Installation

|
 Cut to length desired.
The chop saw is the key to fast clean cuts, that allow for flush abutments. When making straight cuts Trim Tech can be cut with hand nippers such as (wiss) wire cutters. A carborandum blade is used. The Dewalt 12 inch compound radial arm saw is preferred.

 When cutting picture frame 45 degree cuts, allow 1/2" or more to cuts, adding the 1/2" to cuts allows for proper spacing of forms to insure nose wires are at least 1/4" away from window or door frames. To insure proper spacing use 1/4" spacer held between window or door frame and nose wire of the Trim Tech form, as shown in picture.

Nailing or wire tying.
 For flat stock such as 2x4 through 2x12 sizes use 3 1/2" inch galvanized roofing nails. 2x4 and 2x6 sizes can be nailed or wire tied at up to 24 inch centers, all other wider shapes should be nailed at 16 inch centers. When applying wider shapes use two nails wide as you would with lumber. Look closely at some examples of nailing and wire tying. Picture to the right shows an example of nail spacing and wire applications.
As you can see the picture on left shows two nails spaced about 21" apart on that 2x4. When nailing with wider shapes use two nails wide as you would do with lumber.
Pressure nailing or tacking on the forms.
Only nail on with slight pressure, being careful not to drive home or over nail. Nailing or tying only is only needed to hold forms in place until it receives the first coat of mud. The mud is what secures Trim Tech forms to the wall. When installing belly bands always use a string line to insure straightness. When attaching potshelves or 4x4s or wider shapes us 5" galvanized nails, and up to 6" nails depending how wide the shapes are.
In all cases put nails through wire openings any where on the face of the forms that allow the wider roofing nail head to grab wires, the pictures below gives you an example.

To button up large openings created when using 4x4s or potshelves and other wide stock, cut small pieces of expanded metal and wire tie to ends, or use scrap corner aid as the following pictures will give you the idea.

For concrete or block walls or metal stud framing order Trim Tech with nailing flanges. Use self tapping screws for metal studs applications.
For block and concrete the nailing flanges provide a way to attach with concrete nailing guns, and some cases non-toxic hot glue guns can be used to attach with glueing at 6" to 8" centers. Note if hot gluing the plastering process should be done with in 7 days. He are a few picture examples of hot glue used to attach to block wall.

 Plaster application
Spray (gun applied) or hand apply scratch coat to walls and Trim Tech forms, as you would do ordinarily. Use a brush to sweep off excess mud from face of Trim Tech, and also brush the inside corners. Inside corners always has an excessive amount of mud in that area, and the brush forces the mud under the hollow shape of the Trim Tech encapsulating the existing metal lath to the side leg wires of the Trim Tech. The is Key to proper installation. When browning repeat this process, except ofcorse you would be using a trowel and darby instead of a brush. Shave off all fat or excessive mud from nose wires with trowel. Allow to set up and hard float. Allow to cure and apply 1/8" stucco over all Trim Tech nose wires and forms.
Block wall and concrete mud application. Normally block and concrete walls usually only receive a skim coat of mud, about 3/8" thick. When using Trim Tech it is preferred to apply a scratch coat to the Trim Tech forms and feather the joints into the field. Same procedure with the brown coat, as the Trim Tech pre-shaped lath forms require a little more thickness of mud than the typical skim coat. A journeyman plasterer already knows this technique.

 Trim Tech will not twist, warp, swell, leak, or need to be repaired later. Trim Tech is environmentally friendly, fire resistant, and much faster than foam to install.
