Self-adhering alkali-resistant fiberglass tape with mesh opening 2.5×2.5mm and weight of 55gr/m2. Necessary for strengthening horizontal and vertical drywall and cement board joints. Apply immediately after the first coat during taping, when using the joint compound for drywall D-67. Coat over the tape with a second and final coat. Its application ensures resilient joints and protects from capillary cracks or bursting. Ideal for spot strengthening concrete cracks as well as for at-length applications of joints between floors and walls, before the application of cementitious waterproofing products.
