Dicor 551LSW-1 Non-Leveling Lap Sealant, White, 10.3 Oz, RV Roofing

Good sealant with no sag

This is one of those “buy it every year without even thinking about it” products—and for good reason. My boyfriend swears by this non-leveling sealant for the camper, and at this point I trust it purely based on his loyalty alone. If something keeps making it back into the cart year after year, you know it’s doing its job. We haven’t used this specific tube yet, but past experience says it holds up, does what it’s supposed to do, and saves us from bigger headaches down the road. Five stars for consistency, reliability, and for keeping the camper in one (non-leaky) pieve.

Perfect Value fo Rv Roof Repair nothing better than dicor

This tube works well for what i needed. I run a small gym and bought it for the staff break room roof and a leaky vent over the showers. Two small drips after a storm were driving me nuts. I cleaned the area, laid this down thick around the vent and seams, and it grabbed fast. No sagging, just stayed where I put it. next day we had hard rain and the ceiling tiles stayed dry, which saved me from replacing them again. I like that it’s bright white so I can see exactly where I’ve sealed and what still needs attention.

I love Dicor but the shipping didn’t work. It was placed in this large box without anything to keep it from bouncing around. So, the nozzle broke off making it unusable. Amazon offered a full refund so I’m satisfied.

This was recommended from major rv manufacturers. Used this on my grand design imagine. Worked great for edges and vertical seams and joints. Purchased the white and the clear colors to match application.

Perfect product for resealing our RV roof. Exactly what we needed.

Handy to have

Easy to work with.

Easy to use and does what it’s supposed to do

Works well for sealing the roof vent/ fan on my camper.

Fast shipping. Great product. Have always used Dicor products on my rig and very satisfied

I bought both the self levelling and non sag versions. The self levelling worked great on the flat surfaces. The non sag, when used along the drip edge of the roof, ran significantly and made quite a mess. I installed at about 20 degrees Celsius, but maybe it should be installed in cooler temps. Id likely find a better solution for the vertical and transition edges next season.
