Common Concerns Answered
Paint compatibility concerns are noted; what is the recommended procedure?
Paint compatibility requires preliminary testing on a small, inconspicuous area to ensure desired adhesion and finish, as formulations can vary.
The tack-free time is longer than some alternatives; what is the implication?
The extended tack-free time allows for precise application and positioning of components, but requires patience before subjecting the joint to movement or stress.
Is removal difficult once fully cured if a permanent bond is not desired?
Once fully cured, this polysulfide sealant forms a very tenacious bond, making removal challenging if a non-permanent adhesion was intended; plan applications carefully.
