A surface accepted at SP 10 in the morning may no longer meet that grade by afternoon. The blast-to-coat window is a specification item, not a scheduling detail. https://maintenanceblueprint.com/en/standards/how-to-read-tds/ https://maintenanceblueprint.com/en/standards/how-to-read-tds/ Wed, 19 Aug 2026 00:00:00 GMT A Technical Data Sheet (TDS) is a legal document, not a marketing brochure. Always check Volume Solids for true cost calculation, Pot Life for application limits, and the exact testing standards (ASTM/ISO) used for performance claims. https://maintenanceblueprint.com/en/mining/slurry-wear-mechanisms/ https://maintenanceblueprint.com/en/mining/slurry-wear-mechanisms/ Sat, 15 Aug 2026 00:00:00 GMT Three mechanisms damage equipment in slurry service, and they call for opposite properties. Sliding abrasion favours hardness, impact favours toughness, erosion-corrosion favours chemical stability. Selecting for the wrong one produces a material that fails faster than what it replaced. https://maintenanceblueprint.com/en/standards/sspc-surface-preparation/ https://maintenanceblueprint.com/en/standards/sspc-surface-preparation/ Wed, 12 Aug 2026 00:00:00 GMT Surface preparation determines up to 80% of a coating's lifespan. Understanding the exact difference between SSPC-SP6 (Commercial) and SSPC-SP10 (Near-White) prevents over-spending on unnecessary blasting or under-preparing for severe environments. https://maintenanceblueprint.com/en/corrosion/cui/ https://maintenanceblueprint.com/en/corrosion/cui/ Sat, 08 Aug 2026 00:00:00 GMT Corrosion under insulation happens when water reaches the steel and cannot leave. Insulation does not cause it — it hides it, holds the water against the surface, and delays discovery until the wall is already thin. The coating under the insulation is the barrier that matters, not the cladding over it. https://maintenanceblueprint.com/en/standards/iso-12944-corrosivity-categories/ https://maintenanceblueprint.com/en/standards/iso-12944-corrosivity-categories/ Sat, 08 Aug 2026 00:00:00 GMT ISO 12944 divides environments into six corrosivity categories (C1 to CX) and defines durability ranges (Low to Very High) to help engineers specify protective coatings that match the exact environmental stress of the asset. https://maintenanceblueprint.com/en/standards/sspc-sp10/ https://maintenanceblueprint.com/en/standards/sspc-sp10/ Sat, 08 Aug 2026 00:00:00 GMT SSPC-SP 10 requires removing all visible oil, grease, dust, dirt, mill scale, rust, coating and oxides from the surface. Light shadows, streaks and discolouration from residual staining may remain on no more than 5% of each unit area. It is the grade most commonly specified for immersion and severe atmospheric service.
