Whether we want it or not, it is necessary to paint the house or a room (whether it is a living room or a bedroom, a kitchen, a bathroom or a closet) to sanitize the space and redecorate it. The most uncomplicated painting works only require a change of finish, in particular, the application of a new layer of paint on the ceilings and walls. The operation is quite simple and can be done in a few days if we only summarize the application of the new paint coat.

Depending on the condition of the degradation of the surfaces and the complexity of the renovation, we may have the surprise that other works are needed for what it was like to be a simple painting. Let's see what it is about and how we can ensure a correct development of the works to provide us with superior quality and sustainability. Let's take a look at some distinct cases and the necessary operations, all of which have the purpose of applying washable paint, that the house painters in Denver recommend. Usually, the interior surfaces are finished with plaster and washable paint, but there are also houses doused with classic lime.

Finished walls with lime
Lime is not compatible with washable paint, and therefore it is necessary to remove it. This operation can be accomplished by mechanical procedures, with the gap, combined with a soapy water solution, with a rotating scraper, but this requires plenty of dust and does not recommend it.

Walls finished with huma
Huma is a fat-containing material that is sensitive to moisture. Because of this, washable paint cannot be applied over huma, but it is necessary to remove it from all surfaces where we want to apply the washable paint. Details can be found here

Walls finished with washable paint
Old washable paint can be covered directly with new paint if there are no dirty surfaces with grease that would not allow proper adherence, etc. Optionally, the old washable surface can be sanded easily to matt the surface, then strip and wash the walls. This alternative is an unpleasant operation due to the dust created, which is why it is rarely used where there is a need to eliminate some irregularities of the first start, the removal of some non-adherent areas.

Preparing the support
Regardless of the finishing, the preparation of the substrate is essential to obtain a perfect finish, as beautiful and uniform as possible. As a result of surface cleaning operations, we can see that the tile layer will require repair or restoration.

It is unnecessary to repair the gutter start to remove the pinches and splinters remaining from cleaning the surface or straightening specific areas. Before sanding the regions, it is necessary to clean and prime the surface with a deep primer (wall primer).

When we find that the initial trowel layer is brittle, it no longer adheres to the plaster/ concrete/masonry layer, etc. (generally, it sounds empty at a simple hammering, even with the finger or the gap easily enters the skein and instantly jumps) we will opt for the complete elimination of it. It is recommended to do so once the finishing layer has been removed, which would ease the operation.

After removing the debris, we will prime the entire surface using a deep primer (wall primer). This will be applied in a layer, with a brush or a broad brush to penetrate into all the pores of the material and to achieve the stabilization of the powder, consolidation of the support layer, excellent adhesion of the slab, etc. Depending on the flatness of the wall, we can choose:

- a filling and leveling tile if we need to load the surface more, this plaster is based on gypsum and allows application in a maximum thickness of 10 mm / layer; is a very strong mesh;

- a finishing tile if it is only necessary to level the surface and obtain an excellent surface - of a white, this white base cement base and allows a maximum thickness of about 2-3 mm / layer;

- applying the system composed of the two shades mentioned above, in the order presented, initially equalizing the surface and then finishing it with the finishing trowel.

Careful! Prepare a quantity of gleam that corresponds to the speed of execution, if you are not able to put the plaster into operation, it will dry out, and it is good to throw away.
