Wood flooring jargon
Learn how to tell your screed from your underlay, cut through other DIY jargon, and choose the right tools and material to lay wood flooring.
This is often a liquid, such as latex, that is applied and spreads out to create a level surface. When it hardens you are able to lay your floor over it. It's used to level uneven floors.
Damp-proof membrane (DPM)
This plastic sheeting is essential when laying laminate or wooden boards over a concrete or sand and cement floor. It prevents moisture moving up into the boards, which would cause them to warp.
Prices start at 59p per sq m, up to around £1.50 per sq m in DIY stores. Heavy-duty DPM by Visqueen is a professional-grade choice.
This is fixed to the floor with nails to create an even surface to lay the floor on. It provides sound insulation and increases the floor’s durability.
It can either be a thick, recycled paper board costing around £2-£3.50 per sq m, which provides good sound insulation; or multipurpose wood boards, such as hardboard or plywood, costing from £1 per sq m.
This is used to cushion the flooring boards, increasing their durability and providing sound insulation.
There are several different grades, which range from thin sheets of closed-cell polythene foam, costing from £1 per sq m, to top-of-the-range felt underlay with a silver foil layer, costing around £6 per sq m.
This describes the way the planks fix together. A tongue that projects from the side of one plank fits into the groove of the adjacent plank.
These have shaped edges that require a certain sequence of actions to fit them together, but once they are in place they can’t move apart.

A plastic block that is used to protect floor planks as they are hammered together. Rather than hammering the edge of the plank directly, you hammer the block, so you can’t damage the plank with the hammer.
A handy tool used to drive glued planks tightly together at the tongue-and-groove joints. This tool is especially helpful at the wall when driving the end tongues and grooves together, where it is not possible to use a tapping block.
Wedges and spacers
Use these to maintain the expansion gap around the perimeter of your room when laying laminate and solid wood flooring. Also useful for creating a straight edge against a wobbly wall to give your floor a good start.
This is used to glue tongue-and-groove boards together and to fix beading or skirting in place above the edge of the floor.
Some modern adhesives for fixing solid floorboards to a sub-floor expand as they dry, filling small voids under the boards and ensuring that they don’t sound hollow when you walk on them.
Radiator pipe roses
These ring-doughnut-shaped pieces of wood or plastic are used to cover the expansion gaps left around radiator pipes.
Wood floor plank features
The edges of some laminate flooring turn downwards to create a more realistic boarded appearance. It also helps to avoid damage caused by moisture-induced swelling at the edges of laminate boards.
Wood flooring expands in a humid room and contracts in a dry one. You’ll need to leave a 10-12mm gap around the edge of your floor.
This manufacturing technique creates laminate flooring planks that have a slightly three-dimensional finish.
The core of the laminate is increased or reduced to correspond with where the image shows a feature, such as a knot or strong grain in a wooden plank.
You can therefore feel, as well as see, where the grain would create the texture in a real wood plank.
