Luan Plywood Ceiling Installation


Luan Plywood Ceiling Installation 


Attaching will be with construction adhesive and nails. Depending on type luan  plywood you can go over studs directly or you may need to go over drywall if its thin like paneling. I saw this done once where the fasteners were incorporated into the design.

When you use black lag bolts with allen wrench sockets. Each panels had finished edges, painted black. Some panels were about 2'x3' if I recall correctly. and had about a 1.5" space between each.  They were shimmed down from a main ceiling by about 1.5".  main ceiling, or sub ceiling if you will, was also painted black.

Consider the panels were a pre-finished mahogany wood. It looked really neat. I considered doing this in my basement. There are also beadboard options, in sheets or boards, that look nice. Bottom line - This can be a real architectural feature or it can be a red flag when you go to sell, depending on how its done.

If you just want to take up luan plywood to cover some problem and avoid mudding thing you may be going down a wrong path. If you are doing it for design reasons then go for it and make it nice.




Using Luan Plywood as a Ceiling

Step 1 - Find the Ceiling Joists

Use the stud finder to locate all ceiling joists and mark the location with a pencil. Mark the joist by snapping a chalk line across the ceiling. The luan plywood will be installed perpendicular to the joists.

Step 2 -  Luan Plywood Installation

Glue the precut plywood in place using panel adhesive. Apply the adhesive to the luan plywood in a thin serpentine patterned line. Place luan  plywood on the ceiling pushing it against the edge. Use the pneumatic nail gun to put the luan plywood in place. Place the nails where you marked the ceiling joist.
Continue this process for each luan  plywood panel, using a rubber mallet to butt the panels as close together as possible.

Step 3 - Wood Molding

Place construction adhesive on the back of the precut wood molding. Align the molding with the edge of the ceiling. Use finishing nails to fasten it in place.

Step 4 - Sanding and Prep

Cover all nail holes with wood putty using a small putty knife. When the putty has completely dried, use sandpaper to smooth any imperfections in the wood and the putty. Use a soft cloth to remove any dust from sanding.


Strenghten Beams Using Luan Plywood


How to Strengthen Beams Using Luan Plywood 

By adding a luan plywood on top of  both sides of the beam, it can provide what home renovators refer to as shear strength. This type of luan plywood fortification is also commonly used on the exterior of frame buildings to add accumulative strength to vertical support studs spanning across the structure.


Measure the width of the beam at the point where two parts of the beam intersect or are joined together at any point.

2 Cut four pieces of luan plywood the same width as the beam on a table saw. Cut them parallel to the grain of the luan plywood.


3 Mix the powdered resin glue with water according to manufacturer's directions. Liberally brush one side of two pieces of luan  plywood with the glue using a paintbrush. Place one strip on each side of the beam, centered over any intersection or joint.

4 Shoot staples through the luan plywood pieces 2 inches apart randomly down the length of the strips with a staple gun to secure them the sides of the beams.

5 Paint two more pieces with glue. Place them on top of the other two pieces. Shoot staples through them just as you did the first two.


Wait 24 hours for the glue to dry before handling the beams.


Using Luan Plywood as a Ceiling Finish

Have you thought about using Luan Plywood as a ceiling finish? Well there are low quality plywoods ceilings that you can use, such as luan plywood. Here is an idea to use. 

Here is a video with a brief instruction as to installation.






Instructions on Installing Luan Plywood Ceiling 

    • 1
      Using a stud  locator through the drywall ceilings to locate the joists points. Then chalk a line to pin point the length of the position in each of the joists. from here install luan plywood over drywall and/ or firmly to ceiling joists. .
    • 2
      Measure at 90 degrees across the joists from the wall, to the center of the joist. The ends of two adjoining pieces of luan plywood must center on a joist. Use a table saw to cut the luan plywood to exact sizing.
    • 3
      Measure and cut a two-by-four stud with a miter saw for support on the opposite end of the luan plywood where it butts into the wall, if required. Screw it flush to the inner portion of the joist using a drill/driver and 3-inch screws.
    • 4
      Install one sheet of 1/4-inch  luan plywood across two sawhorses for drywall installation. Install one sheet luan plywood for open joist installation. Luan  Plywood typically has two faces, A is the premium face. The back, graded B, may have small defects. The A side should be facing down.
    • 5
      Sand the edges lightly with a hand block and 100-grit sandpaper to remove splinters, high spots, debris, chips or irregularities -- but don't sand dips in the edges. Check the thickness along the edges. Issues associated with luan plywood can include uneven seams due to irregularities in manufacturing. If you notice irregularities in the thickness, mark it. Use the irregular edge against a wall.
    • 6
      Use construction adhesive to the joists and/or blocking. Raise the luan  plywood to the ceiling using a drywall. Install it perpendicular across the joists. Push it into the corner, tight against the wall. Shoot 1½-inch staples, spaced 12 inches apart, through the luan plywood into each joist and on the blocking if applicable.
    • 7
      Repeat measuring, cutting and installing luan plywood and blocking where required. Fit each piece in succession, ensuring that both ends are centered on joists.
    • 8
      Staple 1/4-inch-by-1½-inch-by-96-inch pieces of pine lath or batting centered along each seam using 1-inch staples and construction adhesive. Use  lath with  luan  plywood. Saw them to length as required with the miter saw. Butt adjoining pieces together. Saw pieces to length using a miter saw.

Getting Rid of Smell Odor from Luan Plywood

Here are some quick and easy tips for getting the odor and smell out of Luan Plywood. 



 1) One way to get rid of the smell from Luan Plywood is to use  Approach which you can obtain from online retailers. This product is water based, therefore it does not have any harsh abrasives which will damage the finish on the wood.

b) Apply or Spray it on the wood, when it has had time to set, you can wipe it down, just make sure to get thorough coverage on your project.



2.) Another option is to go to the  hardware store in the in the home products and cleaning section. You should see a solution that as it dries it kills the odor. These solutions a re usually the ones for cat spray and urine. Spray a minimal amount on, you do not want to lift the luan, and leave it open to the air to dry.


3.) You can uses a spray  can branded  Oust, in the home cleaning section of the grocer or hardware store


4.) Some people use  three charcoal briquettes into powder and put it in a container, set the container in the box and after a week or so the odor will be gone.


5.) Use the same technique using bakling soda

Luan Plywood versus OSB Which is Best?

Luan Plywood: Most of us are familiar with the general nature of luan  plywood. But homeowners who don't work with luan plywood a lot may not know that luan plywood's great structural strength can partially be attributed to its perpendicular layers of veneer.

These veneers are laid back and forth and glued together until a cohesive "sandwich" is formed. OSB: Oriented-strand board looks like large flakes of wood compacted together into a sheet. In fact, that's just what it is: about 50 layers of these "flakes" arranged perpendicularly and sealed together with phenolic resins to make a single sheet.


 Compared to luan plywood, OSB is a relatively new building product. A leading manufacturer of both luan plywood and OSB, Georgia-Pacific, has been making luan plywood since 1964, but OSB only since 1982. How do luan plywood and OSB stack up in major categories? In each category, the "winner" is listed first: 1. Stiffness Plywood. Across equally-spaced joists , luan plywood can be up to 10% stiffer than OSB. 2. Cost OSB. OSB $3 to $5 less per panel. To be exact, using the figures below, OSB is $4.50 less per panel. If you are doing whole-house floor installation, this is a huge difference
