Can You Stain Luan Plywood?

Can You stain Luan Plywood? 

Yes you certainly can stain Luan Plywood to give it a more finished appearance. How do you do this you ask? Well here is a quick guide for you:


Staining Luan Plywood

 When Staining Luan Plywood your first step should include taking a look at the surface of the plywood for any scratches or defects.

1. When applying the wood putty to fill unsightly scratches or gouges or voids in the plywood edges. Let putty material set and then follow application using to manufacturer's directions.
Smooth the surface of the plywood, and sand if necessary to complete the polished look of the material.

2. Second you should focus on sanding the luan plywood and applying a veneer coat on the wood. You can use a machine sander to assist with the job. If you are not able to use a machine sander or an orbital sander you can use sanding paper to prepare the plywood for the staining solutions. You can apply a primer to the luan wood, using steady coats. Once the main primer has dried, you are ready to begin the next step. 

3. When this has been completed, your next step should be to wipe any residual stain off your plywood so that the finish is even. Then wipe parallel to the grain to ensure a nice look. It will also help to stop any streaking from appearing on the wood. Allow the plywood to dry. Then go to the next step.  If there is any unevenness, apply another coat, and then sealer of lacquer or finish to give it a quality and professional look.

4. Give it a day or so and then if you want to deepen the colour of the plywood you can apply a second coat before moving forward, or beginning the process again. Allow the polyurethane to dry for at least 8 hours or more before moving forward with additional coats.


Luan Plywood is usually manufactured in 4 x 8 foot sheets. And Luan panels are good subfloors for Hardwood flooring, as long as they are the proper thickness.

You should remember that for mechanically fastened floors, as well as plywood, you need to use a thicker material to get the same holding power. In general, the minimum thickness for Luan plywood is 1/8 inch and sometimes 1/4 of an inch.

  However, as the joist spacing increases, the subfloors needs to be thicker. For joist spacing of more than 16+ inches to 19.2 inches on center, the minimum thickness for both Plywood is 3/4 inch.





For joists spaced more than 19.2 inches on center, the minimum thickness for Luan Plywood is 7/8 inch.

So, here are the main steps to make your Subfloor even.



1. Have a List Before Installation:

  Once you get the subfloor into the proper thickness, you must check that the subfloor is properly installed. It must be installed with no issues that could affect your installation. Subfloor panels and fasteners should also be properly placed according to the panel manufacturer's specifications.

If there are protruding fasteners, squeaks or loose panels, you should refasten the subfloor to the joists. The subfloor should also be cleaned and free of contaminants such as paint, sealer or drywall compound.


2. Check Around the Subfloor:

  Now, check from below the subflooring and note the direction of the joists. With the above notes, the flooring should be installed perpendicular to the floor joists.

The subflooring can be laid parallel to floor joists, but you may need to add a 1/2-inch layer of plywood diagonally or perpendicularly to the joists, or install a brace between the joists.


3. Make Sure your Subfloor is Even:

   Ensure the subfloor is even to the recommended strength for the flooring that you are installing. For installations using mechanical fasteners that is 1+1/2 inches and longer, your subfloors should be within 1/4 inch in 10 feet or 3/16 inch in 6 feet.   Installations of those with mechanical fasteners on the Luan plywood using less than 1 1/2 inches, the subfloor should be within 3/16 inch in 10 feet or 1/8 in 6 feet. The subfloor can be flattened by sanding down the high areas or by installing shims such as roofing shingles or various thicknesses of plywood. 


4. Moisturizing:

   Another critical part of the subfloor inspection is to check the moisture content (MC) of the subfloor and the joists. Luan Plywood is not especially well suited to moisture exposure
