Basement Subfloor Installation Requirements

The condition of your subfloor is a key for your floor renovation, especially for the long-term lifespan of your laminate. It helps to transform your space from a slab of concrete/ wood into something more attractive and decorative.

Before laying a single plank make sure your subfloor is appropriate to provide your new laminate flooring an excellent living area.

Standard Requirements for Subfloor

There is no difference what type of subfloor you have or plan to have, it should meet a certain set of standard requirements for basement subfloor installation. Here are a few considerations for you to make before unrolling your underlayment and installing the first plank.

–       Flat surface

In order to support your flooring properly, all types of subfloors must be flat. Acceptable biggest difference between two adjacent high points is 3/16 of an inch. That is not a lot of separation in a 10-foot radius.

If excessive voids or bends in your subfloor are available, level it before starting your installation. Fill low areas or holes with a cement and latex compound. Wait until it dry thoroughly before your flooring is installed.

–       Absence of slopes

There should not be any slopes in your subfloor either. The slope must be fixed if it is larger than an inch per six feet.

–       Clean surface

Your floors can be damaged over time with dirt and debris. Before beginning any type of floor renovation, especially laminate flooring installation, always clean and dry your subfloor.

–       Right choice of material

Carpet or padding are inappropriate materials for basement subfloor laminate installation. The ideal subfloors are made of wood and concrete. It is acceptable to install your flooring over an existing one, but always check prior to installation if the material is suitable for your basement subfloor installation.

Remember, the following materials are not suitable for a laminate installation: glued vinyl, cushioning, residential carpet. If one of these types of flooring is yours, then it should be removed before laminate installation.

The following types of subfloors are appropriate for laminate flooring:

  • Concrete
  • Vinyl that is not glued down to another subfloor
  • Terrazzo
  • OSB board
  • Exterior grade plywood
  • Particle board
  • Existing wood, not adhered to concrete
  • Ceramic

During your installation both subfloors and underlayment deserve as much attention as the actual flooring itself. Keep it in mind and you will be satisfied with a perfect end-result of your floor renovation.
