Dictionary of Moisture Protection & Restoration

CHOOSE THE RIGHT SEALANT Too often, the contractor or installer will depend on past experience with a specific sealant regardless of the requirements. “It always worked before – I never had any problem with this material”. Well, this is a sure way to get in trouble! Most contractors and applicators do not have the technical knowledge to make the decision on the proper products to be installed in order to meet all requirements. However, they do know what is expected from a sealant under specific conditions. The input from the manufacturers is critical. After all, they are the ones you are going to call if your sealant fails. When you call them, be precise and truthful. Manufacturers cannot help you unless you give them the proper information: 1. Joint design and size. 2. Substrate (concrete, stone, metal, etc.) 3. Condition of the substrate. 4. Geographic location and weather conditions. 5. Expected performance from the sealant. 6. Your experience doing these types of projects. 7. Are they willing to warranty their sealants? 8. Then you can ask the price. Generally, the contractor does not get the credit for the success of a sealant, but will get the blame if it fails.
