How do you determine the best type of coating for repainting a block or concrete building?

An apartment or warehouse owner has different expectations to the bottling plant or frozen storage manager. We do our best to inform the customer of what they can reasonably expect given their particular situation.

There is insufficient information to legitimately answer the original question posed. What is the existing paint? What is its condition? How long did it last before deteriorating? Is there any unusual pattern to the deterioration? What is the condition of the substrate? What is the current moisture migration, both liquid and vapor? What are the environmental conditions? What cleaning processes are currently used? How often? Will they continue in the same pattern? What is the desired/expected lifespan of the new coating? What condition changes will determine "end of life" for the new coating? Et cetera.

We both want a recommended system to perform well with consideration for useful life and overall cost. With manufacturers sometimes limited to recommending the products they produce, the responsibility of the specifier would be to analyze a client's substrate, environment, timing, monetary constraints, visual desires and then match the best system or systems to the project. Also important, in my view, is to present a comprehensive explanation in understandable terms to the specific client as to why the specific coating or system of coatings is being recommended. Who prepares the surface and applies the coatings can also determine the success or failure of the best of materials.

I was asked a similar question about a different type of asset. When we get questions like this, we explain that the wrong questions are being asked. I'm sure we'll get a variety of lengthy responses to this question asking a myriad of questions, which is appropriate. It doesn't matter what substrate or asset you're trying to protect, the question should be, "what process will you be using to determine an optimal solution to our problem." Far too often, people look for a material solution without fulling understanding the condition of the asset, its environment and what the client needs. They are quick to sell their product first, without first understanding. It's the old, "Ready, fire, aim." And then everyone's surprised when there are massive coating failures and the premature end of service life.
