Seam Tape

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


  How 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.
  Seam tape and Elasto-Barrier

Step 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.

apply Seam Tape

Step 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.


Step 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.
