This is an example of a very transparent suspended ceiling.
Ceilings are the most overlooked feature of any room. Suspended ceilings, on the other hand, provide an opportunity to make a ceiling more noticeable. This is accomplished by making it more dramatic with appealing, unique features. These ceilings are installed on a suspended grid at a level somewhere between the actual roof framing and at some point above the floor. They are made up of panels which can be painted or otherwise enhanced to make them a more noticeable, aesthetic part of any room. Installing these lath and plaster ceilings is a multiphase task.
Instructions
1. Gather the suspension system components for the ceiling. Choose the plaster base panels. Look for fire-resistant, gypsum core with liner paper on the backside. Select the 1/2 inch, 3/8 inch or 5/8 inch thickness. Use the pre-measured ceiling area to determine panel size, and use panel size to calculate how many panels you will need.
2. Suspended ceilings can be canvasses for unusual lighting and other decoration.
Use the same area calculation to know how much mesh framing material to purchase. Include double V joint, casing, corner bead, rolled channel, perforated L runner and both sizes of furring clips. Sketch out the suspended ceiling area, if it will help with your calculations.
3. Select the basecoat plaster. This is probably the most important part of producing a quality ceiling finish, so choose carefully. Consider the properties of a standard plaster to which you add the sand when mixing on site versus a light weight plaster with the aggregate already added to which you add only water at the site. Each is suitable depending upon the preferred method of application and the desired finish.
4. Medallions of various shapes and sizes are often used to enhance .
Choose the finish plaster next. Decide if you want a quick set or slow set type, and whether you need a gauging type or moulding type based on whether or not you plan to add ceiling ornaments. Get the moulding type if you want to cast ceiling medallions and other features.
5. Use the L runner and CR channel stud to construct the framing into which the metal lath and plaster will be installed. Use the ceiling area calculations you did earlier to lay out this framing. Attach the framing to the ceiling joists in accordance with ASTM, American Society for Testing and Materials, C841 standards and codes.
6. Suspended ceilings are plastered much in the same way walls are plastered.
Apply the first coat of plaster onto the installed metal lath using a trowel. Use firm, steady pressure to establish a bond with the plaster and the lath. Go back over the first coat immediately and build the sufficient base coat thickness. Leave the base coat rough and porous to give the finish coat solid adherence to the base.
7. Give the base coat time to get set but not completely dry. The finish coat will go on much better if the surface is still damp, but not too wet. Use a trowel to apply the finish coat to the finish coat in long sweeping motions just like you applied the base coat.
