DURO-LAST ® DURO-CAULK PLUS
Description:
Duro-Caulk® Plus is a one-component,
non-sag, elastomeric, neutral cure silicone
sealant. It is available in white, gray, tan and
bronze colors. Duro-Caulk Plus is formulated
for use with all Duro-Last roofing system
details that require sealant.
Duro-Caulk Plus is unaffected by most
atmospheric conditions and will typically cure
within 48 hours. It is formulated to bond to
substrates such as PVC, glass, aluminum,
steel, plastic, ceramics, concretes, and wood.
Its high-tack properties ensure a
weather-tight seal around penetrations,
terminations and drain inserts.
Material Safety Data Sheet:
1. Product Code: 1029 WF
Application:
1. Be sure that surfaces receiving caulk are
clean, dry and free of any oils, greases, or
coatings that may interfere with adhesion.
2. Apply using a standard caulking gun. Do
not open the cartridge until you are ready
to apply the sealant.
3. Apply the sealant using consistent,
positive pressure to force sealant into the
joint, creating a bead approximately 3/8
inch (0.37 mm) in diameter.
4. Tool the sealant to create a concave joint
shape to shed water and ensure
maximum adhesion and coverage. Dry
tooling is recommended. DO NOT use
soapy water or other liquids when tooling.
5. Sealant may be applied below freezing
temperatures.
6. Do not apply to surfaces that bleed oils or
solvents.
7. This product is not paintable.
