"Metal Mastery: Weekly Insights from Pym & Wildsmith" ⚙️ - The Science Behind Shot Blasting and its Role in Pre-Treatment Shot blasting is one of the key methods we use at Pym & Wildsmith to prepare metal surfaces for coating. This high-pressure process involves propelling abrasive materials at the surface to remove rust, mill scale, and old coatings, leaving behind a clean, smooth, and slightly roughened surface—perfect for adhesion. But there’s more to shot blasting than just cleaning; it’s about creating the right texture to ensure the next layer bonds effectively. At Pym & Wildsmith, we adhere to industry-standard blast cleaning grades, including SA1, SA2.5, and SA3, to meet the specific requirements of each project: • SA1: Known as light blast cleaning, this standard removes loose surface contaminants and is ideal for surfaces that don’t require a full, thorough clean. • SA2.5: This is the most commonly used standard for preparing metal surfaces, achieving near-white metal cleanliness by removing nearly all mill scale, rust, and other contaminants. • SA3: This is the highest standard, where the surface is blasted to a visually clean, white metal finish, ensuring maximum adhesion for high-performance coatings. Why does this matter? Without the proper surface profile, finishes can fail, leading to costly repairs and replacements. Our shot blasting process is carefully calibrated to suit the specific material and finish you need. For clients seeking durable, long-lasting results, this preparation step is non-negotiable. 🔴 Pym & Wildsmith, Bramshall, Staffs - 🌐 https://lnkd.in/dF94kY5x #MetalMastery #ShotBlasting #SA1 #SA25 and #SA3 #PymandWildsmith #Staffordshire
