Research study: qualifying offshore-wind repair coatings — and the surface-prep step behind them (RepaKORR)
The BMBF-funded RepaKORR project studied damage, accelerated ageing and offshore application procedures for wind-structure repair coatings — with grit-free mechanical surface prep...
Why Spot Blasting Can Limit Coating Performance
Patch repairs fail at the rim: how spot blasting creates abrupt edges, feathering failures and halo corrosion - and how controlled mechanical...
Blast-Less Surface Prep Tools for Coating Companies
The contractor's guide to blast-less preparation: what it does to bids, which SSPC/ISO specs it meets, the kit a crew needs, and...
Surface Preparation for Heavy-Duty Coatings: A Substrate-by-Substrate Field Guide
The world's best coatings deserve the world's best surface preparation. A high-performance protective system — epoxy, zinc-rich primer, siloxane topcoat, a NORSOK...
Surface-Tolerant Coatings: When Perfect Prep Isn't Possible — and Why Prep Still Wins
In new construction, the heavy-duty answer is a three-coat system — inorganic zinc-rich primer, epoxy intermediate, polyurethane topcoat — over blast-cleaned steel....
What Makes a Coating Specification Enforceable
A specification is not a recommendation, a guideline or a suggestion. It is a formal, legal document that tells the contractor specifically...
Generic Types of Protective Coatings: A Working Guide to the Chemistry
Protective coatings are classified by the generic chemistry of their resin. Knowing the families — what each is good at, what it...
Coating Inspection: The 11 Hold Points That Prevent Most Failures
Inspection is the only way to verify that the specification requirements for a coating and its application have actually been met. It...
Surface Preparation of Concrete Before Coating: Contaminants, Defects and Methods
As with steel, the success of any coating system on concrete is highly dependent on the surface beneath it. Concrete, though, brings...
The True Cost of Coatings: Why Cheapest Per Gallon Costs More Per Year
Procurement compares coatings by price per gallon. Engineers who own the asset for twenty years compare them by installed cost per square...
Stress Corrosion Cracking: What It Is, Where It Occurs, and How Coatings Prevent It
SCC requires three conditions to be present simultaneously. Eliminating any one of them prevents SCC:
Galvanic Corrosion: How It Works and the Role of Zinc-Rich Primers in Protection
When two dissimilar metals are connected in an electrolyte, they form a galvanic cell — an electrochemical cell in which the difference...
MIC Corrosion: What Microbiologically Influenced Corrosion Is and How Coatings Address It
MIC in carbon steel and other ferrous metals is primarily associated with three categories of bacteria:
Intumescent Coatings: What They Are and What Surface Preparation They Require
Intumescent coatings contain three active ingredient types that react in sequence when exposed to heat:
Industrial Coatings: Types, Systems, and Surface Preparation Requirements
Two-component epoxy coatings are the most widely specified industrial coating technology globally. They consist of an epoxy resin component (Part A) and...
Corrosion Resistant Coatings: Why Surface Preparation Determines Whether They Work
Corrosion resistant coatings protect steel through one or more of three mechanisms:
Performance Coatings: What They Are and What Surface Preparation They Require
Performance coatings is an industry term for coating systems formulated to deliver measurable, long-term protection in service environments that standard
Soluble Salt Contamination: Why It Causes Coating Failure and How to Test for It
Soluble salts in the context of steel surface preparation are ionic chemical compounds — primarily chlorides, sulphates and nitrates — that dissolve...
