Generally, if the joint size falls within 3/4", single-component sealant is a good choice.

If the joint size is greater than 3/4", two-component sealant is highly recommended. In addition, as two-component sealant shows great curing properties in larger joints, therefore, it is highly recommended for larger joints.
