Everything shows the effect of time passing. Nothing lasts forever. Look at buildings as an example. They are subjected to harsh weather conditions, such as UV light, acid rain, dirt, and extreme shifts in temperature or moisture levels. Even masonry & stone needs sealer to ensure longevity.

Paint will degrade over time, so you will have to repaint it when it begins to look worn out.

First you need to prepare the surface and then you need to apply the coating. So sandblasting gives the right care needed for preparing the surface.

If you have a limited budget you might prefer to get out the ladder and scrape all the peeling paint off yourself. When considering a commercial building, using hand preparation is not practical. Sandblasting is an option that’s far more sensible. Sandblasting involves aiming a stream of fine particles at high speed at the target surface to be cleaned or etched. Sand is not used as frequently now as it was when the term sandblasting was originally coined, since it is connected to the lung disease silicosis.

There are many alternative materials that can be used to sandblast. Examples include steel grit, copper slag, powdered abrasives, and pieces of coconut or walnut shells. Concrete and metal can be cleaned by the method of shot blasting. This method mixes water into the shot while it is being blasted towards the surface. The mixture is re harnessed and processed so that it can be used again. Dry Ice is an additional state of the art material. The great thing about dry ice is that it evaporates, so that you do not have to recapture the blast material.

If the dry ice produces any water it must be reclaimed as there are huge fines for water runoff. Sandblasting is a technique that can be used to get a surface ready for painting or clean a surface that remains naked.
