Seam taping is an easy process
and an important step in properly preparing your surface before
applying Ames Coatings and Paints.
Why is it important? Hot and cold temperature changes will cause
a roof, wall, or deck to expand and contract. Over time, cracks
and leaks can develop. The purpose of seam taping is to provide
reinforcement over areas prone to splitting, such as seams or
joints, and create a “bridge” that ties the surfaces
together so water cannot seep through. Seam tape is used around
roof vents, on flashings, over cracks and gaps, along the seams
on metal or RV roofs, and in many other applications.

Lightweight Seam Tape
Do I use Lightweight
Seam Tape? The
process itself is similar to fiberglassing. You
will need a pair of scissors or a utility knife
to cut the tape. Use a 4” wide paint brush,
and your choice of Ames coating to embed the seam
tape into the coating.
1. Clean and Prepare the Surface. Be sure
surfaces are clean and dry. Caulk all cracks
greater than 1/8” wide with acrylic or
butyl caulking or patching compound.
2. With a 4” wide paint brush apply
a liberal coat of Ames’ Elasto-Barrier™
over the seam or joint about 5 to 6 inches wide.
Roll the seam tape into the wet coating. Take
care to smooth out any wrinkles.
3. Immediately brush a coat of Elasto-Barrier™
over the seam tape to completely saturate it
and fill any pin-holes. Allow to cure. An additional
coat is recommended. In most applications the
seam tape will be dry in about 2 to 4 hours.
