Blasting & Painting
Surface Preparation and Coating Removal
We have developed extensive knowledge and practical experience on the various techniques available for surface preparation and associated coating application methods to meet the required industry quality standards.
At DEYYAR, we have set out to develop a highly trained workforce including Omani’s with the capabilities to meet all our client’s surface preparation requirements and have recently augmented our experienced project team with a team comprising of National Association of Corrosion Engineers (NACE) certified coating inspector and highly skilled and experienced blasters and painters. We offer a range of services from the pre-engineering phase through to project close-out, including project management, surveying and planning, reporting, recommendations and technical support.
Our USP is Appropriate Solutions with Cost Effectiveness.
We have a range of preparation techniques, equipment and facilities to handle any industrial painting, protection and removal or preservation project. We have wholly Owned Facilities and Equipment.
DEYYAR has an extensive range of the latest technology surface preparation equipment, encompassing abrasive (wet and dry) blasting, mechanical (power tools) methods, soda blasting and UHP water jetting (hydro-blasting).
Our equipment resources afford us the capability to undertake all sizes of projects and provide the most effective tailored solution to meet the project requirements.
Abrasive (Grit Blasting using Garnet) involves the use of compressed air and an abrasive medium and can be used for surface removal of previously applied coatings, corrosion deposits, etc., on all types of surfaces including steel.
Blasting abrasive surface is traditionally recognized as one of the fastest and most effective form of surface preparation and coating removal, establishing a good sound-working surface to promote the adhesion of a specific type of paint or coating.
We own and operate a large inventory of equipment ranging from blast pots /kettles to specialist portable abrasive systems providing controlled surface internationally recognized standards.
The most commonly referred to standards are Society for Protective Coatings (SSPC), Corrosion Engineers (NACE), National Association of Swedish Standards (SA).
Mechanical/Power Tool Cleaning
Mechanical/Power Tool cleaning involving the use of power tools such as needle guns, chipping hammer, sanders using abrasive discs. All hand tools comply with the latest legislation and when used in compliance with “safe operating procedures” safeguards the operative.
Cost effective in preparing small areas for inspection or cosmetic repairs. It gives enhanced control for sensitive areas.
It’s an acceptable alternative where it is not possible or practical to use abrasive blasting or UHP.
Soda blasting is a mild form of abrasive blasting in which sodium bicarbonate particles are hit against a surface using compressed air. It has a much milder effect than sandblasting.
Soda blasting doesn't hurt chrome trim, glass, rubber, aluminum, or fiberglass, yet it has no problem pulling off paint, filler, undercoating, and seam sealer.
We have special soda blasting machines and are well equipped to handle any kind of paint removal from soft metals, and fiberglass.
UHP Water Jetting/Blasting
UHP Water Jetting/Blasting is extremely versatile and both an effective and environmentally friendly way of preparing a surface for coatings application.
Operating at up to 40,000 psi (2,750 bar), the use of UHP water jetting technology enables us to remove any coating and soluble salts, taking the substrate back to its original profile, and unlike other “traditional” surface preparation methods, ensuring the surface is completely contaminant free.
Another advantage that UHP water jetting / blasting holds over abrasive blasting is the effect on the environment. UHP water jetting excludes the use of abrasives, minimizing the resultant waste stream and by introducing containment and filtration the resultant washings can be effectively reused.
Furthermore, abrasive blasting creates several environmental and health and safety issues by creating dust. Consequently, issues are created with the associated clean-up operations and air borne contamination arising from the operation which could affect others out with the immediate work team who may not be wearing appropriate PPE.
Typically, UHP technology is used for the surface preparation of large surface areas such as tank. internals and externals, bulkheads, decks, walkways and helidecks, and with no “spark” this enables UHP to be widely used in hazardous and extreme environments.
DEYYAR has the equipment, the experienced operatives and the techniques for surface preparation using UHP Water Jetting/Blasting.
Coating Applications, and Preservation:
Paint breaks may be caused by a variety of circumstances. The paint may be too thin or may have degraded through proximity to the environment. The coating may be porous and may not form a complete barrier. Or the paint may have been applied incompletely or improperly. If the surface was not properly cleaned before applying the paint, then breaks will occur since the paint will not adhere well to contaminated surfaces or to blisters.
You can use the best coating/paint products in the world, but if the surface is not prepared properly before the application, premature failure of the coating and deterioration of the substrate metal is inevitable. Our Coating Specialists study each project and determine the optimum approach to surface preparation based on site specific conditions such as materials, existing corrosion, humidity and other environmental conditions.
In addition to the financial cost associated with replacing badly maintained coats of paint, the coatings applied on such surfaces are usually lower in quality due to adverse application conditions. 75% of all coating failures are attributable to deficient surface preparation or to improper application of the paint. These failures lead to downtime's during which the tank cannot be used while it is being repaired. The downtime and loss of facility production can lead to potentially staggering costs.
DEYYAR has the capability to apply conventional or specialist coatings in accordance with manufacturers and client specifications.
Having prepared the surface using one of our applications, we can apply the required coating to provide an effective barrier to combat corrosion significantly increasing the life of the asset and reducing the required time on planned maintenance project. Capabilities extend to the application of a range of high-tech coatings and composites such as:
- Industrial Epoxies, Alkyds and Urethanes.
- Non-Slip Helideck and Deck Coatings, Screeds and Tiles.
- Tank Vessel Linings including Glass flakes.
- Internal Tank coating
- Antifouling Coatings
- Turnkey Painting Programs
