SILICONE SEALANT VS ACRYLIC SEALANT
First, we should know its purpose. Silicone sealant is based on silicone polymers and forms a tough flexible rubber. There are 3 types of silicone sealant, but for roofing and external uses the neutral curing silicone's are used due to its superior adhesion and weatherproofing properties. In addition to being used on surfaces sensitive to acetic acid. So flexible is good because structures do have movement. Silicone has a longer lifespan than your acrylic sealant. Silicone is considered a cut above when it comes to being weather resistance and maintaining its weatherproofing properties longer.
Acrylic sealants are based on acrylic polymers. When it comes to roofing acrylic sealants is not ideal as acrylic sealant are traditionally used internally. Such as an economical filler and it is paintable with most paints. Acrylic sealants doesn't have as long of a lifespan as Silicone sealants especially when it comes to moisture/water conditions and temperature conditions.
