Common Concerns Answered
Is proper surface preparation required for optimal adhesion?
Yes, proper surface preparation is critical for achieving optimal adhesion. Failure to prepare surfaces adequately can compromise the bond strength and longevity of the sealant.
What happens if I don't tool the sealant within the skin time?
In warm, humid conditions, the skin time can be short, requiring quick tooling. If not tooled within this window, the sealant may not achieve a smooth, aesthetically pleasing finish, and subsequent layers or bonding may be compromised.
Is cleanup of cured Sikaflex® 295 UV difficult?
Once fully cured, Sikaflex® 295 UV can be difficult to remove, making it essential to manage application precisely and clean up any uncured excess material promptly before it hardens.
