Step-by-Step Instructions For:

Gluing Tongue-and-Groove Boards on Concrete

Glue joints between boards, using wood adhesive in the grooved edges. Avoid going too deep into the recess (Image 1).

Spread a commercial adhesive on the floor, using a notched trowel to groove it for better adhesion (Image 2). Press the boards firmly in place.

Continue gluing the boards and pressing them into the adhesive. The weight of concrete blocks will help to push down the boards as they dry (Image 3).

Laying Nailed Tongue-and-Groove Flooring

If you plan to cover a large floor area with strip flooring, the job will be much faster, and easier on the knees and hands, if you use a pneumatic flooring nailer, which is available for rent at most home improvement stores. When selecting a floor nailer, review the safety features.

Remove baseboard, loosening it with a pry bar before pulling it from the wall. Sweep away debris. Apply self-leveling compound if required (Image 1).

Lay vapor barrier, with an overlap of 6 inches up the wall. Fold it in the corners to allow it to sit flush on the floor (Image 2).

Attach furring strips around the room with 4-in (100-mm) concrete screws. Fix furring strips every 16 in (400 mm) at a right angle to the new boards (Image 3).

If furring strips do not lie level, use shims or offcuts to pack out any indents and level the furring strips (Image 4).

Start laying boards, and attach with toe nailing into the furring strips. This is done by securing a nail at a 45-degree angle into the tongue (Image 5).

Drive the nail through the board and into the furring strip, so the head is just beneath the board’s surface (Image 6).

Continue laying boards. Once the floor is complete, apply any finish (e.g., wax or varnish) that may be required. Trim off the membrane overlap with a utility knife. Replace the baseboard to cover the expansion gap (Image 7).

Laying Parquet Tile Flooring

Attach two temporary furring strips to the floor to mark a starting point (as you would for laying hard floor tiles) (Image 1).

Spread enough adhesive inside the angle of the furring strips for the first two or three tiles. Use a notched trowel, or the tool supplied (Image 2).

Press the first tile into position, bedding it into the adhesive. (Some manufacturers specify that the adhesive should be allowed to become tacky before you position tiles.) Check that the edges of all tiles are precisely aligned as you work across the floor. As with other tiling jobs, lay all the full tiles first (Image 3).

Wood tile adhesive can be solvent based, so make sure the room is well ventilated.

Remove the furring strips with a claw hammer to prepare the edges of the room. Then fill the gap with cut tiles (Image 4).

Measure for cuts as for other tiles. Wooden tiles are easy to cut with a fine-toothed saw. For curved cuts, use a jigsaw (Image 5).

Apply adhesive and place the cut tiles in the gaps to complete the floor and press them into position (Image 6).

Finish off by filling the expansion gaps with cork strips. Replace baseboard or apply edging. Seal the tiles if required (Image 7).
