Application
Clean off dirt, loose paint, rust, oil, and grease. Let the surface dry. Apply with a standard caulking gun. In cold weather, warm the tube to room temperature before use. At about 50–70°F, Dicor lists these approximate cure times: skins over in 5 minutes, waterproof in 4 hours, 80 percent cured in 48 hours, and fully cured in 30 days.
Keep the sealant away from heat, sparks, and flame, and ventilate the work area. Dicor’s sealant page includes additional first-aid and fire guidance.
Use Dicor’s non-leveling sealant where the surface is vertical. Confirm the roof material before ordering.

Resealed the seam on my 1999 horse trailer. Worked very well. I cleaned off the old sealant with a wire wheel on my grinder then wiped down with acetone, taped off both sides of the joint about an inch or so and then ran a fat bead. I used a small putty knife to sort of help level it out a bit and it came out perfect. Pulled the tape and had a nice clean straight edge.
Shipped exactly what I ordered. Service and price was great. Would order again
It's a great product, a very good price, delivery was right on time, thanks.

Keeping seams on the roof of an RV from leaking is vital. Nothing does that better than Dicor's lap sealant. I used this sealant for years and never had an issue.
I recently used this self-leveling lap sealant for a few outdoor sealing projects, and I’m extremely impressed with its performance. The application process was easy and mess-free. Once applied, the sealant spread smoothly and evenly, filling gaps and seams without any effort on my part. It’s perfect for roof seams, RVs, and other areas that need a watertight seal.
