Before installing your new floor, it’s crucial to ensure the subfloor is well prepared. No matter which type of flooring you’ve invested in, it’s going to need to be installed on top of an even, stable subfloor in order to maximise its longevity.
Here, you’ll discover how to prepare a subfloor ready for your new flooring. Whether you’re fitting real wood, laminate or vinyl flooring, you’ll find the appropriate subfloor preparation tips below.
Preparing a Subfloor for Hardwood Flooring
When fitting an engineered wood or solid wood floor it is important to ensure the subfloor is moisture free. After removing your old floor, you’ll typically be left with either a plywood or a concrete subfloor. It’s vital the subfloor is prepared accordingly if you want your hardwood floor to last.
Firstly, you’ll need to give it a good clean. Make sure there’s no dirt, debris or spilled paint on the floor. Then, it’s time to make sure the subfloor is even. If part of the subfloor is higher than the rest, sand it down. If there’s any holes or dips, fill them in. Make sure any compound you use on the subfloor is fully dry before moving to the next step.
If you’re working with a plywood base, ensure none of the boards are squeaky or loose. Ideally, the plywood should be fairly thick as this will add to the stability of your new wooden floor.
You’re also going to want to check the moisture levels. If there is any moisture in the subfloor, it’s going to cause issues with warping and swelling in your floor over time. This can lead to irreversible damage which will be costly to replace. If there is high moisture, consider investing in a moisture-resistant underlay to help protect your new floor.
Preparing a Subfloor for Laminate Flooring
When it comes to laminate flooring, there are certain types of subfloors which aren’t suitable to use. These include cushioned flooring, carpets and glued vinyl. Ideally, you’ll want to work with a concrete, plywood, ceramic or vinyl subfloors which hasn’t been glued down.
The preparation process is pretty much the same as it is for hardwood subfloors. It needs to be cleaned and levelled off to ensure it’s going to provide a stable base. Moisture should also be kept to a minimum, ideally with a less than 12% moisture reading.
Preparing a Subfloor for Vinyl Flooring
Vinyl flooring is known to be extremely durable. However, that doesn’t mean you can get away with a poor-quality subfloor. Even vinyl floors can become damaged over time when exposed to moisture. So, you’ll still need to check the moisture levels of the subfloor prior to installation.
You’ll also need to clean and level out the floor if required before fitting the vinyl. As an additional side note, if you’re installing floating vinyl, you’ll need to add a vapor barrier if you’re using a concrete subfloor.
If you’re installing the vinyl on a plywood subfloor, you’ll usually need to add an extra layer of wood to ensure it’s thick enough. Vinyl is a lot thinner than laminate or hardwood flooring, so you need to ensure the subfloor is thick enough to add plenty of stability.
As you can see, no matter which type of flooring you’ve invested in, the preparations for the subfloor are pretty much the same. Ensuring it’s clean, level and dry enough is the key to ensuring your new floor really lasts the test of time. You’ll find many new floors come with instructions on how to prepare the subfloor to match the new floor’s requirements. Always follow these as closely as you can to ensure best results.
