How to choose emulsion paints for indoor painting?
Emulsion paints (in other words dispersion) make now the largest and most popular product group to paint walls and ceilings. They have replaced used so far traditional glue and lime paints. Their solvent is water and a binder aqueous polymer dispersion.
These paints during drying emit only water vapor, which is extremely important when it comes to health and comfort applications (smell). Their additional advantages are high performance, versatility, ease of use and resistance to mechanical damage.
Paint released for sale must meet many requirements of Polish Standard. Most important of these are: opacity, water vapor permeability, viscosity, density and mechanical strength of the coating. The latter qualifies the product to one of three groups, depending on their response to the washing and scrubbing. And so:
Type III means that paint is resistant to abrasion on dry.
Type II is a paint resistant to wash.
Type and is a product resistant to scrubbing.
Paint manufacturers use more and more modern technologies by improving their products. Today in the market there are available paints of an extremely high resistance. An example may be Śnieżka SATIN, which is five times more resistant to wet scrubbing than other latex paints (according to PN-C-81914). The guarantor of this is research carried out by the Testing Laboratory. Więcej informacji - kliknij tutaj...
So how do you choose the product best for our interior? What should you be aware of ?
By selecting the paint remember:
-for new, not yet painted plaster surfaces or those made of gypsum plasterboards, it is worth choosing better products, resistant to wash (type I or II). Before painting, use primer.
-If the walls have been painted before with paints of unknown origin and you have reasons to believe that there are many layers, it is not recommended to use expensive easy scrub paints of highest performance. Poor ground does not provide them with appropriate conditions to ensure that paint can fully demonstrate their own properties. In such cases it is better to use type III paints (cheaper) and expect its shorter durability time .
How do you assess the ground?
At the beginning, it is a good idea to have a careful look at the wall. You can perform a simple test. At the place where the coating seems to us uncertain, a painting tape must be firmly fixed and then remove it quickly. If remains of old paint stay on the tape, this means that the surface adhesion is low and it is better to apply paint type III. If the tape remains clean and the test was performed in several randomly chosen places, this means that we can reach for better products (type I and II).
It is best , however, to remove old and poor paint. This means perhaps a much larger amount of work, but end result will remain much longer, and the use of best paint ensures not only the perfect looks of walls, but also an easiness of cleaning, not to mention the fact that another renovation will be postponed by even a few years.
- -Spaces which are not exposed to dirt or abrasion can be painted with cheaper paints (Type III).
- -If we are changing walls color, it is better to choose a more expensive product of high hiding power to avoid multiple surface painting.
In rooms exposed to water, such as kitchen and bathroom, use paint dedicated to these rooms because they have additional properties which protect them against excessive bacterial and fungal growth. Wiecej informacji - kliknij tutaj...
The choice of emulsion paint to paint room is most often a compromise between the condition in which painting walls is going to be done, expectations as to the result, the strength of new coating and the size of your wallet.
