Review: quality product - glad I found it - used this for a repair that needed waterproof and permanent - this applied on easy and so far 100% resolved issue! I used AI to recommend product off desertcart after uploading to AI a photo of the damage and this is what it recommended.
Review: Professional grade sealant. - Before I retired, my company was excellent at ceiling water leaks. Sika was the best product in areas exposed to ultraviolet light. I recently used it when installing a new skylight on my RV. Knowing that it’s difficult to clean up, I blue taped all edges and had rags with solvent nearby. The job went very smoothly, I was impressed how easily it adhered and spread evenly. Cleanup turned out to be no problem for me.

### ⭐⭐⭐⭐⭐ Great caulk!
*by J***R on May 26, 2026*

This stuff is robust. It’s easy to apply and finish, looks great and holds up to standing water (so far). On the pricier side but you get what you pay for, it should hold up!
