A paint system can never render proper results until proper surface preparation is employed. This is because the quality of the paint used and surface that is to be painted determines the duration of the paintwork that is how long will it last. Removal of rust, scale, dirt and other contaminants such as salt, grime and old paint residues are an example of active surface preparation that facilitates the longevity of the paint.
What is Surface Preparation And Why is It Important
Surface preparation is getting rid of any previous contaminants and residues from any surface prior to any beginning of any action over it. If it is coating that is to be performed on a surface, choosing right surface preparation machines & tools is important as the integrity and the service life of coating will be greatly affected by the surface preparation.
It is observed that more than 80% of coating failures occur as a result of improper surface preparation. For instance most of the paintable surfaces include those made of copper, concrete and aluminium and it is important to render suitable protective measures to prevent them from corrosion. Such measures or in other words, appropriate surface preparation methods are opted on the basis of factors such as surface itself, environment, coating material and expected long-life.
Concrete And Suitable Methods For Its Surface Preparation
There are various methods for surface preparation and their choice depends upon certain factors. The most primary factor is the surface itself. For example, concrete is the most widely used artificial material which is also susceptible to chemical attacks. Adequate surface preparation measures include inspection, decontamination, establishment of surface profile and repair of surface irregularities. Methods such as use of detergent scrub and low pressure water, grinding, abrasive blast and steel shot blasts are used.
