Types Of Paint For Fronts, Facades And Exteriors

A list of paints and coatings to paint facades, exterior walls of homes or buildings, which must be waterproof and resistant for adequate protection.

Keeping the facade and all the exterior parts of a house painted is important, not only for an aesthetic matter, but also to prolong the good condition of the base surface.

That the walls remain during the years without a coating that protects their components will favor their deterioration, causing cracks, humidity and detachments. The maintenance of the outer surface able save restoration work deeper in the future.

It is not convenient to apply an interior paint on exteriors, it does not have the necessary components to provide good protection, and the durability will be much lower. The products that can be applied to maintain the good condition of the surface are very varied. The existing diversity depends on the components used, the desired protection, and the money we are willing to pay. Let's see some of the most common.

Plastic and acrylic paints, acrylic coatings

Basically, plastic and acrylic paints are very similar, and in many cases they are often confused with each other, being used for the same purpose. The small difference is the resin with which they are formulated, which gives advantage to acrylic paints for exterior surfaces due to its greater resistance to the weather, although at a slightly higher cost.

The plastic paints can be a cheaper option, but not a bad choice. Currently manufacturers use additives that improve their performance, making them a good material to protect outdoor walls.

Elastomeric coating, elastic paint

The term elastomeric refers to polymers with elastic properties that are an essential component of this type of paint. Therefore, when it is necessary to waterproof and coat a support with small cracks, elastic paint is one of the best options.

Depending on the manufacturer, these coatings may have higher or lower elastic properties, but generally cover porosities, cracks of up to 1mm, and also take care of the house from rainwater. The paint is suitable for application on plaster, concrete, brick and plaster.

Silicone resin paint, silicone coatings

The greatest quality of silicone resin-based paints is to form a microporous film, which prevents the absorption of rainwater from the outside. But this also allows the removal of the moisture contained inside the wall, which is repelled in the form of water vapor through the film.

The paint can be opaque and of different colors, or they can be transparent coatings. The latter are widely used in the protection of exposed brick walls, stone and concrete. The application of this material prevents the formation of fungal stains, soot and excessive adhesion of dust. Many of the coatings called transparent hydrophobic are no more than silicone resin paints.

Silicate paints, silicate coatings

Silicate paints are special for facades and exteriors thanks to their durability, resistance to weathering and humidity. It is a mineral paint whose binder is potassium silicate, which adheres to surfaces of mineral origin such as bricks, concrete and plaster by chemical reaction. They are suitable for application on walls with residual moisture since they do not form a film, and are permeable to water vapor allowing transpiration to the painted surface.

Although they are not suitable for application on wood, plastics or resin-based paints, lately manufacturers have developed silicate paints that adhere to other plastics and synthetics.

Coatings or paintings Pliolite

This type of paint is composed of a special resin called Pliolite, originally developed by the American company Goodyear. Pliolite resin (synthetic rubber) gives the paint great properties to protect outdoor surfaces. They are currently manufactured in solvent base and water, although it is not available in all countries.

What stands out to the Pliolite paintings is a very good penetration in the support and excellent adhesion. They form a microporous film that allows perspiration. It has a perfect resistance to water, sun, and weather which gives it durability even in extreme conditions.
