Industrial Blasting & Painting Nigeria — Surface Preparation and Protective Coating Systems
Karoch Engineering provides grit blasting, needle gun, and hydro blasting surface
preparation followed by multi-coat protective paint systems — for new fabricated steelwork, existing structure maintenance, and pipeline corrosion protection in Nigeria.
Surface Treatment That Survives What Nigeria Throws at It
Paint systems fail in Nigeria faster than anywhere in Europe — because they are specified for European conditions. Coastal salt, tropical UV, thermal cycling, and industrial chemical contamination all attack protective coatings at higher rates than temperate-climate specifications assume. Karoch Engineering specifies and applies paint systems designed for the environment the structure will actually operate in.
What We Fabricate
▸ Grit blasting — Sa 2.5 and Sa 3 (near-white metal) surface preparation to ISO 8501-1
▸ Needle gun descaling — surface preparation for maintenance coating of existing structures
▸ Hydro blasting — high-pressure water blasting for surface cleaning and paint removal
▸ Multi-coat industrial paint application — zinc silicate primer, epoxy mid-coat, and polyurethane topcoat systems
▸ Epoxy coating application — coal tar epoxy, glass flake epoxy, and fusion-bonded epoxy for immersed and buried service
▸ Fireproofing coating — intumescent and cementitious fireproofing for structural steel
▸ Maintenance repainting — inspection, surface preparation, and repainting of existing steel structures
▸ In-workshop and on-site application — both workshop-controlled application and site painting for installed structures
Surface Preparation Is Where Coating Systems Succeed or Fail
The most expensive coating system applied over inadequate surface preparation will fail in 2–3 years in Nigerian conditions. Karoch Engineering’s blasting team prepares surfaces to specification — confirmed by inspection before any paint is applied. The paint system is only as good as the surface under it.
FAQ
Fabrication Questions
Q: What blast standard do you prepare to?
A: Standard preparation to Sa 2.5 (ISO 8501-1) for most industrial paint systems. Sa 3 (near-white metal) for high-build epoxy and immersion service coatings. Confirm the required blast standard at the project scope stage.
Q: Can you repaint existing steel structures without dismantling?
A: Yes — on-site surface preparation and repainting of installed structures is standard practice. We contain grit blast or needle gun debris on site as required for environmental compliance.
