How to install laminate flooring on uneven surfaces

Updated April 17, 2017

Laminate flooring has become a popular choice for many homeowners, who wish to give their floors a stylish finish without spending a lot of money on solid wood floors. Laminate flooring consists of a composite wood plank with a veneer that is printed to look like real wood. It is strong and durable, and many do not notice the difference between laminates and solid timber when laid correctly.

Clear the floor of all previous flooring. For floors with carpet, ensure all underlay and tack strips are removed using a claw hammer.

Clean the floor thoroughly to remove dust and debris by using either a vacuum cleaner or a stiff-bristled broom.

Floorboards or chipboard can warp and move over time, creating an uneven floor. Identify areas of your floor that seem uneven and assess their seriousness, which determines the method used for rectifying this problem.

For floors with only slight pits, bumps or unevenness, fill holes using a wood filler, and grind down any bumps using a sander.

For areas of high damage or unevenness, the floorboards or chipboard may need to be replaced.

Many uneven floors can be rectified through laying an underlayment, such as a thinset compound, which is pumped over the existing floor and then levelled to create an even spread.

Install the laminate onto the set floor. Laminates come in a variety of forms, including those with glued backs, or tongue-and-groove pieces that simply snap together. Leave the floor to settle for three days after use.


A floor sander may be quicker and more effective than using hand-held sandpaper. Lay laminate boards in the same direction as the longest straight wall. Store your laminate boards inside for 48 hours before laying to allow them to acclimatise to the humidity and temperature of the house.


Laminate flooring in wet areas may be more prone to movement and warping. A moisture test should be carried out on flooring before laying. Clean up excess glue as soon as possible to prevent it from drying. Use a block between the hammer and the laminate if hammering is required to avoid damage.
