Appears to be a good product - would buy again.

Used this product to seal the vents on the roof of my trailer. I recommend that you use this product on a hot day to ensure the sealant is more liquid otherwise it tends not to spread evenly and sets-up to quickly. It did a good job of sealing however not the best looking job - time determine how well this product lasts.

Hard to beat
Reviewed in the United States on July 14, 2025

Dicor is the only lap sealant I use on the roof of my RV. It is a well known and reputable brand and I have never had any issues with application or failure. It works well on the roof of my Crossroads RV and the quality is hard to beat. It applies easy over the old Dicor and settles well into all the cracks and imperfections. The new white looks good and dries quickly and I have even applied while it was sprinkling rain

Great product.

The product arrived but whoever put the caulk tube in the box smashed in down and broke the tip off the tub. It was almost unusable to use
however I made it work with much difficulty. The product itself is awesome and sealed my RV roof from leaks.

Works well and is a well known sealant. Easy to use . Make sure you prep surface properly. One tube doesn't go far so order more than you think.
