NanoROOF™ Caulk is a high-performance elastomeric sealant that adheres to masonry, wood, asphalt, metal, and vinyl, suitable for various roofing, window, door, siding, trim, architectural metal, and general construction applications.

It can be applied to masonry, wood, asphalt, metal, vinyl, and damp or oily surfaces, even in low temperatures.

It is ideal for filling joints and cracks wider than 1/16 inch, with excellent adhesion to most exterior substrates. For optimal results, joints should be a minimum of 4 times greater than the anticipated movement, with sizes from 1/4” x 1/4” to 1/2” wide by 3/8” deep.

Clean and dry the surface before application. Use a soap water solution, Xylol, or acetone for cleaning if necessary.

Apply the sealant with conventional equipment, filling the joint completely. Use an open cell backer rod to control joint depth and bond breaker tape in shallow joints to prevent three-point contact. Warm the sealant if temperatures are below 40°F, and avoid applying it on surfaces above 140°F.

Yes, the sealant can be painted after 24 hours. If using a relatively inflexible paint, allow the sealant to dry for 3 days before painting. It is compatible with any latex and most oil-based paints, though some paints may crack due to dynamic joints. Refer to the paint manufacturer’s specifications.

NanoROOF™ Caulk offers exceptional elongation and flexibility, expanding up to 800% with full recovery, superior ultraviolet resistance, and a non-stringing formulation. It is ideal for sealing around dormers, windows, doors, hips, rake edges, valleys, skylight frames, chimneys, foundations, siding, vent pipes, collars, gutter seams, ridges, sills, and wall flashings.

NanoROOF™ Liquid Flashing is ideal for sealing chimneys, roof panels, valleys, vents, shingles, flashing, gutters, foundations, retaining walls, doors, window sills, siding, thresholds, wood foundations, and wooden gutters.

No, it is not intended for traffic-bearing surfaces.

No, it is not recommended for use on polystyrene insulation sheathing.

Ensure the surface is clean, structurally sound, free of foreign substances, and dry, although moderate dampness will not interfere with adhesion.

 Yes, the sealant must fully cure until the solvent dissipates before allowing food processing or storage in the area.

Yes, but for maximum adhesion, clean the surface with a suitable solvent and allow it to fully evaporate before applying the sealant.

Yes, the sealant cures to a tack-free finish, is mildew-proof, and can be painted once fully cured.
