Zinsser 2681 Filler Repair Caulk 1 Gal Clear Acrylic

Product Description

The ZINSSER 2681 is a clear, acrylic filler and repair caulk packaged in a 1-gallon can. It is designed for interior gap filling, crack repair, and surface preparation work in residential and light commercial settings. The acrylic formula provides a flexible, paintable seal suited for use on drywall, trim, baseboards, and similar interior substrates. With a coverage rate of 400 square feet per gallon, it is well suited for production-volume work where efficiency matters. The clear finish blends into most surfaces and accepts topcoats without significant adhesion issues. Painting contractors, drywall finishers, and general contractors are the primary installers of this product.

The ZINSSER 2681 is intended for indoor applications only. It is appropriate for residential construction and remodeling projects as well as light commercial interior work. Typical use cases include sealing joints between trim and drywall, filling minor surface voids before painting, and caulking interior transitions where a clear, low-visibility bead is preferred. The 1-gallon can format is suited for contractors working on larger jobs where a standard tube-size caulk cartridge would be inefficient. Maximum operating temperature is 32 degrees C.

Installation Notes

Application is typically performed by painting contractors or drywall finishers using a caulk gun compatible with a 1-gallon container or by brush and applicator tool depending on surface type. Ensure the substrate is clean, dry, and free of loose material before applying. Allow adequate cure time before topcoating per standard interior finishing practice. Work in adequately ventilated spaces even with indoor-rated acrylic products.
