Do you want to know what kind of paint to use outside? Each outdoor paint type has its own special elements that make it suitable for a specific project. Keep in mind that there is no single type of product ideal for every need. Moreover, outdoor paints are made up of ingredients based on the type of substrate and its conditions. Let’s try to be a little more clear about this.
Best Outside Paint – Outdoor Painting and Optimal Cycle
The choice and application of a specific type of finish is important to avoid making mistakes. First, it requires three important things:
- Study of the substrate, for example, it is necessary to study its nature and characteristics
- The operations to restore the integrity of the substrate
- Application of preparation and priming products, which improves the substrate’s adhesion
Once you complete these 3 essential procedures, it is possible to move on to choosing the appropriate type of finish. There may be external factors that may influence the cycle. One of these is, for example, the type of building, and the relative materials you will use.
What Kind of Paint to Use Outside: Painting For Exteriors and Organic Solutions
The first type of outdoor painting consist of organic finishes. These types of paint include acrylic paint, siloxane paint, and acrylsiloxane paint.
The Best Paint to Use Outside: The Best Solutions
Acrylic outdoor paint is a product with low absorption and equally low breathability. Moreover, acrylic paint adheres perfectly to substrates by physical contact. Any substrate that has characteristics (even minimal) of porosity and roughness can be considered suitable for this type of outdoor painting.
On the contrary, acrylic paint is not suitable if the substrate is not dry. The reason is water slows drying and the resin is not able to penetrate. In addition, acrylic paint solutions are easy to apply.
A siloxane outdoor paint has low absorption and high breathability characteristics. Furthermore, it has siloxane resin, whose work is to prevent water coming from outside. Going on, it also allows the external evaporation of water vapor. Other advantages of siloxane products are that they are compatible with the substrates and have excellent resistance to freezing.
Acrylsiloxane paints for outdoor use have less than 40% siloxane resin. They also have a low water absorption and good level of breathability.
Outdoor Paint and Mineral-Based Solutions
Mineral finishes are another type of outdoor paints. Silicate paint and lime paint belong to this category of solutions.
This paint develops adhesion to the substrate through chemical reaction. You can apply it on mineral substrate. Thanks to the uniform layer created with the substrate, silicate paints guarantee the longevity of facades over time. Also, they have an excellent resistance to atmospheric agents.
The lime-based solution is the other type of mineral product for outdoor painting. Adhesion occurs by chemical reaction between the free lime of the product and the lime contained in the substrate. The substrate must therefore have characteristics that allow the free lime to melt.
Lime based products are distinguished by their excellent vapor permeability and application only on mineral substrates. As with silicate paint, with lime-based paint a blurred effect is obtained, without compactness and color homogeneity.
