Laminate flooring can be laid directly on concrete, plywood, OSB, hardwood, vinyl and tile. The subfloor must first be applied to the original floor covering, after which the laminate floor can be laid.
The best substrate for laminate flooring is foam or cork. The best backing for laminate flooring is foam because it is easy to lay, offers good sound insulation and is very economical. Some of the best foams have an extra layer that acts as a better moisture barrier.
However, if you’re used to other types of flooring such as hardwood, wood-based panels, vinyl, and tile that don’t require a subfloor, you might be surprised to find that a subfloor is practical with laminate flooring.
Wood and concrete are ideal substrates. Good laminate floors are:
- High quality plywood for outdoor use.
- OSB panel.
- Concrete (which is at least one month old)
- Existing wood that is not connected to concrete.
- Vinyl that does not stick to any other subfloor.
Plywood subfloor: When laying laminate flooring over plywood or OSB subfloors, a breathable foam subfloor is often used. The exception is when laminate flooring is installed in a room with high humidity, such as a bathroom or basement, where a moisture barrier makes sense.
Laminate floors are a must. Since laminate is a floating floor, it must be evenly distributed over the subfloor. The subfloor allows the floor to float, provides stability, support, noise reduction and supports interlocking systems between the boards to ensure the strongest flooring design.
While laminate flooring is a glue-free floating installation system, glue is used as a barrier to prevent moisture from entering a joint and core where two laminate floors meet. Eliminate the liquid as quickly as possible, even if the boards are glued.
The subfloor should be:
Fill Holes in Plywood Underlays
If desired, a chipboard subfloor can be left if a parquet or laminate-laminate system is laid on it. BUT the extra height of the chipboard and new flooring can be a problem with doors and appliances.
There should be no lumps or bumps. In no case greater than 1/8. You can paint the high points and fill the low points with self-leveling material.
How to use roofing felt for subfloors on laminate floors. Laminate floors can be installed on any existing hard floor surface, but must have a subfloor between the laminate floor and the subfloor. You can buy laminate flooring, but if you have a bunch of old roofing felts it works just as well.
It is usually 3mm thick or 1/8 thick. Standard range. It is the most commonly used interface. It is also 3mm thick (1/8 thick) and is best installed on wooden floors.
Most surfaces offer additional padding for a floor. If this additional infill is combined with the pre-installed infill on the laminate floor, this poses a risk and should be avoided. By adding unnecessary padding, you can actually do more harm than good to the floor.
Moisture can cause laminate floors to shrink or swell slightly. These fluctuations in humidity can cause them to break and move, creating gaps between the panels. Fortunately, it is not necessary to remove all of the flooring to close these open joints.
Many homeowners wonder whether it is advisable to seal laminate floors. The short answer is yes, but there’s more to this task than just taking a standard can and painting it on your new laminate. When properly sealed, the laminate is more resistant to splashes and more durable.
All laminate floors require support so that the floor can float and give the locking system its strength. Depending on the support and the project, specific support will be required. When laying, a moisture-resistant subfloor is required: on a concrete floor.
