Clean Surface

This article deals with how to install plywood flooring on concrete and assumes that the surface is flat. A thinning application can be used to patch up holes or even out the surface appropriately.

A clean surface is essential so it must be prepared with acid or a specialized concrete cleaner. This should be carried out in good ventilation and the surface should be absolutely dry before installing the plywood flooring.

Buy the right glue

When purchasing the plywood flooring, seek advice from the retailer or manufacturer about the kind of glue necessary for the job. Using the correct glue is important in order to ensure longevity of the flooring and that the surface performs as it should. This is one of the more pertinent aspects of how to install plywood flooring and should be closely observed.

Cut to measurements

The area upon which you will install plywood flooring should of course be measured and any corners and odd sections should be accommodated. The plywood sheets can be cut to size using a jig saw or hand saw.

Choose your starting area, which should be the most obvious section of the floor so that the large sheets will cover the visible area and the cut-to-size sections will be less obvious. As you radiate towards these sections, cut the flooring as you go, rather than measuring up in advance.

Adhere plywood to concrete

Apply the manufacturer-approved glue to the concrete using a trowel comb and spread evenly. Lay the sheet of plywood over the glue and butt against walls and adjacent sheets.

Take a block of wood to the size of approximately 1 square foot and wrap some fabric around it so that it can be handled easily and also so that the wood does not scratch the surface of the plywood. Use this block to tap the newly-laid plywood to ensure any air bubbles are expelled.


When finishing at doorways, a special PVC or aluminum mold is used to conceal the front edge of the plywood. Calculate your requirements for these moldings and purchase what is required before beginning the installation.

Installing plywood flooring is a job that can be undertaken by one person and is relatively simple as long as the correct materials are purchased and the right advice is sought before commencing.
