 How to fit Underlay 


 

Underlay is incredibly easy to lay and fit yourself and thanks to our trusty DIY experts who have first hand experience of fitting underlay, you can do it too. Whether you are installing carpet underlay, laminate or wood underlay or underlay that is safe to use alongside underfloor heating, this fitting guide will help you along in the process without leaving you lost or confused.

Take note of the safety tips and tool kit to ensure you are fully prepared to take on the task of fitting your underlay as well as carrying out all necessary preparation and cleaning processes beforehand. 

If you are unsure of how many rolls of underlay you need to cover the surface area of your room, head to our measurements guide to help you prepare for your new flooring. Take a look at our floor fitting guides after you have carried out the installation of your underlay to begin your next DIY project!

 

 


Step 1


  

Preparing for your Underlay

1.Prepare for the underlay fitting process by gathering all necessary tools before starting and reading over your measurements.

2.It is important to have a clean, dry and even surface to work on when installing underlay. Sweeping the subfloor will allow for no bumps or dirt to alter the overall appearance of your flooring when you have completed the installation process.

3.Double check that you are using the right underlay that is suitable for use alongside your chosen flooring. The products description details will inform you on the appropriate flooring types that you can use alongside  your chosen underlay, whether this be laminate flooring, carpet, or wooden flooring.

 

 


Step 2


  

Rolling out your Underlay

1.Position your underlay in the preferred direction you would like to lay it in and roll out the material towards the opposite side of the room.

2.Ensure you push each roll of underlay tightly together, leaving no room for gaps or movement. Push the underlay all the way up alongside the grippers (for carpet underlay) or skirting (for laminate and wood flooring underlay) to secure a tight fit.

3.Attach the rolls of underlay together using duct tape to secure the material and prevent any unwanted shifting beneath your flooring.

 

 


Step 3


  

Secure your Underlay

1.Once the underlay is attached and has formed one piece of material, you can begin to apply the adhesive to the underside of the underlay.

2.Depending on which type of subflooring you are laying your underlay onto, the form of adhesive you use will differ. On most surfaces, tape or spray adhesive will work or if you have a less firm surface to work with, you can opt for a staple gun.

3.Work around the outside of the underlay, attaching each edge to the sub floor. This will ensure you create a secure bond to prevent the underlay from moving beneath the flooring once it has been installed.

 

 


Step 4


  

Trim your Underlay

1.Work around the edges and trim the underlay to fit tightly around the perimeter of the room.

2.For a more precise finish, measure and mark the underlay with a pen to provide you with a line to accurately trim along the material.

3.Be sure to leave any necessary gaps around pipework or indents within the room. We recommend 10cm for carpet underlay and 15cm for laminate or wood underlay.
