All about painting.



Masking materials

The masking process has as main objective the protection of certain areas of the structure or workpiece that we do not want to paint. Paint application by gun spray generates in the environment a cloud of paint, which is deposited in areas near the surface to be painted, this is the main reason why the process is carried out in disguise.

Also, using masking materials we avoid input or dust / foreign particles deposition, protect certain parts or areas of high exposure to heat during the drying process of paint, establish the contours and colours that have a certain design, etc...

In order to carry out this process of masking, have developed a range of materials and tools that facilitate this work, knowledge of each of these tools allow us to select the right material for each type of masking :

Masking paper

Paper has been and is the material most used to mask or protect areas not to paint, low acquisition cost and easy of placement on flat surfaces, make the paper a suitable material for masking.

The main characteristic to provide the paper used in the masking process is to resist the solvents and diluents containing in the paint and the possible manipulation efforts, on the other hand the paper selected must resist drying temperatures to which shall be submitted once painted the workpiece in order to accelerate the drying process. Kraft paper is a perfect candidate that meets all the requirements described above.

In the market we can find masking papers of different dimensions and shapes, with the presence of an adhesive tape which facilitate and reduce the operation time of masking.

Plastic sheet masking

The plastic sheet masking has been the technological evolution of the paper in masking, as well as the characteristics of resistance to solvents, temperature and handling, the main advantage of using these films is the easy adaptation to the contours, which is why they are suitable candidates to protect curved surfaces, corrugated surfaces, etc…

As occur with masking papers, the protective films are available in a variety of dimensions as well as the possibility of incorporating an adhesive tape to facilitate placement and fixation.

Masking tapes

Among the wide range of masking tapes on the market, we can classify them into three groups:

All masking tapes have as common features that have at least one adhesive sie, also exist in the market or double-sided tapes with adhesive on both sides, as occurs with the films and papers, the masking tapes have to be resistant to solvents from paints, to handling and drying temperature, on the other hand once the work is end the tape must be remove easily and quickly without trace of adhesive.

The fine masking tapes are masking tapes more flexible compare with the general or classic, allowing masking curved surfaces, inscriptions or logos.

Trim masking tapes consists of a rigid plastic part that inserted through the inside of the molding, as well as has adhesive part that is used to place the paper or plastic sheet masking, especially useful for masking of frames and windows.

Plugs and caps

The use of plugs for masking or covering of nuts and both plain and threaded holes, generally are made ​​of silicone because of its high resistance to solvents, temperature and handling, and ease of cleaning of the paint when dried allowing re-use it many times.

Masking rope

Masking rope are self-adhesive foam strips used in holes and openings, the purpose of masking rope is to prevent the penetration of the spray paint into the hole and stain the interior paint is not desired. This type of masking material is used on the edges of the doors, hinged covers...
