-based paints. Most buyers are pleased with the ease of their application, environmental friendliness and the absence of unpleasant odors.

It upsets people only that not all bases can be painted with such compositions due to the water base, as well as their incompatibility with some finishing materials, such as oil paint.
