There are several types of sealant on the market that adhere to most surfaces, but you must above all base your choice on the application you will make of it. It is important to know if the movement of the wall will be high or low, what is the life cycle of the building and what is the necessary chemical resistance.
The NP1 sealant from Master Builders Solutions is the product we recommend. It is a one-component, primerless, sprayable, high performance polyurethane elastomer. It requires no mixing to adhere to many materials, including concrete and masonry ( adheres to fresh concrete as early as 72 hours after application) .
NP 1 is available in 12 standard colors to match a wide variety of common substrates and is paintable. The seal has a capacity of + or - 35% elasticity and is designed for places with frequent temperature variations. UL listed, it passes the 4-hour, 4-inch fire and water jet test when used with Ultra Block or mineral wool.
