SECURA LATH® SECURA LATH INSTALLATION GUIDELINES PRODUCT DEVELOPMENT Secura Lath was born out of necessity. After the development of AMICO Security Mesh, specifiers requested that we develop a product that would provide a superior penetation barrier for plaster and stucco applications. After years of lab and field testing, Secura Lath was ready for market and was introduced in 1994 at the Construction Specifications Institute trade show. Since then hundreds of thousands of square feet of Secura Lath have been installed to the satisfaction of owners, designers, specifiers, and contractors. PRODUCT...

SECURA LATH® SUSPENDED CEILING FRAMING INSTALLATION The Supporting Framework AMICO Secura Lath serves as a structural base for the stucco or plaster, and the framing structure is the foundation for the lath. Because Secura Lath is somewhat stouter , the framing system has been strengthened and should be installed as follows: 1. Use 8GA 0.1620-inch (4.12mm) galvanized hanger wire for suspension of hangers. 2. Mechanically anchor hanger wires to the ceiling or sub-floor system, by use of drilled and inserted anchors or pre installed loops embedded in the concrete. See ASTM C1063 for other acceptable...

SECURA LATH® Lath Preparation Secura Lath may be cut with abrasive metal cutting blades in a circular saw, with a power shear , and for small areas with hand held channel nippers or bolt cutters which have been ground to fit the diamond shaped openings. When cutting ASL with power tools one should wear goggles, mask and ear protection, so as to avoid injury. Suspended Ceiling SECURA LATH INSTALLATION ASTM C1063 requires that metal lath be lapped a minimum of ½ inch (12.7mm) on the sides and 1-inch (25.4mm) on the ends. ASL should be installed with the long way of the diamond (long way of the...

SECURA LATH® Note: It is imperative that all openings are cased with X-66 casing bead attached to the Secura Lath to completely isolate the plaster membrane from all protrusions and dissimilar material. Ceiling Perimeter Expansion Many designers are concerned by the 3/8-inch (9.5mm) space which remains between the edge of the casing bead and the wall with ceiling applications.This could easily be a hiding place for contraband. HoweverAMICO recommends , the use of a light 30Ga or less wall angle, 1½” x 1” (38.1mm x 25.4mm) to close this gap. Refer to the details on pages 8 and 12. Due to the flexibility...

SECURA LATH® the stucco membrane at a rapid rate, causing the stucco to become weak and brittle. Allow sufficient time between coats to permit each coat to cure or develop enough rigidity to resist cracking or other physical damage when the next coat is applied. Contact EIFS finish manufacturers for information on recommended curing times for the brown coat of stucco, before the application of the acrylic finish. Additives It is our recommendation that AR (Alkali resistant) fibers be used in the scratch coat to give extra strength to the stucco. We also recommend that an acrylic modifier product...
