Preparation for laying wooden flooring

How to prepare a sub floor. A well prepared subfloor is a key to long lasting wood floor. For any kind of wooden floor there needs to be a little bit of preparation.  The floor we will be laying on to is known as the subfloor. You need  this to be smooth, dry, level  and swept clean.

Any carpets that's in the room needs to be removed as well along with the underlay. Grip rods around the outside needs to be removed as well. And the most important is to check floor for moisture.

The easiest option is to stick square meter piece of polythene directly onto concrete floor. Make sure that it is well sealed on all four sides. Leave it overnight. If the concrete underneath changes colour or there is condensation on the undersides of the polythene, this means you will have a moisture problem and you need to sort it out before laying wooden flooring.

If you laying on top of floorboards, make sure these are firmly screwed down. Any nail heads needs to be flattened with the hammer and any gaps must be filled with the flexible mastic filler.

Uneven floors must be flattened out with hardboard sheets or plywood.

If you are laying over existing wooden flooring, mark all the gaps or uneven level s first. Fill the gaps with the filler and sand down high spots to make subfloor even. Make sure there's no nails sticking out as you can break sander or tear sandpaper easily. The best option is to use edge spinner than sander as it will do job much quicker.

It very important to take out high spots before you will lay down flooring. If the wooden subfloor  is very uneven you can use drum sander to make it level.

It is very important to check clearance in a doorways. If a floor plank and underlayment  won't fit under the door casing, cut the casing with the backsaw few millimetres above the flooring.

If the floor plank and underlayment doesn't fit under the door, cut the door with circular saw. Before starting to lay down wooden floor be sure that your floor is

  • Clean
  • Level
  • Dry
  • Structurally sound

Tools you'll need to get started

  • Sander
  • Long level
  • Tape measure
  • Vacuum
  • Level compound
  • Underlayment
  • Staple gun
  • Back saw
  • Circular saw
  • Drill and screws
  • Hammer
  • Pry bar
  • Pencil
  • 1 square meter polythene

Once you have prepared your subfloor, you need to measure room before heading out  to get your flooring and underlay. Measure the length and width of the room in meters and multiply the numbers together to the area of the room in square meters. If you have irregularly shaped room divide it into separate rectangular areas and calculate them individually and then just add them together.

Then you need to work out how many  packs of flooring you need to cover the area. Most packs will tell you how many square meters they contain. You simply divide the size of the room by the size of the pack. This gives you the number of packs needed. Always add around 10 percent to this number to account for any possible mistakes.
