Why Do You Need to Test?

Sealers are sealers, after all, and selecting one should be an easy process, right? Unfortunately it's not that simple. There are many complex and conflicting reasons for choosing one sealer over another, and these reasons prevent a single sealer from becoming the "best" product for every situation. Often selecting a sealer requires a compromise between looks, cost, ease of application and performance. The first three factors are fairly straightforward and obvious, but performance is a complex issue that can't be easily predicted or assumed.

Testing is an easy and accurate way to verify that a sealer does what you expect it to do. Often the application method, the number of coats and other factors peripheral to the sealer itself have a strong influence on its performance. Relying solely on the recommendations of others and their subjective, second-hand information can lead to problems down the line. Unless you put a sealer through its paces yourself, you won't know its limitations or its capabilities, and more importantly, you won't be able to confidently communicate with your client. You can't set your client's expectations about your concrete and how it will perform if you don't know that yourself.

Setting expectations about how a countertop sealer will perform in the long run with regard to staining, etching, scratching, heat resistance and maintenance are vital to the end result and the key to long-term client satisfaction. Simply explaining to clients what a sealer is often doesn't provide enough information about how that finish will perform. Clients are then likely to form their own expectations, which may not match what you can deliver.

The only way to fully understand the capabilities and limitations of your sealer—and properly set your clients' expectations—is to test it. Testing is a simple, easy and realistic way to evaluate a sealer you're considering or to learn about the sealer's performance so you can develop language to use when speaking with a client.
