SPC Flooring Installation Guidelines

SPC Flooring Installation is quite easy. 

Many people may worry about this before buying the SPC floors. 

You can finish the DIY installation by following these guidelines.


1. Please carefully examine the grade, color, surface, and the locking quality of the flooring. 

Make sure a proper examination takes place under a circumstance of enough light. 

Do not continue to install the flooring if it is unqualified. 

Please contact the dealer immediately to exchange the products.

2. Get the tools you will use in the installation: utility knife, straight edge, tape measure, spacers, pull bar, miter saw, and string line.

3. Do not take out the planks of the cartons in the room where the installation will proceed. 

Ensure at least three days for the SPC flooring to acclimate the new environment. 

4. The room temperature must be maintained between 18°C and 29°C. 

The air humidity should be lower than 65%.

5.When calculating the area that the flooring may cover, please reserve at least a 10% margin. 

If you need to install diagonal or other patterns, please reserve at least a 15% margin.


Like hardwood flooring, it is necessary to make a proper sub-floor preparation before SPC Flooring Installation. 

1. Whatever are the installation methods, all sub-floors must be clean, smooth, and dry. 

If the SPC flooring is installed on an uneven sub-floor, it may squeak when walking on it.

2. Sweep the sub-floor and make sure it is free of grits, debris, and any adhesive residue, which may affect the installation.

A. Wood Sub-Floors 

1. SPC flooring can be installed over plywood, OSB, flake board, and wafer board. A 15mm thick plywood is recommended.

2. All wood sub-floors must be smooth and dry. Any unevenness over 3mm and hollow must be sanded down and filled in.

3. Never install SPC flooring over any wood flooring that directly lay on the concrete.


B. Concrete Sub-Floors 

1. Level the concrete sub-floor before installation as most of the surface of concrete floors is not completely smooth and flat. 

2. Use patching compound to fill in hollow and seams on the concrete sub-floor. Any unevenness can cause looseness and damage to the locking system of the floors.

3. The concrete sub-floor must be clean, dry, and smooth. Please sweep with a vacuum to ensure it is free of substances or debris. 

4. For the best installation, the moisture level of the concrete floor shall never exceed 5%.



Never install the SPC floor over the carpet or any preexisting vinyl flooring.

Never install the SPC floor over the soft, deformed sub-floors, which will damage the locking system of the floor.


Please read up the following instructions before installing the floors. 

1. First of all, plan the layout of the flooring before the installation. 

Start placing down the planks from a corner of the room. 

Do not secure them, but check if you need to adjust the layout. 

2. Installation must start from the left to the right of the room. 

Lay the first plank in the upper left corner of the wall, letting its grooved edge facing towards you. 

Use spacer between the wall and the plank's edge, always allowing a gap at least 4mm for an expansion joint between the floor and the wall.

3. Then, place the end of the second plank, interlocking it with the end of the first plank. 

Use a rubber mallet to tap the joint softly, ensuring a firm locking.

Continue in this way until reaching the final plank of the first row.

4. For the margin of the last plank in the first row, use the ruler to mark a line for the part you will cut.

Use a sharp utility knife to cut constantly on the same line.

Only cut deeply but do not cut through the plank.

Add pressure to push down the cut with one of your hands while raising the other half of the plank with the other hand.

The plank is split into two parts according to the cut line.

5. To begin the 2nd row, when using the left-over part from the final plank of the first row, always allow at least 8'' between end-joints of the previous row to the row you are ready to install. 

If not, you should cut off a new plank with a minimum of 8'' in length to begin this row.

6. Later, interlock the first plank of the second row into the installed row with a 30-degree angle.

Similarly, use the rubber mallet to tap the joint softly after putting down the plank.

Check if they are at the same height to judge if you install properly.

Please make sure they are well aligned before starting the next row.

7. For an ideal installation result, the following rows should be staggered.

For example, cut the first plank of the second row into 2/3 of its original length.

Cut the first plank of the third row to 1/3 of its full length.

Use the rest of the pieces at the end of each row.

8. Use a string line to examine the straightness when 2 or 3 rows are done.

If the planks are not going straight, you need to trim the first row to adjust. 

9. Continue to install in this way until the final row is done.

The last plank of each row should be cut to its correct length when reaching the final plank in each row.

10. To replace the molding, please make sure a slight gap between the molding and the planks.

Nail the molding into the surface of the wall instead of the flooring. 

11. At last, use a wet mop to remove residual dirt on the flooring surface after 48 hours.
