Installing A Ply-Wood Tile Underlayment
Is Fairly Easy And It Makes For A More Professional Looking Floor Tile Installation.


Ply-wood makes for the perfect floor tile underlayment, It gives you a nice smooth even surface that's Quick and easy to install. And it makes your  new floor tile installation look much more professional.

It's the perfect tile underlayment for a  floor tile installation that includes Cork floor tiles, Vinyl floor tile, Laminate floor tile, Parquet floor tile and in some cases even Stone and Ceramic floor tiles.

About A Plywood Tile Underlayment

* A plywood underlayment must be smooth and free of debris. And especially when it comes to installing Vinyl floor tile. Because with a vinyl floor tile installation no matter how small the lump or bump underneath it will show right through the vinyl floor tile.

*  Stone and Ceramic Floor tiles can be laid to a plywood tile underlayment as long as it's not in a damp area.

* Never use plywood for a floor tile installation using Stone or Ceramic floor tiles in damp areas or where the tiles will be exposed to water such as in a bathroom, kitchen or laundry room.

* If you'll be installing Stone or Ceramic floor tiles in moist areas it's always best to use a cement backerboard tile underlayment.

Measuring the thickness of your Subfloor

When you use ply-wood as your floor tile underlayment, you'll want the subfloor underneath to be 1-1/4 to 1-1/2 inches thick. If your subfloor doesn't measure up, you can just add the needed thickness by adding extra layers of plywood to build it up to par. So, If your current subfloor is 3/4 inch add 1/2 or if you choose 3/4 inches of plywood on top of it.
Then you'll have the 1-1/4 or 1-1/2 thickness you need to lay your plywood tile underlayment on top.

Building up your Subfloor with Plywood is Done in the same way as Installing a Plywood Tile Underlayment found below.

Finding The Thickness

To find the thickness of your subfloor, find a plumbing pipe or heating duct, that passes through the floor.
If you can get a tape measure or any other object through this hole, you can get the thickness of the subfloor from this. Otherwise, you'll have to drill a small hole through the subfloor and stick an object through this hole.

Installing A Ply-wood Tile Underlayment

What You'll Need

Enough Ply-wood Boards To Cover The Entire Floor

*A Hole Saw

*A Power Drill

*A Circular Saw

*Wood Shims

*Two Saw Horses Or Four 8 foot 2x4s

*Construction Adhesive

*Wood Screws

*Tape Measure

Step 1- Adding your Tile Boards

Use wood shims to create a 1/4 inch gap around the perimeter of your floor. Starting in a corner lay your first sheet of plywood and continue laying these boards until the entire floor is covered.
Do not attach your boards to the floor at this time.

Step 2- Cutting your Boards

You will probably need to cut some ply-wood sheets to make them fit comfortably into your tile underlayment pattern. So you'll need first to Mark your plywood boards for cuts.

Now that you've marked your boards for cuts, Set the depth of your circular saw to just a hair beyond the thickness of the plywood.
Set the plywood across two saw horses, or four eight foot 2x4s. Spread the 2x4s evenly under your board, and then cut the plywood boards on your intended cut lines.
Repeat this process as needed while adding your boards to the floor one at a time

Making holes in your ply-wood boards

If you need to make holes for plumbing pipes, heating vents or other penetrations, use your tape measure to measure and transfer the locations for the holes to the ply wood board. Use a hole saw loaded into a power drill or jigsaw for cutting out the holes.

Step 3- Fasten Down Your Boards

Now that all of your plywood boards are  laid they should form a nice tight surface on the floor. Pick up your first board and apply construction adhesive on the subfloor underneath.
Lay the board back down on top of the glue and fasten it to the floor with wood screws. Continue this same process with all of the boards on the floor, until they are all laid and fastened.

Be careful that your screws are long enough to go through the ply wood, and down through the depth of the the sub floor.

Finish off your plywood tile underlayment

Finish off your Plywood tile underlayment by mixing up a batch of Latex Reinforced floor patching compound to the consistency of toothpaste.

Check with your seller to make sure the patching compound is compatible with the tile adhesive you'll be using.
Use a flat trowel or taping knife to fill all the fastener holes and seams between the plywood sheets and then scrape it flush with the surface. Allow the compound to dry overnight and in the morning use a sanding pad loaded with medium grit sandpaper to sand any patches smooth.

Once you're done you'll have a new tile underlayment that's perfect for your new floor tile installation.
