One of the most critical elements impacting the performance, quality, and service life of a coat of paint is ground preparation. Surfaces have to be entirely clear of dust, grime, and oil and properly prepared to guarantee adequate coatings adhesion to the substrates, in order to get optimal results. Sandblasting and water blasting are two typical surface preparation procedures utilized by industrial painters nowadays.
Water blasting
Hydro blasting is a cost-effective, safe, and environmentally friendly approach to cleaning and maintaining various surfaces. Continue reading to learn about the most significant advantages.
- Water blasting can clean and prep a wide range of external painted surfaces without the need for solvents or the danger of releasing harmful particles into the air.
- Water blasting, unlike chemical-based scrubbing, produces no residue after, thus no washing is needed.
- Users of water blasting gear can regulate the pressure and swap between various fan nozzles depending on the job. For example, you can easily lower the pressure to eliminate dust, spider webs, and pollutants, and raise it to eliminate adhesive and multi-layered sealant systems. Reveal and tidy out fractures so that proper repairs could be made. Available surface stomata to produce suitable profiles for the implementation of new barrier protection sealant systems.
- Surfaces are left clean, chemical-free, and suitable for re-use upon water blasting (after they dry out completely).
Before trying to utilize water blasting equipment. Read a Step Guide to Power Washing the Proper Way since the wrong approach or use of the gear can cause severe damage and significant erosion of surfaces.
Sand blasting
Sandblasting is among the most frequent metal surface preparation procedures. But it may also be used to remove debris, dust, and old painting from a variety of surfaces.
There are two types of sandblasting: 1) Moisture sandblasting. Which uses a high-pressure stream of water combined with sand or even other gritty material; 2) Dried sandblasting, which uses highly compressed air mixed with abrasive particles. Both techniques provide the following advantages:
- Sandblasting is a faster, simpler, and faster approach to cleansing and preparing diverse surfaces for repainting than water blasting.
- Sandblasting can be customized to do a wide range of tasks, from mild cleaning (expelling dirt, dust, gravel, corrosion, and old paintwork) to deeper cutting (molding, surface preparation, and polishing surfaces).
- Because sandblasting is more forceful than sandpapering, specialists can prepare areas in hours rather than days.
To ready metal for repainting, power washing or steam washing may be required in addition to sandblasting. Dry sandblasting is also riskier than wet sandblasting because it can produce potentially harmful dust clouds. Sandblasting operations in some sections of Florida (such as Miami Beach, Miami, and Coral Gables) require special approval from the county or city.
Various painting tasks entail a variety of circumstances and unique requirements. Before deciding on one blasting process over another. It’s critical to review project parameters, substrate state, technical information sheets, and application techniques. When in doubt, experts should be consulted for advice.
