ADVANCED SILICONE TECHNOLOGY

FOR RESTORATION

BEFORE

AFTER

Joint sealant failures remain a common – and harmful –

issue over a building’s lifespan. Repairing joint sealant failures

traditionally involved failed sealant and surface preparation

– often resulting in substrate damage and huge labor costs

(especially for exterior insulation and finish systems, or EIFS).

Pecora’s Sil-Span Preformed Silicone Profiles provide an

alternative to the traditional method of repairing failed

sealant joints. Sil-Span “bridges” over the joint to waterproof

the building envelope while maintaining the original

aesthetic of the substrate. – saving you time and budget.

Sil-Span is made of a specially formulated high-molecular

weight, low-modulus silicone compound which is extruded

into preformed strips and custom shapes. This advanced

silicone technology is easy to apply, comes in many widths

and colors, adheres to most common substrates, and will not

stain adjacent surfaces. It’s design properties suit a variety of

construction applications including expansion joints.

Sil-Span can also correct failures in areas of the building

envelope which prove difficult or almost impossible to

replace or reseal through conventional methods, including

metal curtain walls, stucco, skylights, roofing details, reglets,

coping stones, and flashing details.

THE BEST WAY TO MANAGE COMMON SEALANT FAILURES AND INCREASE YOUR BUILDING’S LIFESPAN.

3. Clean area with alcohol and prime as necessary

5. Apply Sil-Span to the prepared joint substrate

2. Use a straight edge to mask width of required Sil-Span

4. Apply Pecora adhesive/sealant to both sides of the joint

6. Remove excess caulk, trim ends, and terminate with cap bead of Pecora adhesive/sealant

Sil-Span’s design properties suit a variety of construction

applications including expansion joints. Sil-Span also

accommodates glass-to-glass and glass-to-metal

glazing details including skylight or glazing repair.

As the bond between Sil-Span and the substrate,

Pecora’s full line of non-staining silicones provide

outstanding adhesion to many substrates including

rough textures such as EIFS and exposed aggregate.
