Our take on the Dicor 501LSW-1 Self-Leveling Lap Sealant, White, 10.3 Oz, RV Roofing

Dicor 501LSW is a self-leveling lap sealant in a 10.3 oz tube for RV roofs. It flows out on horizontal surfaces to seal roof edges, vent pipes, air vents and screw heads, and stays flexible as it cures. It is formulated for EPDM rubber roofing and also bonds to PVC, TPO, aluminum, wood, vinyl, galvanized metal, mortar and concrete. RV owners use it for resealing and touch-ups because it is sun-stabilized and will not stain the roof material it touches.

Pros
  • Self-leveling formula spreads smooth on flat roof areas
  • Sticks to EPDM plus PVC, TPO, aluminum, wood and metal
  • Stays flexible after curing
  • Sun-ray stabilized against discoloration
  • Will not stain the roofing material
Cons
  • Only self-levels on horizontal surfaces, so vertical seams need a non-sag sealant

  • Cures slowly and skins over before full set
  • White color may not match every roof

Questions and answers

Can I use it on a vertical seam?
No. It is self-leveling and runs on slopes and vertical surfaces. Use a non-sag lap sealant for vertical seams and edges.
Does it work on TPO and PVC roofs?
Yes. It is formulated for EPDM but is also compatible with Dicor DiFlex II, Tufflex PVC and BriTEK TPO roofing.
How long does it take to cure?
It skins over within hours but fully cures over days, depending on temperature and humidity. Keep the area dry until it sets.
How much area does one tube cover?
A 10.3 oz tube lays a bead of roughly a quarter inch, enough for a few vents and screw heads. Larger roofs need several tubes.
Does it stain the roof?
No. It is sun-ray stabilized and will not stain or discolor the roofing material it is applied to.
Can I apply it over old sealant?
Yes, after cleaning off loose and peeling sealant. It bonds to cured lap sealant as well as to the roof surface.
